Battery voltage imbalance how to solve

来源:www.hblhnykj.com作者:Hubei Lham时间:2023-03-20

In recent years, the use of electric vehicles has been growing year by year, and many users will encounter this problem. Our electric vehicles are used in series, and the capacity of the battery group is unbalanced after a period of use. There are many reasons for this situation, including production reasons, as well as the reasons and use of raw materials. So how to solve the battery voltage imbalance? Read on.

 

The charge and discharge of two batteries are different due to the difference in chemical composition and temperature. Even when the battery is idle, it will cause imbalance between batteries connected in series due to the degree of self-discharge. During the charging process, due to the existence of differences, one battery will be overcharged or discharged, while another battery will be undercharged or discharged. With the repeated process of charge and discharge, this difference will gradually strengthen, so that the single separator battery replenishment water imbalance, resulting in inconsistent voltage and discharge of the single separator battery, and eventually lead to premature failure of the single separator with excessive water loss, so that the whole battery group is damaged.

Battery voltage imbalance how to solve?


Battery equalizer can solve the problem of unbalanced discharge of battery.

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%.

 

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.

Working principle of battery equalizer

The battery equalizer is an energy transfer equalizer that compensates batteries by both sides. When the voltage difference between batteries connected in series exceeds 60 millivolts, the battery equalizer starts to work and the current flows from the battery with a higher voltage to the battery with a lower voltage to balance the battery. Can be connected in series connected battery for a long time, automatically maintain the balance state of the battery, no maintenance.

 

Battery battery equalizer is suitable for lead-acid batteries, ferric phosphate batteries, nickel copper or nickel metal hydride batteries. When the voltage is higher than 2.4V, the battery equalizer can be used to balance a maximum of four batteries in the range of 2.4V to 12V. If the number of batteries is less than 4, leave the extra connecting cables empty (avoid short circuit of the positive and negative terminals). The equalization effect is not affected. The connection mode of the battery is not limited. The battery can be used in series and parallel without affecting the charging and discharging work of the original equipment.

 

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.
