Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage batteries, and particularly relates to a positive soft copper bar and an energy storage battery. Background Art

[0002] At present, in the energy storage industry, copper bars have the characteristics of high current and high voltage load. Copper bars are used to connect each battery module in series in the PACK box and play a role in connecting and conducting electricity.

[0003] When assembling the PACK, usually four copper bars are required. Workers need to install one end of each copper bar on the module respectively in the limited space at the front end of the PACK, and the other end is connected to the high-voltage connector or MSD. After arranging the positions of the four copper bars, they are installed on the front panel. The front panel is provided with high-voltage plugs and MSDs connected to the copper bars, so that the current inside and outside the PACK box is connected to form a loop, and the whole system can operate effectively. However, due to the compact position at the front end of the PACK, the four copper bars need to be installed in a certain order and with attention to the position space. In particular, attention needs to be paid to the installation order and position during installation, otherwise the installation may not be successful. One of the four copper bars is the positive copper bar. During the installation process, since the size of the positive copper bar is fixed and it is not easy to change its length, usually one end of the positive copper bar is connected to the module first, and then the upper shell is installed. The other end of the positive copper bar needs to be installed on the high-voltage connector pre-installed on the panel. However, it is very difficult for the positive copper bar with a fixed size to be successfully installed according to the installation requirements. Eventually, the positive copper bar cannot be connected to the positive high-voltage generator, resulting in the inability of the current to flow, and the entire loop forms an open circuit, and the electrical energy of the energy storage PACK battery cells cannot be exchanged with the outside.

[0028] Compared with the prior art, the positive electrode flexible copper bar provided in this embodiment is provided with an elastic compensation portion 3 between the first connecting member 1 and the second connecting member 2. After the first connecting member 1 is connected to the positive electrode of the module, the second connecting member 2 is smoothly connected to the positive electrode high-voltage generator on the panel by adjusting the elastic compensation portion 3, so that the current flows normally, forming a closed loop, and realizing the AC of the electric energy of the energy storage PACK battery core with the outside world; at the same time, due to the limited space inside the PACK, during the actual installation process, the staff adjusts the angle and relative position relationship between the first connecting member 1 and the second connecting member 2, and finally facilitates the layout of the positive electrode flexible copper bar in the limited space of the PACK; it not only solves the technical problem that the positive electrode copper bar and the high-voltage plug-in cannot be normally connected in the prior art, but also solves the technical problem that it is not easy to place the positive electrode flexible copper bar due to the limited space inside the PACK.
