Owners of the Nissan LEAF will be able to use their vehicles to supply electricity to their homes with a new power supply system developed by Nichicon.
"LEAF to Home" is an industry first backup power supply system that can transmit the electricity stored in the large-capacity batteries of Nissan LEAFs to a residential home. Nissan will showcase this system at its Japanese dealership showrooms beginning in June to help promote efficient electricity management and demonstrate the features built into electric vehicles.
Nichicon will provide the technology to move the electricity from vehicle to home through its EV Power Station units. This power transfer system enables electricity stored in high-capacity lithium-ion batteries onboard a Nissan LEAF to be sent to an ordinary home by connecting the car to the home's electricity distribution panel with a connector linked to the LEAF's quick charging port. The EV Power Station system is similar in size to an external air-conditioning unit, can be installed outdoors. Electricity is stored or supplied automatically in accordance with a household's electricity capacity and consumption.
The EV Power Station can fully charge a LEAF in as little as four hours, which is approximately half the time required when a normal charger is used. All current Nissan LEAF owners in Japan will be able to use the system, depending on their home's installation requirements. With Japanese government subsidies taken into account, the EV Power Station is estimated to cost 330,000 yen with the consumption tax and installation charge (300,000 yen excluding tax).
This system helps to balance the electrical supply system, and can even lower a consumer's electricity bill. The LEAF to Home system will help encourage Nissan LEAF owners to charge their cars with electricity generated during the night, when demand is low, or sourced from solar panels. This assist in balancing energy needs by supplying electricity to the grid during daytime, when demand is highest. It can also be used as back-up power source in case of power outages and/or shortages.
The lithium-ion batteries can store up to 24kWh of electricity, which is sufficient to supply an average Japanese household for about two days. This system underscores an additional attribute of EVs: vehicles which can be used as a storage battery whether they are moving or stationary.
