Can I charge the car at idle speed?

In the process of car charging, the essence is that the engine drives the magneto (generator) to generate electricity, and after rectification and voltage stabilization, it gives the battery a certain voltage, which is generally slightly higher than the battery voltage (for example, 14V, normal battery is 12V), thus realizing constant voltage charging.

When idling, although the rotation speed is low, it still drives the magneto to work, so it can output a stable DC voltage. Because the battery power is relatively not so large, it can be charged at idle speed, but the charging speed will be smaller.
