1. A multi-cell battery control circuit within a battery housing, comprising:
a negative battery terminal and a positive battery terminal that each penetrate and conduct electrical current through the battery housing;a plurality of battery cells coupled electrically in series and having a combined battery potential proportional to the combined sum of the battery cells,
a microcontroller; a battery cell voltage balancer having a discharging circuit and a plurality of differential conductive connections, each of the differential conductive connections respectively coupled to positive and negative terminals of one of the battery cells, the cell voltage balancer also having at least one cell balancing output and at least one cell balancing input to transmit and receive cell voltage balancing information to and from the microcontroller, respectively; a charger having a charger input current sourced from the positive battery terminal, a charger output current sourced to the combined battery potential, and a charger control input coupled to the microcontroller that enables charger output current to be sourced to the combined battery potential; and a contactor series-coupled between the combined battery potential and the positive battery terminal and having a contactor closed state that permits current to flow between the combined battery potential and the positive battery terminal, and an contactor open state that prohibits current flow between the combined battery potential and the positive battery terminal, the contactor having a contactor control input coupled to the microcontroller. |
