Abstract
(EN) The embodiment of the invention discloses a power battery assembly and a vehicle. The power battery assembly comprises a plurality of battery modules arranged in parallel, each battery module comprises a battery cell and a cooling device, the cooling device comprises a cooling plate, the cooling plate comprises an upper plate and a lower plate, the upper plate covers the lower plate, the upper plate and the lower plate jointly form a cooling flow channel, and the battery cell is arranged on the upper plate. Therefore, the plurality of battery modules are assembled to form the power battery assembly, and when a certain battery module of the power battery assembly breaks down, the battery module can be directly replaced to reduce the maintenance cost. Besides, the cooling devices in the power battery assembly can cool the single battery cell, so that the cooling devices in the power battery assembly do not interfere with one another, and the cooling efficiency of the power battery assembly is improved.
(ZH) 本申请实施方式公开了一种动力电池总成和车辆。所述动力电池总成包括并列设置的多个电池模组，每个所述电池模组包括电芯和冷却装置，所述冷却装置包括冷却板，所述冷却板包括上板和下板，所述上板盖合在所述下板上，所述上板和所述下板共同形成冷却流道，所述电芯设置在所述上板上。如此，通过多个电池模组组装形成动力电池总成，当动力电池总成的某个电池模组出现故障时，可直接更换电池模组以减小维修成本。另外，动力电池总成中的冷却装置可以对单个电芯进行冷却，使得动力电池总成中的各个冷却装置互不干扰，提高了动力电池总成的冷却效率。
