Does the outside temperature affect the service life of the battery? ? How much do you know about this problem? ? Today, the editor of Zhengzhou Kanglida Electronic Power Supply Co., Ltd. will give you some information on this issue. I hope it will be helpful to you. In the future, you can avoid detours when using and purchasing.
The rated capacity of the battery refers to the value of the battery at 25℃. It is generally considered that the working temperature of the valve-regulated sealed lead-acid battery is ideal to work in the range of 20~30℃.
When the battery temperature is too low, the battery capacity is reduced, because the electrolyte cannot fully react with the active material of the electrode plate under low temperature conditions. The capacity reduction will not be able to meet the expected backup use time and remain within the specified depth of discharge, which will easily cause over-discharge of the battery.
From the perspective of the external parameters of the battery, the voltage has a great relationship with the temperature. When the temperature increases by 1℃, the voltage drop of the single cell decreases by 3mV. In other words, the voltage of a lead-acid battery has a negative temperature coefficient, and its value is -3mV/°C.
Similarly, an increase in ambient temperature is likely to cause over-discharge of the battery. High temperature will also bring about the phenomenon of battery loss of water and thermal runaway. Temperature is a major factor affecting the normal operation of the battery. In solar photovoltaic systems, the controller is generally required to have a temperature compensation function.
