1. Solar panels generate energy during the day and feed it into the electric grid.

2. The smart charging system monitors the energy generated by the solar panels and calculates the available solar energy.

3. The EV owner sets a preferred charging level and departure time for their vehicle, which the smart charging system uses to schedule the charging session.

4. The smart charging system determines how much energy is required to charge the EV battery to the desired level by the specified departure time.

5. The system then checks the available solar energy to determine how much of that energy can be used to charge the vehicle.

6. If there is enough solar energy available to charge the EV battery to the desired level, the smart charging system uses as much solar energy as possible to charge the vehicle.

7. If there is not enough solar energy available to charge the EV battery to the desired level by the specified departure time, the system will supplement the charging session with energy from the grid.

Overall, smart charging systems offer a safe and efficient way to charge EVs using solar energy while also ensuring that the EV battery is fully charged and ready for use when needed.

1. 10A Power Point: A standard power point typically delivers a maximum current of 10 amps (A). Charging an electric vehicle using a 10A power point is the slowest option. It can take several hours or even overnight to fully charge the EV, depending on the battery capacity and starting charge level. For example, if your electric vehicle has a 60-kWh battery capacity, it will take roughly 25 hours to fully charge from empty using a 10A power point. 

2. 15A Power Point: A 15A power point delivers a higher maximum current compared to a 10A power point. Charging an electric vehicle with a 15A power point is faster than using a 10A power point but still relatively slower compared to dedicated EV chargers. It can reduce the charging time compared to a 10A power point by a few hours. Using the same example of a 60-kWh battery capacity, it would take approximately 16 hours to fully charge the EV from empty using a 15A power point. 

3. 7kW EV Charger: A 7-kilowatt (kW) EV charger is a dedicated charging unit that provides faster charging compared to power points. It operates at a higher power level, capable of delivering up to 7 kilowatts of power. For a 60-kWh battery capacity, it would take approximately 8-10 hours to fully charge the EV from empty using a 7kW charger. 

4. 22kW EV Charger: A 22-kilowatt (kW) EV charger is a higher-power charging unit commonly found in public charging stations. It delivers a significantly higher power level compared to a 7kW charger. With a 22kW EV charger, the charging time for an electric vehicle is considerably faster. For a 60 kWh battery capacity, it would take approximately 2-4 hours to fully charge the EV from empty using a 22kW charger. 

It's important to note that the charging times mentioned are approximate and can vary based on factors such as the specific EV model, battery chemistry, state of charge, and charging efficiency.
