Indications of charging activity:
- The dash charging light will flash while charging.
- The dash charging light will be solid once fully charged.
- The BMS front indicator window shows 4 LEDs.
- The number of LEDs lit indicates the SOC level in quarters.
- Voltage (verifiable with the mobile app)
- Battery voltage will rise with its state of charge while charging from below 20% and then stays relatively constant (easing from 100V to 104V) from 20% to 80% where it starts rising again.
- A Zero battery will have a full charge when it has 116V while at rest.
- During a charging session, the voltage will dynamically increase by as much as 1V so expect 117V at the end of a full charge until charging stops.
Indications for the Zero battery state of charge while charging may have a significant inaccuracy at high charge rates.
- Typically, indicated SoC will lag (lower than) actual SoC towards the upper end of the range (80% - 100%).
- Turning the motorcycle off and letting the contactor open and waiting for several seconds should restore charge accuracy.
- The BMS historically would thereby reset its method of SoC estimation to a static voltage-based method.
The battery will charge most efficiently between roughly 20% and 80% state of charge, with voltage high enough that current limits allow more power input.
- At higher voltages, chargers taper out of concern to maintain battery condition.
