  • METHOD AND SYSTEM FOR CHARGER ADAPTIVE VOLTAGE REGULATION
    Publication number: 20240088690
    Abstract: Systems and methods for adaptive voltage regulation are described. According to an example, a method for operating a charger may include setting, by a charger controller of the charger, a maximum regulation voltage threshold and a minimum regulation voltage threshold, the minimum regulation voltage threshold being a predetermined percentage of the maximum regulation voltage threshold, the predetermined percentage ranging from between about 90% and about 98%; setting, by the charger controller, a charger regulation voltage to the maximum regulation voltage threshold; determining, by a battery monitor, a state of charge of a battery module; and operating the charger at the maximum regulation voltage threshold until the battery module is maximally charged.

  • Over voltage and over current protection integrated circuit
    Patent number: 8232772
    Abstract: An integrated circuit is disclosed including a primary input for receiving an input voltage, a battery voltage input for receiving a battery voltage signal and an output for providing an output voltage higher than the battery voltage. First circuitry responsive to the input voltage is provided for turning off the output voltage responsive to an input over voltage condition. Second circuitry responsive to the battery voltage signal is provided for turning off the output voltage responsive to a battery over voltage condition. Third circuitry provides for over current protection.
