Which comes first: the grid or the electric car?

points may be closer than appear

You turn on a switch and the goes on. But when you plug in electric car, what’s to happen?

It’s a question manufacturers, utility companies, and and regional planners are all asking as are an number of consumers. Who gets the when you recharge at work? How do meet the need for all that electricity?

And how do we afford to build out the when the cars aren’t available or sell the cars, the infrastructure to power them yet exist?

Here’s a quick at some of the needs, challenges, and ideas that are coming to make electric cars a

Socio-industrial concerns

At the beginning of the century, more automobiles in the States were powered by than by gasoline. But the need for travel ranges, a more fuel source, and a reliable infrastructure soon led to the dominance of the internal combustion engine. A later, a new set of concerns are driving a away from gasoline and to electricity as an ideal source for power.

The auto industry is working to carbon emissions.

Car owners are with volatile and rising costs.

Nations and industries are about the availability of energy and the impact of oil dependency on global

Power utilities are developing sources of power including solar and geothermal but don’t any way of storing the extra energy generate on a large scale.

the electric car. While carbon neutral even an automobile uses carbon and carbon fuels currently two-thirds of the world’s electricity cars would represent a break with the internal engine.

In the last six months, has become one of the most common when we meet with companies, says Allan IBM’s vice president of and development for the energy and utilities They need to start at the investments they are going to I can tell you, every we have a meeting with a client, they want to about this topic, if it wasn’t on the agenda.

From to wind-powered cars

Beyond the use of gasoline, one aspect of a nationwide or fleet of electric cars actually help spur the use of low-carbon energy sources. many renewable sources of such as solar or wind can be used to augment the traditional of electricity, but only if the sun is shining or the is blowing. Otherwise, electricity is generally derived from natural gas and nuclear power. world’s power plants on coal for 40% of the power they in the U.S. as much as 50% of the power from coal.) Regardless of the the power generated must be used at the time it’s

And most of the current electrical cannot shift smoothly renewable power sources to power sources and back a great deal of waste in generators on and off.

With the of electric cars on a large for the first time the power would also have battery storage capacity to it. If the wind is blowing and the sun is shining, the generated by these alternate sources could for the first be stored in hundreds of thousands of

The fact that those would most likely be owned, on wheels and with varying travel routes periods of parking and recharging for some interesting challenges, to be


One of the early assumptions electric cars is that would recharge the batteries night while their car is in their garage, paying for electricity on their normal utility bill. There’s one problem with that a lot of people don’t or can’t the car in their garage.

For many it might make more to charge cars up in a more location, such as an employer’s or station’s parking lot. But too, raises questions: Who financially charged for that What if you travel outside utility company’s service how do you pay for that electricity you use?

And how do all cars recharge their during the day in what is already a usage period for electricity, if they are geographically concentrated at or transit stations?

Another is the battery. Most hybrid today rely on nickel-metal batteries the same technology in many consumer electronics For next-generation products, lithium-ion are an increasingly popular choice for because they can deliver more power for their and weight they have a energy density, in the parlance of researchers.

Yet even lithium-ion technology compete with the energy of old-fashioned gasoline. So batteries’ density will have to greatly over the next 10 to enable a large-scale electric car

To provide all this electricity for all vehicles, power grids become smart grids of sending and receiving data with energy. Utility having already started this path for peak reduction, carbon management and reasons, are also now completing and participating in standards bodies to for the energy increase, peak and storage mobility that a new fleet of electric cars

IBM is working with a number of automobile manufacturers, academics and to bring about many of capabilities. For example, IBM’s include.

. as well as projects involving smart lean manufacturing and product management for automakers and many Such as research into batteries.

IBM researchers, along with in other companies and organizations, national labs, have plans to develop a commercially lithium-air battery . Such a would use lithium, an energy-dense, flammable metal, to react the readily available oxygen in the

Because they use air that’s into the battery as needed, than store a second inside the cell, lithium-air could ultimately have an density of more than watt-hours per kilogram (Wh/kg). about ten times the energy from the top lithium-ion batteries and would be comparable to the usable density of gasoline (once the low 12.6% fleet average of engines in automotive use is factored Or, to put it another way, IBM is developing the technology that will an electric car to travel 500 miles on a charge.

How do we get there?

It will investment, says Allan but also synchronization of different including parking lot operators, station companies, local universities, hotels, hospitals, I can go down the list where park their cars for hours at a time. Those are the that also need to electric vehicle charging.

To bring about the widespread and service of electric cars, a lot of pieces have to fall place in a way that’s as much as it is coordination. We have a chicken-and-egg Schurr says. If there enough users and enough then the infrastructure doesn’t get

If there isn’t enough then the vehicles aren’t

It’s no small challenge. But companies, automobile designers, materials researchers and urban and planners with IBM’s are all working now to make this shift from internal engines to electric motors a synchronized, plugged-in reality.
