用于提高电池安全性的快速冷却系统

Flash cooling system for increased battery safety

Abstract

本发明涉及用于提高电池安全性的快速冷却系统,具体地,提供了一种具有该系统的电池组。例如,在具有分布在多块互相连接的电池模块间的多个电池单元的电池组中,设置了运行期间冷却系统,以在电池单元的常规充电和放电期间冷却(和/或加热)电池单元(例如,给诸如电动车或者混合动力车内的发动机等负载提供电力),以及应急冷却系统,响应于指示一个或者多个指示电池单元或者电池模块内可能发生热失控的条件的检出的信号来冷却电池单元。运行期间冷却系统可以包括风机、HVAC单元或者其他流体泵浦装置,以在电池组内引起连续的冷却剂流。与之相比,应急冷却系统包括机械接口,或者适于容纳包含加压冷却剂的容器或者其他快速冷却装置。
The invention relates to a flash cooling system for increased battery safety. In a battery pack having multiple battery cells distributed, for example, between multiple interconnected battery modules, a run-time cooling system is provided to cool (and/or heat) the battery cells during routine charging and discharging of the cells (e.g., powering a load such as a motor within an electric or hybrid-electric vehicle), and an emergency cooling system to cool the battery cells in response to a signal indicating detection of one or more conditions indicating possible thermal runaway within the battery cells or battery modules. The run-time cooling system, which may include a fan, HVAC unit or other fluid pumping device, induces continuous coolant flow within the battery pack (e.g., flow of air or other gaseous or liquid coolant). The emergency cooling system, by contrast, includes a mechanical interface or is otherwise adapted to receive a receptacle containing pressurized coolant or other flash-cooling device.
