Wondering if this is normal, to only pull 6.0 to 6.1 Kwh vs. the 6.6 Kwh available.
An EV's charger does control the current by telling the EVSE what current to deliver. As a battery pack nears a full charge, the charger will tell the EVSE to reduce the current and thus the charging power.
I typically charge from near empty and the charge maxes out at 6.1kW where the Chargepoint EVSE indicates it's capable of doing 6.6kW. Was wondering why this discrepancy existed,
I was careless and incorrect with my description. Thanks for this clarification!eNate said:The car doesn't (can't) tell the EVSE what current to deliver, and the EVSE doesn't have the ability to regulate current.
The communication on the J-1772 protocol is the EVSE indicates the available current to the vehicle. It is then up to the car (charger) to use up to that amount of current, and if the charge conditions call for less than what's available, the car doesn't communicate this to the EVSE, it just uses less.
