LEAF-to-Home in action
Nissan is asking on its blog:
"What could be better than a cup of hot chocolate as the temperatures drop close to freezing… especially when it’s free? How about a free cup of hot chocolate made without needing to draw power from the grid at peak times?"
Free cup of hot chocolate is swell, but this is not the point Nissan is trying to make..
Nissan is demonstrating its LEAF-to-Home system at the 2014 World Economic Forum in Davos, Switzerland. The system can utilize a 6 kW bi-directional CHAdeMO charger to charge the LEAF or to draw energy from the battery pack to power some electrical device.
"Car-powered hot chocolate is fun, but there’s a serious side to the LEAF-to-home technology. By incorporating a special Power Control System into a household’s electrical distribution board, a LEAF can not only recharge its batteries in the usual way, but can also use the stored energy to provide power for the house."
Powering a whole house would be sweet, especially if Nissan will someday equip the LEAF with a higher capacity battery pack. If Nissan did this, then EV owners would get emergency supply during a power outage or blackout, reduce consumption of mains electricity during peak times and likely see faster charging of the LEAF.
But for today, let's go for the free cup of hot chocolate.
