Description
Technical Field

Background
Thermal management of the lithium battery pack is critical not only to battery life, but also to battery safety.
The traditional battery pack heat management method, namely the air cooling technology, can not meet the requirement of the protection level of the lithium battery pack, and the great temperature difference between the battery core and the battery core is caused due to the great temperature difference of the inlet and the outlet of the air cooling system, so that the lithium battery is greatly damaged, and therefore, the use value is basically not available at present.
The traditional lithium battery pack heat management method with high protection level generally adopts a liquid cooling mode, a liquid cooling bottom plate adopted by most manufacturers at present only sets up a single liquid cooling plate at the bottom of a battery pack, the single liquid cooling plate heat dissipation mode at the bottom of the battery pack can cause great temperature difference in the interior of a battery monomer, and the damage to the battery is great when the battery is rapidly charged and discharged and preheated at low temperature. Only tesla employs all battery full side surface liquid cooling mode. However, at present, the liquid cooling medium is directly cooled by antifreeze or refrigeration medium, and the latter is equivalent to a direct expansion evaporator.
