What Is an AC Charger?

A charging method that enables the battery to reach or approach a fully charged state within 1 to 5 hours. It is often used for charging when a traction battery needs to be restored to a fully charged state in a short time. The normal charging of a battery takes about 10-20 hours. How to quickly charge the battery without damaging the performance and life of the battery is a hot research topic that people pay close attention to.

1. After the output voltage is set (such as 36V), if the battery bottle plate is disconnected and disconnected, causing a certain group of batteries to fail or short circuit occurs, then

The AC220V city power is stepped down by the transformer T1, and after D1-D4 full-wave rectification, it is supplied to the charging circuit to work. When the output terminal is connected to the set charged battery with the correct polarity, if each half-wave peak value of the rectified output pulsating voltage exceeds the output voltage of the battery, the thyristor SCR is turned on by the collector current of Q, The battery is charged via a thyristor. When the pulsating voltage is close to the battery voltage, the thyristor turns off and stops charging. Adjust R4 to adjust the transistor Q

It was reported in November 2014 that an innovative battery technology in the United States will allow people to fully charge their mobile phones in just 12 minutes, which will mean that the history of mobile phone charging for several hours will no longer appear!

More importantly, researchers from the University of Maryland said that this latest invention will bring the miniaturized energy storage elements that people have long sought, and electric vehicles may benefit from this innovative technology.

Batteries called "nanopores" can carry electrolytes that hold charges between the ends of the nanotube electrodes, and millions of nanopore units can fit on a stamp-sized battery. ^[3]
