The invention relates to equipment for balancing voltage among single bodies in a lithium battery pack. The equipment comprises an equipment shell, a maintenance, protection and stabilization structure and a control unit. Connecting bases are arranged at the four corners of the equipment shell, fixing bolts are installed in the connecting bases, a display screen is embedded in the upper end face of the equipment shell, a wiring harness groove is formed in the lower end face of the bottom plate, the tail end of the wiring harness groove is connected with a plug board matching groove, and the control unit is arranged in the equipment shell. According to the invention, through the arrangement of the connecting wire harness and the plug board, mutual connection with the lithium battery assembly can be facilitated; therefore, the equipment can conveniently perform equalization processing on the lithium battery pack; the plug board with the plug sheet structure can be conveniently plugged into each battery connection point of the lithium battery pack, so that the voltage of each single body in the battery pack can be conveniently subjected to fixed-point connection treatment, and the voltage among the single bodies in the lithium battery pack can be conveniently balanced through the arranged control unit.
Description
technical field [0001] The invention relates to the technical field of lithium battery packs, in particular to a device for equalizing the voltage between individual cells in a lithium battery pack. Background technique [0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is different from a rechargeable battery. Lithium-ion batteries are different from lithium-ion polymer batteries. The inventor of the lithium battery is Edison. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of microelectronics technology at the end of the 20th century, miniaturized equipment is increasing day by day, which puts forward high requirements for power supply. Lithium batteries have ente...
