First official meeting with Project mentor, Madam Nazreen bt. Junaidi

# data[].attributes.body
During the meeting we:

1. Introduced ourselves.

2. Discuss about relevant theme of the project: "Shaping the future with intelligent solutions."

3. Present out idea which is smart grid. Our mentor decided to decline the idea due to the fact that the project would end up being simulations and no prototype.

4. Decided to brainstorm our ideas again that suits the theme accurately for the next online meeting.

Discuss on our object use for prototype.

We started our simulation with TinkerCad for intial assembling on components. We went through a few problems such as:

1. Output current overload: The arduino's recommended output current has exceed 20mA which can lead to reduced lifetime of arduino. We solved this by replacing the relay switch that controls the transmitter to a nmos mosfet transistor.

2. No display: During the simulation, there is no output of the display text. We still havent found the solution to this problem currently.

We tried few simulation apps then we choose and modify to get the best result.

Apps that we use :

1. Tinkercad

2. Proteus

We presenting our simulation to Mdm Naszreen using Tinkercad and Proteus.Mdm advise us to do a survey on electrical vehicle users about their opinion on wireless charging station. She also asked us to fix the Tinkercad simulation so we can use the simulation for the competition and preesentation.

After days of trial and error, we finally got the result we wanted which to display text on the lcd display. We also added another ultrasonic distance sensor to make it 2 stations.

Review of presentation slide and discussion of project preparation progress with our supervisor

# data[].attributes.body
We presented our initial project idea and draft presentation slides to our supervisor. The presentation included our objectives, proposed system, hardware components, and basic working principle of the solar-powered wireless vehicle charging station.

Supervisor’s Comments and Feedback:

1. Project Objectives Need Revision:

The supervisor suggested that our current objectives were too general.

We were advised to make the objectives more specific and aligned with the actual functionality of our proposed system.

2. Emphasize IoT Integration:

The supervisor recommended that we focus more on the implementation of IoT features, such as remote monitoring and control through a mobile app.

Suggested integrating real-time data logging (e.g., voltage, current, power status) and automatic power management using sensors and Wi-Fi.

Action Plan:

• Revise the project objectives to include clear statements on IoT usage on smart charging management.

• Update the presentation slides with a refined block diagram showing the full system including IoT communication.

• Research suitable IoT platforms (e.g., Blynk or Thingspeak)

During the presentation there were some feedback:

Idea was too ambitious.

The inefficiency of using solar power.

Lack of relevant power value such as; input power, output power, reactive power and active power.

Lack of industrial perspective

We took the feedbacks into account and improve for the next presentation.

Presenting our idea to the industrial judges and as follows are the feedback :

1. We should have a small transformer connected directly from the grid to ensure instant back up when problem occurs to the solar.

2. Improve our simulation especially on the transmitter and receiver because we cannot prove that it was transmit wirelessly in the simulation.

3. Should know how to counter the heating problem with wireless connection.

4. Take note about the induction for the wireless charger.

All the feedback given by the judges was carefully considered. Improvement was made immediately.

# data[].attributes.body
We were asking the ev user to tell about their experience by filling the form and to get some feedback to improve our project on :

1. The real problem that the user face.

2. The charging routine for the ev.

3. How interested the user on this wireless charging system.

4. Seeking opinion on the wireless charging station.

# data[].attributes.body
After almost a weeks of distributing the survey to the ev user, we have gain some feedback from them. From here we could improve things like the problem statement and other major improvement to our project.

# data[].attributes.body
We went to SEDC Energy Sarawak and met with the Assistant Manager Daryll Law where we discussed about the technology involved in EV Charging Stations.

Feedbacks during our visit:

1. For the time being, solar energy is not truly efficient in Sarawak as it only has an average of 4 hours of 100% efficiency of energy.

2. We must take account about the electronics in the car as the electromagnetic waves could affect it negatively.

He helped with providing relevant documents such as past projects documentation to help us during our projects.
