Whether the car battery will freeze or not is related to its battery type, for example, when the temperature is very low, lead-acid batteries will freeze, lithium iron phosphate and ternary lithium-ion batteries generally do not appear icing phenomenon.
1. Automotive batteries in the maintenance and installation, due to the replacement of unqualified batteries, adding too much distilled water leading to a decrease in the density of the battery liquid, when the water accounted for the percentage of the battery liquid rises leading to the freezing point of the battery liquid rises.
2. In our daily use of the process of battery power is too low, resulting in a decline in the density of electrolyte, the proportion of sulfuric acid and water imbalance makes the battery liquid freezing point rise, if not timely charging, coupled with the cold weather outside, will lead to automotive battery icing.
3. The electrolyte density of the automobile storage battery from the factory is low, and the electrolyte reaches the freezing point and freezes when it is used in cold areas.
1. The electrolyte of lithium iron phosphate battery contains less organic matter and is not easy to freeze in low temperature environment.
2. Ternary lithium-ion batteries are better at resisting freezing in low temperatures, although they can be affected. The reason is that the electrolyte of the ternary lithium-ion battery is an organic electrolyte, and the electrolyte contains substances with a low melting point, which have a certain degree of frost resistance.
Automotive batteries are mainly composed of positive and negative plates, separators, electrolyte, tank shells, connecting strips and stakes. The main effect of cold weather on the car battery is the electrolyte, which is mainly composed of about 25% sulfuric acid and 75% distilled water. Automotive batteries utilize a chemical reaction to convert energy stored in the form of lead and sulfuric acid into electrical energy. This chemical reaction is very sensitive to temperature, and low temperatures can slow down or even prevent the reaction from occurring altogether. The main effects are as follows:
1. Cold weather slows down the changes in the chemical reactions of the battery, so lower temperatures reduce kinetic energy.
2. It may cause the water in the electrolyte to freeze, and the battery may bulge, and in severe cases, it may cause the shell to rupture and the electrolyte to leak out, which may cause damage to the battery, resulting in the automotive battery not being able to be used normally.
3. Automotive battery capacity reduction. With the advent of cold weather, the capacity of the battery will also decrease.
4. Battery fluid will thicken. Cold weather can cause the battery fluid in automotive batteries to thicken, similar to the thickening of winter fluids. The increased density of the electrolyte will impede the flow of the liquid and reduce the efficiency of the battery. As a result, the output will be reduced, leading to difficulties in starting the car or running the electrical system.
5. Charging slows down due to colder batteries in cold weather.
1. Maintain a clean and dry battery, cold weather can lead to the formation of condensation on the battery, which can lead to corrosion on the surface of the battery. It will also lead to dilute the electrolyte, which can lead to battery short circuit.
2. In daily life to maintain sufficient power, sufficient power in cold weather is not easy to lead to ice, the battery will be used for a longer time.
3. Vehicles parked in a suitable place, it is best to be able to Park in a warm garage or install a battery blanket.
4. Do not often use rapid charging and excessive use of the vehicle to the state of loss of power, low temperature environment will lead to the chemical reaction of the battery slows down, often rapid charging and discharging will affect the battery.
5. You can use the maintenance battery charger, which can keep the voltage in a stable state, play the role of maintenance battery.
The battery in cold weather are different effects, but whether it will freeze need to consider the specific circumstances, battery type and so on. In the battery problems, if you do not know, please turn to maintenance personnel to ensure personal life safety.
