Your whole response here is extremely snarky and wildly untrue. If wiring up an EV is “quite basic” I’d really love to see the results of your DIY EV.

I’m sure everything from charge control, to battery wear distribution, to temperature regulation, to range estimation, to powering the various car subsystems, to braking regeneration, to safety systems comes naturally to you, but please, for the rest of us simpletons, do us a favor and publish an “EV Engineering For Dummies” book! I’ll buy a copy!
