Energy Management System & Power and Control Board

OUR STORY

We are a community that aims to make the most efficient vehicles by using alternative energy sources for a sustainable world and future generations. Our club, which was founded by Yıldız Technical University students, continues its activities with the intense work of students from different disciplines. Our team, which set out with the slogan "Save Your Energy", aims to add value to the world both technically and socially.

The AESK team participates in national and international competitions in line with its goals and objectives. Our vehicles produced by our team took part in Formula G and Efficiency Challenge competitions organized by TÜBİTAK. These vehicles, which work with solar and electric energies, have achieved a great success by getting degrees from the competitions.

Our team, which always aims for the better, continues to work with great enthusiasm and devotion.

In this process, JLCPCB has been one of our supporters in reaching our goal.

The 'Efficiency Challenge' is an event related to the races held in the Electromobile and Hydromobile categories and vehicles powered by electricity and hydrogen energy. In this way, it is aimed to increase domestic production, to enable university students to research alternative energies, to follow the developments in the world and to gain experience.

This designed system is used in vehicles competing in the hydromobile category. Vehicles in the hydromobile category have 2 energy sources; battery and fuel cell. TÜBİTAK requires teams to use 50% - 50% of these 2 energy sources during the race. The Energy Management System shares the power between these two energy sources. At the same time, the fuel cell channel works as a DC-DC Boost Converter. The battery side is transferred directly to the output.

Power board is a Dc-Dc Boost Converter circuit. The 2 voltage sensors on it measure the fuel cell and battery voltage levels. It measures fuel cell, battery and output currents with 3 current sensors. These measurements are carried to the control floor by headers.

To drive 2 mosfets on the card, mosfet driving cards called gate drivers are used. Again, the relevant signals are transferred from the processor to the power card via the control card.

First, the parts were defined by the electrical department and the design of the board was made.

They designed a board using Gerber. Once everything was put up together, we just had to upload it on JLCPCB's website to have it made custom. You can easily order your PCB from https://jlcpcb.com/RAT also order SMT onr website (Demo page for how to order SMT https://cart.jlcpcb.com/quote?fromDemo=yes&_ga=2.63043887.1673064976.1646718183-909480296.1646359782) You can watch this short video to see how this service process.( https://www.youtube.com/watch?v=pyz-kjLpZa8

To conclude, we want to give a huge thanks to JLCPCB which helps us a lot during theses challenging times. They made the discussion very easy and helped us make this PCB in no time.
