What does the Geely Jiaji Mild Hybrid mean?

Geely Jiaji Mild Hybrid refers to the addition of a BSG (Belt Starter Generator) mild hybrid system to the original vehicle, commonly known as MHEV (Mild Hybrid Electric Vehicle). The difference between it and PHEV (Plug-in Hybrid Electric Vehicle) is that it does not require charging. The 48V battery in the mild hybrid system is automatically charged by the vehicle's energy recovery system (braking/coasting recovery), eliminating the need for external charging. Below is an introduction to the Geely Jiaji: 1. The Jiaji new energy model will be equipped with a 1.5TD engine jointly developed by Geely and Volvo (1.5TD-BSG mild hybrid version and 1.5TD-PHEV plug-in hybrid version). The mild hybrid version is paired with a 7DCT high-efficiency transmission, featuring the industry's highest 97% transmission efficiency for wet 7DCT. 2. The Jiaji MHEV model is equipped with Geely's self-developed 48V-BSG mild hybrid system, delivering a maximum power of 140kW and a maximum torque of 300N.m, with a fuel consumption of only 5.9L per 100km, offering the strongest power and ultra-low fuel consumption in its class.
A mild hybrid means the vehicle is equipped with a 48V small motor to assist the engine. In my Jiaji, the most noticeable improvements are the quicker acceleration from a standstill, uninterrupted air conditioning cooling during auto start-stop at traffic lights, and the battery's ability to recover braking energy. In practice, it saves nearly 1 liter per 100 kilometers in city driving, and it's significantly smoother and quieter than the regular fuel-powered version. This system is cost-effective, simple to maintain, and represents a highly economical hybrid solution, especially suitable for family MPVs in daily commuting.
For those who've driven the Jiaji Mild Hybrid, here's the scoop: its engine bay hides a 48V motor + lithium battery pack. The motor assists the engine in two ways—giving it a boost during acceleration to save fuel, and generating electricity to store energy during deceleration. The best part is the start-stop function. Traditional cars shake noticeably during start-stop, but the mild hybrid starts as smoothly as an electric vehicle thanks to the motor. I've been using this car to pick up my kids for three years, saving nearly 6,000 yuan in fuel costs, and haven't had to replace the battery yet. The durability is truly reliable.
