Charging Specs for Every Popular EV: Battery, Onboard Charger & DC Power Compared
A complete guide to the EV charging specs that actually matter: battery capacity, onboard charger power, and DC fast-charging rates for the most popular electric cars in Europe.

When comparing electric vehicles, three charging specifications determine how fast you can recharge: usable battery capacity, onboard charger power, and maximum DC charging power. Usable capacity (measured in kWh) is the energy your car can actually draw on -- it is always lower than the gross capacity because manufacturers reserve a buffer to protect battery longevity. For example, the Tesla Model Y Long Range has a gross capacity of roughly 78.1 kWh but only 75 kWh is usable.
Charging Specs for Every Popular EV: Battery, Onboard Charger & DC Power Compared
Onboard charger power (measured in kW) caps how fast the car can accept AC electricity from a home wallbox or public AC station. Most EVs ship with an 11 kW three-phase charger, but some entry-level trims still come with 7.4 kW single-phase units. This number is irrelevant at DC fast chargers, where the station converts AC to DC externally.
Maximum DC charging power is the headline figure -- the peak kilowatt rate the car can accept from a CCS or CHAdeMO fast charger. A higher peak sounds impressive, but sustained power across the 10-80 % SOC window matters far more for real-world road-trip stops. Always look at the full DC charging curve, not just the peak number.
How to Read an EV Spec Sheet
EV spec sheets can be confusing because manufacturers mix gross and usable battery figures, quote peak DC power that lasts only a few seconds, and list AC charging rates that assume a three-phase supply you may not have at home. Start by identifying the usable battery capacity -- this is the number that determines your real range and your real charging time. If the spec sheet only shows gross capacity, subtract roughly 5-8 % for the buffer.
Next, check the onboard charger rating and whether it is single-phase or three-phase. In countries where most homes have single-phase supply (UK, parts of France), an 11 kW three-phase charger will only pull about 7.4 kW at home. In Germany or Belgium, where three-phase is standard, you will get the full 11 kW or even 22 kW if the car supports it.
Finally, look at the DC fast-charging column. The spec sheet should list peak DC power (e.g., 170 kW) and ideally the time for a 10-80 % charge. If the 10-80 % time seems long relative to the peak power, the car's charging curve likely tapers early. A car rated at 170 kW peak that does 10-80 % in 30 minutes is sustaining power much better than one that takes 40 minutes with the same peak.
Quick Comparison of Popular EV Models
Here is how some of Europe's best-selling EVs stack up on key charging specs. The Tesla Model Y Long Range offers 75 kWh usable, an 11 kW onboard charger, and up to 250 kW DC peak -- it charges from 10-80 % in about 27 minutes under ideal conditions. The Renault Scenic E-Tech Long Range packs 87 kWh usable with an 11 kW (optional 22 kW) onboard charger and peaks at 150 kW DC, delivering 10-80 % in roughly 37 minutes.
The Peugeot e-208 (54 kWh usable, 11 kW AC, 100 kW DC peak) is a compact city car that takes around 25 minutes for 10-80 % thanks to its smaller battery. The Volkswagen ID.3 Pro S with its 77 kWh usable battery, 11 kW AC charger, and 170 kW DC peak manages 10-80 % in about 29 minutes. The Hyundai Ioniq 5 stands out with up to 239 kW DC peak on its 77.4 kWh battery, achieving 10-80 % in just 18 minutes thanks to its 800 V architecture.
Notice that peak DC power alone does not tell the full story. The Ioniq 5's flat charging curve means it sustains high power far longer than competitors with similar peak numbers. When choosing an EV, always compare the 10-80 % time alongside peak power to get the real picture.
Using Plan EV Charge to Compare Models Side by Side
Plan EV Charge lets you simulate real charging sessions for any popular EV model using manufacturer-verified battery specs and DC charging curves. Select a car from the dropdown, pick a charger type (home outlet, wallbox, or fast charger), set your start and target SOC, and instantly see the estimated time, energy delivered, and cost. Then switch to a different car and compare the results.
This is especially useful when cross-shopping vehicles. For example, you can simulate a 10-80 % DC fast charge for both the VW ID.3 and the Tesla Model Y on the same 150 kW charger and see exactly how the different charging curves translate into minutes spent at the station. You can also compare home charging scenarios -- plug a Renault Scenic with a 22 kW onboard charger into an 11 kW wallbox versus a Peugeot e-208 with the same wallbox and see how battery size and onboard charger ratings affect overnight charging.
The calculator accounts for real-world efficiency losses (8 % for AC, 5 % for DC) and uses the actual DC charging curve data for each vehicle, so the results closely match what you will experience in practice. Try it now to find the EV that best fits your charging routine.
