CPU 2015-7: Design and Development of Automatic Battery Charger with Controller for Battery Charging Station

The study aimed to design and construct a locally-made battery charge controller for the Battery Charging Station (BCS) project implemented by Central Philippine University-Affiliated Non-conventional Energy Center (CPU-ANEC). The battery charge controller was designed only to protect the battery from over-charging. The functionality of the charge-controller was tested using a solar panel and a battery. The charging current was controlled by the PWM circuit. During charging, the output of the PWM circuit was both set approximately to ten percent (10%) duty cycle for charging ninety percent (90%) duty cycle for trickle charging. The output waveform and the duty cycle of the PWM circuit were checked using the oscilloscope. Testing of the charge-controller was done for four days of continuous operation to ensure the reliability of the system. Based on the test results, when the duty cycle was ten percent (10%), the green LED lighted-up and the ammeter indicated maximum charging current, while for the ninety percent (90%) duty cycle, a yellow LED light-up indicating minimum current. The red LED lighted up when the polarity of the battery was reversed, while the orange LED lighted up only when the battery state of charge was empty. These test results show that the battery charge-controller worked as expected by meeting the required design parameters.
