A battery system (10) includes a plurality of battery cells (12) arranged in a battery housing (16). A cell housing (18) of a respective battery cell (12) and/or the battery housing (16) have/has at least one degassing opening (20) through which a stream of gas can escape along a predetermined degassing path (26) into the surroundings of the battery cell (12) and/or the battery system (10). A spark arrester (24) prevents sparks and/or particles from being released into the surroundings together with the stream of gas and from igniting the stream of gas there. The spark arrester (24) also acts as a heat exchanger for the stream of gas. The spark arrester is designed to slow down the stream of gas and to direct it along a surface of the spark arrester (24) such that it flows along the surface for at least a predetermined period of time. Therefore, thermal output energy is extracted from the stream of gas such that a temperature of the stream of gas when escaping into the surroundings has dropped to a value below a predetermined limit temperature value.
一种电池系统(10),具有多个布置在电池壳体(16)中的电池单体(12),每个电池单体(12)的单体壳体(18)和/或电池壳体(16)具有至少一个排气开口(20),气流可以沿着预定的排气路径(26)通过该排气开口释放到电池单体(12)和/或电池系统(10)的周围环境中。火花阻挡装置(24)防止火花和/或颗粒随着气流流到周围环境中并在环境中点燃气流。火花阻挡装置(24)在此还额外起到用于气流的热交换器的作用。火花阻挡装置被设计成使气流减速并沿着火花阻挡装置(24)的表面引导气流,从而气流至少在预定的持续时间内沿着表面流动。由此使从气流中提取热输出能量以使气流在释放到周围环境中时的温度值下降到比预定的温度限值低。
