The main body is different: fast charge: A charging method that can make the battery reach or approach the fully charged state within 1 to 5h.
Slow charge: refers to the process of replenishing the power of a device such as a battery. The principle is different: fast charge: when the output end is connected to the charged bottle set by the correct polarity, if each half peak of the rectified output pulsating voltage exceeds the output voltage of the battery, the SCR is triggered by the collector current of Q, and the electricity flows through the thyristor to charge the battery.
Slow charge: The principle is to let the direct current pass in the opposite direction of the discharge to restore the active substance in the battery.
The difference between slow charging and fast charging is the following:
The subject is different;
The circuit characteristics are different;
The principle is different;
Charging method is different;
Charging interface is different;
Charging pile size is different:
It is direct current, so whether you use fast charge or slow charge, you need to convert alternating current into direct current.
