What is the reason for the smaller if the electric vehicle battery is smaller?

In the process of electric vehicles, it will be found that the battery capacity is slowly reduced, and the distance is getting lower and lower. The following small series tells you that the electric car battery capacity is reduced. First, the battery is lost and the electrolytic chemical reaction cannot occur.

The severe downtime will make the electrolyte deterioration or become a hard block; The polar coating is gradually dropped, causing the battery capacity to cut, typically connect the final one-piece battery of the battery pack negative electrode, which is caused by over-discharge; three, battery short circuit, broken, etc. Fourth, the battery polar plate is vulcanized by crystallization, and the severe vulcanization will corrode the plate to complete necrosis; five, the battery polar plate is softened by overcharge or over-discharge, and some causing a platelet to fall, perforated, Shell deformation or electrolyte leakage, etc. When the electrolyte temperature is high, the speed of molecular motion increases, and the energy can be added, so the permeability is added, the electrolyte resistance is reduced, the degree of diffusion is increased, and the electrochemical reaction is enhanced, and the capacity of the lead-acid battery increases.

When the electrolyte temperature drops, the permeability is weakened, so the electrolyte resistance is increased, the degree of diffusion is lowered, and the electrochemical reaction is slow, so that the capacity of the battery is reduced. When the electrolytic temperature is at 30 ¡ã C, the capacity is approximately 100%. When the temperature is increased, the capacity of the battery is increased.

However, when a certain limit is exceeded, it is easy to reduce the capacity of the positive electrode plate bend and the negative board, and the local discharge of the battery is increased, so in daily maintenance, the general electrolyte temperature should be maintained between 20 and 30 ¡ã C, even During the charging process, the electrolyte temperature must not exceed 40 ¡ã C. Due to the temperature of the capacity of the lead-acid battery, the temperature is very affecte.
