Problems solved by technology
When the external circulation is turned on, the air outside the vehicle is heated by the PTC heater and then input into the vehicle for heating. However, the PTC heater is directly powered by the power battery pack, which consumes a lot of energy. In actual use, the electric vehicle continues to drive after the heater is turned on. Mileage will be greatly reduced
When used in winter, the heated air comes from the external space of the vehicle, and the temperature outside the vehicle is low in winter. The PTC heater has the characteristic that the lower the ambient temperature, the higher the energy consumption. Using low-temperature air for heating has low efficiency and high energy consumption.
The vehicle heating system has low efficiency and high energy consumption, and the energy utilization rate of electric vehicles is also low

The invention discloses an energy-saving type heating system of an electric automobile, which is characterized by comprising an air blower; a warm air system control device; an in-vehicle temperaturesensor; a PTC heater control device; a PTC heater; an internal and external circulation air door actuator; a hybrid damper actuator; a waste heat air door actuator; a waste heat input air duct; an internal circulation air duct; and an outer circulation air duct. The space where the PTC heater is located communicates with the space where an automobile power system is located through the waste heatinput air duct. After the air blower is started, air coming from the space where an automobile power system is located enters the space where the PTC heater is located through the waste heat input airduct and then is input into the internal space of an automobile compartment through the space where the PTC heater is located. After the warm air system is started, waste heat generated by the electric automobile power system is combined with the PTC heater to supply warm air to the inner space of the automobile compartment, the efficiency of the electric automobile warm air system is improved, energy consumption is reduced, and the driving range of the electric automobile can be prolonged when the electric automobile is used in a low-temperature environment.
Description
technical field [0001] The invention relates to the field of on-board systems for electric vehicles, in particular to an energy-saving heater system for electric vehicles. Background technique [0002] For most traditional fuel vehicles, the heat of the heating system comes directly from the engine, while the heat generated by the power system of an electric vehicle when it is stopped or running at a low speed is not enough to directly provide the heat source required by the heating system. [0003] At present, electric vehicles generally use PTC heaters as the heating method of the heating system. When the external circulation is turned on, the air outside the car is extracted and heated by the PTC heater and then fed into the car for heating. However, the PTC heater is directly powered by the power battery pack, and the energy consumption is high. In actual use, the electric vehicle continues to drive after the heater is turned on. Mileage will be drastically reduced. Wh...
