'variation on V2G is called V2H or “Vehicle to Home”'

In the age of rolling blackouts, goes the argument, there will be nowhere to charge the cars. That's obviously an exaggeration, and it tells only part of the story. A few weeks ago, Nissan, which makes the Leaf electric car, turned the tables in this debate by starting trials of a system for electric cars to return power to the electricity grid when they are not being used. The idea is that, because electric cars are plugged into the grid already, the power stored in their batteries can quickly be returned to the grid. Temporarily, they can assist in powering essential systems during an emergency when a sudden power outage results in people being stuck in lifts or carrying out essential tasks in darkness. The concept isn't new. It's been tinkered with for years, but leapt off the back burner after the earthquake and tsunami that devastated parts of Japan and wiped out the Fukushima nuclear power plant in 2011. Power supply in Japan was dramatically reduced, and rolling blackouts went on for months. The same year, Nissan unveiled the Leaf-to-home system at the Tokyo Motor Show, and launched it to the public in 2012. It allows owners of its electric vehicles to charge their cars during periods of low demand, when electricity is cheaper, then use the cars to power their homes when there is greater demand on the grid and the cost of electricity is higher. The feasibility of Leaf-to-home has much to do with the frugal approach to electricity in Japanese homes, which use an average of about 12 kilowatt-hours (kWh) of electricity a day. South African suburban homes use at least double that. The Leaf battery holds 24kWh - which will handle the average load-shedding schedule. Aside from offering two days of electricity during an interruption in power supply, Leaf-to-home saves Japanese consumers the equivalent of about R450 a month in electricity costs. Now the technology has gone a step further. A new office tower called Yokohama i-Mark Place, not far from Nissan's headquarters in the city of Yokohama, has dedicated parking areas where Leaf owners can plug their cars in to recharge. But the charging points are also designed to draw power back if an emergency takes out the lifts and essential lighting. "It's no longer just about the vehicle," said Nissan global chief marketing manager Tony Gardina at a briefing in Yokohama this week. "We see ourselves as the leading car manufacturer in terms of a zero-emission ecosystem, not just of a single car." The Leaf-to-building system at i-Mark Place represents a milestone in Nissan's research into battery packs, secondary use of batteries, charging technologies and the emergence of the "smart grid". Hidetoshi Kadota, Nissan's chief vehicle engineer for electric vehicles, made the point that electric vehicles can now be considered part of the electricity infrastructure. "The car used to have value in providing mobility from point A to point B," he said. "But even without moving, during parking, it now has the potential of providing value to society." The Leaf comes at a price - costing the equivalent of larger and more luxurious cars in South Africa. But in the near future it will be part of a vehicle category that can keep giving back even when petrol pumps, which depend on electricity, dry up.
