2018 Bolt EV Premier Nightfall Gray
GM charges $525 for the stock 120V EVSE. If they did an OEM contract with Mustart to supply the Travelmaster as a stock cord, and offered the various adapters as optional items, surely they could source it for close to what they pay Clipper Creek for the current cord. Include the 5-15 plug and cord, then everything else optional.It still points out how expensive ($370) these EVSEs are being sold relative to their component cost. The guts of an EVSE is little more than a small power supply, a $8 contactor, and a control board that's the equivalent to a $10 Arduino clone, along with some relatively simple support hardware for ground fault detection, contactor binding detection, and the like. The J1772 cord itself really costs more than triple of everything else.
But why should OEMs get away with offering limited EVSEs with EVs? Imagine if one had to buy an aftermarket device in order to fill a gas tank at its maximum rate. Folks would flip out over the idea.
