Lithium iron phosphate batteries are the future of ice resurfacing.
At WM technics, we placed our bets on the electric drive with lithium iron phosphate batteries for our ice resurfacers. Our machines are born-electric, meaning they were designed from the ground up to glide through ice rinks around the world using electric power. In the dynamic and ever-evolving world of e-mobility, we invest heavily in research and development to stay ahead and bring the most advanced solutions to the market.

01
Lifespan
At least 3-4 times more charge cycles than lead-acid batteries
02
Weight
Up to 75% lighter than lead-acid batteries
03
Efficiency
Significantly better efficiency, leading to lower energy consumption; only 1 to 2 kWh per ice resurfacing
04
Performance
High discharge rates and extremely high peak performance
05
Charging Time
Ultra-fast charging with a quick-charge terminal (80% in 60 minutes)
06
Maintenance
Maintenance-free
07
Energy Density
High energy density – a small battery is sufficient
08
Temperature Range
-45 °C to 85 °C (-49 °F to 185 °F) (recommended: -25 °C to 55 °C / -13 °F to 131 °F)
09
Quick Amortization
Due to less maintenance, high efficiency, and long lifespan
09
Cost/Benefit
High upfront costs but long lifespan
09
Safety
LiFePO4 cells are considered intrinsically safe due to their cell chemistry, meaning thermal runaway and membrane meltdown, which are common in other lithium-ion batteries, are excluded. Additionally, no toxic gases are released during charging, increasing safety for the user.
Lithium iron phosphate Batteries (LiFePO4)
WM technics don’t cope with phase-out products. When we develop new technologies, we only work with state-of-the-art; hence, in terms of battery-powered e-drive in ice resurfacing machines, only with lithium iron phosphate batteries. High cycle stability is only one of the advantages that all lithium technologies have in common: no combustion gases, no unpleasant odors, and no noise.
