Todd La Londe, director of relays maker Churod Americas, recently contacted Battery Technology to share news about The University of Michigan’s MRacing team, which his company sponsors.
“The team had an outstanding finish in the 2022 Formula SAE EV competition held in Michigan in June,” La Londe reported.
The 2022 competition pitted electric open-wheel race cars from 58 universities. MRacing finished a remarkable second place, just behind Ecole Polytechnique Montreal. Further, the Michigan team placed first among US-based schools for the fourth year in a row. The team placed third place overall in the design category, receiving glowing praise from the judges for having the best powertrain in the competition.
Introduced in 2013, Formula SAE Electric allows the development of fully electric vehicles within the FSAE framework. Teams use vehicles powered only by electrical motors and compete in static and dynamic events such as design, presentation, cost, acceleration, skidpad, autocross, endurance, and efficiency.
La Londe said that Churod’s support of the MRacing team came in multiple forms, including providing CHEV series hermetically sealed high voltage DC contactors for use in the power management system.
The CHEV worked exceptionally well in the design, according to the team: “We're really happy with how they performed,” stated Nicholas Chan of the MRacing Powertrain Engineering group.
“One issue we've had in the past was with high inrush currents with our contactors affecting our low-voltage systems,” Chan stated. “We've found that the economized coils on the CHEV-112 contactors have no overshoot at all, completely solving this issue.” The contactor provided was rated for 250A at 750VDC, but the CHEV family has solutions for currents from 60A–600A and voltages to 1000VDC.
“We look forward to helping the MRacing team to reach its goals during the upcoming 2023 season and beyond,” La Londe said. “And in the meantime, attendees of The Battery Show North America can see the MRacing team’s award-winning car for themselves at our booth.”
