MER19
MER19 at Formula North 2019
MER19
MER19 was Michigan Electric Racing’s first all-electric vehicle, and it placed 2nd at Formula North in May 2019 and 9th at FSAE Electric in Lincoln Nebraska in June 2019. Design began in May of 2018, beginning with lap-time simulations and vehicle architecture decisions. Design Reviews were held in the Fall, and manufacturing began in November 2018. The first drive was completed on April 5th, only a few days after the initial target of April 1st. Testing took place throughout April and May until competition.
Technology
MER19 was powered by two EMRAX 208 PMAC motors, producing a maximum of 420Nm at each rear tire through a 3:1 single reduction gearbox. A Rinehart 100DXR motor controller controlled each motor, and each was connected to the same 6.66kWh 300V battery pack comprised of Samsung 25R 18650 cells in a 72S10P configuration. The vehicle had 3 onboard CAN networks - Body, Powertrain, and Diagnostics, which were presided over by two ECUs, a Pi Innnovo M110 and M220.
Hoosier 18.0x7.5-10 R25B tires were used at each corner, on centerlocking 10” OZ Magneisum wheels. A steel spaceframe held everything together. All together the vehicle weighed 569 lbs.
