Latest Patents

Kenneth F Gerken holds a patent for a "Method and apparatus for controlling battery charging current." This invention features an automatic photovoltaic controller that provides a fixed frequency, pulse width modulated charging current to charge and regulate a battery. The system controls the duty cycle of the charging current based on the difference between the sensed battery voltage and a desired regulated voltage. Modulation is achieved by managing the on and off states of multiple parallel-connected FET switches placed in series between the photovoltaic array and the battery. The duty cycle can be adjusted in discrete steps from 0% to 100% and is updated frequently with new battery voltage measurements to ensure precise regulation. The charge current pulse rise time is designed to match the response time of the photovoltaic array. The fixed frequency of the charge current operates within the preferred range of 100 Hz to 600 Hz, allowing sufficient time for the chemical reactions within the battery cells to be completed between charge pulses. Additionally, the controller features automatic protection mechanisms that rapidly disconnect the battery and/or load under specified conditions. The photovoltaic array is also disconnected from the battery at night to prevent battery discharge into the array. Equalization of the battery occurs automatically at a voltage level slightly higher than the regulated voltage after a predetermined number of days or if the battery voltage falls below a certain threshold.
