The architecture of the power plant and the principle of operation of EREV
Heart. Li Auto L9 It is a 1.5-liter turbocharged internal combustion engine that performs the role of an electric power generator. It does not transfer torque to the wheels, but only charges the traction battery or directly feeds the electric motors at high speeds. This approach allows the engine to operate in the narrowest, most efficient range of revolutions, which significantly reduces fuel consumption and noise levels.
Two electric motors are responsible for the movement, located on the front and rear axles, providing the system with all-wheel drive. The total power of the power plant reaches impressive indicators, allowing the massive crossover to accelerate to 100 km / h in just 5.3 seconds. It does. Li L9 It is one of the most dynamic cars in its class, despite its weight.
The key feature is the ability to select different modes of operation of the power plant through a multimedia system. The driver can force the battery to be charged, maintain the current charge level, or allow the system to optimize its power consumption. This flexibility is especially valuable when planning long-distance travel, where it is important to allocate resources correctly.
β οΈ Warning: When operating in the "Mountain Pass" mode or when the car is fully loaded, the system can automatically start the engine to maintain battery power, even if the electric mode is selected. This is the normal operation of deep discharge protection algorithms.
Why did you choose a 1.5-liter engine?
The choice of a small engine volume is due to the fact that it does not need to directly rotate the wheels. Its task is to generate electricity with maximum efficiency (efficiency), working at constant speeds. This allows you to reduce the weight of the power plant and make room for an increased battery.
