E torque charging issue

[Ivanpagan2]

While driving I see my battery voltage dropping from 14 now to 13.5 and going to 13.1 not sure if it’s the e torque generator or alternator

It seems that the voltage will fluctuate like that with etorque, which has no traditional alternator. The etorque motor/generator charges the 48v battery module, which in turn charges the 12v main battery. What you’re seeing is apparently normal with etorque. There are other threads here where this is discussed if you care to spend a little time searching for them.

e torque generator or alternator

are you unsure about what to call it?
it's a alternator a generator and a motor. also can be a PIA

It’s staying at 13.1 scanned the vehicle with my scanner and I’m getting nothing im just pretty scared to drive it far or keeping it that way I just got the car not to long ago it was reading 14 volts before but thank you for the info just not sure if I should take it to the dealer not sure if it has warrant to for the e torque systems

Hurricane here. Battery voltage ranges from 12 to almost 15. Auto stop in droops to 12 then during acceleration it’ll rise to 14.7, and cruising it settles to 13.5 ish. Not sure if that relevant or helps.

Even driving it stays at 13.0 13.1
At auto start stop it continues to drop to like 12.4 do u think it’s the 48v hybrid battery in the back

This is at idle

something else to consider. new vehicles have "smart alternators" the charging is controlled by the ecm. yes you guessed it to save fuel, they cycle-drain than charge discharge charge. so there is not a constant load on the motor from it. i'm running a 2000 watt stereo and never look at the voltage.
