Battery gas-discharging equipment and use method thereof

Abstract

The invention provides battery gas-discharging equipment and a use method thereof, which are used for reducing abandonment possibility due to battery breakage and causing power batteries to be more practical. The battery gas-discharging equipment comprises a box body, wherein the box body is movably provided with a box cover, a vacuum pumping pipeline port communicated with the inside and outsideof the box body and a scavenging air valve; the box body is connected with a vacuum pumping device by the vacuum pumping pipeline port; a box body wall or the box cover is provided with a spindle in a motive seal penetration mode; and one end stretching into the box body, of the spindle is provided with a matching part which is matched with safety valves of the batteries. The battery gas-discharging equipment can carry out vacuum air discharge on the batteries after the batteries are formed and before the batteries leave a factory, so that a great quantity of gases generated by the formed batteries can be discharged, and the batteries are sealed when the inside of each battery is in a negative pressure state, thus avoiding the battery abandonment caused by breakage of an explosion-proof valve film because the air pressures inside the batteries are too high, ensuring that the outer sizes of the batteries are not changed, and being beneficial to integrally assembling battery packs.

Description

technical field [0001] The invention belongs to the technical field of power lithium battery manufacturing, and in particular relates to a battery deflation device and a use method thereof. Background technique [0002] The electric vehicle uses the power battery to provide electric energy for the driving motor of the electric vehicle. The electric motor converts the electric energy of the power supply into mechanical energy, and drives the wheels and working devices through the transmission device or directly. Electric vehicles themselves do not emit harmful gases that pollute the atmosphere, which is conducive to saving oil and reducing emissions, reducing greenhouse gas emissions and purifying air quality. Therefore, they are popular with the public and are the future development trend of automobiles. During the use of the battery, a small amount of gas will be continuously produced, which will cause the internal pressure to increase and cause the risk of rupture. [000...

AI Technical Summary

Problems solved by technology

However, this patent only solves the problem of battery safety, and cannot prevent the battery from rupture due to excessive internal pressure. Now the battery module contains multiple battery cells. If one battery cell is scrapped, the entire module must be replaced. group, causing great waste, so the possibility of scrapping due to battery rupture must be reduced
