Description

technical field [0001] The invention relates to the field of storage battery manufacturing, in particular to energy-saving battery formation equipment. Background technique [0002] A battery is a device that converts chemical energy into electrical energy, and is widely used in every corner of people's lives. The battery formation process is an extremely important process in the battery production process, which requires multiple charging and discharging of the battery. [0003] Traditional high-power battery production still uses energy-consuming chemical formation equipment to charge and discharge batteries. This equipment uses resistive loads, and battery discharge is converted into heat energy release through resistive loads. This method wastes a lot of electrical energy. Some improved equipment uses inverters instead of resistive loads to achieve the purpose of energy saving by inverting the electric energy of the battery into alternating current and feeding it back t...

Problems solved by technology

[0004] In order to solve the above-mentioned shortcomings of high energy consumption of the current resistance-type formation equipment and the fact that the inverter-type formation equipment will pollute the power grid and is not conducive to practical implementation, the present invention provides a built-in supercapacitor and DC / DC conversion circuit. Energy-saving battery formation equipment, which uses supercapacitors as components for temporarily storing electric energy. When the battery is discharged, the released electric energy will charge the supercapacitor. When charging the battery, the supercapacitor charges the battery and recycles electric energy, effectively saving large amount of electrical energy
