ClipperCreek LCS-20

ClipperCreek, a California-based EVSE manufacturer, recently released on its blog a very informative table comparing charging time depending on electric car and EVSE output.

Charging time depends on the power of the on-board charger (maximum AC power that a car can handle) and the power output of the EVSE (maximum AC power that can be supplied to the car).

In the beginning, cars like the Nissan LEAF were equipped with 3.3 kW on-board chargers and could charge in less than 8 hours at best (we are talking only AC charging). Now, more and more cars are equipped with 6.6 kW chargers (at least as an option), which are able to accept up to 19.2 kW in the US.

If you considering an electric car, it would be good to match EVSE power with on-board charger power level to get the lowest charging time. For most models, 7.7 kW seems to be enough to minimize charging time (in that case, ClipperCreek HCS-40 would be a wise choice).

Then there's the Tesla Model S, which is better matched to the ClipperCreek HCS-60.
