Problems solved by technology

This patent document uses liquid purging. When the battery assembly coolant inlet and outlet pipes are removed after the test, a large amount of coolant remaining in the pipes is easy to gushes out, and the gushing coolant remains on the ground. On the one hand, it brings 6S management pressure. It is inconvenient, on the other hand, the coolant has certain toxicity, and long-term exposure will endanger human health; in addition, the coolant that gushes out will be polluted and cannot be reused, and it is troublesome to recycle, which increases the processing cost

Abstract

The invention discloses a coolant purging device for battery assembly testing. The coolant purging device comprises a battery assembly, a compressed gas control unit for purging the coolant and a liquid storage unit for recovering and circulating the coolant, wherein the battery assembly and the liquid storage unit are connected through a coolant outlet pipe and a coolant inlet pipe and the compressed gas control unit is connected with the coolant inlet pipe. The invention also discloses a coolant purging method for battery assembly testing. With application of the coolant purging device and purging method for battery assembly testing, the gas purging function can be realized, the purging efficiency is high and the purging effect is better.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a cooling liquid purge device and a purge method for battery assembly testing. Background technique [0002] In recent years, with the promotion of national policies on energy conservation, emission reduction and development of clean energy, electric vehicles have developed rapidly. As the energy storage element of the electric vehicle, the performance of the power battery directly affects the performance of the electric vehicle. In the vehicle working mode, when the temperature of the external environment and the battery assembly is high or low, the cooling / heating system will cool down or heat up the battery assembly, so as to ensure that its performance will not be greatly affected. In order to truly simulate the working environment of the battery assembly in the real vehicle state, when testing the performance of the battery assembly in the laboratory, it is necessar...
