Abstract

A charging system for a battery-operated machine is disclosed. The charging system includes a charging receptacle having a power connection and a signal connection, with the charging receptacle configured to receive electrical current via the power connection from a power supply plug. The charging system further includes a heat rejection element thermally coupled to the charging receptacle, a temperature sensor, and a charging controller operatively coupled to the temperature sensor and the charging receptacle. The charging controller is configured to receive a temperature signal from the temperature sensor, the temperature signal being indicative of a charging-receptacle temperature. The charging controller is further configured to transmit, via the signal connection to the connected plug, a control signal to adjust (e.g., raise or lower) the electrical current supplied to the power connection.
