1, the gasoline-electric dual-purpose vehicle is a simple motorcycle engine and drive device directly grafted on the electric vehicle;
2. Technically, the battery-driven motor and the mechanical drive are simply connected in parallel; Therefore, there are many technical defects; Throttle control is to control the engine by turning the cable; At the same time, the electric knob (Hall handle) controls the rotating speed of the motor (hub); When two modes * * * work together; Unable to achieve speed synchronization; It led to the failure of electric vehicle electrical system damage, so it quickly withdrew from the market.
3. Extended range electric vehicle (with national patent); The basic principles are: A. The engine directly drives the generator, and the electric energy generated by the generator is provided to the electric vehicle through technical treatment; B. The real-time power generation (power) of the generator is controlled by the on-board computer system; C, the extended-range electric vehicle has no mechanical transmission transposition at all;
4. "It's far away from home, and you have to push the car back when the battery is dead" is the biggest pain point in the use of electric vehicles. The technical maturity and listing of extended-range electric vehicles have opened up the prospect of continuous progress and development of electric vehicles, and provided a brand-new choice of personal transportation tools for the 200 million Volkswagen electric vehicle users in China.
