What does Chevrolet mild hybrid mean?
1 Answers
It refers to adding a 48V mild hybrid system to the existing fuel-powered vehicle models. This system assists the vehicle during startup, thereby reducing fuel consumption. The greatest advantage of the 48V mild hybrid is that it can maintain the air conditioning cooling for a period of time even when the engine is turned off. Additionally, it provides a stronger sense of power during mid-to-low speed acceleration, and sufficient low-end torque at low speeds. Pros and cons of mild hybrid vehicles: 1. Advantages: The application of the 48V mild hybrid system enables the vehicle to support higher-power onboard systems, drive more powerful start-stop motors, and more easily rotate the engine crankshaft to wake up the engine, reducing system operation delays and jerky sensations. It also allows for more functionalities. Moreover, the 48V mild hybrid system can reduce energy consumption and emissions by approximately 15-20%. 2. Disadvantages: If the voltage is too high, issues such as high-voltage circuit protection, electromagnetic compatibility, and the stability of the onboard electrical system need to be considered, which can rapidly increase development costs. Fortunately, the 48V voltage is not excessively high, so system design under this framework is not overly complex. Most fuel-powered vehicles can retain their original powertrain architecture and overall layout. The 48V voltage is a good choice that balances cost, safety, and performance.
