Project Summary

Project Information

An Accessory Power Module (APM) is a device that controls, converts and distributes a vehicle’s power from the given high-voltage battery pack to all necessary low-voltage vehicle components. This device must also report any power failures greater than 3 seconds and initiate the backup power system and control the power throughout the vehicle using pre-set detected faults. Currently, the industry offers pre-built APMs that are not compatible with the electric dirt bike, since they are designed for larger vehicles, such as automobiles or aircrafts. Previous revisions of the EVT bike, REV1 and REV2, had used a Low Voltage Subsystem (LVSS) who’s role will be replaced by the APM.

The goal of this project is to approach the design of an APM using an entirely new vehicle platform. This involves building a custom APM for the EVT electric dirt bike that powers all on-board communication and controls electronics, running for 24-hours continuously under maximum load, monitoring power usage, reporting power failures and initiating the backup power system if needed, controlling the vehicles power system based on preset detected faults and having 3-different power modes: power, accessory and off. The expected end deliverables are a functional prototype, all technical and design documentation and EVT specific documentation. The final design and prototype must fit in the usable space of the EVT dirt bike frame. It will be integrated into DEV1 in Spring 2022 and must operate at maximum load for 24-hours to compete at the Arcadia Barkbusters Northeast 24 Hour Challenge.
