1. A method for cooling a passenger compartment and a battery, comprising:
determining a current driving phase of a vehicle;
querying a target cooling strategy corresponding to the current driving phase of the vehicle according to a corresponding relationship between a driving phase and a cooling strategy, wherein different driving phases correspond to different cooling strategies, and each of the cooling strategies comprises cooling the passenger compartment and cooling the battery; and
cooling the passenger compartment and/or the battery according to the target cooling strategy;
wherein the driving phase comprises an operation phase, and cooling the passenger compartment and/or the battery according to the target cooling strategy comprises:
prioritizing to cool the passenger compartment according to the target cooling strategy corresponding to the operation phase until the current temperature of the battery exceeds a preset third temperature threshold of the battery, and then switching to only cool the battery;
wherein in a process of cooling the passenger compartment, the method further comprises:
determining whether the current temperature of the battery exceeds the third temperature threshold of the battery;
on the condition that the current temperature of the battery does not exceed the third temperature threshold of the battery, querying a target required inlet water temperature of the battery corresponding to the current temperature of the battery according to a corresponding relationship between a temperature of the battery and a required inlet water temperature of the battery, and cooling the battery according to the target required inlet water temperature of the battery and remaining the current temperature of the passenger compartment not exceeding a preset third temperature threshold of the passenger compartment at the same time, wherein different temperature intervals of the battery corresponding to different required inlet water temperatures of the battery.
