Abstract

The invention discloses a vehicle power system temperature control device and a control method thereof. The device comprises a water pump (3), a cooled device (5), a cooling fan (7), a radiator (8) and a pipeline (9). The cooling fan is installed on the radiator, and the water pump and the radiator form a coolant circulation structure through the pipeline, so that the coolant flows through the cooled device; it also includes a first temperature sensor (2), a controller (4) and a second temperature sensor (6), the first temperature sensor is set on the water outlet of the radiator, the second temperature sensor is set on the device to be cooled, the output ends of the first temperature sensor and the second temperature sensor are connected to the input end of the controller, and the controller The output end of the control circuit is connected with the control end of the water pump and the cooling fan. The invention can adjust the power of the water pump and the fan in real time according to the driving state of the vehicle and the temperature of the power system, greatly reduce the energy consumption of the system on the basis of meeting the heat dissipation requirements, and prolong the driving range of the pure electric vehicle.

Description

technical field [0001] The invention relates to a vehicle power system, in particular to a vehicle power system temperature control device and a control method thereof. Background technique [0002] At present, the power system cooling device used in automobiles uses a liquid-cooled circulation system to control the temperature. The liquid-cooled circulation system drives the coolant by a water pump. When the coolant carries heat through the radiator, the cooling fan drives the outside air to flow through the radiator blades and Take away the heat of the coolant, so as to achieve the purpose of cooling. [0003] The water pumps and cooling fans used in pure electric vehicles are driven by electricity. The water pumps usually use switch-type water pumps. After the vehicle is powered on, the water pumps will run at rated power. When the vehicle's operating load is low and the outside temperature is low, the heat dissipation requirements of the power system are low, and the fa...
