Electric vehicle remote thermal management control method, device and system and storage medium

Abstract

The invention discloses an electric vehicle remote thermal management control method, device and system and a storage medium. The method comprises: acquiring a vehicle reservation instruction which issent by a user side and comprises reservation information such as estimated departure time, an estimated destination position and an estimated driving mode; based on the reservation information and the obtained current parking point position, determining a predicted environment temperature and a predicted driving duration of the to-be-used vehicle in the travel; determining a current thermal management mode and a current battery target temperature based on the predicted driving mode, the predicted environment temperature and the predicted driving duration; determining current thermal management starting time and current thermal management starting duration based on the estimated departure time; and controlling a heat pump system of the to-be-used vehicle to perform heat management on theto-be-used vehicle through the power domain controller according to the determined heat management control information. By adopting the embodiment of the invention, unnecessary energy waste can be reduced while the use comfort of the vehicle is improved and the cruising ability of the vehicle is increased.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a remote thermal management control method, device, system and storage medium of an electric vehicle. Background technique [0002] With the ever-increasing contradiction between energy demand and environmental pollution and resource shortage in the development of human society, electric vehicles with advantages of economy and environmental protection have become the means of transportation chosen by more and more people. With the continuous improvement of people's requirements for vehicle power, economy and comfort, thermal management of electric vehicles has become a must. [0003] At present, in the thermal management of electric vehicles, when it is judged that the battery temperature is at the limit, the energy of the charging pile is used to perform thermal management on the battery of the electric vehicle in advance, so that the temperature of the battery reaches a fixed ...

Problems solved by technology

[0004] However, the inventor found in the process of implementing the present invention that during the driving of the electric vehicle, the driving mode is an important factor determining the minimum operating temperature of the battery, and the ambient temperature and driving time are important factors affecting the temperature change of the battery. In this method, the target temperature for thermal management of the battery is fixed, and the influence of factors such as the ambient temperature, driving time, and driving mode in each trip is not considered, and it is easy to heat or cool the battery too much. situation, thereby wasting unnecessary energy
