According to the power battery stack and the motor vehicle with the power battery stack, a traditional battery pack is composed of hard-pack battery cells, the battery stack is formed by connecting a large number of soft-pack batteries in parallel and then in series, a parallel assembly and a clamping component used for packaging are formed by machining extruded aluminum profiles, and the parallel assembly and the clamping component are fastened, installed, ejected and disassembled through screws; the cooling medium and the parallel closing-up component form a closed cooling channel, and the cooling medium can be gas or liquid; sealing and water proofing are achieved through the upper cover plate and the lower cover plate, the battery stack is connected with a frame through a heat insulation structure, and heat dissipation in summer and heat preservation in winter are enhanced through the two protection plates. The reliability of the cell stack is improved, the service life of the cell stack is prolonged, suppliers of the soft package cells are wider, standardization and automation of assembly are easier to realize, and the cost is further reduced.
本申请提供了一种动力电池堆及具其的机动车,传统的电池包由硬包电芯组成,本申请的电池堆由大量软包电池并联再串联成组成,封装所用的并联组件、夹持部件由挤出铝型材加工而成,用螺丝紧固安装和顶出拆开,与并联收口部件一起构成封闭的冷却通道,冷却介质可为气体或液体;通过上下盖板实现密封防水,电池堆通过一种隔热结构与车架连接,并通过两种护板加强夏季散热和冬季保温。本申请提高了电池堆的可靠性和寿命,软包电芯供应商更广泛,装配也更容易实现标准化、自动化,进一步降低了成本。
