The EV's power acceptance rate should not be considered when making EVSE purchasing decisions.

• A. True
• B. False
• C. Not sure
• D. Depends on context

Answer: (B)

Charging speed depends on both the vehicle and the charger. The EV's power acceptance rate is the maximum power the vehicle can receive from a charger, determined by its onboard charger and battery management system. When selecting EVSE, you need to consider this rate to ensure you actually utilize the charger’s capabilities. If the EVSE can deliver more power than the vehicle can accept, the charging rate will be limited by the car, so you’re not getting faster charging for that vehicle and you may be paying for unnecessary capacity. Planning with the vehicle’s acceptance in mind also helps you size the electrical service and choose an EVSE that works well with a range of vehicles, or one that can adjust its output for a fleet with mixed needs. In short, the EV’s power acceptance rate is a crucial factor in choosing the right EVSE, making the statement not accurate.
