High speed chargers and high frequency battery chargers used with AC power utilize two conversion circuit designing methods and the efficiency and performance of chargers have been enhanced by using additional PFC filter safety circuit etc. If a lead-acid battery is charged with a slow charger for general battery sulfuric acid accumulates as a by-product of the chemical reaction which leads to battery performance deterioration. In order to charge such a battery turning it into the state of initial performance a charger which employs high frequency wave is used to prevent performance deterioration. As it is also important to check the battery state at this time to ensure quick charging and prevent performance deterioration we intend to look into various methods of checking the battery state changes in the charger .
