Tesla Semi Truck vs Walmart Semi Truck – Video

Tesla Semi Truck vs Walmart Semi Truck – Video

Walmart Semi Truck was revealed on March 26, 2014. Walmart and Peterbilt have collaborated on aerodynamic, hybrid, electrification and alternative fuel projects in the past, each with incremental gains in fuel efficiency and emission reductions. The Walmart Advanced Vehicle Experience tractor combines many of these projects in a single vehicle.

Range extending hybrids are a synergy between electric trucks and series hybrids, and their design reduces the energy storage size required for trucks to run on batteries alone. With Walmart Distribution Centers now located closer to metropolitan areas, transport vehicles have shorter transit times to their delivery destinations. These shorter trips reduce the vehicles’ average trip speed and create more opportunities to recover energy through regenerative braking. The generator and energy storage on the truck are scalable based on the range desired.

The truck features a microturbine Range Extender generator developed by Capstone Turbine Corporation. The company also engineered the truck’s integrated hybrid drivetrain solution. The use of a hybrid powertrain allows the turbine to remain at optimum operating revolutions per minute (RPM), while the electric motor/energy storage handles acceleration and deceleration. A longer-range version of this powertrain would feature a larger turbine and smaller energy storage system.

The Tesla Semi will deliver a far better experience for truck drivers, while increasing safety and significantly reducing the cost of cargo transport.

Without a trailer, the Tesla Semi achieves 0-60 mph in five seconds, compared to 15 seconds in a comparable diesel truck. It does 0-60 mph in 20 seconds with a full 80,000-pound load, a task that takes a diesel truck about a minute. Most notably for truck drivers and other travelers on the road, it climbs 5% grades at a steady 65 mph, whereas a diesel truck maxes out at 45 mph on a 5% grade. The Tesla Semi requires no shifting or clutching for smooth acceleration and deceleration, and its regenerative braking recovers 98% of kinetic energy to the battery, giving it a basically infinite brake life. Overall, the Semi is more responsive, covers more miles than a diesel truck in the same amount of time, and more safely integrates with passenger car traffic.
