What’s Unique about Energy Metrics for EV Terminal Tractors? What are the Key Drivers? by Brad Wham
- 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
- 4. kWh/mile kWh/hour SOC%/hour Emissions Reductions CO2 tons/truck NOx tons/truck Particulate Matter tons/truck Carbon Monoxide tons/truck Efficiency Metrics Gallons of Diesel reduced per hour Maintenance Costs reduced per hour Financial Efficiency Energy Efficiency How are these measured? Infrastructure efficiency Utilization
- 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 Brad Wham Brad.wham@orangeev.com
