Abstract

The invention relates to an energy-saving range-extending PHEV heat management system, and relates to the technical field of electric automobiles. The energy-saving range-extending PHEV heat management system comprises a battery circulation pipeline, a range extender circulation pipeline, a switching device, a motor circulation pipeline and a controller. The battery circulation pipeline comprises a battery pack; the range extender circulation pipeline comprises a range extender and is connected with the battery circulation pipeline through a battery cooler; the switching device is arranged on the range extender circulation pipeline and is used for connecting and disconnecting the range extender circulation pipeline and the battery cooler; the motor circulation pipeline comprises a motor and is connected with the battery circulation pipeline through a first control valve; and the controller is connected with the switching device and the first control valve, and is used for controlling the switching device to connect or disconnect the range extender circulation pipeline and the battery cooler according to the environment temperature, and controlling the on-off of the first control valve, so that the waste heat of the range extender or the motor is utilized to heat the battery pack. The battery pack can be heated by fully utilizing the heat of the range extender and the heat of the motor according to the environment temperature, and meanwhile PTC intervention is reduced.

Description

technical field [0001] The present application relates to the technical field of electric vehicles, in particular to an energy-saving extended-range PHEV thermal management system. Background technique [0002] At present, with the continuous tightening of national fuel consumption and emission regulations, more and more OEMs are devoting themselves to the development of electric vehicles. For plug-in hybrid electric vehicle PHEV, the battery will have low charge and discharge efficiency in low temperature environments. , which greatly affects the cruising range and life of the battery. Therefore, thermal management is required to solve the problem of battery insulation in a low temperature environment, so that the battery can maintain its normal operating temperature between 10°C and 25°C. [0003] In related technologies, PTC is generally used to heat the battery, but this solution first needs to consume battery power. When the car is cold started in a low temperature envi...
