Firmware ID: Roboteq v1.7 BMS 05/12/2021 (Older firmware same issues)
BMS configured automatic switch mode (all switches). At some point of time, when robot undock and disconnect from charger BMS is NOT turning off charge switch. As result it keep on showing voltage on charge input. If connect/disconnect charger again situation not changing. Helping BMS reset.
If your robot is configured to use this value as part of success docking detection and you use automatic switch mode, then you will be in issue. Appear rare (1-2 time per month).
Appears on all BMS1040A we have (around 10 items).
