Nissan has released a 100% electric emergency vehicle concept car called re-leaf. The car is designed to be a mobile power supply after natural disasters or extreme weather. Re-leaf is a working prototype car based on Nissan LEAF passenger car. The passenger car has been substantially modified to operate on gravel covered roads with elevated suspension. The weatherproof plug and socket is mounted directly outside the car and can power 110 to 230 volt devices from the car’s high-capacity lithium-ion battery. The re-leaf can drive to the center of the disaster area, providing fully mobile power to help with the recovery process. The integrated emergency management system can operate medical, communication, lighting, heating and other life support equipment. Nissan points out that when a disaster occurs, it usually takes 24 to 48 hours for power to be restored, depending on the severity of the damage. During this time, it said, electric vehicles could provide zero emission mobile emergency power. < / P > < p > re-leaf was created to demonstrate the potential of electric vehicles in disaster recovery. The car maker made it clear that it was a working concept, but the technology was being used in the real world. In Japan, leaf has been used since 2011 to provide emergency power and transportation after natural disasters. < / P > < p > the electric vehicle can also be used as a mobile energy storage battery to provide electricity for families and society through Nissan energy sharing in non emergency situations. The vehicle can not only pull electricity to charge its large capacity battery, but also push the power back to the grid by using the vehicle’s grid technology. Re-leaf can use its 62 kwh battery to power multiple devices at the same time. According to Nissan, that’s enough to power an average European home for six days. Global Tech
