Brad Wham, Sales Team Manager at OrangeEV gave this presentation at the Forth Electric-Powered Equipment webinar on May 10, 2022.

1. What’s Unique about Energy
Metrics for EV
Terminal Tractors?
What are the Key Drivers?
Brad Wham – Sales Team Manager
Orange EV

2. Orange EV Overview
• Pure Play EV Company – Terminal Tractor Focus
• Nearly 400 Trucks Deployed across 100+ Fleets
• Uptime Averaging 98-99%
• Lower Total Cost of Ownership – w/o incentives
• Experience Working within Infrastructure Constraints
• Delivering Trucks and Chargers within 90 Days

3. What makes Yard Trucks / Terminal Tractors different?
• No range anxiety
• Don't need power to go 60+ mph
• Regen braking turns frequent Start/Stop into a good thing
• Minimal energy consumption during “idle” time
• Replaces one of the most inefficient, highest downtime, most
polluting but mission-critical diesel vehicles
• “One of the best, if not THE best, vehicles for electrification”
• EV Yard Truck purchases have the potential to cross the 50%
threshold by 2024

6. Best Efficiency Metric for Yard Trucks: kWh/hr
Assuming 180 kWh Battery Pack, keeping battery above 12% SOC
Operation Type
Energy
Consumption
Battery Hours
Low speed, long idle times 4.3 kWh/hr 37 hours
Muni Waste Transfer & Consolidation
Moderate speed and load 5.2 kWh/hr 30 hours
3PL Global Distribution
Moderate speed and load 5.8 kWh/hr 27 hours
National LTL Freight
Fast pace, high use, rough lot 9.0 kWh/hr 18 hours
Global Manufacturing Spotter Services
Top speeds, heavy loads, large rough yard 11.7 kWh/hr 14 hours
National Rail Intermodal
Top speeds, long moves, large yard 12.4 kWh/hr 13 hours
Global Retail Distribution
Most similar to gallons/hr
for diesel yard trucks
Helps with:
• Planning
• Spec’ing
• Savings calculations

7. Top Factors driving kWh/hour:
1. How often you’re moving
2. How far you’re moving
3. How fast you’re moving

8. Top Factors driving kWh/hour:
4. How heavy
5. Site grade
6. Temperature
7. Tire Rolling Resistance

9. What should you do??
DON’T conform your site and duty cycle to the truck.
Conform the truck to your site and duty cycle.
Top 3 actions:
1. Choose an OEM that has demonstrated long-term success in a similar operation
2. Spec the right battery pack size
3. Select the right charger and charging speed – and plan for it by the breakroom
• Be cautious about a desire to “over spec”
Special Considerations:
No site power availability

10. Don’t fear high kWh/hr numbers
High energy consumption sites  Great cost savings
• Common to see savings of 85-90% for the cost of electricity vs. diesel
• Heavier use / harder working sites have some of the fastest paybacks
Savings scales up as hours and diesel consumption scale up!
Plus M&R Savings @$3/hr - $6/hr = ($12,500 - $25,000)

11. Terminal Tractors can be your gateway to electrification
