Abstract: An electric drive work machine may include a body frame, a first electric power storage device mounted on the body frame, a second electric power storage device mounted on the body frame, and a junction box mounted on the body frame. The junction box may be operatively connected to the first electric power storage device by a first electric connection having a first inductance, and operatively connected to the second electric power storage device by a second electric connection having a second inductance. The first inductance may be equal to the second inductance such that power source charging power from the junction box is distributed equally to the first electric power storage device and the second electric power storage device, and power source output power to the junction box is drawn equally from the first electric power storage device and the second electric power storage device.

Abstract: A rotary electric machine includes a stator, a rotor, a plurality of coils, and a plurality of flow enhancement members. Each coil has a compound outer surface along major sections thereof with an insulating layer disposed therealong. The compound outer surfaces of each pair of adjacent coils define a channel extending along adjacent major sections of each adjacent pair of coils. One of the flow enhancement members is disposed within each channel between the adjacent major sections of each pair of adjacent coils, with each flow enhancement member defining a gap between the compound outer surface of one of the coils and the flow enhancement member through which cooling fluid may flow.

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.
