The focus of most electric vehicle manufacturers right now is how to improve energy storage in order to extend range. But Mitsubishi is thinking bigger and sees the electric vehicle as an energy provider for your home when necessary.

As The Verge reports, at the Geneva Motor Show this week Mitsubishi unveiled its new Dendo Drive House (DDH) ecosystem comprising of solar panels, a home battery, bi-directional charger, and an electric vehicle. The idea being that energy will be stored in both the home battery and the car's battery, but that energy can be transferred back and forth between the two depending on where it is required.

By creating a bi-directional system, it means an electric vehicle could become very useful if your home experiences a power cut. Driving to get the battery topped up at a local recharge point means you can then drive home and use the energy to keep essential appliances in the home running. Of course, if you use too much energy then both your home and car won't have any power unless the sun is shining for those solar panels.

DDH will be offered by Mitsubishi as a complete system later this year through its dealerships, however, it certainly won't be cheap. The bi-directional charger alone could cost as much as $11,000, then you have to purchase the solar panels, home battery, and pay for installation.

The electric vehicle is an optional part of the system, but one you really need to invest in to take full advantage of the green energy on offer.
