MIT’s Solar Electric Vehicle Team Crosses the Country with RF Modules

Some of the most creative applications of our products come from students. Every year, we are involved with student-led projects that are breaking new ground in industries like automotive, solar power, smart energy, and more. We support these efforts as it leads to insightful feedback on our products and fuels a talented workforce. Here is one of the many projects Digi is helping to support.

The SEVT is a student organization at the Massachusetts Institute of Technology dedicated to designing, building and racing solar powered electric vehicles in long-distance, international competitions. Their upcoming race, the American Solar Challenge, starts in Austin and the team will travel north all the way to Minneapolis.

In order to optimize energy use, the team needs to analyze the car for any environment–especially weather conditions. The ability to monitor numerous data points and adjust accordingly allows the vehicle to cruise at highway speeds, all while consuming less energy than a hair dryer.

The crew is using two XTend RF modules. One module is used to send data to a strategy computer and another connects to the telemetry computer. The strategy computer is used to optimize the energy budget for each day and calculate the velocity that will produce the highest efficiency. The telemetry computer offers an in-depth view into the the car’s entire electrical system that enables the team to identify anomalies and debug problems on board the vehicle. The team’s current vehicle model, Valkyrie, can cruise for two hundred miles on a full battery and with the solar array, it can cruise indefinitely as long as it is under full sunshine.

The American Solar Challenge  starts on July 21, 2014 in Austin. Over the following week, the teams will cross the country and arrive in Minneapolis July 28, 2014. We’ll have a follow-up post after the race. Wish them luck!

Students Innovate with Digi: Formula Buckeyes

Some of the most creative applications of our products come from students. Every year, we are involved with student-led projects that are breaking new ground in industries like automotive, solar power, smart energy, and more. We support these efforts as it leads to insightful feedback on our products and fuels a talented workforce. Here is one of the many projects Digi is helping to support.

The Formula Buckeye SAE Race Team is made up of students from all disciplines. From mechanical engineers, to business, to art students, it’s truly a team effort. The completely student led team must fund, design, build, and test, a high performance racing vehicle that will compete across the country in races with over 100 schools. The car can accelerate from 0-60 in 3.5 seconds!

This year, the team has decided to implement a telemetry project to monitor engine performance and troubleshoot issues. Data is currently stored locally on the car’s ECU and this telemetry project would allow for remote access to these data points. The Digi product being used is an XTend Serial Module. With this module, they are able to read sensor data at a range of more than 15 miles!

Around 20 different sensors are gathering data on the car. They include:

  • Engine Temperature
  • Incoming Air Temperature
  • Vehicle Speed
  • Traction Control
  • Steering Wheel Position
  • On/Off Switches
  • Manifold Air Pressure
  • And More

They plan to create either a Java or Labview application, which will act as a virtual cockpit for the vehicle. The application will display the read outs of each sensor on a computer monitor. This will enable the team to remotely troubleshoot and diagnose performance issues in the vehicle. Future plans hope to accomplish remote control of the engine.

Preparations for the 2014 racing season are underway! Check out their website and Facebook Page for updates.
