This week, members of the electrical team have made significant progress toward completing one of the more complicated systems being developed for Sunswift IV.
The Battery Monitoring System (BMS) is designed to keep track of the voltages and temperatures of each cell group in the 25kg battery pack being put in Sunswift IV. This involves producing 33 identical monitoring circuits, each with their own microprocessor and protection circuitry.
With years of expertise, Dave Snowdon (pictured left) helps relative newcomer Alex Boulgakov (pictured right) to design the software that will run this monitoring system. With 33 boards to manufacture, we are using a soldering technique called reflow: it uses a mask, solder paste and a workstation to allow soldering of all the components on a single board at once, thus decreasing manufacturing time significantly.
With the help of the battery monitoring system, the team hopes to use the battery in the most efficient and safest way during the upcoming 2009 World Solar Challenge...." style="float: left; padding-right: 5px; width: 175px; height: 117px;" />This week, members of the electrical team have made significant progress toward completing one of the more complicated systems being dev...
While the mechanical systems for Sunswift IV are presently the team's main focus, the electrical wizardry that has won the team so many awards is being polished and fine-tuned. One particularly important component are the team's Maximum Power Point Trackers (MPPTs). These devices will connect Sunswift IV's solar panels to it's small battery and motor controller. The devices allow the car's small battery to charge, while simultaneously allowing the solar panels to run at their optimum voltage.While the mechanical systems for Sunswift IV are presently the team's main focus, the electrical wizardry that has won the team so many awards is being polished and fine-tuned in preparation for t...
Today we were visited by Simon Pullinger and Amy Szypica from RS Components. RS has generously donated all kinds of equipment and components that will make an enormous difference in the construction of Sunswift IV, and to the team's student members in years to come. Highlights of their donation include a new digital oscilloscope, multimeter, milling tools, toolboxes, heatshrink and glues.
Not only did RS give us these fantastic, high-quality tools, they also gave the team members knives, coffee cups and all kinds of other goodies.
It is a wonderful contribution to our team, and we look forward to working with RS Components for our electronic and mechanical component and tooling needs in the future. - The new battery cells for Jaycar Sunswift III have arrived!
