What is?
is in the extended-range electric car on the basis of pure electric vehicles, equipped with a small auxiliary generator set is insufficient to prepare battery, by the engine to charge the battery. Directly driven by the motor vehicle, the engine is not involved in the drive.

[ 123] Did you know?
extended-range electric vehicle is not involved in the internal combustion engine drive the car under its own power, the role of the internal combustion engine is only driven generator to charge the battery pack, so even if the situation did not appear electric car , that does not break down, it can rely on the engine power to drive the car.
3 [ 123] advantages:
have a long-mileage, the engine can be used when charging the battery is low.
· directly driven by the motor, and electric vehicles as large torque force directly accelerated fast.
· wider range, can meet the daily use of a charging means of the charging apparatus, but also to provide a longer continuous adding fuel chargeAir mileage, meet out of town.
· light rechargeable battery can charge and discharge shallow discharge, is conducive to battery life.
simple
· structure, direct drive motor, easy maintenance, easy to realize industrialization.

[ 123] principle:
extended-electric vehicles, only one set of internal power drive system includes a motor, a control circuit, a battery. Direct motor drives 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 the one loaded in the ordinary gasoline pure electric vehicles / diesel generator.

extended-range electric car at high speed traffic, high fuel consumption. 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. The representatives of this type of model BMW i3 extended-range version, the Chevrolet Volt and so on.
