Problems solved by technology

[0002] At present, most lead-acid battery chargers on the market use a single constant voltage and current limiting method for charging. Due to the single charging method of the charger, the charging efficiency of the charger is low, the power loss is large, and the service life of the lead-acid battery is also short. Relatively short, how to provide a smart charger with multi-stage charging management to meet the needs of high charging efficiency, low power loss, and long battery life is a problem that needs to be solved at present
