Nissan x OPUS concept camper uses second-life EV batteries to power ‘off-grid’ adventures

The Nissan x OPUS will debut at the Caravan, Camping and Motorhome Show on February 19-24

Nissan Energy and OPUS Campers have collaborated on a smart camping concept that uses second-life Nissan electric vehicle batteries to deliver up to a week’s worth of remote power for ‘off-grid’ adventures.

The Nissan x OPUS concept integrates the recently unveiled Nissan Energy ROAM, a portable, all-in-one, weatherproof power pack harnessing Nissan’s EV battery technology for convenient, emission-free and silent power on the go.

With a storage capacity of 700 Wh and a power output of 1 kW, the ROAM’s lithium-ion cells are recovered from first-generation Nissan electric vehicles, ensuring a sustainable second-life for the batteries.

Mounted in a special compartment at the front of the OPUS, the Nissan Energy ROAM unit provides a power supply to both the 230 volt circuit and the 12 volt circuit (via recharging of the on-board leisure battery which powers the 12 volt system). This helps support enough energy autonomy for around seven days of camping, with assistance from a solar panel accessory.

The Nissan Energy ROAM is able to extend the OPUS’ energy independence to around seven days, based on the combined capacity of the leisure battery, Nissan Energy ROAM battery and one to two recharges of a 400 watt solar panel accessory (which takes 2-4 hours per recharge). This enables more adventurous campers to go completely off the grid for up to a week.

When a top-up charge is needed, Nissan Energy ROAM is easily removed from the modified front compartment. The unit can then be plugged into any standard 230 volt socket and recharged in around an hour. The efficiency of the concept is that the Nissan x OPUS can remain at its remote camping spot without needing to be towed back to an ‘on-grid’ power source.

Alternatively, if a 230 volt socket is nowhere near the camping location, the Nissan Energy ROAM is equipped with a DC input for a solar panel energy feed. A 400-watt solar panel solution can fully recharge the unit in two to four hours.
