Description

Technical Field

[0001] The present invention relates to the technical field of lead-acid batteries, and in particular to an intelligent charging device and method for lead-acid batteries. Background Art

[0002] Lead-acid battery is a secondary battery, rechargeable battery, rechargeable battery and primary battery. It is an acidic storage battery with metallic lead as electrode and manganese dioxide or nickel sulfate as positive electrode active material. Its voltage is two volts (v), so it is commonly known as "battery". Its working principle is: the positive electrode (PbO2) and negative electrode (Pb) in the lead-acid battery are immersed in the electrolyte (dilute sulfuric acid), and 2V of power will be generated between the two electrodes. After charging and discharging, the anode, cathode and electrolyte will undergo corresponding changes.

[0003] The existing lead-acid battery charging methods all use a fixed single output voltage (48V or 60V or 72V) and two-stage constant current charging. The charging completion is determined based on the charging time of the second stage. In addition, the mains voltage fluctuates too much, leading to undercharging or overcharging. Long-term undercharging or overcharging can easily cause the battery to be scrapped. Therefore, we propose an intelligent charging method for lead-acid batteries. Summary of the invention
