Vehicle charging profiles
Check the battery version and charge window, and understand the conditions behind published figures.
View vehiclesIndependent EV charging guide
Understand fast charging. Find what works for your journey.
How fast a car charges depends on the vehicle, the battery’s state and the charging site, all taken together. FlashCharge.ai helps you understand charging figures, compare options and confirm the conditions you need before you set off. Start with a vehicle, or begin with a beginner’s guide.

Vehicle charging profiles: check the version, then the performance
A model name alone is not enough to define charging capability. Different sales markets, model years and battery versions may use different connectors and charging configurations. Before comparing, confirm the exact version you plan to buy or already drive, then read the matching information.
Find the right charging information for your exact EV. Check the market, model year and battery version before comparing charging claims. A charger rating describes the equipment; it does not guarantee that your vehicle will accept that power throughout a session.
How to read a vehicle card
The start and end charge should always be shown with the time. A 10%–80% figure cannot be compared directly with 10%–97%, and a vehicle’s peak cannot be judged from the charger’s rated power alone. Where a source does not state the temperature, preconditioning status or exact model year, keep it marked as “not disclosed” rather than filling in conditions on the source’s behalf.
General charging conditions: see sources S1, S2.

Example record
Hyundai IONIQ 5
Manufacturer claimNot a FlashCharge.ai test
Hyundai’s European website describes the 84 kWh Long Range version: at a 350 kW DC station, 10%–80% takes about 18 minutes; at a 50 kW DC station, the same window takes about 76 minutes. The 350 kW here is a station condition and should not be written as the vehicle accepting 350 kW throughout. The page’s summary does not give a complete record of test temperature or preconditioning. [S3]

Manufacturer claimDifferent market and configuration
Hyundai’s US website, describing the 2027 IONIQ 5, lists about 20 minutes for 10%–80% using the included CCS adapter on 350 kW, 800V DC equipment. The two official figures should not be read as contradictory test results for the same version; first of all, they remind us that a vehicle profile must state the market and configuration. [S4]
350 kW, 800V DC with CCS adapter≈ 20 min10% → 80%
This page shows published information and its scope; it does not choose a “world’s fastest car”. To compare two vehicles, first align the charge window, then look at usable battery capacity, energy added and the real test conditions. For energy differences within the same window, see the teaching example in Tests.
Learn · Charging basics
Power tells you the speed. Energy tells you how much you added.
kW is a unit of power: how quickly energy is transferred. kWh is a unit of energy: how much a battery stores or a session adds. Understanding these two units stops you from reading “high-power charger” as “any car will fill up quickly”.
If the average power is 100 kW, half an hour corresponds to about 50 kWh of energy. You must use the average power over that half hour; the highest number you see at the start only describes that moment. As the vehicle’s charge level, temperature and equipment conditions change, power may change too. [S1]
AC charging and DC fast charging
With AC charging, the vehicle’s on-board charger converts AC into the DC the battery needs; with DC fast charging, the conversion happens mainly at the station. Each suits a different length of stay. Choose by real need at home, at work and at long-distance rest stops — there is no need to chase maximum power for every charge. [S1, S2]
Try it: power × time = energy
Teaching example
Energy transferred
≈ 50 kWh
Before additional losses are considered
kW measures power. kWh measures energy. A charging session averaging 100 kW for half an hour transfers about 50 kWh before additional losses are considered. Use average power over the interval, not a brief peak, when estimating time. Your vehicle, its battery condition and the charging equipment all influence the result.
Learn · Charging curve
How to read a charging curve: the whole window matters more than the highest number
A charging curve shows charging power at different charge levels. Two vehicles with similar peak power may behave differently across the window you actually use. A fuller record also includes time and energy added, so it can explain how much a stop really achieved.
As the battery approaches full, the charging system usually lowers power. Charging to 100% often takes considerably longer than charging to 80%. Whether to keep charging on a long trip depends on the next leg and the charge you want on arrival; set everyday charging targets according to your vehicle manual. [S5]
A peak is a moment. A charging session is a process. Look for the full interval, its elapsed time and the energy delivered. Power often falls as the battery approaches full charge. The illustrative curves on this page explain the idea; they are not measurements of production vehicles.
Common questions, short answers
Is 800V always faster?
It describes part of the electrical architecture. Vehicle acceptance and equipment compatibility also matter.
Why can charging be slower in the cold?
Battery temperature affects charging conditions. Follow your vehicle’s instructions for preconditioning features and how to use them.
Does a high-power charger force its full rating into the car?
No. Charging is negotiated between the vehicle and the equipment, and real output is limited by both sides and on-site conditions.
Is charging below the advertised power a fault?
Not necessarily. Check the charge level, temperature, equipment and test conditions before concluding something is wrong.

Technology
How a fast-charging technology becomes a usable experience
The high power in a headline comes from a whole system: the site needs available supply and output capability, connectors and cables must support the conditions, and the vehicle negotiates charging based on charge level, temperature and its own limits. To judge a technical advance, ask how it works, what it requires and where you can use it.
One set of questions for every brand
Each guide covers: what the technology is, which vehicles it applies to, equipment requirements, published data, real-world availability, and what has not yet been verified. Manufacturer statements on lifespan or performance are labelled as manufacturer claims; without like-for-like comparisons, we do not assert how far ahead something is or that it will never harm the battery.
Explore the system behind the headline. Our technology guides explain how vehicles, batteries, connectors and charging sites work together. Each guide separates published claims from verified observations and identifies the conditions required to use the technology.
| Topic | Questions it should answer |
|---|---|
| High-voltage architecture | How voltage relates to current and power, and what the vehicle and station need |
| Battery and thermal management | Why charge level and temperature affect charging performance |
| On-site storage | How it buffers short-term supply demand, and the limits of sustained service |
| Connectors and communication | How the mechanical interface, electrical parameters, communication and access together decide compatibility |

Reading a flash-charging claim
How to read the BYD Flash Charging figures
Manufacturer claim
BYD’s official announcement in March 2026 states that, under its published conditions, the matching system can charge 10%–70% in about 5 minutes and 10%–97% in about 9 minutes, and introduces charging equipment of up to 1,500 kW. Equipment ratings and battery charging times should be recorded separately; an equipment rating should not be treated as every vehicle’s sustained acceptance power. [S7]

Deployment
Separate announced plans from operating sites, and verify the vehicles and sites market by market.
What you actually need to check
If you are considering this technology outside China, first check whether the locally sold vehicle supports the feature, whether nearby equipment is open, and whether using the site has vehicle or account restrictions. Results from a launch event cannot replace the information for the local vehicle you plan to buy.
Publishing rules for similar guides
We cover BYD with the same method we use for other manufacturers and charging operators. Manufacturer claims, independent tests and our own calculations are labelled separately; technology guides link to vehicle profiles and regional network guides so readers can keep checking availability.
BYD Flash Charging explained. BYD’s March 2026 announcement reports approximately five minutes from 10% to 70% and nine minutes from 10% to 97% under its published conditions. These are manufacturer-reported figures. Check the exact vehicle, charger and market before applying them to a journey. Equipment output ratings do not establish sustained vehicle charging power.
Networks
Finding a site is the start. Starting a charge smoothly is the goal.
A charging icon on your route is only where the search begins. Before you leave, check the specific connector, vehicle access, opening hours, start method and fees. For a network you have never used, set up your account and payment in advance and keep an alternative site ready to make the trip more predictable.
Pre-trip checklist
Tick each item as you confirm it with the operator.
0 of 5
Ready to go. Keep your alternative stop in the plan.
Check access before you travel. A station listing does not guarantee that a connector is available, working or approved for your vehicle. Confirm compatibility, opening hours, payment and current conditions with the operator. Keep an alternative charging stop in your plan.
Where no live data is available, pages state clearly: “Site information only — does not represent live availability.” Site names, addresses and opening details all show their source and last checked time. Public charging preparation: S2.
Network guide example
How drivers of other EV brands check Tesla Supercharger access
Tesla’s support page explains that sites available to other brands should be checked in its app or official map; if a site does not appear in the list available to other brands, you cannot assume you can charge there. Whether a specific model, connector or adapter is supported must also be confirmed with local guidance. [S5]
- Select your country and vehicle.
- Open the site details page.
- Confirm the equipment type, adapter requirements and start method.
- Check the displayed price and any additional fees.
We explain the steps to check, but we do not promise current access based on an old screenshot.
Tesla Supercharging access. Use Tesla’s local app or official map to identify sites open to your vehicle. Check the site details and any adapter requirements before departure. FlashCharge.ai explains how to verify access; it does not replace the operator’s current information.
How regional guides are organised
| Section | What it shows |
|---|---|
| Region and scope | Country or city, and which operators are covered |
| Operator links | Official maps, support pages and payment information |
| Compatibility | Separates connector match, vehicle access and adapter support |
| Status record | Records planned, under construction and operating separately, with evidence dates |
| Practical notes | Car park location, opening hours and on-site additional fees |
Using open station data
Open Charge Map provides station information and a developer API, and is a candidate data source for a future site directory. Before integrating, check each record’s source, licence, attribution requirements, API rules and regional coverage; an open directory cannot be repackaged as guaranteed live fault or availability information. [S8]
Tests and cases
Make every charging record verifiable
A screenshot of high power cannot represent complete charging performance. A useful record states which vehicle was tested, the starting charge, the equipment used and whether the session was interrupted. If the full raw record is not available, treat it as an observation and clearly list what is missing.
Our test
Third-party test review
Teaching example
| Stage | What to keep |
|---|---|
| Before | Model year, market, battery version, odometer, software, ambient temperature, battery temperature where available, preconditioning and starting charge |
| During | Time, charge level, power and cumulative energy where available; site, equipment, power sharing and interruptions |
| After | End charge, total time, where energy was metered, cost, raw record link and missing data |
The full window time and the raw record appear on the same page. If data comes from another tester, we credit the author and state how it is licensed; a publicly viewable video is not material that can be republished freely. When we have not run a test ourselves, the page says “Currently featuring reviews of public information” and only shows content with a real source.
A useful test shows its conditions. We look for the exact vehicle, starting charge, battery preparation, charger and complete session record. Missing conditions remain visible. A third-party report is credited to its author; a teaching example is never presented as a road test.
Original teaching case
Same time, different energy added
The two vehicles below are fictional teaching subjects using a simplified linear energy model. Both charge from 10% to 80% in 20 minutes, but their usable battery capacities differ, so the energy added differs. This example explains a comparison method; it does not correspond to any brand and is not a vehicle ranking.
Energy added to the battery, in kWh. Fictional teaching vehicles.
| Item | Teaching vehicle A | Teaching vehicle B |
|---|---|---|
| Assumed usable capacity | 60 kWh | 90 kWh |
| Charge change | 10% to 80% | 10% to 80% |
| Assumed energy added | 42 kWh | 63 kWh |
| Charging time | 20 minutes | 20 minutes |
| Average power on this basis | 126 kW | 189 kW |
Calculation: 60 × 70% = 42 kWh, and 42 ÷ (20 ÷ 60) = 126 kW; the other vehicle gives 63 kWh and 189 kW in the same way. A real vehicle’s displayed charge is not guaranteed to be strictly linear; a rigorous analysis should prioritise verifiable energy records and explain the metering basis.
Range added also needs a consumption assumption
Assuming both vehicles use the same 18 kWh/100 km, purely as a maths demonstration, 42 kWh and 63 kWh correspond to about 233 km and 350 km. Real motorway, winter or city consumption differs; you cannot mix range gains from different test cycles and then claim one car is faster.
Teaching example, not vehicle test data. Two hypothetical EVs both charge from 10% to 80% in 20 minutes. With assumed usable capacities of 60 and 90 kWh, the simplified energy gains are 42 and 63 kWh. Equal charging times do not necessarily mean equal energy gains or equal distance added.
How to use this method: first decide whether you care about stop time, energy added or distance you can drive, then choose a consistent basis for comparison. Buying decisions should also consider your usual routes, available networks and cost; a single test result cannot cover every situation.
Tools
Estimate the energy you need, then the time and the cost
The value of a charging tool is making its assumptions visible. Enter usable battery capacity, start and target charge and an estimated average power to get a rough time. When there is no reliable basis for average power, show results for several assumptions instead of an overly precise promise.
A Q&A assistant built on sourced information
A planned assistant will answer questions such as “Explain this vehicle’s charging conditions” or “Can these two published figures be compared?”. Answers will show the vehicle version, data date, original link and missing items. Without live site data, the assistant directs users to the operator and never answers “this site is definitely free right now”. It will launch once the source library has grown.
When data is insufficient, tools say: “Current information is not enough to give a reliable prediction for this vehicle in this window; you can run a scenario with custom parameters.”
About
About this site and our method
Why we built FlashCharge.ai
Fast-charging information is scattered across product pages, technical launches, site notices and test videos. FlashCharge.ai organises it into guides that are easier to search, helping readers check how a charging claim relates to a specific vehicle, piece of equipment and region. Our content is edited independently and we are not affiliated with the manufacturers or operators we cover.
How we present evidence
Manufacturer data describes the performance a brand publicly claims and is not automatically independent verification. Third-party tests describe observations under specific conditions and do not automatically represent all vehicles. Our calculations and teaching examples show their assumptions and formulas and are never published as product tests. Conclusions with missing or unverifiable sources are left out of comparisons.
Corrections and commercial relationships
If you find an error, report it with the original link, vehicle version and where the issue appears. Significant revisions show the update date and a note of what changed. Any sponsorship, promotion or commission is disclosed next to the relevant content; paid partnerships do not change how data is presented or hide missing conditions.
