Range extender refers to the electric vehicle parts that can provide additional electric energy, so that the electric vehicle can increase the driving range.

In short, the range increaser is the combination of engine and motor. Compared with other new energy vehicles, the incremental electric vehicle has a simple configuration system. More importantly, it has more reliable performance and less cost.

Compared with electric vehicles, the plug-in electric vehicles do not have to worry about the car's range, and can reduce the cost of car use. The range extender used in electric vehicles generally uses an internal combustion engine to drive a generator to charge the battery to increase the driving range.

Lohner Porsche, as the ancestor of hybrid vehicles, its engine+generator combination just meets the definition of range extender. The range extender charges the battery, and the battery drives the hub motor, which can be called the purest "series type".
