(54) | BATTERY PACK COOLING SYSTEM CAPABLE OF PREVENTING THERMAL RUNAWAY PROPAGATION OF BATTERY PACK, AND WORKING METHOD OF BATTERY PACK COOLING SYSTEM |
(57) The present application discloses a battery pack cooling system capable of preventing
propagation of thermal runaway of a battery pack and a working method thereof. The
battery pack cooling system capable of preventing the propagation of the thermal runaway
of the battery pack includes at least a cooling fluid guide assembly, at least a refrigeration
element, at least a heat exchange element, at least a thermal runaway sensing element,
and at least a fluid diversion assembly. The cooling fluid guide assembly includes
a plurality of cooling fluid circulation pipelines and at least an electronic water
pump. The electronic water pump is configured to be communicatively connected to a
controller of a vehicle and is arranged on the cooling fluid circulation pipelines,
the refrigeration element communicates with the cooling fluid circulation pipelines,
the heat exchange element communicates with the cooling fluid circulation pipelines.
The thermal runaway sensing element is configured to be communicatively connected
to the controller. The fluid diversion assembly includes at least a fluid guide channel
and at least a fluid diversion valve. The fluid diversion valve is set as a multi-way
solenoid valve, and has at least two interfaces configured to communicate with the
cooling fluid circulation pipelines, and at least one interface communicating with
one end of the fluid guide channel.
