It's a great concept.
The charger and controller are really both in the exact same place in the circuit with the batteries, so the cabling would be pretty simple.
Do you think there would be any safety issues with power going to the controller while charging? I have a big physical disconnect I unplug while charging/parking/showing off my EV so nobody can accidently turn on the car or make it move.
You only ever use the controller and charger one at a time, and on-board chargers are nicer to be able to pick up a charge when you can out in public.
The whole device would be a little more complicated. The other trouble might be that if your charger breaks, so does your controller! Kinda like the old combination TV/VCRs - I've seen a ton of those thrown out because the one part broke!
