The objective of this project is to charge the EV battery and supply the household load uninterruptedly irrespective of any disturbance.   In this project, an implementation of solar photovoltaic (PV) array powered grid connected, residential electric vehicle (EV) charger is presented, which caters the need of an EV, household loads and the grid. The charger is enabled to operate autonomously using a PV array for providing an uninterruptible charging and power to household loads. However, in the absence of the PV array or insufficient PV array generation, the grid connected mode of operation is presented.   In This project we are using multiple methods to charge the EV battery and to give the power supply to the house loads; one is bi-directional ac-dc conversion using grid and second one is dc-dc conversion using solar.    

Main features of this project:  

1. Use of Renewable energy solar.
2. By using this project, we can give the uninterrupted power supply to the loads.
3. Automatic switching of modes.
4. Low power consumption.
5. Controls high and low voltage devices.

  The major building blocks of this project are:

• Solar panels.
• Capacitor bank
• DC-DC bidirectional Circuit
• DC-AC bidirectional circuit.
• EV battery.
• Home appliances
• GRID.
• LED indicators.
