Abstract

The present application provides a battery heating system detection method, device, vehicle and storage medium. The method includes: at a first moment when the battery pack is in a heating state, obtaining a first temperature value of the battery cell with the highest temperature in the battery pack; The second temperature value of the battery cell with the highest temperature among them; according to the first temperature value and the second temperature value, determine the temperature change parameter value of the battery pack within the preset time period; according to the temperature change parameter value and the first preset threshold value Size relationship, to determine whether the heating performance of the battery heating system is normal. This method monitors the temperature value of the battery pack during heating in real time to determine whether the heating performance of the battery heating system is normal, and can detect the performance problem of the heating system at the first time, so that relevant staff can promptly troubleshoot the battery heating system, thereby ensuring Safe use of battery packs in low temperature environments.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a detection method and device for a battery heating system, a vehicle and a storage medium. Background technique [0002] As a mobile energy carrier, the power lithium-ion battery is the core component of new energy equipment, and it continues to play a pivotal role in changing people's intelligent lifestyle. However, limited by the characteristics and technological development of lithium-ion batteries, the current performance of lithium-ion batteries in low-temperature environments cannot fully meet the conventional needs, and abnormal use at low temperatures may even cause safety problems. The main solution is to heat the batteries to a suitable temperature. temperature to start use. For example, when the lithium-ion battery of a new energy vehicle is in a low-temperature environment, in order to avoid abnormalities during use, the battery needs to be heated to an a...
