Battery assembly

Abstract

The invention provides a battery assembly. The battery assembly comprises at least one first battery module, at least one second battery module and a conductive element, wherein the first and second battery modules are arranged separately, each battery module comprises at least two batteries, and each battery is provided with a positive electrode and a negative electrode; and the conductive element comprises a first part connected in parallel with the two positive electrodes of the at least two batteries of the first battery module, a second part connected in parallel with the two negative electrodes of the at least two batteries of the second battery module, and a third part connected in series with the positive electrode of one battery of the first battery module and the negative electrode of one battery of the second battery module. Compared with the prior art, the battery assembly has the advantages that: series connection and / or parallel connection among a plurality of batteries can be realized by one integrated conductive element, and the connecting parts of the conductive element are flat, so that the conductive element can bear high over current. Furthermore, the number of the flat connecting parts can be multiple, so that the over current capacity of the conductive element is enhanced.

Description

technical field [0001] The invention relates to a battery assembly, in particular to a conductive member in the battery assembly. Background technique [0002] In recent years, considering the increasingly severe environmental pollution, storage batteries, which can be charged or discharged, are often used as a power source to replace traditional fossil fuels to solve the environmental pollution problems caused by fossil fuels. In the field of vehicle power, compared with traditional energy sources, electric power sources have obvious advantages in terms of environmental protection. Using batteries as the power source does not consume gasoline, has no exhaust gas, low noise, and low radiation, which is an ideal power source. At present, commonly used electric power sources usually use multiple single cells placed in a battery module frame, and then electrically combine the single cells through series-parallel modules to form a battery module to meet the power demand.

AI Technical Summary

Problems solved by technology

[0003] At present, each battery in the same module is usually connected through a point-to-point connection. This connection method is not suitable for the connection between multiple batteries, because the charging and discharging current between multiple batteries is relatively large, and ordinary connecting wires May be blown due to inability to carry too much overcurrent
