Abstract
A charge system for series connected rechargeable batteries includes: a power generating unit generating a DC input power based on a voltage input from an AC power source; a charge control unit generating a charge voltage based at least the DC input power from the power generating unit and supplying the charge voltage to the rechargeable batteries through an interface unit; and multiple detecting units each detecting a voltage of a corresponding rechargeable battery through the interface unit, generating a feedback power based on the voltage of the corresponding rechargeable battery upon detecting that the voltage of the corresponding rechargeable battery is within a predetermined voltage range, and outputting the feedback power to the charge control unit such that the charge voltage is generated by the charge control unit further based on the feedback power from any one of the detecting units.
