• Generates three-phase AC through electromagnetic induction, converted to 12V DC via a rectifier bridge.
• Built-in electronic regulator stabilizes output voltage at 13.5–14.5V, preventing overvoltage/undervoltage.
• Coordinates with BMW DME to adjust power generation based on engine speed and load, balancing power and supply.
