Many people think that the lifePo4 batteries is maintenance-free, especially when using a UPS power supply, this idea is even more apparent. But in fact, the problem is due to the lack of maintenance caused by battery failure in all UPS's share is quite high. Therefore, routine maintenance of UPS lifePo4 batteries, UPS will largely extend the battery life and reduce the failure rate. This article will introduce you to UPS lifePo4 batteries maintenance methods.
Maintaining Proper Temperature
Generally, factors affecting lifePo4 batteries life is greater ambient temperature. The optimal ambient temperature is generally required for battery manufacturers is between 20-25 ℃. Although the temperature rise of the battery discharge capacity has increased, but at the expense of lifePo4 batteries life is shortened. According to tests measuring the ambient temperature once more than 25 ℃, every increase of 10 ℃, the battery life will be shortened by half. UPS lifePo4 batteries currently used are generally maintenance-free sealed lead-acid battery design life expectancy is five years, which can be achieved at battery manufacturer demanding environments. The lifepo4 battery also can be used in solar power portable generator. Not reach the environmental requirements, there is a great difference in the length of its life. In addition, to improve the ambient temperature, it will cause the battery internal chemical activity increased, resulting in a lot of heat, in turn prompting the ambient temperature rises, this vicious cycle will accelerate shorten lifePo4 batteries life.
Regularly Charge and Discharge
UPS power supply in the float voltage and discharge voltage at the factory have been commissioning rating, while the discharge current size increases as the load increases, the use should be reasonable to adjust the load, such as the control computer and other electronic equipment It uses several. Under normal circumstances, the load should not exceed 60% UPS rated load. In this range, the lifePo4 batteries discharge current will not over-discharge.
UPS due to the long connected to the mains, the supply of high quality, rare power cut use of the environment, the battery will be a long period of float charge state, the course of time will lead to battery chemical energy and electrical energy into each activity decreased, accelerated aging and shorten life. Thus, generally every 2-3 months should be fully discharged once the discharge time can be determined based on the lifepo4 battery pack capacity and load size. After a full load discharge is complete, the required recharge more than 8 hours.
Use of Communications Capabilities
Currently, the vast majority of large and medium-sized UPS are equipped with computer communication and control procedures operability. Install the appropriate software on the PC connected to UPS through the serial / parallel port, run the program, you can use the computer to communicate with the UPS. Generally have information query, parameter settings, set the timer, automatic shutdown and alarm functions. Through information query, you can get the mains input voltage, UPS output voltage, load utilization,lifePo4 batteries capacity utilization, internal temperature and mains frequency information; through parameter settings, you can set the basic characteristics of UPS, battery time and can be maintained battery runs out alarms. Through these intelligence operations, which greatly facilitates the use of lifePo4 batteries and UPS power management.
The Timely Replacement of the Waste or Bad Battery
Currently the number of medium and large UPS lifePo4 batteries power supply is equipped from 3-80 dollars, or even more. These individual cells through a circuit connected to form a battery pack to meet the needs UPS DC power supply. UPS running in continuous use, due to the difference in performance and quality on individual lifePo4 batteries performance, storage capacity is mainly the damage is inevitable. When the battery pack in a / some cells are damaged, the maintenance personnel should be checked for each battery test, to exclude damage to the battery. When replacing a new battery, it should seek to buy with the same type of battery manufacturers prohibit anti-acid batteries and sealed batteries, mix batteries of different specifications.
