What Determines the Speed of an EV Charging Session
What Determines the Speed of an EV Charging Session
Charging power changes as the vehicle and station negotiate current and manage battery temperature.
A charger advertises what it can supply, and the vehicle requests power within its own limits. A cold battery, a nearly full battery or a shared cabinet can reduce the rate.
Peak power is usually available for only part of a session. The shape of the charging curve determines how quickly the car adds energy over the stop.
Compare the energy added in a consistent time window and note the starting charge and temperature. Those conditions explain why two stops at the same station may take different amounts of time.
