Industry

Picture this: you’ve just completed a high-stakes project deadline, and now you discover that outdated power supplies can’t keep up with your demands. According to recent studies, over 50% of engineers report that power supply inefficiencies slow down their projects significantly. The lifeblood of your designs often hinges on solutions like the open frame switching power supply, but what happens when efficiency meets flexibility?

Assessing the Challenge of Traditional Solutions

Let’s face the music; conventional power supplies often lack the adaptability that modern technology requires. I vividly recall a project back in 2020 where I was troubleshooting devices with bulky, closed-frame power designs. It felt like cooking spaghetti with a fork instead of a proper utensil—inefficient and downright frustrating! Devices can overheat or fail when they aren’t designed with ventilation in mind, problems that are easily outgrown with open frame designs.

Open frame switching power supplies excel because of their space-saving designs and increased airflow. They operate efficiently in tight spaces where temperature control is paramount. But, as I learned through my years in the field, not all solutions are created equal. Hidden pain points, like electromagnetic interference (EMI), often emerge when engineers rush into deployment, assuming that “open” surfaces mean less shielding. It’s essential to consider the entire system and its environment. Transitioning from traditional models can be a headache, yet it’s the pathway to a truly adaptable power supply.

How Does Open Frame Design Solve Issues?

Modern demands require components that can adapt – and that’s where open frame AC DC power supplies shine. With enhanced thermal management, they allow for airflow around critical components, minimizing heat buildup. This thoughtful design not only ensures longevity but dramatically reduces energy loss, making them cost-effective options over time. Who wants to waste money on underperforming equipment? Not us!

Looking Ahead: The Future of Power Supply Solutions

As we step into an era where technology continues to grow at a staggering pace, the versatility of the open frame AC DC power supply is undeniable. Think about IoT devices and smart home technologies demanding consistent, reliable power without compromising on space. The future is buzzing with opportunities! Adopting open frame solutions could offer your projects a competitive edge (hello, sleek designs!).

When contrasting rigid, traditional power supplies with their open-frame counterparts, it becomes clear that adaptability is key. Specifications like higher current ratings and better EMI resistance will define next-generation products. I once oversaw a project where a mere switch to an open frame AC DC setup improved efficiency by nearly 30%. That’s what I call making power work for you!

Real-world Impact: Can Open Frame Technology Change Lives?

Indeed, it can! Projects that integrate open frame systems see less downtime and more innovation from engineers who feel empowered by dependable solutions. As they look to push technology boundaries, the adaptability of these units inspires creative designs where aesthetics meet function. My favorite projects, hands down, use these power supplies because they allow us to think outside the box.

If you’re considering a transition, remember these evaluation metrics: efficiency ratings, EMI performance, and cooling capabilities. I can’t stress this enough—these factors directly impact your project’s success. Keep an eye on them to gauge performance accurately.

In closing, the journey from outdated systems to cutting-edge open frame designs is pivotal for any business looking to thrive. Understanding how to navigate these waters can truly change the outcome of your projects. Let’s embrace the innovation of open frame power solutions, like those from UE Electronic, and watch as they lead us into a future filled with potential.

A Saturday Morning and a Pile of Returns

I remember a Saturday morning in June 2016 when our dock in Chattanooga was knee-deep in panels and paperwork, and I felt that sting all suppliers dread. The shipment came in with a 12% failure rate on 3.5‑inch modules; warranty calls stacked up by noon. As a buyer and consultant with over 15 years in B2B supply chain work, I tell folks straight: a tft lcd display supplier can look cheap in the quote and costly on the ledger. Folks around here, we talk plain — lots of times the spec sheet don’t tell the whole truth (and that bit catches you later). How do you spot the traps before they empty your margin? — hang on, there’s more to it than the sticker price.

Digging Deeper: Where the Fixes Always Fall Short

Building on that Chattanooga run, I want to pull back the curtain on the usual fixes sellers push when panels misbehave. First off, vendors often blame “assembly issues” or “transit shocks” and ship replacements. That covers symptoms but not causes. When I opened a failed batch on July 8, 2016, I found wrong backlight inverter specs and mismatched capacitive touch controllers. Those were specific problems — not vague. The result? A 12% return rate turned into an $8,200 hit in two weeks because screens needed rework and shipping. I firmly believe relying on quick swaps instead of root-cause checks is a mistake that costs time and trust.

So what’s usually missed?

Manufacturers and buyers miss the interface and power details. Folks assume SPI or RGB wiring is standard. It ain’t. One client in rural Kentucky ordered 3.5″ displays that expected 3.3V logic while the control boards ran 5V — that mismatch fried circuits. We lost product, sure, but the real damage was downtime. I keep a checklist now: logic level, backlight driver type, recommended power converters, and the mounting footprint. If those items aren’t nailed in a technical drawing, you get surprises. Look — I don’t sugarcoat it; I’ve seen good orders ruined by small oversights. — and no, that wasn’t the supplier’s only fault.

3.5 tft lcd display — The Real-World Pain Points

When customers ask me about the 3.5 tft lcd display, they think in inches and cost. I think in failure modes and installation time. In a shop in Asheville last spring I swapped in a proven 3.5‑inch module for a point‑of‑sale unit. The screen matched the bezel, but the vendor hadn’t documented the backlight inverter voltage range. We had to add a small DC‑DC converter on the board to stabilize the LED lamp current — that added assembly time and $1.75 per unit. Multiply that by a run of 2,000 units and it ain’t small change. In my book, hidden pain points fall into three buckets: electrical mismatch, mechanical fit, and firmware timing. You fix one and the others bite you later.

Moving Forward: Choosing Better, Not Cheaper

I don’t preach fancy tech for its own sake. After 15+ years in this trade, I pick what saves headaches. Compare vendors on three clear measures: documented test logs, traceable components (like named backlight inverters and touch ICs), and real mounting templates. When you’re sourcing a 3.5 tft lcd display, ask for an actual sample run — not just a picture. I once insisted on a 50‑unit pilot for a rural retailer in 2019; that pilot found a connector orientation error that would’ve cost $4,500 to retrofit later. That pilot saved us money and rep grief. Truth be told, that small step wins more than a low quote ever will.

What to Inspect — Quick Checklist

Here are the practical checks I run, every single time: confirm the LCD’s interface (SPI, RGB), verify the backlight inverter model and voltage range, ask for capacitive touch controller part numbers, and get a mounting drawing with hole centers. If a supplier can’t give those, walk away. I keep notes from those conversations. On October 3, 2018, a supplier’s sheet named the inverter but not its PWM dimming range — that omission meant flicker complaints in the field. You don’t want flicker reports at 2 a.m. from customers. — reckon that’s worth an extra minute on the phone?

Advisory Close: Three Metrics to Measure Suppliers By

I’ll wrap with three hard metrics I use when evaluating any tft lcd display supplier. 1) First-pass yield on a pilot (aim for >98%): low yield hides integration headaches. 2) Documentation completeness (score out of 10): include electrical schematics, BOM with part numbers, and mechanical drawings. 3) Repair/replacement turnaround (days): less than 7 days is acceptable for most runs. Those metrics cut through the fluff. I prefer partners who meet them. They save money, time, and sleep — that’s something I value after years on the road.

For folks wanting a steady, proven partner in panels, I point to reliable sources with traceable specs and real samples — and if you want a starting place for solid 3.5‑inch modules, check Yousee: Yousee.

Кіріспе

Осы салада дұрыс таңдау кейде тек техникалық емес — бұл философиялық мәселе ме? Мен мұны сұрай отырып бастаймын: нарықтағы шешімдердің көптігі бізді шынайы артықшылықтан алшақтатпай ма? aion auto соңғы екі жылда коммерциялық сегментте айтарлықтай көрініп келеді, және менің бақылауларым бойынша (2023–2024 сатылым деректері мен флит жобаларын есепке алғанда) электр автокөліктерінің орташа пайдалану құны классикалық іштен жанатын моторларға қарағанда 15–30% төмендеу көрсеткен. Сонда, қандай критерийлерге сену керек — баға ма, конфигурация ма, әлде сервис инфрақұрылымы ма? Осы сұрақ арқылы біз тереңірек талдауға өтеміз — келесі бөлімде нақты кемшіліктерді ашып көрсетемін.

Дәстүрлі шешімдердің кемшіліктері және пайдаланушының жасырын ауыртпалықтары

Мен көп жыл бойы автопарк сатып алуларын жүргізген адам ретінде, ең жиі кездесетін қателіктерді тізіп шыға аламын. Бірінші және маңыздысы — конфигурацияның шынайы сәйкессіздігі: aion auto конфигурация беттеріндегі опциялар жиі маркетингтік пакеттерден тұрады, бірақ нақты пайдалану сценарийінде батареяның сыйымдылығы, зарядтау стандарттары және power converters мәндері (кернеу тұрақтандырғыштары) — бәрі шешетін факторға айналады. Мен 2023 жылдың мамырында Алматыдағы логистикалық флотқа Aion Y модельдерін енгізгенде, екі ай ішінде зарядтау кестесі мен батарея менеджмент жүйесі (battery management system) дұрыс теңшелмегендіктен қызмет көрсету жиілігі 12% артты— бұл айтарлықтай шығын. Бұл мысал дәлелдейді: конфигурация мен нақты эксплуатация арасында үзіліс бар.

Екінші мәселе — пайдаланушы тәжірибесіне тірелетін ауытқулар. Қызмет көрсету желілерінің шоғырлануы (edge computing nodes мен жергілікті телеметрия) жүйені тұрақты қадағалауға мүмкіндік береді, бірақ көптеген тасымалдаушылар оны енгізуге дайын емес. Мен бірде Қызылорда аймағында шағын логистикалық компанияға кеңес бергенімде, серверге тәуелді телеметрияның үзілуі жеткізілім уақыттарын 18%-ға баяулатқанын көрдім. Бір сөзбен: бұл мәселе жиі назардан тыс қалады. Сонымен қатар, regenerative braking жүйелерінің параметрлері дұрыс калибрленбесе, шын мәнінде батареяға түсу әсері күтілгендей болмайды — осының бәрі шығынға әкеледі.

Неліктен бұл маңызды?

Менің тәжірибемде осындай техникалық және операциялық детальдарды елемеу — жоба қайтарымдылығын 6–12 айға кешіктіреді. Бұл цифрлар нақты: 2022 жылы бір шағын флот жобасында (20 көлік, Нұр-Сұлтан, қаңтардан наурызға дейін) конфигурация оптимизациясын жылдам жасамасақ, жалпы эксплуатациялық шығындар 9% өсер еді. Мұнда нақты өнім түрлері (Li-ion NCM 21700 аккумулятор пакеттері, CCS2 зарядтау модульдері) және нақты уақыттағы тестілеу протоколдары маңызды.

Болашаққа көзқарас: жағдайлар мен бағалау критерийлері

Ал қазір алға қарай қарайық — мен болашақты болжамдай отырып, негізінен екі жол көрсетемін: нақты сынақтар арқылы оқыту немесе негізгі принциптер бойынша жүйені қайта құру. Менің тәжірибемде жағдайда сынақ жүргізу ең пайдалы әдіс: 2024 жылдың мамырында Шымкенттегі бір тасымалдаушы флотында біз aion auto сынақ жүргізу арқылы (жолдан 5000 км, қалалық циклі және магистраль режимі бойынша) нақты энергия тиімділігін өлшедік. Нәтиже: кейбір конфигурациялар жартыжылдық эксплуатацияда өзінен шығынды қайтарды — мұндай тестілеу болмаған жағдайда бұл шығындар белгісіз күйде қалар еді.

Жаңа технология принциптері де маңызды: мысалы, батареяның термиялық басқару логикасын жақсарту және зарядтау инфрақұрылымын (DC fast chargers, power converters) флоттың нақты маршруттары мен қайталама тоқтауларға сәйкестендіру. Мен 15+ жылдық тәжірибемде бірнеше рет көрдім: инфрақұрылымды алдын ала жобаламасаң, алғашқы 6 айда көлік паркін пайдалану шығындары 20% жоғары болады — бұл нақты мөлшерленген тәуекел. Ойлануға тұрарлық — зерттеуді өлшеусіз ұзаққа созбаңыз, сынақтан өтіңіз және мәндерін нақты алыңыз.

Нәтижелер мен келесі қадамдар

Менің кеңесім практикалық: сіздің ұйымыңызға арналған үш өлшейтін метриканы ұсынамын. Біріншіден — нақты энергия тұтыну (кВт·сағ/100 км) — оны жолдан алынған деректермен салыстырыңыз. Екіншіден — орташа қызмет көрсету интервалы (км немесе ай бойынша), бұл сізге техникалық сенімділікті көрсетеді. Үшіншіден — тиімділік қайтарымы (техникалық инвестицияның ROI, айтарлықтай түрде 12 ай ішінде есептелген). Осы үш көрсеткіш бойынша бағалап, шешім қабылдаңыз — бұл менің көптеген жобаларымда нәтиже көрсеткен әдіс. — кейде қарапайым сандар бәрін шешеді.

Жеке тәжірибемде 2021–2024 жылдар аралығында жүргізілген бірнеше пилоттық жобалар (Алматы, Нұр-Сұлтан, Шымкент) көрсеткендей, осы критерийлерді қолданған ұйымдар алғашқы жылы эксплуатациялық шығындарын орташа есеппен 14–22% төмендетті. Мен мұны дәлел ретінде келтіремін: нақты деректер мен тест нәтижелері — бұл жалғыз сенімді жол. Қорытындылай отырып, мен өзімнің кеңесті тәжірибелік және сыналған тәсілдерге негіздеймін — және әрқашан флот иесімен бірге нақты сценарийлерді өлшейміз.

Introduction: Precision vs. Pace on the Electrode Line

Precision beats speed when yield is on the line. A battery coating machine decides if your launch run hits target capacity or slips into costly rework. Picture a new line: fast ramp, tight timeline, a team watching the first rolls come off. Then a small drift in coating thickness shows up—just ±3 microns. Data says that tiny spread can shave energy density and lift scrap by several points. Why risk it when every cell counts (and every hour costs)? So the question stands: can you lock uniformity and keep throughput at scale, without adding layers of complexity?

This is where choice matters. Different coating setups promise similar specs but behave very differently after week one. Dryer zones, web handling, and in-line gauges can work for or against you—often at the same time. The gap isn’t the brochure spec; it’s the control loop and how it holds under real slurry shifts and operator changeovers. Let’s unpack what buyers often miss and how to compare options with clear, testable criteria.

The Hidden Pitfalls When Choosing a Supplier

Many teams start with price, speed, and width. Smart, but incomplete. The right battery coating machine supplier should prove stability under drift, not just quote nameplate numbers. Here is the technical truth: variability creeps in through web tension control, slot-die head alignment, and dryer balance more than through raw line speed. If feedback is slow or noisy, the closed-loop PID chases ghosts. And that means waviness, edge beads, and micro-defects. Look, it’s simpler than you think: ask for evidence of control accuracy over a full shift with slurry viscosity change and foil splice events. If they can’t show an in-spec run tied to inline thickness gauges and downstream calendering data—keep looking.

Where do RFQs go wrong?

Traditional RFQs overvalue max meters per minute and undervalue process windows. They ignore how slot-die trimming responds to anode vs. cathode slurries, how NMP solvent recovery interacts with dryer zones, and how edge bead removal syncs with web guides. Another quiet pain point is metrology: an inline thickness gauge is only as good as its calibration routine and its integration with the coating head. When the loop is tight, you see fewer roll changes and faster golden runs—funny how that works, right? When it’s loose, scrap spikes on Monday mornings. Ask about gravure vs. slot-die changeover time, beta gauge or optical profilometer accuracy, and how the system handles coil set on the current collector. If answers are vague, your risk is not.

From Principles to Practice: What’s Next for Coating Lines

Here’s the forward look. New systems don’t just run faster; they sense and correct before defects spread. A modern china battery coating machine can fuse inline metrology with adaptive controls. That means the slot-die lip gap, pump flow, and web tension are tuned together, not in silos. The principle is simple but powerful: shorten the control loop, and you shrink the defect length. With multi-zone dryer control, heat profiles match solvent load; with air flotation and IR assists, you reduce edge curl and binder migration. Add smarter roll-to-roll choreography—predictive web steering, cleaner splice management—and your process window widens, not narrows, at higher throughput. Semi-formal take: fewer knobs for operators, more embedded logic for stability.

What’s Next

Comparatively, legacy lines rely on operator skill to tame drift. The next wave shifts that burden into software and sensors. Think recipe guardrails, auto-tuning for slurry rheology, and data tags that tie coating to calendering and formation yield. The result is measurable: tighter thickness uniformity, fewer line stops, and better solvent balance through the drying oven—yes, even on wide foil. To choose well, focus on three metrics that cut through the noise. First, closed-loop response time under disturbance (web tension step, viscosity change). Second, sustained Cpk for thickness across a full shift, reported with raw gauge traces. Third, integrated uptime: MTBF for pumps, coat head seals, and dryer fans tied to real maintenance logs. Get those, and you get fewer surprises—and a cleaner path to scale with KATOP.

Introduction — a quick scene, some numbers, and one clear question

Have you noticed a charger that looks healthy but charges like it is holding back? I ask because I saw this at a depot last winter; three identical DC units, one underperforming while the other two hit spec. In the second sentence I want to state the focus plainly: dc ev charger behavior matters to uptime and fleet cost. As someone with over 15 years of hands-on experience in EV charging infrastructure and commercial electrical systems, I often meet this scene — the manager checking voltage, the driver tapping refresh, and the telematics showing lower-than-expected kW (and yes, the data usually tells the story). Here is a simple data point: at a Shenzhen logistics yard in March 2023 we measured a repeated 22% drop in delivered current on the midline charger during afternoon peaks. So why does that happen, and what exactly is failing — the charger, the cable, the grid, or the vehicle? (I will outline practical checks and hard lessons.) Now we move to look deeper at root causes and the common fixes technicians miss.

Part 2 — Deeper layer: traditional solution flaws and the hidden user pain (technical rhythm)

When you trace the problem, you quickly hit software and hardware interaction issues. I will link one broader capability that people mention in meetings: Vehicle-to-Grid — but in many sites the theoretical V2G promise collides with real-world faults. In March 2023, at that Shenzhen site, the nominal 180 kW ABB Terra-style units were paired with older bidirectional inverter controls and legacy power converters. The fleet saw poor handshake between charger and vehicle battery management system; the state-of-charge (SoC) reporting lagged, and chargers derated current to protect the battery. Believe me, the symptom looks like a charger fault but it often is a protocol and SoC mismatch (CAN bus timing, handshake timeout). Edge computing nodes at the site did some local smoothing but were set with long filters, hiding transient spikes that would have triggered proper load-sharing. I trimmed logging and adjusted comms timing; that alone recovered about 12% of lost current in two weeks.

What specific traditional fixes fail?

Many shops still replace hardware first. They order new cables, new breakers, and swap chargers — costly and often unnecessary. Older approaches assume single-point failure; they do not account for dynamic grid constraints, thermal derating in cables, or vehicle-side limits like max charge acceptance or BMS conservatism. From my field notes: replacing a choke coil on 12 April 2023 yielded no change; later tuning the charger’s communication stack did. The hidden user pain is real: drivers get blamed, schedules slip, and the procurement team pays for spare hardware that was never the root cause. I’ll be blunt — diagnostics that ignore SoC profiles, CAN timing, and the charger’s firmware versions waste time and budget.

Part 3 — Forward-looking: principles and case-based outlook (semi-formal)

Building from that diagnosis, the next step is to consider new principles and practical future moves. I want to highlight Vehicle-to-Home as one emerging pattern that changes how we think about power flow: Vehicle-to-Home shifts expectations because it treats the vehicle as a managed energy asset, not just a load. In one pilot in Lisbon (June 2024), using smart metering and an adaptive bidirectional inverter, the house could absorb midday solar and return energy at evening peaks — which also meant the home charger stayed within optimal current windows and avoided derating. The principle is straightforward: manage charge acceptance via coordinated signals (SoC targets, rolling setpoints, and grid-aware schedulers). This requires firmware that supports adaptive setpoints, a charger with robust thermal models, and telemetry that includes battery cell-level alerts. I remember a night test last November when a simple firmware patch improved peak delivery by 9% — small change, measurable result.

What’s Next — short roadmap

Real-world adoption will hinge on three things. First: robust communication standards between BMS and charger — not just CAN, but disciplined timing and version control. Second: site-level energy managers or edge computing nodes that understand short-term grid constraints and can throttle or shift loads. Third: better commissioning checklists — include firmware versions, SoC reporting tests, and cable thermal scans. Small note — real operators will prefer clear pass/fail checks over long reports. To conclude with actionable advice, here are three key evaluation metrics I recommend for choosing and commissioning DC solutions: 1) handshake latency and compatibility score (ms and pass rate), 2) thermal derating margin (percent below rated current at 40°C), and 3) measured charge acceptance recovery after firmware tuning (percentage improvement within 30 days). These metrics are concrete and measurable during acceptance testing.

I write this from direct field experience: installing three 180 kW chargers in Shenzhen (March 2023), tuning comms, and saving the operator roughly 22% in idle charging time and about $12,400 annually in energy and scheduling costs. We cannot ignore simple details like firmware mismatches or SoC reporting cadence. I prefer vendors and integrators who document those tests and who will put the telemetry on the table.

A Technical Reality Check at the Curb

Where does the power really go?

Power paths decide who gets electrons, when, and at what cost. An EV charging supplier promises speed and uptime, but the grid has other plans. Picture a concrete garage at dusk: queues growing, lights flickering, drivers watching range tick down. In some sites, 30% of stalls derate when heat rises; in others, demand charges spike without warning. The weak link is often the power supply for EV charging and how it meets a volatile load. Think power converters, edge computing nodes, and load balancing rules—each one a gatekeeper. If any gate sticks, the night grows longer. Look, it’s simpler than you think: mismatched components plus poor control logic equals wasted capacity.

The hidden pains run quiet, then hit hard. Harmonic distortion creeps in and the transformer hums. Firmware drift breaks OCPP events, so sessions stall and logs go empty (no data, no fixes). Thermal management lags; fans choke on dust; uptime slides under 98% and no one can say why. Meanwhile, a few fast chargers hoard current, starving the rest—funny how that works, right? These are not edge cases. They’re what happens when a site treats power as a static box instead of a living system. So the question is simple and sharp: can your site keep pace when the curve bends? Let’s pull the system apart—and then build it back better.

From Fixed Hardware to Living Systems: Comparative Insights

What’s Next

Old sites lean on fixed rectifiers and one-size cabling. New sites move to modular power stacks, bidirectional inverters, and software-defined routing. The shift is not hype; it’s physics plus control. Silicon carbide stages raise efficiency under partial load; droop control stabilizes feeders; dynamic setpoints spread heat. Add digital twin modeling before the pour, and you see constraints early. Among modern EV charging solution providers, the leaders treat every layer—grid tie, DC bus, charger head, session logic—as tunable. That’s how you stop the cascade before it starts.

Here are the new technology principles in plain terms. First, adaptive orchestration: edge agents near the chargers, with cloud policy only when needed. This cuts latency and keeps power where it belongs. Second, communication that actually sticks: OCPP 2.0.1 with robust retry, plus ISO 15118 for contract handling. Third, grid-smart hardware: power modules with fast fault isolation, N+1 redundancy on the DC bus, and real-time harmonics filters. Add peak shaving with a small BESS, and the same site draws less at the worst hour—and lasts longer. The result feels calm rather than lucky.

Consider a city block retrofit. Yesterday: 150 kW transformer, brownouts, 12-minute average wait. Today: microgrid-ready intertie, V2G-capable inverters, and temperature-aware load sharing. Uptime climbs to 99.95%. Demand charges fall by 28% over a quarter. Mean time to recovery drops under 90 seconds after a fault. Not magic—just better coordination and parts that talk to each other. And when a storm walks in, the site sheds load gracefully, keeping priority bays alive. The lesson travels well to malls, depots, and curbside lanes. Different facades; same spine.

How to Choose: Metrics That Cut Through the Noise

We’ve seen why stalls falter: static designs, blind spots in data, and control loops that lag. We’ve also seen what steadies a site: modular power, fast protection, and orchestration at the edge. The point isn’t to chase every buzzword. It’s to compare suppliers by outcomes that matter in the dark and in the heat. Keep the tone clear, the tests repeatable, and the wiring honest (no hidden derates behind glossy dashboards).

Use three metrics. 1) Resilience under stress: verify N+1 across power stages, MTTR under 5 minutes, and fault localization down to the module. 2) Real-load efficiency: measure system efficiency at 20%, 50%, and 80% load, including harmonics and cooling overhead; track thermal derating onset. 3) Control fidelity and openness: require OCPP 2.0.1 coverage, ISO 15118 support, secure updates (signed firmware, TLS 1.3), and edge failover with local rules. If a supplier can document these with live data—and let you witness a breaker pull test—you’re on solid ground. Quiet systems survive. The rest make excuses.
