Abstract

The invention provides a battery module, which includes a battery pack, a sampling module and a casing. The battery pack includes several single cells and power connection pieces, and the power connection pieces are electrically connected to adjacent single cells. The casing is wrapped around the battery pack and the sampling module. The sampling module includes a flexible circuit board and a protection device. The flexible circuit board is electrically connected to a number of temperature sensors and voltage sampling terminals. The temperature sensor is connected to the power connection piece, and the voltage sampling terminal is electrically connected to the power connection piece. The inner insulating layer, the outer insulating layer covers the outer surface of the flexible circuit board, and the inner insulating layer is wrapped between the power connecting piece and the single battery. The invention solves the problems of complex assembly, error-prone and frequent leakage due to wire sheath wear in the traditional wire harness connection sampling method in the power battery field, and provides a battery module with high reliability, simple assembly and safety.

Description

technical field [0001] The invention belongs to the field of power batteries, in particular to a battery module. Background technique [0002] With the exhaustion of petroleum energy and the improvement of people's requirements for environmental protection, it has become an inevitable development trend for electric vehicles or hybrid vehicles to replace the current fuel vehicles. Therefore, as the core power source of electric vehicles - the battery module, its importance is particularly prominent. [0003] The vehicle power battery requires a large capacity of the battery module, which brings problems such as large volume and complex structure of the battery module. Since battery modules are generally composed of hundreds of single cells connected in series, in mass production, the connection between each single cell is complicated. At the same time, in order to ensure the safety performance of the vehicle power battery, it is necessary to monitor the temperature and volt...
