Abstract
The present disclosure relates to an immersion tolerant electrical energy storage system for use with electric vehicles. The energy storage system is equipped with a sealed battery unit and a sealed heat exchanger that cooperates to inhibit the intrusion of fluids and other contaminants into the system. The ability to limit intrusion of such fluids and contaminants provides improved service life for the batteries in the battery unit and components of the thermal control system.
Claims19
An immersion tolerant electrical energy storage system for a vehicle, the vehicle including an electric motor and a battery pack, the electrical energy storage system comprising:
- an enclosure including first and second housing portions interconnected with a seal mechanism to define a sealed internal chamber within which the battery pack is disposed;
- and
- a thermal management system for thermally managing the battery pack and including a heat exchanger, an external thermal management loop sealed relative to said heat exchanger, and an internal thermal management loop sealed relative to said heat exchanger and said enclosure.
