When the Racing Green Endurance (RGE) team departed from Alaska’s Prudhoe Bay in early July to begin their more than 16,000 mile journey on the Pan-American Highway, they did so in an electric sports car powered, in part, by NI LabVIEW and NI CompactRIO.
RGE is a student-led project at Imperial College London that aims to demonstrate the potential of zero-emission cars. The team partnered with Radical Sportscars to produce the SRZero electric sports car, which is based on the chassis of the Radical SR8, a British supercar that, until recently, held the Nürburgring lap record for the fastest production car in the world. The SRZero uses a fully electric powertrain that can achieve a top speed of 120 mph. The car has a unique twin-motor electric drive system that makes it possible for the car to travel further than any other electric car before needing to be recharged. Based on their collaboration with RGE, Radical Sportscars plans to launch a production version of the vehicle in 2011.
LabVIEW and CompactRIO power the car’s control systems, making it possible for RGE to integrate all the components in the power train. CompactRIO controls the battery management system to monitor and protect the health of the Lithium Iron Phosphate batteries. CompactRIO also manages motor controllers, driver interfaces and the car’s safety systems.
"CompactRIO, powered by LabVIEW, is the brain of the car," said Alec de Zegher, chief control engineer on the project. "The control system we have built using NI tools enables us to tightly integrate and manage all the different systems on the car."
Toby Schulz, the team’s energy and vehicle systems engineer, added, "We chose CompactRIO to run the SRZero because of its powerful, robust and flexible nature, important attributes when building an experimental electric vehicle. With CompactRIO, our control systems can be adapted and expanded at ease. From our experience with Formula Student, we knew using LabVIEW graphical programming and CompactRIO reconfigurable hardware would enable us to rapidly design and iteratively prototype advanced control systems for the car, allowing us to get from initial concept to a full, road-legal deployment in just months."
RGE will drive the car from Alaska to the world’s southernmost city, Ushuaia, Argentina, and if successful, will become the first electric car to travel the entire Pan-American Highway. One of the team’s stops on their journey will be Austin, Texas, during the first week of August for NIWeek 2010.
