What does AMS mean in a car?

[LilahRose]

AMS in a car stands for the power management system. Its function is to enable the generator to determine the battery status through a current sensor, adjust the generator's load based on vehicle driving conditions, control battery charging and discharging, improve fuel consumption, and extend the battery's service life. Components of AMS: battery, generator, regulator, charging status indicator, switches, and the electrical system connected by wires. Working principle of AMS: during normal engine operation, the generator supplies power to electrical devices and charges the battery. During startup, the battery supplies power to the starter. The engine drives the generator to rotate via a belt, and as the engine speed changes, the generator's output voltage also changes.
