Across the country, groups of academics from 15 other universities are in the midst of a four-year project, dissecting an electric vehicle and locating tactics to make it even better. The program, called the EcoCar EV Challenge, was founded more than 3 decades ago. through the U. S. Department of Energy. It is run through the DOE’s Argonne National Laboratory.
For more than 35 years, more than 30,000 scholars from 95 universities have participated in the EcoCar Challenge, part of the DOE’s Advanced Vehicle Technology Competition. Each segment spans four years, with the recent peak cycle in 2023 with a new Cadillac Lyriq unveiled by automaker General. Engines.
Students take this festival very seriously, as participation brings many benefits, adding the option of a lifelong career.
One of the organization’s goals is to challenge groups to “identify and address challenging situations equitably in the long-term of mobility through the application of cutting-edge hardware and software solutions” while working with underserved populations. Through this process, student-led groups are finding untapped prospects for the future development of electric vehicles and finding solutions that can benefit local and national communities.
The entire first year is filled with intense study and planning. Students can’t even get a car until sophomore year; During this time, they are taught to work together and speak as a team. They run simulations with propulsion controls and modeling, and the moment they have access to a vehicle, they can dive into it.
Corban Walsh, a student at the University of Alabama, explains that during the prototyping process, automakers like Cadillac end up with a fleet of pre-production cars that can’t be resold. Walsh and his team won a virtually new, all-electric Lyriq with just 17,000 miles (27,400 km), and decided their goal was to move from a rear-wheel-drive setup to an all-wheel-drive setup and increase power from 300 to 550 (223 to 373 kW). With responsibilities like that, you’d think it’s an ideal club for car enthusiasts. But Walsh says the team has varied interests and is really very focused on software and planning.
“In a way, we appeal to the ‘car enthusiast’ type of person, but in the end you don’t have to be a car enthusiast,” Walsh says. “Sometimes you can even be a car. “
Any student can sign up for the EcoCar EV Challenge, and the general addition familiarizes you with the tracks and groups you can sign up for. First, make a stop at the lab and watch the required protection videos; Then, they choose a sub-team from the general categories of hardware, integration, and software development. The Connected and Automated Vehicle Capabilities sub-team, for example, integrates sensor hardware and software, bringing knowledge together.
Along the way, small responsibilities lead to great progress. One of the Lyriq’s first responsibilities was to download a blank name and registration as a salvage vehicle to consider it road-legal. Teams dismantle the cars as much as they can, progressing through a series of trial and error. They read any and all textbooks they can get their hands on and consult with their GM mentor when they get stuck.
GM also supplies some parts, allowing academics to order a limited number from the catalog. The university is helping to cover some of the costs, and corporations like American Axle are donating critical parts like engines. Mathworks, founded in Natick, Massachusetts, supplies the simulation software the team wants for planning. Students will also be informed how to use the resources available on campus.
“One of the hardest but also coolest things we worked on was making blueprints for the mounts of two new engines,” Walsh says. “We’ll use the foundry on campus where we can cast those parts. “
The foundry gave the team some great advice, Walsh says, helping them understand how to make brackets that are strong enough to support the engine and won’t cause corrosion. They edited the component in 3D, made a ceramic mold, and then burned the plastic. and let the steel harden.
