2020 Project

BOLT IV is built from a donated chassis and powered using 996 lithium-ion cells. All components have been mounted on the bike, and the team is currently in the process of integrating all of the systems in preparation for spinning the wheel and testing on a dynamometer.

In order to verify power characteristics and choose the specific type of cell, the battery test bench (left) was used to run a race profile on the battery and observe the response. The powertrain subteam then designed battery trays to hold all the batteries in a space-efficient manner and distribute heat well enough for discharging during a race.

As other components were selected, the chassis subteam worked on CAD designs of mounts for the motor, motor controller, battery management system, and other components. These mounts and structures have been machined, and incremental housing upgrades are being made via 3D printing.

The PCBs that will control CAN communication, interfacing with the bike, and internal signals have been integrated with a TI MSP432 microcontroller, which runs a state machine and processes data to transmit. This will allow for remote monitoring of bike characteristics during the race.

The team is currently preparing for its next race.
