Nissan has showcased clever new technology that will allow a Nissan Leaf to power a household on its own for up to two days. The new technology, known as Home Smart Charging, will be available in Japan from as early as summer 2012.
The technology, highlighted on the eve of the Tokyo motor show, is designed to reduce the impact of electric cars on the national grid and reduce the electricity bills of a household by up to 50 per cent. It will also help provide power to a house in the event of a power cut.
The Leaf is connected to a household through a Power Control System (PCS) box. This takes direct current from the Leaf and feeds alternating current into the property. Nissan says the average daily energy consumption in a Japanese home is around 10-12kw, so the Leaf's 24kwh battery would offer up to two days of energy storage.
The car charges at night to ensure it takes advantage of lower energy costs and puts less strain on the grid at peak daylight times. A user can also specify how much charge a home takes from the car to ensure there is enough range in it to complete their next journey.
