Which of the following is not a variable that determines the charging time of an EV?

The connector configuration is not a variable that directly influences the charging time of an electric vehicle (EV). While different connector types might support varying levels of power delivery, the actual time taken to charge an EV depends more significantly on the power capacity of the electric vehicle supply equipment (EVSE) and the electrical service available to the EVSE.

The max power capacity of the EVSE’s converter is essential because it establishes the maximum amount of electrical power that can be delivered to the vehicle during charging. A higher capacity typically means faster charging times, assuming the EV itself can accept that rate of power.

The size of the electrical feeder or service supplying the EVSE also plays a crucial role. It must be sufficient to handle the power requirements needed by the EVSE; otherwise, charging could be limited by the capacity of the feeder, resulting in longer charge times.

Understanding these factors is vital when evaluating how quickly an EV can be charged, while the connector configuration primarily concerns compatibility between the EV and the charging station rather than the actual speed of charging.
