The first fully autonomous, all-electric engineless refrigerated trailer system has been launched by Carrier Transicold, part of Carrier Global Corporation. Suitable for operation with the engineless versions of Carrier Transicold’s Vector HE 19 and Vector 1550 E, the Vector eCool combines the company’s E-Drive all-electric technology with a new cutting-edge energy recovery and storage system.

The new system converts kinetic energy generated by the trailer into electricity, which is then stored in a battery pack to power the refrigeration unit. This loop creates a fully autonomous system that produces no direct carbon dioxide or particulate emissions.

When operating on battery power, the energy management system of the refrigeration unit automatically switches on when the charge reaches a certain level and conditions, initiating the generator to recharge the battery to ensure full refrigeration capacity. The eCool system can also be plugged into the electrical grid when the trailer is parked and will fully charge in under four hours. On the road, the battery pack is recharged using power generated by the axles and the kinetic energy created under braking.

When used with Carrier Transicold’s flagship Vector HE 19 unit, the Vector eCool is said to provide even further reductions in energy consumption. Even with the system’s axle generator and battery pack fitted, it is still significantly lighter than a standard diesel unit with a full tank of fuel.
