Re: EVSE 120 VAC Charging Efficiency

Thanks. I knew the charger was onboard in the car and I caught my error after reading many more posts. I have a lease pending and I wanted to make sure I made a reasonable estimate of how much of my home PV solar system output would be consumed by the car considering my usage was approximately 30 mi...

Re: EVSE 120 VAC Charging Efficiency

Thanks for pointing out that site. It looks like the 120 VAC EVSE at 12 amps will be 75% efficient. I was using 85% so I will revise my numbers.

Re: L1 and L2 Charging Efficiency

Thanks. Kevin. That is exactly what I was looking for and it is consistent with a value of 84% for L2 charging of a Nissan Leaf. I wonder if any other Spark EV owners have a value for L1 charging? The value I found for the Leaf is 73%.

L1 and L2 Charging Efficiency

I have been trying to find out what the L1 and L2 charging efficiency ratings are for the Chevy Spark EV. Do any of you owners have that information? Chevy and my local dealer were not of any help.

Thanks.

Dennis
