Both the lithium battery and the solar panels provide electricity to the driving motors of the EV, which is controlled by the vector control algorithm [ 36 ]. The battery pack and solar panels are connected in parallel to provide the electricity to the variable resistant load.
The principle of this algorithm relies on monitoring the reflected input power from the solar panel in the form of charging current as the input voltage is manipulated. Similar to the PO method, this is a hill-climbing scheme that selects the operating point that grants the highest battery charging current.
To maximize the output power of the solar panel, a tracking algorithm must have the ability to monitor input power and adjust load impedance, which typically requires extra circuitry and complex firmware.
