What does light hybrid mean for small cars?

Light hybrid for small cars refers to vehicles being light hybrid electric vehicles. Below is a related introduction to light hybrid: 1. Hybrid system: The 48V light hybrid system is not simply an upgrade from 12V to 48V voltage. It is an addition—retaining the original 12V system while adding a 48V light hybrid system as an auxiliary. 2. Benefits: The greatest advantage of the 48V light hybrid system lies in its optimization during engine start-stop, acceleration, braking, and other conditions, which can directly save a significant amount of fuel. The higher voltage drives a more powerful start-stop motor, making it easier to turn the engine crankshaft, resulting in shorter system delays and reduced jerkiness.
A mild hybrid system involves adding a small electric motor and a compact battery to a conventional car, creating a mild hybrid setup. Unlike pure electric or plug-in hybrids that can drive solely on electricity, it primarily assists the engine during operation. For example, when stopped at a red light, the engine shuts off automatically to save fuel, as the small motor takes over some power supply; during acceleration, the motor provides a bit of extra thrust to ease the engine's workload. This setup can reduce overall fuel consumption by 5-10% and cut emissions slightly. Having driven many cars, I find this design clever—it doesn’t alter driving habits, keeps costs low, and suits compact cars well, serving as a transitional solution for small SUVs or urban vehicles moving toward new energy. In congested city driving, mild hybrids excel by saving money, being eco-friendly, and recycling braking energy—a practical compromise. However, it can’t run long distances on pure electric power, only offering minor assistance to the engine.
