- SC sends commands periodically specifying the (minimum) boost converter output voltage.
- boost converter is not normally active or switching
- battery terminals are not normally live. thus impossible to externally short.
- external power enabled when battery inserted into ankle
- micro power hall sensor senses magnet and enables BAF
- high impedance source that is 'shorted' when connected to ankle and enables BAF
- BAF 'soft starts' ankle - avoiding inrush current
- low voltage (fuel gauge) shutoff - each cell voltage monitored
- impedance tracking of each cell?
- fuel gauge : micropower current sensor that integrates (dis)charge
- electronic fuse : SC sends commands periodically that specify the maximum amount of current and/or power allowed.
- internal charger and ballancer
- inductive charging.
