What does Cadillac's 48V mild hybrid system mean?
2 Answers
Cadillac's 48V mild hybrid system builds upon the traditional 12V electrical system by increasing the voltage to 48V and incorporating components such as electric motors and battery packs. This enables the system to assist in vehicle propulsion and store/recover electrical energy. Taking the 2021 Cadillac CT5 28T Technology model as an example: it is a mid-size 4-door 5-seater sedan equipped with a 10-speed automatic transmission and a 66-liter fuel tank. The dimensions of the 2021 Cadillac CT5 28T Technology model are 4924mm in length, 1883mm in width, and 1453mm in height, with a wheelbase of 2947mm. It has a top speed of 240 km/h and uses front-engine rear-wheel drive configuration.
The Cadillac 48V mild hybrid system is one of the most innovative features I've experienced in a car. It uses a 48-volt battery to assist the traditional gasoline engine, automatically shutting off the engine when idling to save fuel and providing a smooth, jerk-free start when moving. This system also recovers braking energy, converting it into electricity for later use, such as providing a boost during acceleration, which can reduce fuel consumption by about 10%. My XT6 is equipped with this system, and the fuel savings in city driving are noticeable, while the engine's lifespan is also extended. Cadillac uses this technology to enhance driving quality, making luxury cars more eco-friendly. Battery maintenance is straightforward, with replacements every five years being relatively affordable. Overall, it's reliable, which is why mild hybrids are becoming so popular.
