Electric vehicle power battery standard modularization and application thereof

Disclosed are an electric vehicle power battery standard modularization and an application thereof. Unified standard modules with exchangeability are used in all electric vehicle power batteries, a quick-changing technology is utilized in the modules to guarantee convenient and swift exchange, the lower battery standard modules are connected in parallel, different parallel combination can meet different power output and cruising ability requirements, in practical usage, the power battery standard modules are controlled in a mode of sequentially discharging in order and by every group, a network of power battery quick-changing stations of electric vehicles can be established by referencing the density of gas stations, also, an existing gas station network can be changed into battery fast-changing stations, a user can replace the power modules of an electric vehicle, which is run out in electricity, with the fully-charged battery modules at the power battery quick-changing stations, and the power modules withou
