Mitsubishi Motors (MMC) is following Nissan with a new Dendo Drive House (DDH) package which connects car, building and electricity grid. 

Unveiled at the 2019 Geneva show last month, DDH is an 'eco-system' for home and vehicle to generate, store, and share power, making the car part of the energy infrastructure.

Retail sales start in Japan and Europe this year.

MMC said DDH benefits from real-life EV usage and behaviour intelligence gathered worldwide from 190,000 Outlander PHEV customers and also from several V2X and EV pilot projects. 

Using V2X compatibility, DDH is a packaged system comprising the EV or PHEV vehicle, a bi-directional charger, solar panels, home battery and a Home Energy Management System (HEMS). It is designed for home use but could be expanded to corporate or industrial facilities.

DDH will be offered by dealerships - making it easier for customers to order – bundling together the sale, installation and maintenance of the system components. Some aspects of installation and upkeep may be contracted out, depending on market.

DDH allows customers to charge their vehicle at home using sustainable solar-generated power, and also to supply electricity from their EV/PHEV to their homes. 

Energy costs can be reduced by using solar panels by day to charge the EV/PHEV and domestic storage batteries while night power costs can be reduced by using the bi-directional charger to supply power from the EV/PHEV. 

Solar panels can also power domestic appliances, of course.
