[21.02.2019] Nissan wants to use the old batteries of electric cars in the future even better, including in the portable energy storage "Nissan Energy ROAM".

At some point, the capacity of rechargeable battery cells has dropped so much that they are no longer suitable for use in the electric car, for example. This means that the range of the Stromer drops accordingly.

Therefore, depending on the automaker either individual battery packs or even the whole battery unit are replaced as soon as a certain capacity limit is exceeded.

However, the batteries can still be used in other energy storage, for example, in stationary or portable energy storage.

Nissan Energy ROAM portable energy storage delivers electricity anywhere – for up to a week, from lithium-ion batteries sourced from Nissan first-generation electric cars, which are reused here.

The mobile, weatherproof storage solution is now used in the new Nissan x OPUS Concept – the study of an inflatable camping trailer, which was developed in collaboration with OPUS Campers. It is based on the AIR OPUS, which is ideal for off-road camping: An integrated compressor inflates the compact and lightweight camper in about 90 seconds. Inside there is a sitting / dining area, sleeps up to six people and a kitchen with 230 volt microwave, two burner gas cooker and fridge. The residents are also well connected: A 230-volt power outlet for home appliances is also on board as USB ports for charging smartphones, LED lighting in the canopy and a mobile 4G WiFi hotspot for up to ten devices.

The necessary energy is provided by the Nissan Energy ROAM storage, which is stored in a special box on the front of the concept vehicle. With its storage capacity of 700 Wh and a power of one kilowatt (kW), it provides both the 230 volt and the 12 volt circuit of the camper with electricity (by charging the battery of the 12 volt system). Even without a power outlet nearby, users have enough "juice" for about a week, supported by a 400-watt solar device.


Since the Nissan Energy ROAM is portable, the trailer can even stop at the resort when recharging the battery. Charging takes about an hour at the socket, two to four hours over the solar panel.

The energy storage system is an impressive way to embody Nissan Intelligent Mobility's vision: Nissan Energy ROAM shows how the company is transferring its battery technology and expertise in electromobility to new business models.

Francisco Carranza (Managing Director of Nissan Energy) explains:

"Nissan's pioneering role in energy services not only includes transforming the way people drive, but how they live. The Nissan x OPUS Concept is an example of how Nissan Energy ROAM can be integrated into our lives – for example when camping "," Our customers can control their energy needs at home with intelligent storage solutions. Now we give them complete independence to experience off-grid adventures. "

The Nissan Energy ROAM energy storage system will be launched later this year and prices will be announced later. The camping concept trailer with the innovative storage solution will be presented at the "Caravan, Camping and Motorhome Show" in Birmingham (February 19-24, 2019).
