The internal temperature of the battery is very harmful to the performance of the lead-acid battery

The internal temperature of the battery is very harmful to the performance of the lead-acid battery. Due to the oxygen circulation system inside the battery during the charging and discharging process, the additional heat will increase the temperature of the battery, so the damage is more serious. As the temperature increases, the physical exercise rate of the lithium battery electrolyte increases, and the mechanical energy increases, which leads to an increase in the permeability of the electrolyte, a decrease in resistance, an increase in electrochemical corrosion, and an expansion of the battery. When the temperature decreases, the viscosity of the lithium battery electrolyte increases, resulting in ion movement.

The internal temperature of the battery has a great hazard to the performance of lead-acid batteries

For lead-acid batteries, The internal temperature is very harmful to its characteristics, because there is an oxygen circulation system during the entire process of battery charging, which causes extra heat to increase the temperature of the battery, so the harm is greater. Therefore, when solving the battery characteristics, the temperature should be considered. harm. As the temperature increases, the physical exercise rate of the lithium battery electrolyte increases, and the mechanical energy increases, which leads to an increase in the permeability of the electrolyte, a decrease in resistance, an increase in electrochemical corrosion, and an expansion of the battery. When the temperature decreases, the viscosity of the lithium battery electrolyte increases, causing the positive ion movement to receive great frictional resistance, the external diffusion ability is reduced, and it is difficult to enter the inside of the plate. The most active material cannot be used flexibly due to the lack of acid, resulting in volume Decrease. Second, the resistance of the lithium battery electrolyte increases with the decrease in temperature, which leads to an increase in battery resistance and current expansion, thereby reducing the volume. The change in battery volume is called the temperature coefficient of the battery volume. Under general conditions, the correlation between volume and temperature is expressed as the volume of ct1 at t1c (ah), the volume of ct2 at t2c (ah), the volume of cell electrolyte temperature (c) (k) t1 and t2 The temperature coefficient.

Battery charging mode

Nowadays, there are more and more electric motors in cars, so buyers do not have to overload the battery when using it. Overloading the battery will reduce battery life. It is very important to master the proper battery charging method.

First of all, there are two types of rechargeable batteries, positive and negative.

Then the battery charging is carried out in two stages: the first stage is charged until the lithium battery electrolyte releases bubbles, and a single working voltage reaches the line. Then the current will be reduced to 1/2 of the initial current, and the lithium battery electrolyte will release strong bubbles again, and the working voltage will not change for 3 hours. All batteries are charged for about 45-65 hours.
