Title:
METHOD AND APPARATUS FOR CONTROLLING HEAT DISTRIBUTION OF ELECTRIC VEHICLE, STORAGE MEDIUM, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/066359
Kind Code:
A1
Abstract:
A method and apparatus for controlling heat distribution of an electric vehicle, a storage medium, and a device. The method comprises: acquiring oil temperature values uploaded by oil temperature sensors and a battery temperature value uploaded by a battery management device (S102), wherein the oil temperature values comprise a first oil temperature value and a second oil temperature value, the first oil temperature value is an oil temperature value measured by a first oil temperature sensor installed on a first electric oil pump, and the second oil temperature value is an oil temperature value measured by a second oil temperature sensor installed on a second electric oil pump; determining a control mode on the basis of the oil temperature values and the battery temperature value (S104), the control mode being used for determining the position of a valve core of a three-way valve in an oil path of a target vehicle; determining rotational speeds of the electric oil pumps on the basis of the oil temperature values (S106); and completing heat distribution on the basis of the control mode and the rotational speeds (S108). The present disclosure solves the technical problem that existing heat distribution systems for power assemblies of electric vehicles are low in overall efficiency and high in power consumption and thus affect low-temperature driving ranges of the vehicles.
