[0002] At present, the science and technology industry has gradually tried to reduce the use of polluting energy sources such as burning oil and natural gas, which have limited storage and cause a large amount of carbon emissions. Electric energy is a clean energy source. However, many vehicles currently use oil and natural gas as the driving energy required for driving. Therefore, in order to reduce the demand for oil and natural gas, electric vehicles that use electricity as the driving energy have become popular. issue

[0003] However, transportation tools such as electric vehicles are limited by the need to consume a large amount of electric energy to drive the motor, so a large number of battery cells must be used, and the stored electric energy can be increased by connecting the battery cells in series/parallel. Must cope with severe temperature and operating environment tests, and even the possibility of accidental collision must be considered. For multiple battery cells connected in series/parallel, due to the impact of vibration in all directions, the connection between the battery and the battery may fall off or occur. The possibility of short circuit increases. If some batteries are disconnected due to the disconnection of the contacts, the power supply energy will be reduced, resulting in the failure of normal driving. However, if an external short circuit occurs, it may cause a single battery cell to burn due to the instantaneous high temperature. Explosion, and then spread to adjacent battery cells, causing serious safety problems. Therefore, in current designs, individual battery cells are generally connected to the overall circuit through a fuse, so that when a single battery cell has an external short circuit, it will be active. Open circuit, reducing interference to the overall circuit

[0004] However, when the battery cell is charging and discharging, the temperature of the battery cell and the circuit will also increase due to the passage of a large amount of current. Due to the limitation that the positive and negative electrodes of the battery cell must be equipped with electrodes to conduct elec
