Abstract

The invention relates to a battery pack and an electric vehicle. The battery pack comprises a cell module, a function module and a connecting member. The cell module comprises a first housing and a cell unit, the cell unit is encapsulated in the first housing, a first conductive terminal is led out from the cell unit and can be touched from the outside of the first housing. The function module consists of a second housing and a function unit, the function unit is encapsulated in the second housing and is provided with a second conductive terminal, also the second conductive terminal can be touched from the outside of the second housing, the first housing and the second housing are in detachable connection through the connecting member, when the first housing and the second housing are in connection, the first conductive terminal and the second conductive terminal can be connected, and when the first housing and the second housing are separated, the first conductive terminal and the second conductive terminal can be separated. The technical proposal realizes partial disassembly and assembly of the cell module, and disassembly and assembly become more convenient. The invention also relates to an electric vehicle equipped with the battery pack.

Description

technical field [0001] The present application relates to the technical field of batteries, in particular to a battery pack and an electric vehicle. Background technique [0002] A battery pack usually includes a battery box, a cell unit and a BMS control component. The battery unit is used to provide electric energy; the BMS control component is electrically connected to the battery unit, and is used to monitor the temperature, current, and power content of the battery unit and output / input various control signals; the battery box is used as a fixed The carrier of the battery cell unit and BMS control components. [0003] In the related art, the battery cell unit and the BMS control component are packaged together in a battery box to form a battery pack, and the battery pack is fixed on the vehicle body as a whole. [0004] However, with the structure of the above-mentioned battery pack, when the power of the battery cells is insufficient, if the fully charged battery cel...
