[0002] A temperature and pressure sensing integrated busbar typically includes components such as a support plate, test pieces, and test tanks. The test pieces are electrically connected to the test tanks and are used to collect the voltage and temperature signals of the battery. Currently, the test pieces are connected to the test tanks via pressure sensing nickel plates and temperature sensing nickel plates, and then two lines are led out to connect to the fuse. The fuse is welded to the base plate, and the support plate provides support for the busbar.

[0003] However, in current battery testing, multiple power sources are installed on the busbar, and the voltage and temperature sampling nickel plates also need to be welded into the test tank. Welding is not only time-consuming, but also requires replacing both the test tank and the nickel plates at the same time, resulting in high costs and low efficiency. In addition, fuses also need to be welded, which is costly, and the replacement requires resoldering, leading to solder residue.

[0004] Therefore, we urgently need an integrated busbar for temperature and pressure sensing and protection. Utility Model Content
