One of the less-talked about aspects of electric cars is what we'll do with batteries once they've worn down. Nissan has come up with a clever idea for how they could be used to provide power while camping, and it teamed with trailer manufacturer Opus to show it off.
The solution in question is called the Nissan ROAM, and it's a little cube full of old lithium-ion battery cells from "first-generation Nissan electric vehicles," which we assume includes the original Nissan Leaf, that hooks up to the Air Opus trailer shown above. This bundle of cells can store up to 700Wh of electricity, and can provide power output up to 1kW. It features a variety of outlets for powering small devices and appliances, and supplies power to the onboard lights and heating.
