Energy Recuperation Axle

An energy recovery axle provides energy to the refrigeration system through a special type of axle that generates energy during braking. When the vehicle is moving, the energy recovery axle charges the battery which then powers the refrigeration system.

In the cold chain services sector, trailers can now generate their own electricity from wheel movement and braking. This technology has been used in the United States for more than three years and benefits companies like McDonald's by powering tail lifts and pallet trucks. It is particularly promising for temperature-controlled trailers.

With an integrated generator, these trailers can run refrigeration units while in motion and charge onboard batteries, keeping things fresh for up to 90 minutes when stationary. This innovation reduces dependence on the electricity grid, aligns with sustainability goals and increases flexibility while reducing product cooling costs.

ERA TIP GroupThe results from our 5+ years of testing are very positive. In 2023, we are working with three transport companies that are driving for Albert Heijn – the largest supermarket chain in the Netherlands – for a 12-month join pilot with Thermo King and BPW.

Battery Only

Battery Only

A battery only electric reefer trailer, is where a battery with charging plug provides the energy to the refrigeration system, similar to a private electric vehicle. The recharging occurs while the vehicle is stationary, during loading/unloading or when parked. To enable this a three-phase power connection is utilized, commonly found most workshops, DCs or loading/unloading location.
Solar

Solar

A solar powered electric reefer trailer is a configuration where a reefer is fitted with solar panels o the roof which are then used to generate energy for the built-in batteries which then supply the refrigeration system with power.
