Outside of the car, will this allow residential EVSEs (the ‘charger’ on the side of your house/garage) to become a lot smaller?

- formerly_proven 5y agoThere's no power conversion in an EVSE, it's just an RCD and a contactor.
- dreamcompiler 5y agoWhy do they need to be smaller? The Tesla EVSE is about the size of a loaf of bread. And I doubt it needs SiC because it's just a smart relay for 240v anyway; it's not switching power at high frequencies or getting hot.
- rusanu 5y agoA quick intro into EVSE and why there is no power 'charger' in them, and the space they take is just empty air https://www.youtube.com/watch?v=RMxB7zA-e4Y https://www.youtube.com/watch?v=RMxB7zA-e4Y
- unraveller 5y agoTL;DW the equipment is empty as it is just like a fancy light switch, an ardiuno hack could replace it, it's all the car's job to negotiate the power it needs. The cost is in the installation.
- viernullvier 5y agoAs others said, conventional EVSEs are just spiced-up power switches, so there's not much to gain from SiC. It does however open up a pathway to smaller / cheaper / more efficient residential DC fast chargers which can also enable a widespread rollout of V2G.
