What is the introduction to the gears of new energy automatic transmission vehicles?

Electric vehicle gears: Introduction to automatic transmission gears. The typical gears on an automatic transmission vehicle are: P (Park), R (Reverse), N (Neutral), D (Drive), D1; 2; 3; M+; -; (Limited gears), L (Low gear), S (Sport mode). Below is a detailed introduction to electric vehicles: Concept: Electric vehicles (BEV) refer to vehicles that use on-board power sources as their driving force, with electric motors driving the wheels, meeting all the requirements of road traffic and safety regulations. They are powered by electricity stored in batteries. Sometimes 12 or 24 batteries are used to drive the vehicle, and sometimes more are needed. Types: The types of electric vehicles include pure electric vehicles (BEV), hybrid electric vehicles (HEV), and fuel cell electric vehicles (FCEV). Power source: Provides electrical energy to the driving motor of the electric vehicle, which converts the electrical energy into mechanical energy. The most widely used power source is lead-acid batteries, but with the advancement of electric vehicle technology, lead-acid batteries are gradually being replaced by other types of batteries due to their low energy density, slow charging speed, and short lifespan. The power sources currently under development mainly include sodium-sulfur batteries, nickel-cadmium batteries, lithium batteries, fuel cells, and other new power sources.
I recently drove a new energy vehicle and realized how smart the gear settings are. The main ones are P for Park, R for Reverse, N for Neutral, and D for Drive, which are pretty much the same as traditional cars. However, new energy vehicles have an additional B gear or similar, mainly used to increase regenerative braking. For example, when going downhill, shifting to B gear can automatically slow the car down while also recovering electrical energy, saving both brake pads and being eco-friendly. Sometimes you can also switch driving modes, like Eco for energy saving or Sport for faster acceleration—it feels like a high-tech toy. Using it is simple: start by shifting to D gear to get moving, and immediately shift to P gear when parking to prevent rolling. Before switching to R gear for reversing, make sure the car is completely stopped. If you forget to shift to P gear, the car will automatically remind you or lock itself to prevent accidents. I think these designs are not only safe but also really cool, especially suitable for saving energy in city traffic jams.
