  • Solar battery charging controller
    Patent number: 8519678
    Abstract: Battery charging circuitry is provided. A charge controller receives electrical energy from a photovoltaic panel. A first timer provides a stream of clock pulses. A second timer is triggered by the clock pulses and generates a pulse-width modulated (PWM) signal. A duty cycle of the PWM signal is determined by way of comparing a time-varying capacitor voltage to a signal derived from a storage battery voltage. Transfer of electrical energy from the photovoltaic panel to the storage battery is regulated by a shunting element using the PWM signal.

  • SOLAR CHARGE CONTROLLER WITH TIME-VARIABLE CHARGING STATES AND TIME-EQUAL SHUNTING STATES
    Publication number: 20130093380
    Abstract: Solar powered battery charging circuitry is provided. A charge controller receives electrical energy from a photovoltaic panel. Timer circuitry provides a control signal. A duty cycle of the control signal is determined by way of comparing a time-varying capacitor voltage to a lesser threshold voltage and a greater threshold voltage. The control signal is characterized by time-variable charging states and time-equal shunting states. Transfer of electrical energy from the photovoltaic panel to the storage battery is regulated by a shunting element using the control signal.
