Fast charging refers to a charging method that can bring the battery to or near full charge within 1 to 5 hours. Commonly used for traction batteries that require charging in a fully charged state in a short period of time. Fast charging is detrimental to the performance and longevity of the battery. The normal charging of the battery takes about 10 to 20 hours.
It is understood that the AC220V mains is stepped down by the transformer T1 and supplied to the charging circuit after full-wave rectification by D1-D4. After the output terminal is connected to the set bottle by the correct polarity, if the peak value of each half of the rectified output ripple voltage exceeds the output voltage of the battery, the thyristor SCR is triggered to conduct by the collector current of Q. The battery is charged via a thyristor. When the pulsation voltage is close to the battery voltage, the thyristor is turned off and charging stops. Adjusting R4 can adjust the turn-on voltage of transistor Q. Generally, R4 can be adjusted from large to small to enable Q-switching to trigger thyristor (conduction). In the figure, the luminous tube D5 is used as a power source indication, and D6 is used as a charging indication.
An electric car dealer said that he often received problems from the owner of the car after the roadside fast charging station was charged. "The normal battery life is about 2 years. It can be used for a long time, but the battery that is often charged at the fast charging station is absolutely miraculous if it can be used for more than two years." The electric car dealer said, " Fast charging will cause the battery plate to warp and increase the acid concentration, which will accelerate the aging of the battery and shorten the life. Because of the short circuit or other problems caused by rapid charging, even within the warranty period, it will not be Give the warranty. â€
Therefore, in order to make the battery life longer, it is best to use the matching charger that comes with the car when purchasing the electric car. Do not charge the electric car quickly when it is absolutely necessary.
