Abstract

The invention provides a vehicle thermal management method and device, a vehicle and a storage medium. The method comprises the steps of acquiring vehicle working condition data and vehicle driving environment data; analyzing the vehicle working condition data and the vehicle driving environment data to obtain battery temperature data; and adjusting and controlling parameters of equipment in a cooling system by adopting a preset strategy according to battery temperature data. According to the invention, since the future battery temperature is predicted by combining the vehicle working condition data and the vehicle driving environment data, prospective prediction of the battery temperature is realized, the thermal management of the vehicle is realized according to the predicted battery temperature data, and the active vehicle thermal management is realized; and thermal management precision and thermal management efficiency can be effectively improved, and a thermal management effect iseffectively increased.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a vehicle heat management method, device, vehicle and storage medium. Background technique [0002] The power battery system is the core component of an electric vehicle. Temperature has an important impact on the performance and life of the power battery system. Therefore, the power battery system will be equipped with a thermal management system. Based on the thermal management system, the power battery temperature can be controlled to ensure power. Temperature uniformity within the battery pack. [0003] In related technologies, the thermal management system usually uses temperature sensors to obtain parameters such as state of charge and current of the battery, and predicts the battery temperature based on these parameters, so as to realize timely and forward-looking thermal management control. [0004] In this way, only passive vehicle thermal management is perform...
