Problems solved by technology

[0004] Obviously, for suppliers who manufacture and provide battery packs, the process of assembling a battery pack with a predetermined space from multiple battery modules is cumbersome and requires manpower to connect the battery modules separately. At the same time, there is also a hidden worry that if a single battery module fails in the future, it cannot be replaced easily and individually

Abstract

A combined battery pack comprises at least one battery string and at least one connector, wherein each battery string comprises at least two battery modules, each battery module is provided with a shell and an energy storage unit, the shell comprises two vertical walls separated from each other, the energy storage unit is used for storing electric energy and providing the stored electric energy tooutside, the energy storage unit is arranged between the vertical walls and comprises two polar ends, the two polar ends respectively get close to the two vertical walls, each connector is used for connecting at least two adjacent battery modules and comprises a base wall and two clamping walls, the base wall is embedded into the shells of the two adjacent battery modules, the two clamping wallsare respectively connected with two opposite ends of the base wall, and at least one of the two clamping walls is attached onto the vertical walls of the shells of the two adjacent battery modules andis in contact with the polar ends of the two adjacent battery modules so that the two battery modules are electrically connected. Therefore, the battery module connection process is simplified, and asingle battery module is convenient to independently and subsequently replace.

Description

technical field [0001] The invention relates to a battery, in particular to a vehicle battery. Background technique [0002] At present, the battery packs used in electric vehicles are based on the power demand and the original design of the installation space in the car. After arranging multiple battery modules of a single specification, they are connected in series or in parallel with cables. The battery modules are electrically connected, and then the battery modules are wrapped into battery packs before being placed in the installation space of the electric vehicle for subsequent use. [0003] refer to figure 1 For example, when the battery pack 1 used in an electric vehicle requires six single battery modules 11 to be connected in series to provide electric energy, and the space pattern of the battery pack 1 designed for installation in the electric vehicle is a cuboid, the battery supplier According to this requirement specification, select six battery modules 11 wit...
