Mitsubishi’s new power system lets your car power your home
Dendo Drive House automatically shares energy between electric cars and the home
Coming this year, Mitsubishi will sell a system that lets you share power between your home and electric car. Launched today at the Geneva Motor Show, the Dendo Drive House (DDH) features solar panels, a home battery, and a bi-directional charger that lets power flow from your home to your car, or from your car to your home — depending on the economics and which needs the power most. DDH supports cars like the Mitsubishi Engelberg Tourer that the company also announced at the show
There are a number of scenarios when having your car charge your home could be useful. In addition to opening up a world of off-grid living, it could also serve as a backup in the event of a power cut, for example.
The system could also be useful if your electricity tariff offers you a discount during off-peak hours, when the electricity grid is under less load and cheaper to use as a result. For example, your car could inexpensively charge itself overnight, and then power your AC during the day. Of course, this will only work if you’re not planning on using the car to make any trips during that time.
However, while OVO’s system has only been offered on a trial basis to 1,000 households, and Tesla’s plans are currently just theoretical, Mitsubishi says its system will be available to buy later this year.
Don’t expect the system to come cheap however. The bi-directional charger itself could cost as much as €10,000 (although Mitsubishi says it hopes to be able to sell it more cheaply), and you’ll also need to pay for the solar panels, home battery, and mandatory professional installation.
