Abstract
Techniques involve managing lithium battery access on a utility vehicle. In accordance with such techniques, a wakeup circuit includes a set of inputs, a set of outputs, and control logic coupled with the set of inputs and the set of outputs. The control logic is constructed and arranged to, in response to detecting a wakeup event from circuitry of the utility vehicle via the set of inputs, close a switching apparatus of the utility vehicle via the set of outputs to connect a lithium battery of the utility vehicle to a set of loads of the utility vehicle. The control logic is further constructed and arranged to, in response to detecting a sleep event, open the switching apparatus via the set of outputs to disconnect the lithium battery of the utility vehicle from the set of loads of the utility vehicle.
