Abstract: There has been a rise in oil and gas use in the 21st century, which has led to issues including global warming, climate change, and a lack of crude oil. As a result of these factors, automakers have been investigating ways to make solar technology more practical. This means that solar electric cars can make good use of rapid chargers. In terms of carbon emissions, electric vehicles (EVs) are regarded as a viable alternative to internal combustion (I-I) motor vehicles. In any event, their true advantages have yet to be clearly shown, but there are several ways to boost their vitality efficiency. When utilizing energy generated by fossil fuels to charge electric vehicles, a significant amount of power is lost. There are a lot fewer benefits to using electric cars than there are to using renewable sources of power.A rapid charger battery/super capacitor is employed in this dissertation. When the super capacitor voltage drops below the battery voltage, the battery may provide power. As a result, the storm’s weight is given a rather uniform distribution. As a result, the necessary power has been delivered to the load using these two energy sources. A super capacitor is employed to give power to the motor at fast speeds because of the coding in these input sources, which selects the requirement for authority at a certain moment for the motor. The output power is often provided by a battery. Solar energy is the primary source of power for this function. Fast charging of Li-ion battery cells may be achieved by delivering continuous current to charge the batteries such that they charge faster than conventional constant voltage charging. To maximize battery charging efficiency, the fast-charging method makes use of the battery management system. Additionally, PWM is regulated using a MOSFET to control the output voltage.
