Many people think that the battery does not require maintenance, especially when using the UPS power supply, this idea is more obvious. However, in fact, problems caused by the lack of maintenance of the battery are quite high in all faults in UPS. Therefore, routine is maintained for the battery's battery, which will greatly extend the battery life of the UPS and reduce the fault rate. This article will introduce you to the maintenance method of the UPS battery.Be
Maintain a suitable ambient temperature
Be
Generally, factors affecting battery life is ambient temperature. The best ambient temperature required by the general battery manufacturer is between 20-25 ¡ã C. Although the temperature increases to increase the battery discharge capacity, the cost of pay is greatly shortened by the battery life. According to test assay, once the ambient temperature exceeds 25 ¡ã C, each liter 10 ¡ã C, the battery life will be shortened. At present, the battery used by the UPS is generally maintenance-free sealing lead-acid battery, and the design life is generally 5 years, which can be achieved in the environment required by the battery manufacturer. Without the prescribed environmental requirements, the length of its life is very different. In addition, the ambient temperature increases, causing chemical activity in the battery, thereby producing a large amount of thermal energy, which will increase the surrounding ambient temperature, which speeds up the life of the battery.
Be
Regular charging discharge
Be
The floating voltage and discharge voltage in the UPS power supply have been debugged to the rated value during the factory, while the size of the discharge current increases as the load increases, and the load should be reasonably adjusted, such as controlling the electronic device such as microcomputer. The number of users is used. Under normal circumstances, the load should not exceed 60% of the UPS rated load. In this range, the discharge current of the battery does not excessive discharge.
Be
UPS is connected to the market due to long-term power supply, and the battery will have a long-term power supply in a long time, and the battery will result in a long time to reduce the activity of battery chemistry and electrical energy to reduce the activity, accelerated aging. Shorten the service life. Therefore, it is generally discharged once every 2-3 months, and the discharge time can be determined according to the capacity of the battery and the load size. After the full load is complete, it is charged more than 8 hours according to the regulations.
Be
Use communication function
Be
Currently, there are most large, medium-sized UPSs have operational performance such as microcomputer communication and program control. Install the appropriate software on the microcomputer, connect the UPS through the string / parallel port, run the program, you can communicate with the UPS. Generally have functions such as information query, parameter setting, timing setting, automatic shutdown, and alarm. Through the information query, you can get information on the mains input voltage, UPS output voltage, load utilization, battery capacity utilization, temperature and market frequency; through parameter setting, the basic characteristics of UPS can be set, the battery can last time and The battery is used for agency. Through these intelligent operations, it greatly facilitates the management of UPS power supplies and its battery.
Be
Replace waste / bad battery in time
Be
At present, the number of batteries equipped with large and medium-sized UPS power supplies, from 3 to 80, or even more. These single batteries constitute a battery pack through a circuit connection to meet the needs of UPS DC power. In the continuous operation of UPS continuous operation, due to performance and quality, individual battery performance drops, and the storage capacity is not required to be damaged. When a certain / some batteries in the battery pack are damaged, the maintenance personnel should check each battery to exclude damaged batteries. When replacing new batteries, you should strive to purchase a battery with a model of the same model, prohibiting an anti-acid battery and a sealing battery, a battery of different specifications.
Be
This article gives four ways to extend the working life of the UPS battery. In general, it can be summarized as four sentences: suitable temperature, regular charging and discharging, good use of communication functions, and replace damaged batteries in time. There is no university or primary school in the learning of the power supply. As long as you pay attention to observation, you can summarize all kinds of features and methods for your desi Recommend: LiFePO4 Battery Manufacturer Energy storage battery Manufacturer Integrated machine energy storage battery series Manufacturer Lead lithium battery Manufacturer Outdoor Backup Battery Manufacturer Portable outdoor power supply Manufacturer Power battery Manufacturer Powerwall LiFePO4 Battery Manufacturer Battery rack Manufacturers Telecom LiFePO4 Battery Manufacturer Wall mounted battery storage Manufacturer China Lifepo4 Battery
