What is the range-extending principle of the Li ONE?
2 Answers
The range-extending principle of the Li ONE is that the engine is responsible for power generation, and there is no direct connection between the engine and wheel drive. Here are the specific details of the Li ONE: 1. Powertrain: The Li ONE is equipped with a 1.2T turbocharged engine. In terms of the transmission system, it uses a single-speed electric vehicle transmission, with a maximum power output of 96 kW and a maximum horsepower of 131 hp. 2. Dimensions: The Li ONE has a body length of 5020 mm, width of 1960 mm, height of 1760 mm, and a wheelbase of 2935 mm. 3. Suspension: The Li ONE features a dual-motor all-wheel-drive system, with a front MacPherson independent suspension and a rear multi-link independent suspension. The body structure is a unibody design.
I've been studying vehicle powertrain systems and am very familiar with the range-extending principle of the Li ONE. It's essentially an electric vehicle, but with a small gasoline engine added as a generator. When you're driving, if the battery level is high, it runs purely on electric power, offering ultra-quiet operation and fuel efficiency; when the battery level drops, the engine automatically starts to generate electricity, charging the battery, and then the electric motor continues to turn the wheels. The engine isn't directly connected to the wheels, so the power delivery is always smooth. This design avoids the risk of a pure electric vehicle breaking down midway, such as during long-distance trips—you can refuel for unlimited range, unlike pure electric vehicles that need to find charging stations. My actual tests showed extremely low fuel consumption, with the engine only working when generating electricity, improving efficiency by over 50%. People looking to save money and hassle will love this system, but don't forget to perform regular maintenance on the engine part.
