How do car batteries and generators work together? -High Score

The car is a "dual power" compound circuit

When the engine is not started, the whole car is powered by the battery

When the engine is started, the whole car is powered by the battery and the generator **** together (when the engine rpm is lower than the rpm needed by the generator, the battery provides the power)

When the engine speed is higher than the required generator speed, the generator charges the battery, and the battery stores energy

When the battery voltage rises to 13.8-14.2V (the termination voltage of battery charging), the generator regulator cuts off (or reduces) the excitation, so that the voltage of the whole vehicle stabilizes at this voltage for battery charging

Answer added:

When the generator voltage is higher than the battery termination voltage, charging; when lower, discharging.
