Abstract
A coupled battery and motor controller thermal management system is disclosed. In various embodiments, a motor controller and a heat sink are coupled thermally to a battery. At least a portion of waste heat generated by the motor controller is transferred to the thermal mass of the battery during at least a first mode of operation in which a relatively low amount of ambient air flows through the heat sink.
Claims18
An assembly, comprising:
- a battery having a thermal mass;
- a motor controller coupled thermally to the battery;
- and
- a heat sink coupled thermally to the battery, the heat sink including a plurality of thermally conductive fins arranged in an array defining one or more airflow channels through the heat sink;
- wherein the airflow channels are structured to direct at least a portion of waste heat generated by the motor controller:
- to be stored in the thermal mass of the battery during at least a first mode of operation of the motor controller in which a lower amount of ambient air flows through the heat sink, and
- to flow out of the battery during at least a second mode of operation of the motor controller in which a higher amount of ambient air flows through the heat sink.
