Why is the battery connected to a rectifier
Charging current limiting function Currently access network site is almost all use of VRLA batteries, due to the tight assembly of the battery structure, in the high current charging, will cause the battery drums even heat out of control phenomenon, it must have a battery charge current limit Stream function. Battery over discharge protection function of the battery over discharge will have a great impact on the battery life, a depth of over-discharge may reduce the battery life of 1 to 2 years, and even cause the battery scrapped. Therefore, the rectifier over-discharge protection function is also an important indicator.
The purpose is to filter and reduce the impact on the battery, filter, reduce electrical equipment interference, so that sound more pure sound, power cleaner, reduce the impact of many devices are large power users on the battery instantaneous demand will make the battery Aging, early retirement, if there is a rectifier will have some power, electricity will not directly use the battery power, which play a protective battery, these rectifiers are basically large capacity inside the capacitor, the Internet has its own DIY.
The rectifier should have an automatic float management program. When the AC power is restored and the power supply is resumed or the continuous float is running for about 3 months, the battery pack is automatically charged to reduce the charging time, eliminate the battery behind the battery and prevent the passivation of the battery active material.
Access network site is rarely equipped with air conditioning, so the ambient temperature changes, the internal chemical reaction speed of the battery has a great impact. Rectifier temperature compensation function is to minimize the impact of temperature on the battery. The general requirements of the ambient temperature for each rise once, each section 2V battery float voltage to reduce 3 ~ 5mv, and vice versa. As a result of a variety of batteries using different materials and materials, the actual application of the battery manufacturers to give the data to adjust.
