What does the Hongqi H5 48V mild hybrid system mean?

[OAvery]

Hongqi H5 48V mild hybrid system refers to the hybrid power of the car. More introductions about the mild hybrid system are as follows: 1. Introduction: Automobile mild hybrid power refers to the light hybrid vehicle. The automobile mild hybrid power changes the original power output mode of the car. The mild hybrid car generally adopts pure electric power to start, so there is no big vibration and noise when starting the car. The mild hybrid car has a power recovery system. When stepping on the brake, this system will recover the wasted energy and charge its own battery to achieve the effect of energy saving and emission reduction. 2. Classification of hybrid vehicles: Series hybrid electric vehicle (SHEV) is mainly composed of three major power assemblies, including engine, generator and drive motor, which are connected in series to form the power system of HEV. The engine and drive motor of parallel hybrid electric vehicle (PHEV) are both power assemblies. The power of the two major power assemblies can be superimposed and output, or output separately. Hybrid hybrid electric vehicle (PSHEV) is an electric vehicle composed of series and parallel structures, mainly composed of three major power assemblies, including engine, electric generator and drive motor.

The Hongqi H548V mild hybrid system actually refers to the 48-volt mild hybrid system equipped in Hongqi models. This is a design that combines a traditional fuel engine with a small electric motor, making driving more fuel-efficient and smoother. Simply put, it uses a 48-volt battery to assist the engine—such as enabling quiet starts during stop-and-go situations, providing extra power during acceleration, and recovering energy during braking to store it for later use. Unlike plug-in hybrids, it can't run purely on electricity for long distances, but it's much more cost-effective. Hongqi employs this technology primarily to reduce fuel consumption by about 10%, lower emissions, and improve responsiveness. In daily driving, the power delivery feels seamless, especially in urban stop-and-go traffic, making it more efficient. Installation isn't complicated, but battery lifespan requires attention to maintenance. Overall, it's an energy-saving and practical transitional choice.

I think the 48V mild hybrid system in the Hongqi H5 is quite common nowadays, as many cars are promoting this technology. It essentially integrates a small battery and electric motor into the powertrain to assist the engine. The benefits are particularly noticeable during driving - vibration-free starts, responsive acceleration, and significant fuel savings during stop-and-go traffic. The 48V system offers low costs and simple maintenance, unlike expensive pure electric systems. A friend who drives a Hongqi SUV mentioned that fuel consumption dropped from 10L to just over 8L after adopting mild hybrid, making it both eco-friendly and economical. However, don't expect pure electric range for long trips - it's mainly for short-distance assistance. Just be aware that battery replacement after aging might be somewhat troublesome, but overall it serves as a good transitional solution.

The Hongqi 48V mild hybrid system is a type of mild hybrid technology that uses a 48-volt battery and a small electric motor to assist the engine. Its core purpose is to enhance efficiency: enabling silent start-stop, energy recovery for acceleration and fuel savings, and smoother driving. Technically, it integrates a BSG (Belt-Driven Starter Generator) motor to replace the traditional alternator, with a lightweight design that doesn’t occupy extra space. Its advantages include easy installation, low cost, improved fuel economy, quick response, and reduced noise. The downside is that it cannot drive the vehicle purely on electric power, and the battery may require maintenance over time. Hongqi's adoption of this system makes its vehicles more eco-friendly and modern.
