Abstract

The invention relates to the technical field of battery tests, in particular to a system and method used for a seawater immersion test of a power battery pack. The system comprises an immersion box, and a hydrometer and a pH tester are mounted on the immersion box and placed under a liquid surface of a test solution; the system further comprises a thermostat, a circulation pump, a movable hoistingframe and a lifting hoisting head; the pH value and specific gravity value of the test solution are adjusted before the test by the hydrometer and the PH tester so as to be more proximate to those ofseawater; at the same time, the temperature of the test solution in the immersion box is adjusted by the thermostat and the circulation pump so that the temperature of the test solution in the immersion box can be stabilized, the test solution can also stay in a flowing state, a seawater flowing state is further simulated, and the sealing performance of the power battery pack in the state that the power battery pack is driven by flowing liquid is tested to enhance the accuracy and reliability of a test result.

Description

technical field [0001] The invention relates to the technical field of battery testing devices, in particular to a system and method for seawater immersion testing of power battery packs. Background technique [0002] With the rapid development of automobile technology, the dominance of new energy vehicles has become increasingly prominent. The outstanding advantages of low cost, superior performance, and high controllability are popular with everyone. As a key internal component of new energy vehicles, battery packs have also attracted more and more attention. Performance such as safety and reliability cannot be ignored. Our company focuses on battery packs. Design a series of test contents to ensure the quality of battery pack products, among which seawater immersion is one of the main tests to verify the sealing, safety and reliability of battery packs. At present, there is no special equipment on the market to simulate seawater to test the accuracy and accuracy of batter...
