The invention discloses a battery pack fused with a vehicle body and a vehicle with the battery pack. The battery pack comprises an upper component, a lower box body, a high-low voltage assembly part and a battery module, the upper component comprises an upper cover body, a front cross beam, a rear cross beam, a left longitudinal beam and a right longitudinal beam, and the upper cover body is arranged above the front cross beam, the rear cross beam, the left longitudinal beam and the right longitudinal beam; the lower box body is arranged on the lower portions of the transverse longitudinal beams, and the lower box body, the upper cover body and the transverse longitudinal beams define a containing cavity. The high-low voltage assembly part and the battery module are arranged in the accommodating cavity; the space is effectively utilized, a high-voltage element and a low-voltage control part in the battery are integrated, a module and a high-low-voltage assembly part are arranged in independent areas in the lower box body in a partitioned manner, and an internal low-voltage cable adopts a flexible wire bar to perform electric and signal connection on the module and the high-low-voltage assembly part, so that conformal design of internal wiring harnesses is facilitated; the safety of the battery system is improved, the weight is reduced, and the cost is saved.
本发明公开了一种融合车身的电池包及具有其的车辆,电池包包括上部组件、下箱体、高低压集合部件和电池模组;上部组件包括上盖本体、前横梁、后横梁、左纵梁和右纵梁,上盖本体设置于前横梁、后横梁、左纵梁和右纵梁上方;下箱体设置于横纵梁下部,且下箱体、上盖本体、横纵梁围设成容纳腔;高低压集合部件以及电池模组设置于容纳腔内;本发明有效利用空间,电池内部高压元件与低压控制部件集成,模组与高低压集合部件分区布置于下箱体内部单独区域,内部低压线缆采用柔性线排将模组与高低压集合部件进行电与信号连接,便于随形设计内部线束简洁,提升电池系统安全性,且降低重量且节约成本。
