Nissan's Navara EnGuard concept vehicle isn't an electric car, but it does come with a portable battery pack. The rugged, high-tech SUV is meant to be a rescue vehicle, meaning that it can foray into tough terrains to provide charges for dead electronics equipment or mobile devices.
Any responsible adventurer knows the need for things like satellite phones and other electronic safety equipment, but when those devices run out of charge, it can leave people in a dangerous situation. The Nissan Navara EnGuard can bring a charge anywhere, helping people stranded in the wild.
The SUV's portable battery pack automatically charges through the car's diesel engine, meaning that as long as the Navara EnGuard has gas it will be able to provide charges. On top of a battery pack, the SUV comes with a drone for sending still images and video to rescue crews.
