Project Summary

In order to promote green energy and sustainable energy goal, the charging of EVs should also be from renewable sources like solar power etc, otherwise, the generation of electricity from coal-based or oil-based plants doesn't achieve the goal in a true manner. In order to meet the real green energy concept, a solar-powered e-bike charging station is proposed in this project that can charge e-bikes. The charging station offers cost-effective features, such as battery storage, which allows both grid-connected and off-grid operation. Our concern is to provide economic benefits to Pakistan's industry. Without the use of an AC charging adaptor, DC charging utilises the DC current from the photovoltaic panels to charge the e-bike battery directly. The charging station is a facility for charging E-bikes that offers optimum convenience to the user, as well as a smart IoT interface on a mobile device to track usage like charging percentage, price, voltages, etc.

Project Objectives

Our focus is to provide affordable charging facility to Pakistani community and to overcome the energy crisis with the user-friendly innovative charging station.

Key objectives include:

1) Design of high-frequency transformer.

2) CC/CV (constant current, constant voltage) design.

3) The controller's design.

4) IoT base system implementation.

5) The final stage is the combined stage.

Project Implementation Method

Initiation

In this project, we are designing a solar base smart e-bike charging station. We first describe the datasets and methodology used for our data driven analysis followed by our results. The system works directly with solar as well as grid supply and charge the batteries of the e-bike.

Planning:

A Solar Charge Controller works by regulating the voltage and current flow from solar panels to a battery. It detects and monitors the battery voltage, reducing the current when the battery is fully charged. The controller maintains a float charge to keep the battery ready for use. Similarly, battery charged with the external DC source is applied to the battery.

Execution: 

A Solar Charge Controller works by regulating the voltage and current flow from solar panels to a battery. It detects and monitors the battery voltage, reducing the current when the battery is fully charged. The controller maintains a float charge to keep the battery ready for use. Similarly, battery charged with the external DC source is applied to the battery.

Although batteries can only be charged with DC power, most electric bikes have an onboard AC-to-DC converter that allows them to be plugged into a standard household AC electrical receptacle. This project with an inexpensive low-power public charging station will also provide AC power, also known as an "AC charging station." To facilitate higher power charging, which requires much larger AC-to-DC converters, the converter is built into the charging station instead of the e-bike, and the station supplies already-converted DC power directly to the e-bike, bypassing the e bike's onboard converter. These are known as "DC charging stations." Most fully electric bike models can accept both AC and DC power.

Monitor and control:

The proposed block diagram is given as:

Solar panel – Charge Controller – Switching – CC-CV

Grid – AC-DC – Chopper – Switching Circuit – Controller 

In our project, the e-bike charging station is linked with the grid and solar panels. We monitor the charging of batteries, price and other factors. A charging station, or electric vehicle supply equipment (EVSE), is a piece of equipment that supplies electrical power for charging plug-in electric bikes and is used to charge batteries with either grid or solar power.

Final stage:

The final stage of our project is a method to ensure that the battery is not being over-charged. This can be done by accurately maintaining the low absorption voltage level. Our focus is to make charging stations that provide connectors that conform to a variety of standards. DC charging stations are commonly equipped with multiple connectors to be able to supply a wide variety of electric bikes.

Benefits of the Project

This project is implemented with multiple benefits. These savings quickly add up, and are prove to be sustainable for Pakistani community with driving of E-bike.

Key benefits of charging stations include:

1. Reduce transportation cost from high petrol prices.
2. Improve mileage by providing charging facilities at different places.
3. Support a green business initiative by reducing your carbon emissions.
4. It is helpful to promote a local industry.

Technical Details of Final Deliverable

• The designing of high frequency transformer

These transformers are designed to handle more volts safely and accurately, converting high voltage and current levels between coils by magnetic induction. This was designed by calculating the turn ratio, core parameters, core structure, and assembly of the transformer.

• Multistage CC/CV charging method:

The charging process is analysed by the electrochemical Li-ion battery model and the first-order equivalent circuit model. The increase in internal resistance is the main limitation of charging capacity at low temperatures. The proposed multistage CC-CV strategy can extend the constant current charging process to obtain a larger capacity by decreasing the charging rate when the terminal voltage reaches the cut-off voltage.

• IOT Base network:

IoT can also be applied to EV charging stations, making them much smarter. Connecting charging stations IoT offers easier maintenance and management of charging devices with user-friendly remote control and management. It provides the possibility of calculating price, voltages, current, and multiple features.

Result:

A single solar panel per station is capable of meeting the entire annual charge demand of the station, implying that net-zero operation can be achieved in a modest investment cost of a panel per station.
