Embodiment 1

[0036] Embodiment 1: as figure 1 , figure 2 As shown, a power battery module that is convenient for automatic assembly includes several roughly rectangular soft-packed cells 11 and two bus bars 2, and each soft-packed cell is arranged side by side along its thickness direction. A tab 12 consisting of positive tabs and negative tabs arranged at intervals is provided on the side. For convenience and description, the direction in this embodiment is based on the soft-packed battery cell, where the side where the tab is set is the upper side, and the thickness direction of the soft-packed battery cell is the front and rear sides, and the left and right sides are determined accordingly. The positive tabs of each soft-packed battery cell are linearly arranged from front to back to form a positive tab string, and the positive tabs are connected through a bus bar; correspondingly, the negative tabs of each soft-packed battery cell are arranged linearly from front to back to form a ne...

Embodiment 2

[0046] Embodiment 2: An electric vehicle includes a power battery. Specifically, the power battery is composed of several power battery modules connected in series, and the power battery module adopts the power battery module described in Embodiment 1 that is convenient for automatic assembly.

Abstract

The invention discloses a convenient-to-assemble automatically power battery module and an electric motor car. The electric motor car adopts the power battery module; the power battery module comprises a plurality of soft pack battery cells; positive electrode lugs of each soft pack battery cell are connected via a bus bar, correspondingly, negative electrode lugs of the soft pack battery cell are connected via another bus bar; the two bus bars are arranged oppositely side by side; electrode lug grooves are formed in edges on the opposite sides of the two bus bars at intervals respectively; bell mouths, which are larger and larger gradually, are formed in corners at the opening of the electrode lug grooves; the electrode lugs of the soft pack battery cells are clamped in the corresponding electrode lug grooves of the bus bars on two sides sequentially, extend out of the upper ends of the bus bars, and then bend to cling to and be connected to the upper surfaces of the bus bars. The convenient-to-assemble automatically power battery module is simple in integral structure, the soft pack battery cells can be connected with the bus bars conveniently, automatic assembly can be realized, the assembly efficiency is high, the outline after packing is regular, and the soft pack battery cells are low in damage possibility.

Description

technical field [0001] The invention relates to the technical field of power batteries for vehicles, in particular to a power battery module convenient for automatic production and an electric vehicle using the power battery module. Background technique [0002] Lithium-ion battery technology has become more and more mature, so it is widely used in power batteries for vehicles. The pouch cell battery pack is to put a number of roughly rectangular pouch cells side by side into a fixed shell, and then pack the pouch cells The tabs of the cells are connected in parallel through bus bars to form a pouch cell module. When in use, several pouch cell modules can be connected in series and parallel again to form a power battery as needed. Due to the advantages of light, thin, long cycle life, good safety performance, high energy density, stable discharge platform, excellent power performance, environmental protection and pollution-free and many other advantages of the soft pack bat...
