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.

Commercial power supply is not capable of providing clean and consistent electric power demanded by sensitive equipment. Sensitive equipment requires a consistent supply of power of the correct specifications for their operation, hardware protection, continuity of process, storage and transfer of information, and safety of personal Computer network communication links, electronic medical equipment, industrial process control, remote installations like offshore operations, online applications such as airline reservations etc., are examples of such critical loads. Beyond any dispute, the installation of an Uninterrupted Power Supply (UPS) system is now days accepted as being a vital element in the protection of sensitive equipment.

BATTERY-LIFE OF THE UPS SYSTEM:-

The most critical part of the UPS system is the battery. The battery often represents half the original cost of   UPS system. It is the weakest link in the UPS system. An incorrect selection of the battery type may reduce the initial cost but would adversely affect the overall life of the system.

The battery life is determined by the UPS service conditions. For online UPS systems, the battery remains on floating charge for longer time. Float performance characteristics has a strong influence on battery life.

Prolonged breakdowns can cause the battery to deep discharge several times in a week if not in a day.  This in turn affects battery life drastically, as a thumb rule; a deep discharge below 80% battery capacity reduces the life of the battery by 25%.

In daily production and life, we often need to know the temperature and humidity value of the certain place If we use cable to transmit data, it will cost a lot, but the wireless communication costs less, it establishes a connection between the buildings in a very short time, and error rate is quite low. Therefore, in the environment which cable can’t be used, the wireless communication is more practical. And if the receiver is made into hand-held, the flexibility will increase greatly.

The whole controller of the project is Arduino microcontroller. In this project DHT11, Wi-Fi module, light, fan and relay are interfaced to microcontroller. Here, temperature and humidity are monitored and controlled using Android mobile. The data of DHT11 is send to android mobile through Wi-Fi module. The controlling of parameters is done using some devices to be ON/OFF from Android mobile. If Temperature is high the DC fan is ON through relay to reduce temperature. If humidity is low the light is ON through relay to decrease moisture level.

1. Arduino microcontroller
2. RPS
3. DHT11 sensor

Accelerometer is an electromechanical device that measures acceleration forces. These forces may be static, like the constant force of gravity pulling at our feet, or they could be dynamic – caused by moving or vibrating the accelerometer. MEMS accelerometers are one of the simplest but also most applicable micro-electromechanical systems. They became indispensable in automobile industry, computer and audio-video technology.

This project makes use of a Relay switch for switching the devices. The Microcontroller decides which device to be operated from the input it gets through the body gestures (MEMS Accelerometer sensor). The Microcontroller is loaded with an intelligent program written using embedded ‘C’ language.

This proposed system provides a solution that ensures safety of maintenance staff, i.e., line man. The control to turn on/off the line will be maintained by the line man only because this system has an arrangement such that a password is required to operate the circuit breaker (on/off).

This system is fully controlled by ARDUINO NANO microcontroller. A matrix keypad is interfaced to the microcontroller to enter the password. The entered password is compared with the stored password in the ROM of the microcontroller.

If the password entered is correct, then only the line can be turned ON/OFF. The activation / deactivation of the circuit breaker is indicated by a lamp that turns on or off. The status will display on LCD.

The features of the project are: 

• Password based circuit breakers control.
• Key pad-based password access.
• Usage of relay to break the circuit.

The major building blocks of this project are: 

• Regulated power supply.
• ARDUINO NANO Micro-controller.
