Abstract

The invention provides a battery heating system detection method and device, a vehicle and a storage medium. The battery heating system detection method comprises the following steps of: at a first moment when a battery pack is in a heating state, acquiring a first temperature value of a single battery with the highest temperature in the battery pack; acquiring a second temperature value of the single battery with the highest temperature in the battery pack at a second moment which is spaced from the first moment by preset duration; according to the first temperature value and the second temperature value, determining a temperature change parameter value of the battery pack within the preset duration; and determining whether the heating performance of a battery heating system is normal or not according to a magnitude relationship between the temperature change parameter value and a first preset threshold value. According to the battery heating system detection method, whether the heating performance of the battery heating system is normal or not is determined by monitoring the temperature value of the battery pack in the heating process in real time, the performance problem of the heating system can be found in the first time, related workers can remove faults of the battery heating system in time, and therefore it is guaranteed that the battery pack is safely used in the low-temperature environment.

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...
