In recent years, with the need of the development of science and technology, the application of battery is also very wide in all aspects, and the application of battery, but also brought a series of problems, so it is very important to improve the safety and reliability of the battery operation, battery equalizer how to extend the service life of the battery, let’s take a look!
The importance of battery voltage balance
Battery is widely used in the field of uninterruptible power supply and electric power because of its good economy and practicability. With the gradual improvement of the battery manufacturing technology and process, the service life of the battery has been significantly improved, and the battery failure caused by the quality of the battery itself has rarely appeared.
And in the use of the battery in the process of over charging, over discharge, will lead to plate active material loss, plate grid corrosion, seriously affect the service life of the battery. The electrolyte density, temperature and ventilation conditions, self-discharge degree, and charging and discharging mode of each battery pack vary slightly.
After multiple charging and discharging cycles of the battery, the differentiation will gradually become larger, which leads to the inconsistency of battery voltage, internal resistance, capacity and other parameters. It is inevitable that overcharge and discharge will occur, so it is very important to ensure the voltage balance of the battery.
Single battery due to low voltage, in most cases is the battery series group use, even if the same manufacturer of the same batch of models of the battery, also can not ensure that all attributes of each battery are the same, when the battery capacity is inconsistent, some battery overcharge, overdischarge problems, will affect the battery life.
Solution to keep battery voltage balance consistent
Battery equalizer can solve the problem of voltage unbalance.
1. The battery equalizer can compensate the battery bidirectional. When the voltage difference of the series battery exceeds 50mV, the battery equalizer starts to work
2. When the battery equalizer charges the battery in series, the high-voltage battery string charges the low-voltage battery in reverse so that the voltage of the two battery strings is consistent. When the battery string discharges, the two batteries discharge simultaneously.
Battery equalizer, also known as a battery balancer, is an electronic protection device that prevents voltage imbalance among battery cells from reducing the service life of a battery. When the voltage imbalance between battery cells, different cell charging and discharging speed is different. When a cell is charged, other cells are in the state of overcharge or undercharge, and overcharge or undercharge will damage the battery, resulting in reduced battery capacity and shortened battery life. The battery equalizer ensures the power balance among battery cells in real time, extending the battery service life by 5-30%.
LhAM battery equalizer is a lead-acid battery active balancing system dedicated to research and development for many years. It solves the problem of balanced charging and discharge of electric forklifts, electric vehicles, electric tractors and other battery packs, and effectively extends the range of battery life and battery packs.
