I noticed when DC charging recently (on first proper long journey), that the charger knows (it displays it) what percentage the battery is.
Clearly it is something that is and can be communicated via the type 2 cable.
So, why don't our installed home "chargers" read it and are able to manage the charge percentage?
- I have the Ohme charger which has no idea what percentage the battery is at, I am assuming from what I've read that none of the others do either?
Obviously, a DC charger, is kinda managing the charge to a certain extent as it is doing the actual AC-DC conversion. But in terms of the plug/connection it has to the car, it uses the same connector/pins as when charging AC - yes it has the 2 additional pins but they're purely for putting the DC power through not for communication.
Am I missing something obvious here.
I cannot think of any reason why when charging using our home AC devices, they too should not be able to read the cars battery percentage and therefore should have the facility to be allow the user to specify charging schedules/logic based on the actual battery percentage.
