Problems solved by technology
However, this solution leads to the additional drawback
For example, with this solution, the area or part of the busbar intended for the connection between the batteries would have an increased resistance, which is disadvantageous
Furthermore, in this case the busbar has sections of varying dimensions in some parts, this transition due to the change in cross-sectional dimensions may lead to turbulent flow and adversely affect the EMC performance of the busbar

The invention provides a busbar for a battery, a corresponding battery system and a vehicle. The busbar comprises a main body area and a plurality of extension parts which extend from the main body area and are spaced in the longitudinal direction of the main body area, and each extension part is provided with an end part for connecting the battery and a connecting part for connecting the end part to the main body area; each connecting part comprises a first part extending from the main body area in the extending direction of the extending part and a second part between the corresponding end part and the first part, the section of the first part in the longitudinal direction is gradually reduced in the extending direction, and the section of the second part in the longitudinal direction is gradually increased in the extending direction; and the junction part of the first part and the main body region and the junction part of the second part and the end part are smooth. With the present invention, it is possible to completely or partially avoid turbulence and consequences associated therewith while increasing the thermal resistance of the busbar to reduce heat propagation.
Description
technical field [0001] The present invention relates to busbars, and more particularly, to a busbar for a battery and a corresponding battery system and vehicle. Background technique [0002] In high voltage battery systems, bus bars are often used to connect two or more batteries. Depending on the situation, these cells can be connected in parallel and / or in series. The main function of the busbar is to make electrical connections. The busbars are usually made of metal, which means that the busbars have good thermal conductivity. In some cases, one of the cells connected to the busbar may run away thermally, and how to reduce the heat transfer is a problem. [0003] In view of the above problems, the existing solution is to reduce the cross section of a certain part of the bus bar, thereby reducing the heat transmission by increasing the thermal resistance. However, this solution leads to further drawbacks. For example, with this solution, the area or part of the busba...
