Problems solved by technology

[0003] Publication number CN109752659A discloses a liquid-cooled battery PACK test system and method, and invented a liquid-cooled battery PACK test system and method in the charging and discharging state. The thermal parameters are only detected based on temperature data. The parameters are relatively single, the accuracy and precision of the detection cannot be guaranteed, and the heat flux parameters that change rapidly are not involved, so the thermal safety of the battery system cannot be scientifically evaluated

The invention further provides a detection and evaluation method based on the mobile power batterythermal management system detection device to evaluate the thermal safety of the power battery.

Description

technical field [0001] The invention belongs to the technical field of power battery thermal characteristic testing, and in particular relates to a detection device and method for a mobile power battery thermal management system. Background technique [0002] With the continuous expansion of the use of power batteries, the thermal runaway detection technology of power batteries needs to be further improved. Especially in electric vehicles, the use environment of lithium-ion batteries is very complex and harsh, so it is necessary to establish a more scientific quantitative testing and evaluation method. especially urgent. [0003] Publication number CN109752659A discloses a liquid-cooled battery PACK test system and method, and invented a liquid-cooled battery PACK test system and method in the charging and discharging state. The thermal parameters are only detected based on temperature data. The parameters are relatively single, and the accuracy and precision of the detecti...
