Brussels, Belgium: Thermo King has launched E-coolpac batteries to power its refrigeration equipment. The E-coolpac range of battery modules and extension packs deliver power from 15kWh to 105kWh and can be fitted or retrofitted to hybrid, LNG, electric or diesel-powered trucks, trailers and marine container chassis, where a genset currently fits.
The E-coolpac project results from a partnership between Thermo King and Aksa Würenlos, a Swiss maker of energy systems that tested and manufactured the batteries. The E-coolpac is a zero direct emission battery power technology allowing customers to electrify refrigerated trucks and trailers and use as a battery genset solution for refrigerated marine containers.
The battery packs are compatible with nose-mount and under-mount truck and trailer refrigeration units including Thermo King self-powered, vehicle-powered and selected Frigoblock solutions. E-coolpac is also compatible with Thermo King marine refrigeration units including CFF and Magnum Plus, as well as other brands of ISO1496-2 reefer units.
“Together with Aksa we combined decades of industry insights and expertise and created highly efficient, reliable and flexible solutions to electrify transport refrigeration,” said Eneko Fernandez truck product leader at Thermo King.
“Our focus was to deliver a product offering robustness and quality tested and validated against strict standards. With E-coolpac, our customers can upgrade their truck, trailer and container fleet to comply with ultra-low and zero emission zones, diesel ban areas, and low noise areas. The modularity of the design also future-proofs customer’s investment, giving them the peace of mind that they can extend their battery range at any time should their needs change.”
The compact dimensions of the E-coolpac include all power electronics, controls, and battery modules inside the same pack, whether it is the 15kWh, 20kWh, 25kWh, or 35kWh model. All units feature the same robust external enclosure and share component modularity. The base unit can be coupled with plug-and-play battery extension modules at any time. Battery extension modules deliver either an additional 35kWh or 70kWh on top of your base of 35kWh, boosting power to 70kWh or a maximum of 105 kWh. Battery extension modules only contain the battery cells and a battery management system as they use the base unit’s controls and power electronics.
“Transporters of refrigerated marine containers running port to distribution center operations or daily reefer container transport, can use E-coolpac as an alternative for diesel gensets to reduce their emissions and comply with local regulations,” said Peter Hansen senior product manager for Thermo King Global Marine, Rail and Bus. “The E-coolpac provides a power source for reefers when they are not connected to grid- or vessel-power and fits on both an EU flexi chassis and an EU skeleton chassis (either side-mount or centrer-mount).”
The E-coolpac uses a telematic system allowing users to view and analyse real time and historical data on vehicle location, operation of the E-coolpac unit, battery state-of-charge and more. Drivers can also monitor and control the unit with an intuitive control panel, enabling the driver to check the battery status, limit the charging current, change the operating frequency between 50Hz and 60Hz, and receive operating alarms.
The battery packs can be charged via standard commercial/light industrial power grids or type 2 / type 3 electric vehicle (EV) charging station.
