Lead-acid batteries are widely used in electric power, communications, data centers, finance, rail transit, high-speed and other industries. They are the equipment with the shortest life, the longest usage time, and the equipment with the highest cost. The lead-acid battery itself has the problem of imbalance. The lead-acid battery consists of up to 36 monomers. The more battery monomers, the more unbalanced. A problem with a single battery will cause problems with the entire battery pack, and shorten the battery life. service life. How to deal with the unbalanced battery voltage, how to balance the lead-acid battery pack? Let me give you a detailed introduction.
How to balance the voltage of lead-acid battery pack
Due to the difference of the batteries themselves, if they are used in series for a period of time, there will be differences, mainly in the different voltages of the batteries, ranging from tens of millivolts to a few tenths of volts, and the battery must be balanced to play the role of the battery pack; for As far as the battery pack is concerned, the charger cannot realize the balanced charging of the battery pack connected in series. The best way is to use a lead-acid battery equalizer.
Using a charger to charge a group of batteries connected in series cannot guarantee the balanced charging of each battery in the battery pack, often due to the voltage change (higher or lower) of some batteries in the battery, other batteries are overcharged or undercharged . The battery packs are connected in series, and the batteries with weak performance determine the performance of the whole pack of batteries. In order to solve this problem, the state stipulates that regular (720H) strong charging is adopted, and the backward batteries in the battery pack are charged by increasing the charging voltage of the whole pack. Perform compensatory charging.
Using the method of increasing the charging voltage of the whole group to charge the battery pack can restore the capacity of the lagging battery, but it will also charge the good battery to failure, resulting in a decline in capacity, shortened battery life, and dry electrolyte, which will affect the reliability of the entire system operation. . However, the existing monitoring methods cannot monitor the operation status of the battery from the three indicators of voltage, internal resistance, and capacity, accurately judge the quality of the battery, and pick out outdated batteries. The stability and reliability of the battery cannot be guaranteed.
Battery Equalizer Product Introduction
The battery balancer, also called the battery balancer, is an electronic protection device that prevents the voltage imbalance between the cells inside the battery from reducing the service life. When the voltage between the battery compartments is unbalanced, the charging and discharging speeds of different battery compartments are different. When one battery compartment is fully charged, the other battery compartments are in the state of overcharging or undercharging, and overcharging or undercharging will damage the battery and cause the battery capacity to drop. Shortened lifespan. The battery balancer can ensure the power balance between each battery compartment in real time, thereby prolonging the service life of the battery by 5-30%.

Our battery equalizer is an active equalization system developed with great concentration for many years. It solves the charging and discharging equalization problem of battery packs such as electric forklifts, electric vehicles, and electric tractors, and effectively prolongs the mileage of battery life and the service life of battery packs.
Therefore, to balance the battery and keep the battery in a normal operating environment is to improve the same working condition of each battery and solve the problem of unbalanced battery cells during operation; at the same time, online activation of batteries with weak performance , greatly prolonging the service life of the battery; providing online battery internal resistance and capacity detection, accurately judging the quality of the battery, and improving the reliability of the battery pack. It fundamentally solves the problem of unbalanced battery packs, makes the operation of the battery packs stable and reliable, and fully guarantees the normal operation of the power supply system.
