Is the lead-acid battery charging and heating normal?

The reasons for the heating of the battery pack are: 1. Current control, 2. Large internal resistance of a single battery, 3. Ventilation of the battery charging room, 4. Overall battery vulcanization.

The internal resistance of the battery should be reduced after charging; you can accurately measure the internal resistance of the rechargeable battery, which is undoubtedly much smaller than the internal resistance of the rechargeable battery.

Battery charging should be a large current, because the battery has a certain internal resistance, so it will be converted into heat, which is difficult to release quickly, because the battery is generally a plastic case, so the temperature of the battery will increase Come higher. Reduce the current and the level will decrease a lot.

What is the function of the maintenance-free battery electric eye?

The eye position on the bottle is generally on the negative left side, the bright red plastic cover on the left side is positive, and the exposed lead on the right side is negative.

There is no plastic oil plug on the top of the maintenance-free battery, so except for the technical professional battery repair unit, general users cannot regularly check the lithium-ion battery electrolyte. In order to allow customers to control the battery at any time and place, the maintenance bottle is generally equipped with an eye, and the inside of the ball can be seen in all ordinary light sources. Green means everything is normal, black means it must be charged, and white means lithium battery electrolyte or battery is ineffective for a long time. replace. The non-maintenance bottle also has steam discharge in the application, so a small exhaust port is provided on its side. However, when the battery cannot be recharged to a reasonable output power level due to the arrival of the service period, the battery is a real sense of reactive power and must be switched.

What is the difference between UPS power supply and regulated power supply

In the actual operation of battery charging and discharging, such as choosing offline applications for battery charging and vacation, not only Installation is difficult and unsafe. In order to ensure the safety and rationality of the charging and discharging experiments of the charging and discharging batteries, we can not only find problems (external batteries, reverse charging batteries, etc.), but also ensure the safety and reliability of the power supply system (not causing overcharge and discharge, short circuits) Failure, power system termination, etc.), we strongly recommend a method to use the load to charge and discharge instantly, that is, turn off the ups communication button of the power switch to allow the battery to charge and discharge. What to do if the bottle encounters one of the above situations: When the bottle cannot start the car, it is usually said that there is no electricity.

Since the rising switching power supply is mainly used in key communication networks and other system software, the load changes little, so the load is charged and discharged immediately, and its charge and discharge current basis will not change, so it can be based on the battery's working voltage Clear the charging and discharging stop working voltage with the charging and discharging state, calculate the charging and discharging interval, compare the charging and discharging of the next quarter with the record, and immediately eliminate the problem.
