The invention relates to the technical field of batteries, and provides an electric vehicle battery. The electric vehicle battery comprises a shell and a battery module, wherein the shell comprises abottom shell, a middle shell and an upper shell which are detachably installed, and the upper shell is provided with a wired plug electrically connected with the battery module; the battery module comprises a framework, a BMS module and a plurality of lithium batteries, and the BMS module is electrically connected with the lithium batteries and the wired plug; the framework is detachably connectedwith the bottom shell, and the middle shell and the framework shell are assembled in a sliding mode; and a wireless charging module electrically connected with the BMS module is arranged in the bottom shell. The shell is divided into three detachable parts, namely, the upper shell, the middle shell and the bottom shell, so that the installation complexity of the shell and the battery module is reduced. Meanwhile, detachable installation between the framework and the bottom shell is achieved through a second locking piece, so that the installation of the battery module is further facilitated.The bottom shell is provided with the wireless charging module at same time, and wireless and wired charging modes of the electric vehicle battery are achieved, so that the electric vehicle battery has the advantages of being convenient to install and diversified in charging mode.
Description
technical field [0001] The invention relates to the technical field of batteries, and in particular provides an electric vehicle battery. Background technique [0002] With the enhancement of global environmental protection awareness, in response to the environmental protection policy of energy saving and carbon reduction, electric vehicles are gradually favored by everyone. They are non-polluting, meet environmental protection requirements, are safe and fast, and make electric vehicles more and more widely used. [0003] Electric vehicle batteries are the main source of power for electric vehicles, and the quality of electric vehicle batteries directly affects the performance of electric vehicles. Existing electric vehicle batteries generally include a casing and a battery module. The installation method between the battery module and the casing is generally more complicated. At the same time, welding is used to increase the firmness of the battery module installation. Aft...
