In short;
- Engine: Warmed up and drive for a bit and bonnet is closed
- Battery: Good condition and charged
- A/C: Is not set to
and blower isn’t on full
In terms of regeneration, this is on overrun/engine braking. Having the clutch in and hitting the brakes will not charge the system.
And the system is designed to run as much of the car as possible off the capacitor, not the battery, this is why it won’t stop/start when the A/C is on demist/full blower.
Finally, manuals are great…
