SYSTEM AND METHOD TO CONNECT AND DISCONNECT ONE OR MORE LITHIUM-ION BATTERY

A power system includes an external-battery-power terminal configured to receive an external-battery-power connector, an external battery emergency power off (EPO) terminal, and an EPO switch coupled to the EPO terminal. The EPO switch is configured to be triggered by decoupling a mechanical latch associated with the external-battery-power connector. An EPO signal is manipulated when the EPO switch is triggered to decouple a battery from the external-battery-power terminal.
