What are the precautions for Panasonic battery maintenance?
Panasonic battery maintenance mode will also affect the service life of the battery, so do you know what needs to be paid attention to when Panasonic battery maintenance? Here is a detailed introduction:
1. Maintain proper ambient temperature
According to the test, once the ambient temperature exceeds 25 ℃, the life of Panasonic battery will be shortened by half every 10 ℃. At present, the batteries used in UPS power supply are generally maintenance free sealed lead-acid batteries, and the design life is generally 5-10 years, which can be achieved in the environment required by Panasonic battery manufacturers. If they fail to meet the specified environmental requirements, their life span will vary greatly. In addition, the increase of ambient temperature will lead to the increase of chemical activity inside the battery, resulting in a large amount of heat energy, which in turn will promote the increase of ambient temperature. This vicious cycle will accelerate the shortening of battery life.
2. Generally speaking, the environmental temperature is the major factor that affects the battery life. Generally, the best environment temperature required by battery manufacturers is between 20-25 ℃. Although the discharge capacity of the battery increases with the increase of temperature, the cost is that the battery life is greatly shortened.
The battery used in UPS power supply equipment is in the state of floating charge for a long time, which will lead to the reduction of the activity of mutual conversion of chemical energy and electrical energy of the battery and the shortening of the aging service life of the product. Therefore, the battery should be fully discharged every 2-3 months, and the discharge time can be determined according to the capacity and load of the battery. After a full load discharge, recharge for more than 8 hours as required. The floating charge voltage and discharge voltage in the UPS power supply have been adjusted to the rated value at the time of delivery, while the discharge current increases with the increase of load, so the load should be calculated in use, such as the number of electronic equipment such as control microcomputer. Generally, the load shall not exceed 80% of the rated load of UPS unit. In this range, the discharge current of battery will not be over discharged.
3. Using the communication function
At present, the vast majority of large and medium-sized ups have the operability of computer communication and program control. Install the corresponding software on the computer, connect UPS through serial / parallel port, run the program, you can use the computer to communicate with ups. Generally, it has the functions of information inquiry, parameter setting, timing setting, automatic shutdown and alarm. Through information query, information such as mains input voltage, UPS output voltage, load utilization rate, battery capacity utilization rate, internal temperature and mains frequency can be obtained; through technical parameter setting, basic characteristics of UPS power supply, battery maintenance time and battery depletion alarm can be set. Through these intelligent operations, it is convenient to manage the use of UPS power supply and its battery.
4. Replace the defective battery in time
When one or more batteries in the battery pack are damaged, the maintenance personnel shall check and test each battery to eliminate the damaged batteries. At present, the number of batteries for large and medium UPS power supply varies from 3 to 80, or even more. These individual batteries are connected to form a battery pack through a circuit to meet the needs of UPS DC power supply. When replacing a new battery, try to buy the same type of battery from the same manufacturer. It is forbidden to mix acid proof battery, sealed battery and battery of different specifications. In the continuous operation and use of UPS power supply, due to the difference in performance and quality, it is inevitable that some batteries will be damaged due to performance degradation and storage capacity failure to meet the requirements.
