An electric vehicle charging station (EV charging station) is an infrastructure designed for charging electricity for the use of electric vehicles. However, most of
the current EV charging stations still rely on fossil energy sources. Innovation is
needed to overcome this problem. One of them is through the use of solar panels.
The use of solar panels on the CBMS turns it into a clean and environmentally
friendly energy source. However, the energy conversion produced by solar panels
is greatly affected by environmental factors such as weather. Panels that are
covered by trees and tall buildings cause partial shading conditions. Partial
shading conditions can result in a direct decrease in PV output power. To overcome this, output power optimisation using a DC-DC converter is required. The MPPT boost converter system with modified P&O method is designed to maximise the output power of solar panels when partial shading occurs. The test results show that the developed system is able to maximise the output power of solar panels in partial shading conditions with an average power increase of 8.13 and an efficiency of 91%. This method can reduce the negative impact of changes in light intensity, keep the system close to the maximum power point, and improve the efficiency of charging electric vehicles at SPKL during unstable weather conditions. However, the modified P&O method is less effective in maximising the output power in normal
solar panels.
