The typical EV battery in the evstats.org catalog is 74.4 kWh (median). The mean is 71.5 kWh. Snapshot 10 September 2026: 1,372 available rows, each with one battery field. That field is the catalog kWh, not a sales-weighted market average, and it is not split into usable versus gross.
Kilowatt-hours measure stored energy. They are not range and they are not power. Power is kW; the pair is unpacked in kW vs kWh. This page is the size of the tank across the file.

What EV battery capacity means
EV battery capacity is the energy the pack can store, written in kilowatt-hours (kWh). One kilowatt-hour is one kilowatt delivered for one hour. EIA defines it that way. NIST conversion tables set 1 kWh = 3.6 MJ exactly.
On a spec sheet the battery cell is the tank. The motor peak is kW. The DC stall ceiling is also kW. Efficiency is Wh/km on the WLTP cycle. Mixing those four is how a buyer reads “80 kWh” as “this car is faster” or “this car always goes 500 km.”
The unit on the charging receipt is also kWh. NIST Handbook 130 (2026) sells retail EV fuel in kilowatt-hours, not minutes. The stall’s posted rate is kilowatts. Same split as home AC: an 11 kW wallbox is the rate; overnight you might add 40 kWh.
Average vs typical in this file
People type “average EV battery capacity” and “typical EV battery size” as if those were the same sentence. In this extract they are not.
| Statistic | Available rows (n=1,372) |
|---|---|
| Mean | 71.5 kWh |
| Median (typical) | 74.4 kWh |
| 25th percentile | 58 kWh |
| 75th percentile | 86 kWh |
| Minimum | 14.5 kWh |
| Maximum | 123 kWh |
The mean sits below the median because a long tail of small hatchbacks and city cars pulls the average down. Half the available rows are at 74.4 kWh or more. A row near that median is the MG MG4 Electric 77 kWh (MY23–25) at 74.4 kWh and 425 km WLTP, or the Smart #5 Pro (MY25) at 74.4 kWh and 370 km WLTP. Same tank. Different cars.
Two discontinued rows sit outside this table. They do not move the median. They do change the all-row maximum to 141 kWh. The homepage’s “average battery” line uses every row and rounds to one decimal; that is why it can print 71.6 kWh next to this page’s 71.5 kWh on available rows.
How the packs are spread
Most of the file is not a 30 kWh city car and not a 120 kWh flagship. It is the middle.
| Pack band | Available rows | Share |
|---|---|---|
| Under 40 kWh | 98 | 7.1% |
| 40–59.9 kWh | 290 | 21.1% |
| 60–79.9 kWh | 511 | 37.2% |
| 80–99.9 kWh | 377 | 27.5% |
| 100 kWh and up | 96 | 7.0% |
Sixty to eighty kilowatt-hours is the modal band: 511 of 1,372 available rows. Add the 80–100 band and you have about two thirds of the catalog. Under 40 kWh is a small, old, or city-car slice. Over 100 kWh is still a minority.
Capacity by body type
Body type is a better first cut than “average EV” as a single species.
| Body | n | Mean | Median | Min | Max |
|---|---|---|---|---|---|
| SUV | 676 | 75.3 kWh | 77 kWh | 27 kWh | 123 kWh |
| Sedan | 288 | 84.2 kWh | 83.7 kWh | 28 kWh | 122 kWh |
| Hatchback | 189 | 45.0 kWh | 46.3 kWh | 14.5 kWh | 79 kWh |
| Van | 146 | 60.6 kWh | 63.8 kWh | 20.5 kWh | 115 kWh |
| Wagon | 61 | 81.1 kWh | 83.7 kWh | 46 kWh | 97 kWh |
| Convertible | 9 | 41.0 kWh | 28.9 kWh | 16.7 kWh | 83 kWh |
| Coupe | 3 | 99.1 kWh | 102 kWh | 83 kWh | 112.4 kWh |
SUVs are half the available file (676 rows) and sit near the catalog median. Hatchbacks sit about 30 kWh lower. Sedans sit higher because this catalog’s sedan slice includes long-range cars, not a US compact-sedan majority. Convertible and coupe counts are too small to treat as a market. The catalog is the sortable version of the same cells.
Smallest and largest rows
The floor on available rows is 14.5 kWh: Citroën C-Zero, Peugeot iOn, and Mitsubishi i-MiEV. Those are the same PSA/Mitsubishi city-car family. They are still marked available in the file. They are not a 2026 family SUV.
A current small pack in the same file is the Dacia Spring Electric 45 at 25 kWh. That is the other end of “do I need 75 kWh for a town loop.”
The largest available row is the Lucid Gravity Grand Touring (MY26) at 123 kWh. Several Mercedes-Benz EQS (MY26) rows sit at 122 kWh. This is not a US full-size pickup catalog. A 200 kWh Cadillac does not appear here, so the maximum is not a global ceiling.
The Car statistics page ranks the same battery column as “Largest Battery.”
Sales-weighted averages are a different number
IEA’s Global EV Outlook 2026 reports 2025 sales-weighted battery sizes for battery-electric cars: close to 70 kWh in the European Union, below 60 kWh in China, and about 90 kWh in the United States (IEA, Electric vehicle batteries chapter). Those figures weight each model by how many were sold. A high-volume 55 kWh hatch in China pulls that average down. A high-volume US SUV pulls that average up.
This page weights each catalog row once. A rare 122 kWh EQS counts the same as a common 77 kWh ID.4. The 71.5 kWh mean landing near IEA’s EU figure is a coincidence of mix, not a proof that we measured the same thing. We also store WLTP range and euro catalog prices, so the file leans European. Do not paste 71.5 kWh into a sentence about “the average new EV sold in the United States.”
IEA also notes LFP chemistry took over 55% of EV batteries deployed in 2025. Chemistry is a different field. What is LFP is that page.
Usable vs gross
Gross capacity is the energy the pack can hold on paper. Usable capacity is the share the car will let you discharge in normal driving. Makers leave a buffer so the cells spend less time at the top and bottom of the window. Charged EVs walks through that protection layer as a longevity and thermal choice, not as a trick.
This file stores one number. Some source sheets publish usable. Some publish gross. Some publish a rounded brochure figure. We do not split them. Treat 74.4 kWh as “the number in the row,” not as EPA usable battery energy and not as a lab full-cycle measurement.
If two cars advertise 77 kWh and one of them is 82 kWh gross / 77 kWh usable, the trip planner should use 77. The comparison tool puts the catalog cell on both sides. It cannot invent the missing buffer.
Capacity is not range
Range is usable energy divided by consumption, then distorted by speed, heat, and payload. The same 74.4 kWh pack is 425 km WLTP on that MG4 row and 370 km on that Smart #5 row. The tank matched. The Wh/km did not.
Highway and winter cut the laboratory number further. EV range in cold weather is the climate page. The longest-range leaderboard sorts WLTP distance, not kWh. A smaller, efficient pack can out-range a larger, heavier one. That is why the battery column and the range column are separate.
EPA stickers add another translation: MPGe and kWh/100 mi, including charging losses. What is MPGe is that label. This catalog does not store EPA pack energy.
How to use the number
If you charge at home and your day is short, a hatchback-sized pack (this file’s hatch median is 46.3 kWh) is often enough. The Dacia Spring row is the extreme of that argument. You are trading reserve, winter margin, and highway stops for mass and price.
If the car has to do mixed weeks and the odd motorway, the modal 60–80 kWh band is where most of this catalog already sits. That is also where the median 74.4 kWh lives.
If the job is repeated long highway days, pack size is only half the sheet. Peak DC and the 10–80 curve decide the stop. The fastest-charging board and the charging simulator are the other half. A 123 kWh Lucid that tapers still needs a stall plan.
Age shrinks the tank. Battery lifespan is the wear page. Do not plan a commute that only works on day-one kWh.

Source: evstats.org cars extract, 10 September 2026. Filter: is_available is true and battery_kwh is a positive number. Count: 1,372 of 1,374 rows. Two rows fail the available filter and are excluded from the tables above. Statistics are the arithmetic mean, median, and percentiles of that one field. Body-type splits use the file’s body_type string. No sales volumes. No usable/gross split. No EPA conversion.

Quick answers
What is the average EV battery capacity? In this catalog on 10 September 2026 the available-row mean is 71.5 kWh. The median, which is the better “typical” figure, is 74.4 kWh (n=1,372).
What is a typical EV battery size? Typical here means the median: 74.4 kWh. Most available rows sit between 60 and 100 kWh. Hatchbacks cluster near 46 kWh. SUVs cluster near 77 kWh.
Is EV battery capacity measured in kWh? Yes. Capacity is energy, so the unit is the kilowatt-hour. Charge rate is kilowatts. Do not write kW/h.
What is usable vs gross battery capacity? Gross is the pack’s full store. Usable is what the car will let you use. This file keeps one number and does not label which one the maker published.
Does a bigger battery always mean more range? No. Range also depends on Wh/km, speed, weather, and payload. Two 74.4 kWh rows in this file differ by 55 km WLTP.
