Abstract
A thermal management module includes a first compartment including one or more of a coolant pump, a coolant valve, and a coolant conduit. A conjoined second compartment includes one or more of a valve actuator, an electronic control module, a system pressure sensor, a temperature sensor, and a heat exchanger. In certain embodiments, the first compartment is enclosed in a first modular enclosure and the conjoined second compartment is separately enclosed within a second modular enclosure.
Claims20
A thermal management module, comprising:
- a first compartment including a flood conduit that floods a compartment of a battery pack with a liquid coolant to short-circuit a terminal of a battery cell in the compartment when a battery pack fails, the first compartment further including one or more of a coolant pump, a coolant valve, a coolant conduit;
- and
- a conjoined second compartment including one or more of a valve actuator, an electronic control module, a system pressure sensor, a temperature sensor, and a heat exchanger,
- wherein the first compartment is enclosed in a first modular enclosure and the conjoined second compartment is separately enclosed within a second modular enclosure.
A method of preventing a thermal runaway event in an electrical vehicle battery of an electric vehicle comprising:
- detecting by a sensor a failure of a vehicle battery pack;
- delivering a coolant from a thermal management module to the vehicle battery pack after an indication by the sensor of a battery pack failure;
- and
- flooding a compartment of the battery pack with the coolant to short-circuit a terminal of a battery cell in the compartment;
- wherein the coolant includes a liquid coolant.
