Re: Battery problem update

12 volt battery target SOC is about 80% and the forscan screen shot is for the 12 volt battery.
The 48 volt battery target SOC is about 50% with maximum state of charge about 75%.

Re: Direct Current/Direct Current (DC/DC) Converter Control Module Software Update

Be careful fitting anything other than a standard SLI battery as the charging strategy may not be compatible.

BCM = Body Control Module. Does ignition/key sense and wakes the car from sleep.

Without a 48 volt battery I believe the Vpp is hard to control. So no 48 volt battery and the DC/DC will not charge.

Re: Battery problem update

Interesting you say that chocky. Re the boost, that seems to only kicks in when the electric motor kicks in, kind of like an extricate turbo, I’m not sure how a one litre engine without turbo can produce 155bhp so I believe it is the electric motor that provides the power Out of interest I went bac...

Adding those to the issues I'm having with the flickering of the screen behind the wheel, dead stop/start system (Even when it had been fully charged at the dealership) the seemingly...

Re: Battery problem update

The lithium battery is being used while driving in fact it is key to turning my 1 litre engine into a 155bhp speed machine😂 Nope. The 155ps peak comes completely from the engine. I think I am right in saying that both batteries are charged via the same system Not really. The 48V battery is charged ...
