Definition and Classification of Mild Hybrid Vehicles

A mild hybrid vehicle (MHEV) is a hybrid vehicle that uses a conventional internal combustion engine as the primary power source and integrates a 48V low-voltage motor system. Unlike full hybrid systems, the motor cannot independently drive the vehicle. Instead, it mainly provides functions such as start-stop assistance, launch assistance, regenerative braking energy recovery, and idle voltage stabilization.

MHEVs do not require large-capacity traction batteries or external charging systems. They feature limited structural modifications, lower manufacturing costs, and primarily aim to optimize engine operating conditions, reduce idle fuel consumption and emissions, and improve low-speed driving smoothness. They are not categorized as hybrid systems capable of pure electric driving.

Based on structural configuration, mild hybrid systems can be divided into four major types:

• BSG (Belt Starter Generator) Mild Hybrid System: The motor is installed on the engine belt drive system. It features the simplest structure and the widest adoption.
• ISG (Integrated Starter Generator) Mild Hybrid System: The motor is integrated coaxially with the crankshaft, providing faster response and stronger power assistance.
• P0 Mild Hybrid System: The most basic configuration, where the motor is externally mounted on the engine belt system.
• P1 Mild Hybrid System: The motor is integrated with the crankshaft, offering improved performance.

In terms of voltage architecture, the 48V system has become the mainstream standard, while older 12V mild hybrid systems have largely been phased out. Most passenger vehicles equipped with mild hybrid technology currently adopt the 48V configuration.

Application Analysis of Mild Hybrid Vehicles

Mild hybrid technology utilizes 48V motors to provide start-stop functions and auxiliary power assistance. Due to its relatively low modification cost and noticeable fuel-saving effects, it can be applied across various vehicle categories.

Passenger Vehicle Applications

Passenger vehicles represent the primary application area. Family sedans and urban SUVs are widely used for daily commuting and short-distance transportation. Mild hybrid systems significantly reduce idle fuel consumption during low-speed traffic congestion.

Luxury gasoline-powered vehicles and mid-size SUVs utilize mild hybrid technology to improve launch smoothness and driving comfort, making them suitable for short-distance urban and intercity travel.

Commercial Vehicle Applications

In commercial vehicles, major applications include light trucks, urban delivery mini-trucks, and short-distance passenger vans. These vehicles frequently operate under stop-and-go conditions in urban environments, where mild hybrid systems can effectively reduce fuel consumption and exhaust emissions.

The penetration rate of mild hybrid technology in heavy-duty commercial vehicles remains relatively limited.

Other Applications

Other application areas include lightweight engineering vehicles, airport shuttle vehicles, and small recreational vehicles. These applications are mainly used in enclosed industrial parks, short-distance transportation, and leisure scenarios characterized by low speeds, short travel distances, and frequent starts and stops.

Overall, mild hybrid technology demonstrates strong compatibility with low-speed and frequent stop-start operating conditions. Passenger vehicles currently represent the largest demand segment, while urban commercial delivery vehicles are expected to become an important growth market.
