Hybrid type of electric vehicle
- Aug 22, 2018 -

Hybrid electric vehicles can use a fuel-engined engine to operate at a high-efficiency operating point to charge the battery, while an electric drive system is used to cope with changing operating conditions. The hybrid type we divide it into two categories.

First, parallel hybrid

In a parallel hybrid (also known as power assisted) configuration, the hybrid unit is directly mechanically coupled to the wheel (this is similar to a conventional car), but the motor can also drive the wheel. For example, a parallel hybrid vehicle can use the power generated by the internal combustion engine while driving on a highway, and the power of the motor is used for acceleration. One of the benefits of the parallel configuration compared to the series configuration is that the electric car has more power (because the engine and the motor can simultaneously provide power), most parallel hybrid cars do not require a generator, and the power is directly on the road. Coupling is therefore more efficient.

Second, the series hybrid

There is no mechanical connection between the series hybrid power unit and the wheels, so all power is converted into electrical energy to the motor that drives the wheels. The advantage of the series configuration compared to the parallel configuration is that engine idle speed is eliminated, thereby reducing emissions. The engine-driven generator operates in the best performance zone, and the engine and other components can be arranged in a variety of ways. Some tandem hybrid electric vehicles do not even require a transmission.

Hybrid electric vehicles are more economical and more environmentally friendly.
