New Product Enables to Use Power Stored in EV Battery
Mitsubishi Motors Corp developed a power supply unit capable of extracting power from a battery that drives an electric vehicle (EV) and using the power for a device outside the EV.
The unit, "MiEV Power Box," is scheduled to be released April 27, 2012. It can be connected to Mitsubishi Motors' "i-MiEV" and "Minicab-MiEV" EVs. The company expects that the unit will be used for supplying power to a home appliance, etc in a time of emergency or outside the home.
The power supply unit is connected to the rapid charging connector of an EV to extract part of the electricity stored in the battery that is used to drive the EV. The output voltage and maximum output power of the unit are AC100V and 1.5kW, respectively. The unit has one power outlet.
When an EV equipped with a 16.0kWh battery for driving is fully charged, the power supply unit can continuously power an appliance with an output of 1.5kW for five to six hours. It is equivalent to the amount of power that is consumed by a common household in a day, Mitsubishi Motors said.
The power supply unit measures 395 (L) x 334 (W) x 194mm (D), and its mass is 11.5kg. The length of the cable that connects the unit and an EV is 1.7m. The price of the unit is ¥149,800 (approx US$1,818, including tax).
