What is the meaning of "Feng Shui" in the gas valve?

There are two kinds of hybrid oil and electricity.

Standard hybrid: You can charge the battery while driving.

Plug-in hybrid: consumes battery power and basically does not charge.

Let's take Toyota's Ralink dual-engine hybrid electric vehicle as an example. In the sliding stage of the car, the driving motor is converted into a generator, and the kinetic energy is converted into electric energy to charge the car battery. Lei Ling battery has a cruising range of 40 kilometers, but it has the ability to charge, so as long as the battery shows normal, it doesn't need to be charged at any time.

For plug-in hybrid, such as Changan Ford Mondeo 20 18 plug-in hybrid, because the drive motor does not have the ability to charge the battery, the battery has been in a state of consumption, so it needs to be charged almost every time before going out.
