What does the 48V mild hybrid system mean? Is it considered new energy?
2 Answers
48V mild hybrid systems are not classified as new energy vehicles in mechanical terms, as they cannot independently provide electrical power to enable pure electric driving. The electrical energy is only used to assist vehicle propulsion during daily operation. The principle of the 48V hybrid system is quite simple: it upgrades the traditional 12V electrical system to 48V and incorporates components such as electric motors and battery packs, enabling it to assist in vehicle propulsion and store/recover electrical energy. Below are the advantages of the 48V mild hybrid system: 1. Preventing battery drain: Vehicles equipped with a 48V mild hybrid system feature a higher-capacity battery, making it possible to listen to music with the engine off and use more onboard electronics without worry. The system will start the engine when the battery is about to run out, preventing battery drain. 2. Technology: The advanced powertrain technologies associated with 48V mild hybrid vehicles not only ensure strong performance but also deliver excellent fuel efficiency, making them worthy of further promotion.
A 48V mild hybrid system refers to a small hybrid system that uses a 48-volt battery to assist the engine, such as stopping the engine during start-stop, providing extra power during acceleration, and recovering braking energy to generate electricity. It is not a true new energy system; new energy vehicles must rely entirely on electricity or plug-in hybrids capable of long-distance electric-only driving. In contrast, the 48V system has a small battery, with the engine still being the main power source—it only saves some fuel and improves smoothness. I've driven several cars with this feature and noticed it's much quieter in traffic, with fuel consumption reduced by about 10%. However, you still need to refuel, unlike pure electric cars that save money and are more eco-friendly when charging. Technically speaking, it's just a transitional aid, allowing automakers to quickly achieve energy savings without changing the essence of traditional powertrains. Overall, it's practical but don’t expect it to qualify for green license plates or exemption from purchase taxes.
