In a bmw 330e which driving mode charges the battery whilst driving best
I would be interested to see typical numbers that support 'the gain in efficiency is larger than the electric losses'I would humbly dispute that.
when charging the battery the engine will be utilised on a more efficient mode than to power the wheels.
Nothing new that some hybrids will use the engine on its most efficient mode to charge the battery and use the motor for wheel power.
The gain in efficiency is larger than the electric losses in the process.
I'm not putting forward any numbers, I'm simply requesting a view of the typical efficiency numbers for the various electrical energy interchanges between the ICE and the electric motor output shaft, that support your statement...Without going technical,
an engine is 20 to 25% efficient. (when powering wheels)
Are you saying that you will have 75% losses in heating and friction on an electric motor?
