Alternatively, just don't connect the onboard charger at low SOC. That would reduce the charge power to 8 kW or 82 amps at 98 volt. when you do it this way, isnt there a 1 hour timeout or something like that?
You will have to switch the bike on with the key but at home that won't be a problem
Could be, i don't know really.
But at 8000 watt charging an hour means 8kwh back in the batterypack,
For my zf11.4 (effective kwhrs 10.4) this is about 80% SOC. For a 2016 zf13.0 plus powertank this is only about 60% though.
Otherwise just charge for 15 minutes without the onboard charger and then just plug it in. The voltage should have risen enough to decrease the amps enough so the total amps stay around 90 instead of 95.
