PACCAR

Battery Electrical Interface

The E-Truck Challenge began in late 2023 through a partnership with PACCAR to retrofit a Class 7 Peterbilt truck into an all-electric vehicle over four years. The effort grew to include a broader UW student engagement through a Registered Student Organization (RSO) focused on giving participants hands-on experience with industry components, software, and engineering practices while advancing cleaner transportation. The battery electrical interface project seeks to develop a system connecting a 620 VDC battery to a battery electric vehicle (BEV) truck. This project will integrate and test systems such as a high voltage junction box, DC-DC converters, S-box and ECU. The focus is on creating a safe integration into the E-truck system to ensure proper communication between the different power systems and power distribution for other vehicle functions such as steering, torque, and motor control function.
