models with built-in battery and totally autonomous operation.

Our solution for e-mobility.

Coldtainer AuO models are battery powered, for autonomous operation without the need for vehicle power. Will run for up to 10 hours on a single charge. 
The Coldtainers AuO line are a perfect all-electric option to use on commercial vehicles for the delivery of perishable goods. Refrigerated, frozen, and food-safe heated autonomous units are available.

AuO: Autonomous Electric Operation

Coldtainer AuO models are battery powered, for autonomous operation without the need for vehicle power. Will run for up to 10 hours on a single charge. 

Last mile distribution in urban environments will be increasingly encouraged to use 100% electric commercial vehicles.

Taking note of this market trend, OEMs are offering interesting solutions with sufficient autonomy for daily use at reasonable costs.

There are, however, contraindications in case of the refrigerated conversion of electric vans:

  • the weight of the fiberglass insulation, that increases the vehicle’s tare, by decreasing its autonomy;
  • the use of high power consumption electric roof-mounted refrigeration units, with the need to install large-capacity batteries, with the corresponding weight and cost increases.

The Coldtainer AuO models can be used in standard electric vans without any modification to the vehicle.
The on-board battery of the AuO is recharged from the AC mains during vehicle parking period, thanks to the included battery charger.


Currently the Coldtainer F0140, F0330 and F0720 models are normally available as AuO, with a single battery sufficient to operate autonomously during a daily work cycle.

The AuO versions are equipped with VRLA gel batteries, totally safe, with good resistance to vibrations and a use life of more than 600 charging cycles. The included chargers are of 5-phase charge switching type, including the floting phase. Battery and charger are included within the refrigerator dimensions.

The maximum recharging time of the built-in battery is approximately 8 hours. The battery charger can also be used to power the Coldtainer, while maintaining the internal temperature.
