Basics

An EV charging rate can fall when another car connects nearby without either vehicle developing a fault.

An EV can travel fewer miles per kilowatt-hour on a fast highway trip than on a moderate-speed route.

Regenerative braking recovers some energy that would otherwise become heat during slowing.

An EV charging adapter that physically fits is not automatically suitable for the vehicle, station, or charging mode.

An 11kW charging point cannot make every electric car charge at 11kW.

The fastest number advertised for an EV is usually a peak charging capability, not a constant rate from empty to full.

The electricity meter can record more energy than the EV battery appears to gain.

Level 1 charging is slow compared with a dedicated higher-power setup, but slow does not automatically mean useless.

A higher-power EV charging installation can shorten some sessions, but only if the vehicle and site can use it.

A powerful charging station cannot make a cold EV battery accept unlimited power.
