What is the relationship between the life of Panasonic batteries and the environment?
Matsushita battery life and the use of environmental issues also have a certain relationship, so today let Xiaobian detailed for you to introduce it!
Generally speaking, the life of maintenance-free lead-acid Panasonic batteries will be halved if the working environment temperature rises by 10 degrees on the basis of 25 degrees Celsius. When the power supply is in the floating charge state, it needs to be compensated by reducing the floating charge voltage. The compensation coefficient is that the floating charge voltage of each cell (2V cell) decreases by 3 to 5mV for each rise of the ambient temperature by 1C. The reason why periodic discharge is dangerous is that if there is a malfunction in the power supply or AC power supply just before the battery is finished, the battery will become virtual.
For the case of deep discharge, it is better to charge Panasonic batteries by "constant voltage and current limiting" method. The charging mode and parameters are mainly determined by the characteristics of the battery. After power failure, the battery pack supplies power to the load and monitoring module. The monitoring module monitors and calculates the parameters of the battery pack. After power recovery, in the soft start process of the rectifier, the monitoring module transfers the calculated parameters of the output voltage and current (current limiting point) of the rectifier to the rectifier, and the rectifier is executed according to these parameters. At this time, the rectifier is required to have the function of stepless current limiting, so that the battery can get the best charging current. For the case of shallow discharge, it should be charged equally or floated directly according to the actual situation. Above all, the daily management of Panasonic batteries is discussed. Next, I want to talk about a statement that in order to protect the batteries, they must be discharged regularly. Regular discharge of batteries is not only unnecessary, but also dangerous.
It should be noted that temperature compensation function can only play a role in a certain range. The best operating temperature of Panasonic battery is in the environment of 20-25 degrees Celsius. Therefore, it is important to control the ambient temperature of the battery for its service life.
