All good. Ha ha
1, the circuit characteristics are different: fast charge, if the two output short circuit, because the thyristor SCR trigger circuit in the charger can not work, so the thyristor is not on, the output current is zero; When the battery is slowly charged, the positive and negative electrodes are mistakenly reversed, then the thyristor trigger circuit is reversed off, there is no trigger signal, the thyristor is not switched on, and the output current is zero.
2, the main body is different: fast charge in 1 ~ 5h to make the battery reach or close to the state of full charge; Slow charge refers to the process of replenishing a device, such as a battery.
3, the principle is different: when fast charging, the output end is connected to the charged bottle according to 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; 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.
The IPhone 14 promax mobile phone is generally better to fast charge than slow charge, although slow charge can save battery life, but the efficiency will be greatly reduced when using, the effect of this sacrifice is not good, so fast charge should be used when using
