Abstract
Techniques involve controlling battery access on a utility vehicle. Such techniques involve monitoring status of input signals from a group comprising: a lithium battery system, a keyed switch, and a charging receptacle, comparing the status of the input signals to timeout settings stored in memory of the motion control system, initiating a timer based on comparison of the input signals to the timeout settings, and disconnecting at least one direct current (DC) path between a lithium battery interface and a power distribution interface of the utility vehicle in response to expiration of the timer. Such techniques further involve, after disconnecting, reconnecting the at least one DC current path between the lithium battery interface and the power distribution interface in response to a change in status of at least one of the input signals. Such techniques may be performed by a motion control system of the utility vehicle.
