Specifically, in the cooling mode, the actual temperature is subtracted from the first temperature value to obtain a temperature difference value corresponding to the cooling liquid in the thermal management system, if the temperature difference value is greater than a preset temperature difference value, the temperature of the cooling liquid is higher, that is, the temperature of the battery is higher, and the battery needs to be cooled rapidly at this time, so that the rotating speed of the compressor needs to be increased, that is, the rotating speed of the compressor is adjusted to be a first rotating speed to realize rapid cooling of the battery, and if the temperature difference value is less than or equal to the preset temperature difference value, the smaller rotating speed of the compressor can realize cooling treatment of the battery at this time, and in order to reduce energy consumption of the compressor, the rotating speed of the compressor in the cooling mode needs to be adjusted to be a second rotating speed.
Further, if the actual temperature is less than or equal to the fourth preset temperature value, it is determined that the temperature of the battery pack is good and is in a safe state, and in order to save energy consumption of the thermal management system, the purpose of controlling the battery temperature can be achieved by only starting the circulating pump at this time, so that the next working mode of the thermal management system is determined to be a self-circulation mode, namely, the circulating pump is in a starting state, but the compressor is in a closing state.
Further, if the actual temperature is greater than the fourth preset temperature value and less than the first temperature value, in order to save the energy consumption of the thermal management system, the next working mode of the thermal management system needs to be determined based on the current working mode of the thermal management system, and based on this, the method includes: if the current working mode is a standby mode or a self-circulation mode, determining that the next working mode of the thermal management system is the self-circulation mode; and if the current working mode is a refrigeration mode, determining that the next working mode of the thermal management system is the refrigeration mode.
Specifically, if the actual temperature is greater than the fourth preset temperature value and less than the first temperature value, determining a current working mode of the thermal management system, if the current working mode is a standby mode or a self-circulation mode, based on the self-circulation mode, cooling treatment of the battery can be achieved, determining a next working mode of the thermal management system as the self-circulation mode, and if the current working mode is a refrigeration mode, determining the next working mode of the thermal management system as the refrigeration mode in order to avoid energy consumption caused by continuously switching the working modes.
