Abstract

The invention is suitable for the field of battery production, and provides a battery fluid filling device and method. The battery fluid filling device comprises an upper fluid storage container, a lower fluid storage container, a fluid filling pump, a first vacuumizing pump and a second vacuumizing pump, wherein a first valve is arranged between the fluid filling pump and the upper fluid storage container, and a second valve is arranged between the upper fluid storage container and the lower fluid storage container. The battery fluid filling device also comprises a first air source connecting pipe and a second air source connecting pipe which are used for being connected with a dry air source, wherein a third valve is arranged among the first vacuumizing pump, the first air source connecting pipe and the upper fluid storage container, and a fourth valve is arranged among the second vacuumizing pump, the second air source connecting pipe and the lower fluid storage container. The battery fluid filling device is adopted in the battery fluid filling method. According to the battery fluid filling device and method provided by the invention, the fluid filling efficiency is improved, the production cost is lowered, the volatilization of electrolyte is reduced, and the safety is good.

Description

[0001] technical field [0002] The invention belongs to the technical field of battery production, and in particular relates to a battery liquid injection device and a battery liquid injection method. [0003] Background technique [0004] As a new type of energy storage power supply, lithium-ion batteries have the advantages of high energy, high working voltage, wide working temperature range, small size, and long storage life. It is gradually replacing nickel-metal hydride batteries and nickel-hydrogen batteries. With the shortage of energy and the pressure of the world's environmental protection, large-capacity power batteries have gradually become the main force of power supplies; because they will not cause secondary pollution and have no memory effect, etc., they will gradually become the first choice for future market applications of power supplies. Lithium-ion power batteries are widely used in hybrid vehicles, electric vehicles, electric bicycles, electric han...
