Abstract

According to one embodiment, a battery module includes an output connector, several battery cells that are coupled to the output connector, and several spray nozzles and spray cooling loop and system.The battery cells are configured to provide battery energy to a load via the output connector and are configured to draw power from an external power supply to charge the battery cells via the outputconnector. The spray nozzles are configured to spray coolant on the battery cells to transfer heat generated by the battery cells to the sprayed coolant.

Description

technical field [0001] Embodiments of the present disclosure generally relate to backup thermal management systems for cooling battery packs. More specifically, embodiments of the present disclosure relate to a system for spraying coolant on cells in a battery pack as the cells are discharged and / or charged. Background technique [0002] Lithium-ion batteries are commonly used in the vehicle industry, such as electric vehicles (EV) and plug-in hybrid vehicles. Lithium-ion battery packs for electric vehicles are designed for vehicle-specific requirements and uses. However, lithium-ion batteries are also becoming popular for IT equipment and data centers as an energy storage unit to replace UPS systems and lead-acid batteries, and are attracting a lot of attention from the industry. [0003] Large clusters of computer servers can be maintained in dedicated facilities, usually in rack enclosures. Servers can be used to support the data center industry. The use of battery ba...
