Abstract: A system controls charging of a rechargeable battery. The system includes a rechargeable battery configured to provide rechargeable battery power to a set of electrical loads (e.g., an electric motor of a utility vehicle). The system further includes a connector configured to connect to a charger, and control circuitry coupled with the rechargeable battery and the connector. The control circuitry is operative to (i) sense a charge management event, (ii) in response to the charge management event, connect the rechargeable battery to the connector and disconnect the rechargeable battery from the connector to provide a message to the charger through the connector (e.g., via opening and closing a contactor), and (iii) after communicating the message to the charger, manage connection between the rechargeable battery and the charger to control charging of the rechargeable battery through the connector (e.g., via opening and closing the contactor).
