A charging system charges a lithium battery of a utility vehicle. The charging system includes a receptacle configured to couple with an external charger, a lithium battery configured to provide lithium battery power to a set of electrical loads of the utility vehicle, and control circuitry coupled with the receptacle and the lithium battery. The control circuitry is configured to detect connection between the external charger and the receptacle and, in response to detecting connection between the external charger and the receptacle, ascertain a charging state of the lithium battery. The control circuitry is further configured to output, based on the charging state, a control signal to the external charger through the receptacle, the control signal being configured to control charging output from the external charger to charge the lithium battery.
