12V Stationary Battery Protector System

This device of 12V Stationary Battery Protector System is the Smart Stationary Battery Pulse Maintainer for 48V battery pack in series by 4PCS 12V cells. It is working as a new generation of high-tech products for daily battery maintenance and battery equalization in sites or other stationary power system. 12V Telecom Base Site Battery Protect System, it is designed for the charging maintenance and life extension of new batteries in Telecommunication base sites, or used after our Off line Battery Smart  Pulse Repair System restored  as 12V Battery Restore System. We also call it as well as on line Battery Smart Pulse Maintainer for its long-term work in parallel at the battery, the sulfated crystals can be effectively removed, and prevent the new sulphation re-buildup. The battery capacity is significantly maintained as new one for long time.

It is well known that Telecom service providers have designed the traditional wire-line telecom and wireless network systems for high service availability, its reliability depends on the availability of power from the stationary battery bank in base sites and UPS system standby in operation office. But there must be individual differences in state-of-capacity (SOC) and internal resistance(IR) Value of batteries after used for a certain number of years even if common Battery Care Program is carried out. It is called the battery un-equalization. Due to the total floating charge voltage of the rectifier remains unchanged and keeps constant, when the battery pack is always in floating charging status, the floating voltage of the cells with larger IR will be higher than that of the normal battery, resulting in the normal battery's floating voltage is lower. 

Batteries floating charged in this unbalancing way for a long time without Base Site Battery Protector System or Stationary Battery Pulse Equalizer, that will cause the higher voltage cells seriously dehydrated, and the lower voltage cell is in a state of under-charged. This way of vicious spiral formed will accelerate the base site batteries premature sulfation and early failure.

This 12V telecom base site Battery Smart Pulse Protector set a equalized charging function. If the terminal floating voltage of the battery system is higher than the standard value of protector system designed, the system automatically and smartly switches to the over-voltage balanced working state. When the voltage drops lower than standard value, it automatically changes to Stationary Battery Pulse Maintainer state. The decrease of battery IR and the improvement of the battery equalization lead to the battery life extension doubled or more.

TECHNICAL FEATURES:

• The long-term work in parallel at the battery, the sulfated crystals can be effectively removed, and prevent the new sulphation buildup. The battery capacity is significantly maintained as new one for long time.
• MCU ( Micro-controller Unit) design, Constantly scanning the battery terminal voltage and reasonable output digital intelligent resonance pulse. 
• Built-in 8 bit precise A/D converting circuit to real-time monitor battery voltage, according to the change of cells terminal voltage value, smartly and automatically switch in 3 working states of under-voltage shutdown protection, cells equalized and optimized charging maintenance and pulse maintenance work
• The decrease of cells internal resistance, improve the cells capacity consistency of the series battery bank
• Without any damage on charging equipment and battery plates
• Has the function of over-current protection, even inadvertently reverse polarity will not damage their own instruments
• Also has voltage detection and equalization circuit, can significantly improve the equalization of cell voltage and capacity
