Description
Technical field
The present invention relates to new-energy automobile field more particularly to the heating methods of a kind of electric vehicle and electric vehicle.
Background technology
Energy conservation and environmental protection is the theme that the world today advocates jointly, and New-energy electric vehicle will become future automobile industry development
Inexorable trend.As one kind, easily walking-replacing tool, riding comfort are also key factor to automobile.New-energy electric vehicle
Engine is eliminated, for the waste heat of engine coolant as heat source, automobile cab heating is not that a prodigious technology is chosen
War.In addition, New-energy electric vehicle, under the conditions of microthermal climate, battery repid discharge, power reservoir capacity is lost, battery life
Shorten, this is also that New-energy electric vehicle uses and develop limited one of reason.
The heating in New-energy electric vehicle field is based on electricity auxiliary heating at present, in addition to this, also fuel Heating side
Formula and heat pump mode.
The principle of electricity auxiliary heating is that the heater in heater is Resistant heating pipe or PTC heating tubes, to heater
In air heated, the heat in heater is sent into heater cores using recirculated water as medium, is finally blown into warm wind and drives
Sail room.This mode operability is strong, technology relative maturity, but heating power is big, in 3000W or more, battery capacity consumption
It is huge, seriously affect the course continuation mileage of automobile and the service life of battery.
The principle of fuel Heating is that the heater in heater is the fuel oil being atomized, and spark plug lights fuel oil, pair plus
Air in hot device is heated, and the heat in heater is sent into heater cores using recirculated water as medium, is blown into driver's cabin.It should
Mode fuel consumption generates exhaust emissions, is disagreed with the zero-emission theory of New-energy electric vehicle；Fuel heating system structure
Complexity, amount of parts is more, considerably increases technical difficulty and cost, production operation is complicated, reduces the reality of electric vehicle
With property, increase car body weight, reduces course continuation mileage.
The principle of heat pump is to increase solenoid valve control refrigerant stream on the basis of motor compressor refrigerating circuit
To, heat is absorbed from ambient enviroment by evaporative condenser, by internal condensation device to driver's cabin discharge heat.Heat pump system
Complicated, amount of parts is more, and Arrangement of Engine-room is difficult, and technical difficulty is very big, and development cost is very high, reduces electric vehicle
Practicability.
The electricity auxiliary heating heating mode that New-energy electric vehicle mainly uses on existing market, high energy consumption are serious to reduce
Automobile course continuation mileage reduces battery；There are the critical defects of exhaust emissions for fuel Heating heating mode, and and heat pump
Heating service mode is the same, complicated, parts are more, technical difficulty is big, of high cost, seriously reduces New-energy electric vehicle
Practicability.In addition, three of the above heating mode can also cause the defect that in-car air quality is poor, dry, noise is big simultaneously, drop
Low comfort by bus affects in-car air quality and health.
