The development of powerful, long-lasting batteries and ready access to a reliable powergrid for recharging remain the critical issues for the success of the battery-electric and plug-in hybrid vehicle of the future, according to the white paper.
This can provide power equivalent to that used at peak day-time periods by a 20-person office space (250m 2 ) over four hours. Recharging can be carried out at night during periods of lower power demand and then used at peak times during the day, thus alleviating pressure on the powergrid at peak consumption times.
If equipment costs were lower, they say, they would install more recharging stations. It could be a virtuous circle: The recharge businesses would do better, EV owners would benefit, and more people would consider buying an EV. The function of the port is to convert AC power from the grid into DC, which is then applied to the battery.
The EV industry is focusing on the personal car market, trying to make the range as large as possible. We found plenty of times during the day when a portion of taxis could slip off to recharge, even if just for a few minutes. The standard now is 200 miles. We suspected you wouldn’t need as much for taxis.
But the cars and SUVs used in these situations drive more miles each year than a typical personal vehicle, contributing a higher proportion of greenhouse gases to the environment. The analysis indicated that electrified fleets had 40-45% lower greenhouse gas costs per trip compared to the gasoline-powered version.
The simplest recharging option is to plug the charging cable supplied with the car into a conventional 230-volt socket. The battery is then charged from the grid at a power level of 2.3 A completely depleted battery is recharged in this way within nine hours. The battery is then 80% recharged after just 30 minutes.
New individualization options help users to recognise that it is “their” vehicle: the Black Panel at the front as well as large projection surfaces at the sides allow the smart vision EQ fortwo to be personalized.

Whenever new technologies are introduced into the powergrid, there’s always a chance they could disrupt the system, possibly even leading to blackouts. Finding ways to deal with the impact on the grid caused by incorporating renewable energy has been the focus of Vijay Vittal ’s research for nearly 20 years.

One of the biggest challenges to the nations powergrid "is going to be the introduction of electric vehicles," said Dana Christiansen, associate director of the Oak Ridge National Laboratory, which has partnered with Nissan, TVA and the state of Tennessee to help develop the charging infrastructure to support the vehicles.
The electricity for recharging has to come from somewhere, which means power plants. Depending upon where you live, power plants are often burning natural resources. The true impact of electric vehicles should consider the make-up of the powergrids where these cars will be used.
A key thing, he said, will be to recharge the batteries at an acceptable time for the electricity grid — to “make sure people aren’t charging at the very peak, peak time,” like late afternoon when the electricity grid is already weighted down by demands like air conditioning. — Mark - Dallas 25.
