In this paper, a new method of charging and repairing lead-acid batteries is proposed. Firstly, small pulse current is used to activate and protect the batteries in the initial stage; when the current approaches the optimal current curve, the phase constant current charging is used instead, when the voltage is low.
Abstract: Lead acid battery has been widely used in many fields, such as electric vehicles, equipment, railway transportation, communication and so on.
This paper innovatively proposes a resonant composite pulse repair and reuse system for lead-acid batteries in substations. The system innovatively uses resonant pulse repair technology to repair lead-acid batteries in microgrid energy storage systems. The subject is composed of the core chip Cotex-M3 and its peripheral circuits.
There are some problems in lead-acid batteries, such as short service life and decreasing capacity. In this paper, a new method of charging and repairing lead-acid batteries is proposed.
For instance, a 12V battery with a 100 ampere hour (Ah) capacity will reach this density when 25 Ah (300 Wh) or more have been drawn from the battery. At this point, the lead sulfate will begin to precipitate out of solution onto the battery plates, forming a spongy film.
Therefore, researching an intelligent battery management system with repair function is a very concerned issue in microgrid energy storage. This paper innovatively proposes a resonant composite pulse repair and reuse system for lead-acid batteries in substations.
