PHEV System

Environmentally-friendly EV driving for everyday use, motor-based hybrid driving for long-range travel.
A reliable power supply in case of emergencies.

Mitsubishi Motors has been developing electric vehicles (EVs) from early on to tackle environmental problems such as global warming and air pollution. We introduced EVs including the i-MiEV and the Minicab-MiEV, which are mainly used as city commuters. However, it is necessary for EVs to overcome such challenges as driving range and charging infrastructure to meet a broader range of expectations.
Our solution to these challenges is the plug-in hybrid electric vehicle (PHEV). With a PHEV, you can enjoy EV driving for everyday activities such as shopping, and commuting to work, and hybrid driving for outings and longer trips on weekends without worrying about charging. The electricity stored in the drive battery can be used as power supply for outdoor leisure or in case of power outages and other emergencies. You can also use electricity at home via Vehicle-to-Home (V2H) system.
In a sense, PHEV is a storage battery that runs, and it is a social-good mobility that not only provides a solution to environmental problems but also serves as part of infrastructure to supply power even when it is stationary. With environmentally-friendly technologies centered on PHEVs, we will continue to contribute to the realization of a sustainable society.

100V AC power supply (1500W)

After the Great East Japan Earthquake in March 2011, Mitsubishi Motors provided 89 units of i-MiEVs to affected areas for use as shelter contact vehicles and transport vehicles for medical personnel. At the time, the affected areas suffered power outages, and we were asked by those on site if it would be possible to use i-MiEV's drive battery to power electrical appliances. In order to meet this demand, we developed the 1500W MiEV Power Box as an external power supply device and started its sales in 2012, about one year after the Great East Japan Earthquake.
We also equipped this power supply technology as a 100V AC power supply (1500W) on the Outlander PHEV, the world's first plug-in hybrid SUV, which we launched the following year. From the vehicles' on-board outlets, a maximum output of 1500W can by supplied for such occasions as outdoor leisure and emergencies, thereby allowing for the unrestricted use of lights, cooking equipment, and other electrical appliances. This feature does not simply serve as a convenient function to access electricity, but it has also allowed us to propose a completely new way of using automobiles.


V2H (Vehicle-to-Home) refers to the ability of electric vehicles and homes to supply power to each other. Through a V2H device, the drive battery of our PHEV can supply up to 12 days of power to a general household 1 if fully charged and fueled when combined with power generation in the engine.

This capability allows for house lights, air conditioners, cooking equipment, and baths to be used during power outages and disasters, and provides peace of mind as families can stay safe at home as usual. Moreover, this also allows for more economic lifestyles, such as charging the drive battery from a home via V2H device during power contract discounted time periods and then driving the vehicle during non-discounted time periods.

1. Amounts and durations of power supply shown above were calculated by Mitsubishi Motors (assuming average household power usage of approximately 10 kWh/day, not taking conversion efficiency of the V2H device and other factors into consideration). V2H devices are necessary to connect the power of the vehicle with your household. Cannot generate power by starting the engine when connected to a V2H device. Please disconnect from V2H devices when generating power with the engine.
