The difference between slow charging and fast charging is that the main body is different, the circuit characteristics are different, and the principle is different.

Main body: Slow charge refers to the process of replenishing power to devices such as batteries. Fast charge is a charging method that can make the battery reach or close to the fully charged state within 1 ~ 5h.

Circuit characteristics: When the battery is mistakenly connected to the positive and negative electrodes in slow charge use, the thyristor trigger circuit is reversed off, no trigger signal, the thyristor is not switched on, and the output current is zero. If the fast charge is short circuited in the two output terminals, the thyristor SCR trigger circuit in the charger cannot work, so the thyristor does not conduct, and the output current is zero.

Principle. The principle of slow charge is to let the direct current pass in the opposite direction of the discharge to restore the active substance in the battery. 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.
Different from the charging time, the impact on the battery is different.
Charging time is different: 1, fast charge half an hour can charge 80%. 2, slow charge takes 6 to 8 hours to be full.
The impact on the battery is different: 1, fast charging will have certain damage to the battery. 2, slow charge on the battery life will be better.
The main difference between new energy fast charging and slow charging is that the charging speed is different and the charging pile interface is different. The difference between fast charging and slow charging is as follows: Charging time: Generally speaking, slow charging of new energy vehicles takes 8-10 hours to fully charge the battery, and fast charging only takes 1 hour to charge the battery to 80% of the electricity. When driving outside, you can use the fast charge, more convenient and fast. When shopping or eating, it only takes 1-2 hours to recharge the car battery. Advantages of fast charging and slow charging: The advantage of using fast charging is fast and time-saving. However, the fast charge is direct current, the requirements for the battery are not the same, the power of direct current is relatively large, and the life of the battery will be affected for a long time.
The advantage of using slow charge is that it will not cause any damage to the battery, and the charge is true, relatively easy to use, but the charging speed is relatively slow, sometimes causing unnecessary trouble.
