Charging Performance

peak kW · 10-80% · curve · cold

In this dataset 800 V-class EVs charge 10-80% in about 19 min, 400 V EVs in about 37 min. The curve matters more than the peak.

Illustrative charging curves from 10% to 80% state of charge. A solid line holds a steady power plateau to mid-pack and then tapers, giving a short stop; a dashed line touches a higher peak early and then drops away, giving a longer stop. The energy added is the area under each curve, so the flat curve delivers more in the same time.

Finding

The charging curve matters more than the peak, and 800 V platforms shorten a typical stop

Leaving out stale rows, the five 800 V-class models in the dataset average about 19 min from 10% to 80% on a capable charger, against about 37 min for 29 400 V models. A car that holds 200 kW to 60% finishes sooner than one that touches 250 kW and drops early, which is why the dataset scores the curve as well as the peak.

Temperature is the other variable. A cold pack that has not been preconditioned charges far slower in the dataset's estimates; cars that warm the battery automatically when navigating to a charger lose much less. New platforms are moving the target: BYD's 1,000 V Super e-Platform in China and the 800 V Neue Klasse, PPE and Mercedes-Benz platforms in Germany push typical stops toward 10-15 minutes. Peak DC and voltage on this page track the current model record, so a newer generation shows its new figures even while its older time estimate is marked stale (11 rows in all).

Background: charging rate, speed and time, connectors and standards and the EV Platform Index.

Data

Charging performance by model

Peak DC and voltage are from the current model record where it has them, otherwise marked estimate; 10-80% time, curve score and cold loss are earlier ElectronsX estimates. Stale rows were estimated for an older specification.

Metrics

What the metrics mean

Charging performance metrics
MetricMeaning
Peak DC (kW)The maker's peak fast-charging power under good conditions; a spike, not an average
VoltagePack architecture class: 400 V, 800 V or higher; higher voltage carries the same power at lower current, with less cable and connector heating
10-80% timePractical session time on a charger that can deliver the car's peak; it captures the whole curve
Curve score A-DA holds high power through most of the session; B tapers earlier; C has a moderate peak or long taper; D peaks low or tapers hard
Cold loss (%)Slowdown when the battery starts cold and has not been preconditioned; it depends on pack temperature, not air temperature
Auto preconditioningWhether the car warms the battery on its own when navigating to a fast charger
