What is the relationship between the working temperature of the small battery and charging and discharging
What is the relationship between the working temperature of the small battery and charging and discharging? ? How much do you know about this problem? ? Today, the editor of Zhengzhou Kanglida Electronic Power Co., Ltd. will give you some information on this issue. I hope it will be helpful to you. You can avoid detours when you use it in the future.
The ambient temperature of the small battery is maintained at 20℃-25℃, which is the ambient temperature required by the battery manufacturer. Although the increase in temperature improves the discharge capacity of the battery, the price paid will greatly shorten the life of the battery. According to the test, once the ambient temperature exceeds 25°C, the battery life will be shortened by half for every 10°C increase. At present, the batteries used by UPS are generally maintenance-free sealed lead-acid batteries, and their lifespan is generally 5 years, which can only be achieved in the environment required by the battery manufacturer.
If the small battery fails to meet the specified environmental requirements, the life span of the battery will vary greatly. The reason for the enhanced chemical activity inside the battery is the increase in the ambient temperature, which will also cause it to generate a lot of heat. The increase in the ambient temperature is also caused by this reason. This is a vicious cycle that will accelerate the shortening of the battery's life. The float voltage and discharge voltage in the UPS power supply have been adjusted to the rated value at the factory, and the discharge current increases with the increase of the load. The load should be adjusted reasonably during use, such as the control of electronic equipment such as microcomputers. Number of units used. Under normal circumstances, the load should not exceed 60% of the UPS rated load. Within this range, the discharge current of the battery will not be over-discharged.
Because the small battery is connected to the mains for a long time, the battery will be in a floating charge state for a long time in an environment where the power supply quality is high and the mains power failure is rare. The activity decreases, accelerating aging and shortening the service life. Therefore, in general, it should be completely discharged every 2-3 months, and the discharge time can be determined according to the capacity of the battery and the size of the load. After a full-load discharge is completed, charge it for more than 8 hours according to the rules.
