How to do the battery icing

It is not unfamiliar to the battery. The battery is an important part of the UPS power supply. When the battery is used in winter, it may also suffer from freezing. What should I do if the battery is frozen? The following Xiao Bian will introduce specific solutions.

How to deal with battery icing?

Since the battery fluid in the battery is water and sulfuric acid, the battery is likely to freeze at low temperatures. What happens when the battery icing happens?

First of all, I will not study whether battery liquid will freeze. First, what should I do after the battery is frozen?

After the battery freezes, the vehicle will not start. The battery should be removed from the car and then moved to a heated indoor location where the battery fluid can be melted and then loaded into the car. Of course, the battery can be prevented from freezing when the battery is removed at night and stored in a warm place.

Will the battery freeze?

The battery will freeze in the following situations:

1 Adding too much distilled water leads to a decrease in the battery fluid density. At this time, the increase in the percentage of water in the battery fluid leads to an increase in the freezing point of the battery fluid.

2 Over-discharge leads to a decrease in the density of the electrolyte, and the imbalance between the ratio of sulfuric acid and water causes the freezing point of the battery liquid to rise.

What is the degree of freezing in the battery electrolyte?

The normal battery sulfuric acid concentration is 35% - 40% According to the "sulfuric acid - water mixture freezing point curve" can be found that the electrolyte's freezing point is about -60 degrees Celsius to -50 degrees Celsius. From the data point of view, as long as the battery fluid density is between 1.25-1.30, it is unlikely that there will be ice (unless you use a car in very northern China).

However, as the concentration of sulfuric acid decreases, the freezing point of the battery fluid rises with it, which makes it possible for the battery fluid to freeze. For example, the winter minimum temperature in Beijing is generally at minus ten degrees. When the battery fluid density is as low as 1.10, the battery may have the possibility of freezing. The most common cause of these changes is excessive battery discharge.
