Problems solved by technology

However, the inside of the battery system may also be soaked by coolant. Most power battery systems have liquid-cooled thermal management systems inside. Therefore, it is necessary to propose a test and evaluation method for the leakage of coolant in the power battery system to verify whether the battery system can meet the safety requirements when the coolant enters the battery box, so as to ensure the safety of the driver
[0004] However, the existing tests on the coolant leakage of the power battery system still have shortcomings such as the testing process is not comprehensive enough.

Abstract

The invention discloses a power battery test system and method, and the system comprises a test tool which is installed in a cooling pipeline corresponding to a target test part in a power battery system, and comprises a plurality of jet holes communicated with the cooling pipeline and a control valve for controlling the opening and closing of the plurality of jet holes, wherein the plurality of jet holes face the target test part, and the jet angles of the plurality of jet holes are not completely the same; and an upper computer which is connected with the control valve and the power battery pack, and is used for controlling the control valve to be opened, so that the cooling liquid in the cooling pipeline is sprayed to the target test part through the plurality of jet holes, a cooling liquid leakage scene is simulated, and the performance parameters of the power battery pack in a cooling liquid leakage scene are obtained. According to the system, the more comprehensive safety evaluation on the performance parameters of the power battery pack can be realized in the cooling liquid leakage scene of the power battery system.

Description

Technical field [0001] The present invention relates to a vehicle safety testing technology, and particularly relates to a power battery testing system and method. Background technique [0002] With the new energy vehicles promotion and application of lithium-ion batteries used in electric vehicles has become a trend. Security issues battery power system is one of the important technical issues that affect the development of new energy vehicles, it is not only related to the chemical system of batteries, battery systems, security design, is also associated with failure of new energy vehicles in the course of the scene.
