Hyakkado Co., a Japanese venture business especially active in electric vehicle (EV) manufacturing, released for sale on April 19, 2011, an emergency household power kit utilizing its EV battery. The company manufactures and distributes Conversion EVs by replacing the engines and tanks of gas-powered cars with electric motors and batteries. Hyakkado has adapted its technology and developed a unit that utilizes its EV battery as an emergency household power source.

The kit consists of a connector cable for an EV battery and an inverter, which converts direct current (DC) electricity from the battery to 100-volt alternating current (AC), enabling it to power AC home appliances. The sales price of the kit is 115,500 yen (about U.S.$1,392) including tax. Specialized staff from Hyakkado will be in charge of installation at an additional charge, as it involves work involving high-voltage equipment.

The Conversion EVs are equipped with batteries rated at six-kilowatt-hours (kWh). When converted to AC using the inverter, the power available is about 5.4 kWh, a conversion efficiency of 90 percent. This is equivalent to about 13 hours of electricity for an average household when calculated based on the average Japanese power consumption of 283.6 kWh per month, based on 2009 data from the Federation of Electric Power Companies of Japan.
