High Voltage

Battery pack design, power electronics, and everything that keeps the car's high-voltage systems safe.

The High Voltage subteam designs and builds the car's battery pack and how it interfaces with the rest of the vehicle — speccing current-carrying capacities, finding the right voltage-and-current ratios, and validating that the pack is safe to run. Every PCB in the system, from cell-monitoring boards to pack control electronics, is designed, assembled, and tested in house.

The 2026 Pack

2026 · In Development

Cell: Molicel 21700 P45B
Architecture: 96s4p
Pack Voltage: 400V
Continuous Current: 180A DC

Right now the team's focus is fusible link design and cell stackup — sizing each fusible link so it protects the pack without nuisance-tripping, and figuring out how all 384 cells (96 in series, 4 in parallel) are mechanically arranged and secured.

The 2025 Pack

2025 · Previous Car

Cell: Melasta pouch cell
Architecture: 72s1p
Pack Voltage: 300V
Continuous Current: 250A DC

Motor Controller

Both the 2025 and 2026 cars share the same motor controller: a Cascadia Motion PM100DX. Its nameplate is rated for 100–360 Vdc input and 300A output.
