Retrofitted ice resurfacer project

Introduction

The retrofitted ice resurfacer project used two Zamboni 525 ice resurfacers retrofitted with electric powertrains.

The City of Vernon is the third project to complete a full year of data collection, surveys and interviews.

The Commercial Vehicle Pilots program supported this project with the two retrofits and two Level 2 chargers. 

Total funding: $37,665

Key findings

Emissions and cost savings

  • Avoided 7,238 kg of CO2 from operations
  • Averaged 43 g of CO2 per kilometer
  • Saved $2,773 on the cost of fuel 

Operation and performance

  • Averaged 9.8 km daily distance driven
  • 4,877 km driven
  • 23 km was the largest distance driven in a day
  • Averaged 8.8 km daily range
  • Average speed of 6.5 km/h
  • Averaged 1.4 hours daily drive time
  • 0.4 percent of full charge days ending with less than 10 percent state of charge (SoC)

Charging and energy

  • Start of day SoC averaged 96 percent
  • End of day SoC averaged 79 percent
  • Averaged 11.7 hours of daily charge time
  • Averaged 28 kWh of daily charged energy
  • 264 kWh/100 km of energy consumed while driving
  • 274 kWh/100 km of energy consumed while driving and idling
  • Overall energy consumption was 300 kWh/100 km 

What they learned about using ZEVs

They learned that:

  • Fuel cost savings are achievable
  • Although initially hesitant, drivers appreciate the benefits offered by the retrofitted electric ice resurfacers (REIRs)
  • After 2-3 months of experience, most maintenance issues on the REIRs are fixed the same day
  • They can use the REIRs beyond their range with daytime charging
  • Air quality improved inside the ice rinks

Deploying the two REIRs gave them the confidence to buy a new battery-electric ice resurfacer.
