Abstract

The invention provides a battery and a battery pack. The battery comprises a shell, a sampling assembly and a battery cell string, wherein the sampling assembly and the battery cell string are arranged in the shell; the battery cell string comprises a plurality of battery cells which are sequentially connected in series, the sampling assembly comprises a circuit board located at one end of the battery cell string and a sampling wire harness used for sampling the battery cells, the sampling wire harness comprises a fixing part and a plurality of sampling wires, the sampling wires are arranged side by side, and each sampling wire comprises a main body, an output section and a connecting section; the output section and the connecting section are arranged at two opposite ends of the main body, the main body is positioned on one side of the battery cell string, the output section is bent and extends towards the other side of the battery cell string relative to the main body, the fixing part is fixed at the joint of the main body and the output section, the output sections of the plurality of sampling lines are welded and conducted with the circuit board, and the connecting sections of the plurality of sampling lines are correspondingly connected with the plurality of battery cells. The sampling wire harness provided by the invention can be conveniently connected with a circuit board, and is beneficial to improving the assembly efficiency.

Description

technical field [0001] The present invention relates to the field of batteries, in particular to a battery and a battery pack. Background technique [0002] At present, with the continuous development of the new energy vehicle industry, the power battery provides the main driving force for it. The power battery pack needs to collect information such as the temperature and / or voltage of the battery during use to understand the current working condition of the battery and avoid There is a safety hazard due to the abnormal operation of the battery. In order to increase the voltage of the battery, multiple cells are set in series inside the battery, and a sampling circuit and a circuit board need to be set to sample the cells. However, the structural design of the existing sampling circuit makes it inconvenient to connect with the circuit board, and then Affect assembly efficiency and increase cost. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to...
