We Found a 300V FAULT in Our Electric Truck!

We strip down our electric drive axle so it can hit the dyno and prove out our dual-motor rear end design. We break down how two 180 kW motors, one per wheel, with a two-stage gearbox deliver massive torque and high-speed efficiency with fewer failure points than a mechanical axle. Away from the shop, Chase’s parents move into their cabin at the WestingHouses, the crew finally gets grid power after months without electricity, and a new hot dog roller becomes the unofficial office morale booster. Meanwhile in Winnipeg, Yael is deep in the belly of our Undisclosed Truck, tracking down a ground fault caused by coolant in a high-voltage connector and proving why real-world testing matters for Heavy-Duty EVs.
