MANUFACTURER CLAIMS · AUDIT THE WINDOW

Peak kW is not
a charging curve.

Charging claims only compare cleanly when the battery, percentage window, temperature and test conditions match. This table keeps the advertised window beside the headline number.

Peak power

The highest instantaneous rate the car may reach. It says nothing about how long that rate is sustained.

Charge-window time

A more useful claim, but 10–80% and 30–80% are not equivalent tests.

How to read a charging claim

Match the window

Adding the first 20% can materially change an advertised time. Compare 10–80 with 10–80.

Check the charger

A car cannot receive 230 kW from a charger that can only supply 150 kW.

Expect tapering

Power normally falls as charge rises. A peak number should never be used to calculate the full session.

Cold batteries, shared charger output, battery preconditioning and station voltage can all affect a real stop. For home AC sessions use the dedicated time calculator instead of any DC peak figure.
