Overview:

Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

Massachusetts is testing bidirectional chargers that turn parked EVs into backup energy sources. (yaleclimateconnections.org)

While an electric vehicle is sitting idle in a garage or parking lot, its battery could still be hard at work feeding energy to homes or the power grid.

It really just makes that battery useful in another way – to add some resiliency to your building, add another energy source, and also an economic stream for you.

Rachel Ackerman, of the Massachusetts Clean Energy Center explains that so-called bidirectional chargers allow energy to flow between an EV battery and the grid – in both directions.

The battery can charge when demand for energy is low and rates are cheap, like in the middle of the night. That energy can then be fed back to the grid at times when demand – and rates – are high. That could save homeowners money – and help utilities avoid the need to turn on backup power plants to meet peak demand.

In Massachusetts, Ackerman’s group is leading a pilot project that will install 100 free bidirectional chargers for electric cars, school buses, and trucks. The goal is to identify and resolve any barriers to deploying the technology on a larger scale. So consumers and utilities across the country can make fuller use of EV batteries.

This is what the future looks like- a distributed energy grid.

Notice I didn’t say power grid

Doubt this would be used by anyone unless there is some incentive (money) when your car charges back into the grid. Didn't see anything about that in the article.

This also seems like you are just letting your car battery health deplete faster?

Also i can't post anything about EVs without saying WOW so much money invested in what is still a car.

That's supposed to be the point, you get acceas tosuper cheap solar.say through the day to charge up and they take a percentage of your battery back.through the night and pay you to help balance the load, thats V2G. You also have V2H that allows your car to run your house in case of power outages, V2H

Here.in Australia through the day we often have so much solar being generated that they can't use it all,.so enough ecars with V2G and this solves the issue.

For sure but car batteries are massive and this is only a part cycle, it has minimal impact.

Yes, they really arent part of any solution.

Timely reminder that to take the poly crisis of Climate Change, Pollution, resource depletion etc serisouly we MUST move away from all cars, including Ecars.

Even the IPCC states this and we still keep ignoring them. I see even Norway is starting to move away from ecars.

but also makes clear that simply replacing gasoline with batteries won't be enough: cities must also dramatically curtail the use of automobiles and avoid "locking in" future emissions with more car-dependent infrastructure.

"Only by curbing all motorized transport, particularly private cars, as quickly as possibly can we tackle the climate and air pollution crises"

We're already building GWs of new coal to make ecars
