Power Generation
Power generation is the process of generating electricity from a different source. The source of generation can either be renewable or non-renewable. Since renewable sources are environmentally friendly, they are more preferable to non-renewable sources and are being incorporated into a lot of industry applications. Renewable energy sources like solar and wind are currently the dominant method of generating electricity. These sources also provide an alternative source of energy where access to an electrical grid may be limited or absent, therefore making them vital sources for power generation. Applications of renewable energy range from industrial uses to households and also in automotive vehicles, causing a shift from traditional non-renewable sources.
For this project, a PV panel was chosen at source of power to charge the battery.

Charging Schematic
The algorithm built into the MPPT solar charge controller basically samples the voltage of the PV panel and compares it with the battery voltage. Normally the PV panel voltage only needs to be approximately 14Volts in order to allow current flow into the 12Volt battery and charge it. However, during high irradiance, the voltage level in the PV may reach up to 20Volts at a certain current. In this situation, the DC/DC together with the PWM block adjusts the PV panel output voltage to the level required to charge the battery. Upon adjusting and lowering the PV panel voltage, the current into the battery increases while maintaining the same level of power produced.
