Abstract

The invention relates to the technical field of new energy vehicles, in particular to a battery pack with replaceable battery cells. The battery pack with replaceable battery cells comprises a batterycell module and a battery pack shell, the battery cell module comprises a plurality of battery cells, an electric appliance connecting box and a battery management system area, and a high-voltage connecting position and a low-voltage connecting position of the battery cells are arranged at the bottom of the battery pack by adopting a quick-plug high-voltage connecting mode; and the lower part ofthe battery pack shell is of a detachable structure. According to the CTP battery pack with the replaceable battery cells, when the battery cells in the CTP battery pack go wrong, the positions of thefaulty battery cells can be determined through a BMS, the positions of the battery cell modules needing to be replaced are determined, the battery cell modules are replaced, the operation process that the battery pack is detached from a vehicle can be omitted, detaching and installing can be completed on a vehicle body, and the efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, and more specifically relates to a battery pack with replaceable batteries. Background technique [0002] As an environmentally friendly and energy-saving alternative to conventional internal combustion vehicles, pure electric vehicles are becoming more and more important. In order to provide electric energy for running the electric motor, the electric vehicle has a rechargeable battery pack, and the effective driving distance of the electric vehicle is proportional to the capacity of the battery pack. [0003] Due to the limited structural space for battery packs in electric vehicles, increasing the capacity of battery packs requires increasing the energy density of the battery pack and maximizing the use of battery pack space, so that the battery pack can carry more energy to improve the driving of electric vehicles milage. [0004] With the development of the new energy industry,...
