The drive mode refers to the form of the car power source into electric, extended range, plug-in hybrid, non-plug-in hybrid four. .
1. Term interpretation drive mode
Pacific Automotive Network currently has for new energy vehicles in the automotive division and classification Daquan reference page with the following categories:
[ 123] are the pure electric vehicles, extended-electric vehicles, plug-in hybrid and a non-plug-in hybrid.
1 electric vehicle: means equipped with only battery power, the vehicle driven by a motor. .
2 by electric car program: refers to an external charging power source and the vehicle charging, the vehicle driven by a motor. .
3 plug-in hybrid: a hybrid vehicle capable of charging external power source.
Non-plug-in hybrid 4: external charging power source is not a hybrid vehicle.
extended-electric vehicles and electric vehicles belonging to the category of electric vehicles, plug-in hybrid and the non-insertedElectric hybrid is a hybrid of one classification.
Electric Vehicle: refers to one or more sources of power equipment, motor vehicles driven wheels (including the extended-electric vehicles).
Hybrid vapor: means while the vehicle is equipped with two or more sources of power, and electric drives using the engine driving both driving automobiles.
2. pure electric vehicles
pure electric vehicles refers to the vehicle power supply as a driving force, with a motor-driven wheel driving, in line with road traffic vehicles, the requirements of safety regulations. The environmental impact of conventional cars is relatively small, it is widely optimistic outlook, but current technology is not yet mature.
pure electric vehicles (Battery Electric Vehicle, referred to as a BEV), which is completely powered by a rechargeable battery source (e.g., lead-acid batteries, nickel cadmium battery, a nickel hydride battery or a lithium ion battery) car. Although it has been 134 years of history, but within a certain range of applications has been limited to smaller markets. Mainly due to various types of batteries, the prevalence of high price, short life and large dimensions and weight, a long charging time serious drawbacks.
3. Car by program
alone electrical generator with cars, the power output of the engine is only disposed for pushing generators. System output power equal to the motor output power.
this type of model, strictly speaking, is still electric vehicles. Only a vehicle electric drive system includes a motor, a control circuit, a battery. Extended range of plug-in hybrid motors directly driving the wheels, the engine is used to drive a generator to charge the battery. Since the engine does not directly drive the wheels, and therefore does not need the transmission. This is equivalent to an ordinary electric vehicle loaded with a petrol / diesel generators.
Advantages:
1 quiet an electric vehicle, a great advantage breakaway torque, can be a pure electric vehicle use, convenient charging under the conditions of charging only, without refueling, low cost;.
2 compared to other hybrid mode, range-extended hybrid transmission can not, slightly lower cost. Due to an engine with power, as long as you can always run down gas station, where convenient charging of the trailer will not be forced to address the shortage of infrastructure problems;
3 because the engine does not directly. driving wheels, engine speed and wheel speed, vehicle speed is not directly related to optimization by the control system, allowing the engine has been working at optimum speed, even when the charging inconvenience, fuel under city traffic jam is relatively low, the engine noise can be control is very small.
Disadvantages:
1 resulting in wasted power. Since the engine and the generator do not directly drive the wheels, resulting inThis part of the waste power of the generator and the engine, and brings the weight does not reduce.
2. In a road at high speed, but high fuel consumption. This is because the high-speed road, if the engine drives the wheels directly, you can always work in the best mode, and extended-range plug-in hybrid one more conversion process, the conversion itself to consume energy, resulting in higher fuel consumption instead.
4. The hybrid vehicle
according to whether the external charging power characteristics classification, including plug-in hybrid and a non-plug-in hybrid two kinds.
Plug-in hybrid and the non-plug-in hybrid distinction
The plug-in hybrid (Plug-in Hybrid Vehicle, referred PHV), it simply is interposed between the electric vehicle and a vehicle between the two fuel vehicles. He both traditional car’s engine, transmission, drivetrain, fuel lines, tanks, there are electric car batteries, motors, control circuit. And the battery capacity is relatively large, the charging interface.
compared to the kinds of non-plug-in hybrid vehicles, plug-in hybrid car batteries larger capacity, can support more miles traveled . If short trips each time, better charging conditions, the battery plug-in hybrid car can be without refueling, as the use of pure electric vehicles, electric vehicles have advantages.
Non-plug-in hybrid must fuel, driven by the engine powerMachine to charge the battery, the engine drives the wheels directly, or with both the motor and also the engine together drive the wheels.
