5%? That is one kWh and would require a 80 Ah battery.

I.e. power steering runs on the 12 volt bus, so you either need to make sure that either:

  • critical systems like these run off the inverter (negating your 5%),
  • be damned sure your 12 volt battery is capable of supporting you on even the longest drive (including fans, lights),
  • start charging anyway when the voltage drops below a certain threshold.

I don’t know which cable comes from the inverter.

I would connect it only when charging main battery,and thus extend range by 5 % by my calculations.

Good info 🙂

The standard maintenance scheme is to replace the battery every 3 years. I think I will have it tested and then decide. After all it is my car and my battery. If it is iffy I will not hesitate to replace it immediately with dropping temperatures.

I try to disconnect the battery and everithing works fine without the 12 V battery.I can drive around wirhout 12 V Battery.
And yes you can jumpstart a zoe even without the 12 V battery installed.
everithing works until the main 400 V contactor switches off.(didn’t try ABS)
I have R240,dont know about q210.

This is a least what my dealer told me! Mine has thus been replaced on Friday, but of course in insisted on getting the old one 😉
