In the new energy era, lead-acid batteries and lithium battery packs are widely used in electric vehicles, solar energy storage, UPS uninterruptible power supplies and other fields. However, 80% of battery pack failures are caused by unbalanced battery voltage! How to solve this industry pain point? Battery equalizers are "smart stewards" to improve battery performance. This paper will deeply analyze its working principle, core functions and purchase points.

Why do I need a battery equalizer?

Lead-acid/lithium battery packs are composed of multiple monomers in series, due to manufacturing process, temperature differences and other factors, each single battery has a natural inconsistency. Long-term use can cause:

1. Some batteries are overcharged during charging, causing a bulge

2. Overdischarge of weak current monomer accelerates damage

3. The overall capacity is reduced by more than 30%

Battery equalizer, also known as battery balancer, is an electronic protection device that prevents the voltage imbalance between battery cells inside the battery from reducing the service life. When the voltage imbalance between battery cells, different battery cells charge and discharge speed is different, a battery cell is charged at the same time, other battery cells are in the state of overcharge or undercharge, and overcharge or undercharge will damage the battery, resulting in reduced battery capacity and shortened life. The battery equalizer can ensure the power balance between battery cells in real time, thereby extending the battery life by 5-30%.

Second, the five core technical advantages of battery equalizer

1. Extend service life

2. Reduce battery replacement

3. Maintain charge balance

4. Save on extra expenses

5. Insulation components, sealing design

Third, how to choose a high-quality battery equalizer?

Matching battery type: lead acid, lithium iron phosphate, ternary lithium need to correspond to the special model

Balanced current selection: more than 50A is suitable for industrial and commercial energy storage, 5-20A is suitable for household scenarios

Brand technical strength: The preferred choice of ISO9001/CE certified manufacturers

After-sales service guarantee: Provide product quality assurance, support technical remote diagnosis

Lham Battery Equalizer is a lead-acid battery active balancing system developed for many years to solve the problem of balanced charging and balanced discharge of electric forklifts, electric vehicles, electric tractors and other battery packs, effectively extending the battery range and battery life.

Fourth, the application prospect of battery equalizer

In the field of electric vehicles, battery equalizer has become standard. It not only improves the range of the vehicle, but also ensures the safety and reliability of the battery pack. With the popularity of electric vehicles, the equalizer market will usher in greater space for development.

In the new energy storage system, the battery equalizer plays a key role. Large-scale energy storage power stations need to manage thousands of battery cells, and the equalizer can ensure the stable operation of the entire system, improve energy storage efficiency, and reduce operation and maintenance costs.

With the advent of the 5G era, communication base stations have increasingly high requirements for backup power. The battery equalizer can ensure the reliability of the backup power supply of the base station and provide guarantee for the stable operation of the communication network.

The development of battery equalizer technology marks that the battery management system has entered a new era of intelligence. It not only solves the key problems in the use of battery packs, but also provides important support for the development of the new energy industry. With the continuous progress of technology, battery equalizer will play an important role in more areas to promote the continuous improvement of energy efficiency. In the future, more intelligent and integrated equalizer products will appear, making greater contributions to the construction of a clean and efficient energy system.

Conclusion: Choosing a quality battery equalizer is the equivalent of equipping your battery pack with a "general practitioner." Whether it is industrial and commercial energy storage systems or household new energy equipment, the scientific application of balancing technology can reduce maintenance costs by more than 30%.
