We installed two types of “charge station” or more correctly two types of EVSE (Electric Vehicle Supply Equipment) at our home. The first is ClipperCreek’s 40-amp EVSE with J1772 EV charge connector and 23-feet of charge cable. The second is a NEMA 14-50 receptacle on the same 40-amp circuit. The 40-amp circuit is rated to provide 32-amps continuously (40-amps peak) as when charging an EV. So ClipperCreek’s “40-amp EVSE” is limited to 32 amps. (In North America circuits are limited to 80% of their “rated” capacity according to the National Electrical Code. This is to prevent circuits overheating and causing fires.) The NEMA 14-50 receptacle can be used by visitors driving Teslas or for testing mobile charge cables like the Jesla from QuickChargePower.

I’ve included two moble charge cables or EVSEs. The first is a modified version of the trickle charge cable or “granny lead” to some. It was modified to operated at 240-volts. The second is the Jesla High-Power Mobile Charge Cable. In the early days of EV travel in California this high-quality and high-power EVSE was essential for the kinds of trips we took. It’s hardly used now–and that’s the way it should be.
