Battery-overdischarge directly affects the DC screen battery voltage

　　 When the temperature of the battery changes by 10°C, the current will double. When the temperature is greater than 25°C, the battery will be overcharged and the switching power supply has not been turned off. At this time, the battery acts as a water electrolyzer. When the generated Joule heat is severe, the battery will run out of thermal control, which will cause the battery to lose water quickly, and the electrolyte in the diaphragm will quickly dry up. When the battery temperature is greater than 50°C, more than ten overcharges will cause permanent battery failure. The charge acceptance current of a battery is proportional to the square root of the discharge capacity. Every time the battery temperature rises by 10°C, the acceptance of the charge current under constant voltage will double. For any depth of discharge, the charge acceptance ratio of a battery versus the discharge current The number is proportional.

　　 The capacity of the battery changes with the change of temperature. The maintenance personnel must carefully adjust the discharge current of the battery according to the actual temperature change. A battery has several discharge rates. For discharge, the receiving current is the sum of the receiving current of each discharge rate. In other words, the acceptable current for charging the battery can be increased by discharging. Over-discharge indicates that the battery has been abused. Since batteries are always used for over-discharge, it is very necessary to improve and improve the over-discharge performance of such batteries. The occurrence of battery over-discharge is closely related to the user's method of use. Contact: 18038389279
