What does a 12V mild hybrid system mean?
1 Answers
Audi's 12V mild hybrid system operates on the following principles: 1. It essentially simplifies the 48V mild hybrid system: Instead of adding a separate 48V battery to the traditional 12V electrical system, it replaces the standard 12V lead-acid battery with a 12V11Ah lithium-ion battery. 2. The electric motor is significantly smaller than in 48V systems: However, it can still provide the engine with 1kW of power, reducing fuel consumption by 0.4L/100km. 3. The 12V mild hybrid system refers to a vehicle's powertrain configuration: Vehicles equipped with this system typically feature a starter-generator that can deliver kinetic energy via a belt (the essence of "mild hybrid"), along with an additional 12V lithium-ion battery to power this starter-generator and store generated electricity. 4. The mild hybrid system improves engine efficiency: It recovers and stores vehicle energy in the battery, which can then work in conjunction with the engine to enhance operational efficiency when needed. While the system recovers some energy for battery storage, the vehicle cannot run solely on electric power. The electric motor can assist the engine to boost power output when required.
