The invention discloses an electric vehicle-mounted lithium battery which comprises an upper cover, a shell and a battery pack; the upper cover is detachably connected with the upper end of the shell,and a closed cavity is formed in the shell after the upper cover and the shell are connected; the battery pack is mounted in the closed cavity; a positive female head and a negative female head are embedded in the upper cover; and the positive female head and the negative female head are connected with the battery pack. According to the invention, the positive and negative female heads are embedded in the upper cover in a distributed manner and are arranged on one side of the same plane in the upper cover, so that the problems of wire skin breakage, water leakage, short circuit and the like caused by an outgoing line mode outside the lithium battery shell and the common problem of short circuit caused by an integrated mode of positive and negative plugs are solved; therefore, the high safety standard of easy storage, no short circuit and no water leakage of the lithium battery is realized, and the PACK cost is reduced; and the lithium battery is simple in structure and high in use efficiency.

    本发明公开了一种电动车载锂电池,包括上盖、壳体和电池组;所述上盖可拆卸连接于所述壳体上端,且二者连接后内部形成一密闭空腔;所述电池组安装于所述密闭空腔内;所述上盖内嵌设有正极母头和负极母头;且所述正极母头与所述腹肌母头均与所述电池组连接。本发明通过将正负极母头分布式嵌于上盖内且设置于所述上盖内同一平面的一侧,解决了锂电池壳外出线方式造成的电线破皮、漏水短路等问题,以及正负极插头一体方式导致短路的常见问题;从而实现锂电池易储存、不短路、不漏水的高安全标准,并降低了PACK成本,而且本发明结构简单、使用效率高。
