Analysis of new measures for winter battery maintenance

A new winter battery maintenance method battery maintenance is low in winter, and the activity of active substances in the battery is lowered, and the use is slow, and the discharge cannot be out, and the discharge efficiency is lowered. In general, the power of the battery will fall by about 40%. When the outdoor ambient temperature is 5 ° C, the discharge power can be only 50-60% of normal temperature (25 ° C).

In addition, the battery uses more cycles or longer longer to lose more power. The maintenance of the battery says that the daughter wants to have a good time, the battery is also very common. The battery determines whether our work can be used normally, so you have to check the battery regularly, replace it in time, maintenance.

There is a sentence in the industry: the battery capacity temperature is 25 ° C, the temperature drops 1 ° C, the battery capacity drops by 1%. When the battery is at a low temperature environment, the cycle capacity is low, the viscosity of the electrolyte increases, and the chemical reaction resistance is increased. During the same charging time, the amount of charge in the 5 ° C environment is only 70% in the 25 ° C environment.

Battery maintains a good battery for winter, suggesting pets in batteries 1. Check if the outer box is damaged. If there is a deformation or damage, open the box to confirm whether the battery is damaged or deformed; check if the battery meets the specified standard.

When entering the warehouse, please clearly indicate the type, specifications, date of the incoming material, so that advanced first-end management, identify products for long storage time. The battery is in use 1. The normal voltage of the battery is 3.

3V-4.2V. The battery should be controlled within this range; before charging and disculating the battery, it is recommended to test the voltage of each battery first.

The battery voltage is about 3.8V within 1 month after delivery, and the voltage difference of each chip is within 20mV. With the medium battery pack, the battery pressure difference ranges from 100mV; 2.

The maximum limit voltage capable of the battery is 4.2V, the minimum limit voltage is 3.0V.

When the battery voltage is higher than 4.2V or less than 3.0V, the charging and discharge performance and safety performance of the battery can be damaged, resulting in a battery heat, air leakage, and airflant.

Preventive measures of battery maintenance discharge: The discharge temperature range is 10 ~ 45 ° C, and the maximum current must not exceed the specification requirements. Battery bulging, deformed, leakage or voltage difference≥100mv does not allow discharge; discharge lower limit voltage must not be less than 3.2V, the surface temperature of the battery is not higher than 80 ° C after the battery high current discharge.

Battery maintenance attention to the storage of batteries 1. Pay attention to keep the warehouse dry, clean, not crowded. It is best to maintain a space between 0.

5-0.8m; at the same time, there must be a duty, the warehouse staff must have a high fire prevention; the warehouse should be equipped with: fire sand, asbestos, asbestos gloves, 坩 坩, mask. 2.

In the transportation process, the battery should also be supplemented and take anti-collision measures. The prevention of battery is severely impacted or vibration; if there is any abnormal characteristics of the battery, such as the battery plastic blocking, the outer shell is damaged, the electrolyte has an odor, electrolysis Liquid leak, do not use, battery electrolyte leaks or emit electrolyte odor should be far from the fire source to prevent danger. The maintenance of the battery is not doing 1.

Non-professionals do not anatomy the battery, otherwise it will cause internal short circuits, and cause safety issues such as gas, fire. 2. In theory, there is no flow electrolyte in the lithium polymer battery, but if the electrolyte leaks and contacts the skin, the eye or other parts of the body, it should be rinsed with water immediately and immediately prepare it; 3, do not burn the battery in any case Or put into fire, otherwise it will cause battery burning, which is very dangerous, absolutely prohibited; do not allow cells in liquid, such as fresh water, sea water, beverage (juice coffee, etc.

). Pad reminder: Maintain your battery when it is cold, but also pay attention to yourself!.
