Re: DS3 EV - High voltage battery wiring diagram request
I'm afraid we don't have access to the diagrams at the moment but hopefully a member will be able to guide you. It sounds like a possible wiring fault on the ecu's monitor wiring but that is a pure guess!! 
I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!

Actually the EV have 18 Modules, each module has a Electronic board and all of them are connected to the main EV battery ECU in a complex wiring harness, by getting the wiring diagram can be more easily find the defected module or wire .

In the UK cars have a 3 year warranty and the batteries can be even longer (8 years ?). If this applies in your country you should be getting it sorted at a dealer and not having to pay anything.
