Summary:

Lead-acid batteries have the advantages of low price, reliable power supply, stable voltage, etc., so they are widely used in defense, communications, railway, transportation, industrial and agricultural production departments. In recent years, the fully sealed maintenance-free lead-acid battery has the advantages of good sealing, no leakage, no pollution, etc., which can ensure the safety of the human body and various electrical equipment, and does not require any maintenance during the whole life, thus uncovering the lead-acid battery. A new page in the development process. As we all know, communication equipment generally uses maintenance-free batteries as backup power. Many uninterruptible power supply systems (UPS) for electronic equipment are also inseparable from maintenance-free batteries. In addition, more and more are used in emergency lights, automobiles, and yachts. Maintenance free battery. However, due to the incorrect charging method, the charging technology cannot adapt to the special needs of the maintenance-free battery, making it difficult for the battery to reach the specified cycle life. Based on this, this paper proposes a smart charger design for a fully sealed maintenance-free lead-acid battery. It uses an advanced three-stage charging control method to effectively improve charging efficiency and extend battery life.
