Some concern has been raised about the possible health effects of electromagnetic field radiation, known as EMF, for people who drive in hybrid cars. While all electrical devices, from table lamps to copy machines, emit EMF radiation, the fear is that hybrid cars, with their big batteries and powerful electric motors, can subject occupants to unhealthy doses. The problem is that there is no established threshold standard that says what an unhealthy dose might be, and no concrete, scientific proof that the sort of EMF produced by electric motors harms people in the first place.

Taken together, the many studies of EMF radiation and human health have been inconclusive. While studies continue, so does a highly charged argument on Internet forums and elsewhere, between those who see serious risk and those who dismiss such claims out of hand.

Without taking sides, we conducted a study of our own, not to settle the question about human health risk but to measure EMF levels in the hybrid cars in our test fleet.

We took readings from five hybrids and eight conventional vehicles. That gave us readings in milligaus units, the commonly accepted measure for magnetic fields. We measured EMF levels on all 13 vehicles under the same conditions.

Some may raise a specter of doubt, though, since part of the electric and magnetic fields in hybrid cars come from an alternating-current motor rather than the presumably less threatening direct-current used in conventional cars.

To get a sense of scale, though, note that users of personal computers are subject to EMF exposure in the range of 2 to 20 mG, electric blankets 5 to 30 mG, and a hair dryer 10 to 70 mG, according to an Australian government compilation. In this country, several states limit EMF emissions from power lines to mG. However, there are no U.

In this series of tests, we found no evidence that hybrids expose drivers to significantly more EMF than do conventional cars. Consider this myth, busted. Visit our guide to alternative fuels and guide to fuel economy.

General Motors, maker of the Chevrolet Volt plug-in hybrid, and Nissan, maker of the Leaf battery-electric vehicle, each had partnered with a charging station manufacturer and installer.

Car buyers got a garage evaluation and installation quote before they took delivery of their vehicles. They bought the charging stations usually through their car dealers that the automaker recommended. Home charging is the most convenient way to replenish your plug-in vehicle's battery, and now there are many charging stations to choose from.

Home charging stations from electronic equipment giant Leviton are among those available online from various retailers.

This is what the J connector looks like when it is doing its job. This home charging station from Siemens is an example of the type that plugs into a volt wall socket for easy installation.

AeroVironment's portable Turbocord charges plug-in-vehicles from and volt outlets. The company also makes wall-mount stations.

How To Get the Best Home Charger for Your Plug-In Car

Another view of Aerovironment's lightweight, portable Turbocord. A long cord makes it easy to reach your car's charge port, but it can present a trip hazard unless it's kept neatly coiled on the charging station. California-based Clipper Creek is one of more than a dozen home EVSE manufacturers, and was one of the first in the business. GE's entry in the home charging market features sleek design, remote control and can be turned off so it doesn't consume power when not charging. Bosch, one of the top names in electronic equipment, was quick to get into the home EVSE business.

Fast-forward a few years and the marketplace has wrought its magic. Owners and prospective owners of these plug-in vehicles can choose from dozens of home car-charging stations from more than a dozen manufacturers. You can shop direct from the maker online, from various home-improvement retailers or via mass-marketing sites such as Amazon.

Or you can do it old-school and go through your car dealer. A recent survey of plug-in vehicle buyers by Ford Motor Company found that about half still use the dealer-supplied, one-stop service that provides the charging station and installation for one price.

The other half now do their own shopping, both for the home charging station and for competitive bids from local electricians for installation. Having loads of choices can help save money and cut down the time you'll spend charging that new plug-in car. But making the right selection from among the options also requires a little time in order to research the choices and to process and digest all those bids that come from comparison shopping.

The best charger for your home depends on several things. There's the type of plug-in vehicle you have or are planning to get. There are your plans for future plug-in vehicles. Your garage layout comes into play, as do your household electrical service and your charging patterns. Will you want to charge in the daytime, overnight or every time your pull into the driveway?

An electrician qualified to install home car charging stations can help you decide things like the amperage you'll need, the right circuit breakers to install, the best cord length for your situation and where to locate the charging station to minimize installation costs. You can, of course, pay less or more. We'll get into the details later. Installation costs also vary widely. We'll explain that wide range in more detail later, too.

First up, there's some lingo to know. In almost all cases, the charger isn't actually the thing you are going to buy and hang on the wall of your garage or carport. The charger is built into the car. We'll get to the exception to this rule in a minute.Although it doesn't happen often, it is possible for electromagnetic fields EMFs to affect the performance of cardiac implants such as pacemakers.

Fortunately for recipients, though, a new study indicates that EMFs produced by electric cars pose no such danger. The research was conducted by scientists from the Technical University of Munich, working with colleagues from the German Centre for Cardiovascular Research, and from New Zealand's Wellington Hospital.

A total of test subjects were recruited, 83 percent of whom were male, and all of whom were users of cardiac implantable electronic devices CIEDs — in other words, they had all previously been surgically fitted with either a pacemaker or a defibrillator, made by a variety of manufacturers.

Those vehicles differed from one another in their motor power, torque, battery capacity and charging systems. The driving took place on a stationary roller bench rig, on which the resistance was cranked up to maximize the vehicles' motor output. This was done in order to ensure that the EMFs produced by those motors were at least as strong as those generated under real-world driving conditions.

EMF levels both in and around the cars were monitored throughout the tests, as was the performance of the volunteers' CIEDs. While it was noted that the strongest fields were actually generated as the vehicles' batteries were being charged, none of the EMFs were found to be high enough to affect the participants' implants. According to the scientists, this was likely due to the shielding that's built into electric cars, in order to protect their computer systems from electromagnetic interference.

Matthew O'Connor. The research is described in a paper that was recently published in the journal Technology and Health Care.

Nissan Leaf

Digital Cameras.Quick links. My Nissan Leaf. Is it OK to sit in your car while it's on a quick charger? Thu Aug 28, pm The manual says something about not sitting in your car while it's charging if you have a pacemaker. I'm wondering what the EM exposure level is while these cars are charging. Is it safe? I like to eat my lunch in the car while I'm picking up a free, quick charge, but don't want to end up glowing in the dark or something.

Certainly not worth worrying about. I think it was just Nissan's over zealous lawyers at work ElectricMonkey wrote: The manual says something about not sitting in your car while it's charging if you have a pacemaker. It only has Slightly Annoyed mode.

Tesla Referral Code. Re: Is it OK to sit in your car while it's on a quick charge Mon Sep 01, pm I would think that Level 2 charging would have more EMF, due to the alternating current being rectified. CHAdeMo is direct-current provided by the charging stand.

Steady DC creates a magnetic field, but doesn't induce current in other conductors. The danger with a pacemaker is having even tiny amounts of current induced in the leads from fluctuating magnetic fields.

It got a battery capacity upgrade forboosting its rated range from 84 to miles. That aside, the Leaf has pretty much stayed the same for seven years.

At first, we'd expected it to be a model—in parallel with the second-generation Chevrolet Volt introduced that year—but a new Leaf didn't appear in This information is gathered from industry sources, Nissan executives, off-the-record chats with people who work with Nissan, and media reports from around the world.

In form, today's Leaf is an upright five-door hatchback that's either a large compact or a small mid-size car, depending on how you measure. But the details—the rounded ends, the very long lights topped with little fins that stretched to the base of the windshield, and a Space Age-y interior—added up to a car that some loved but others clearly disliked. Discussions since then have indicated that the next Leaf may be somewhat more conventional in appearance.

One possible indicator of styling direction is the Nissan Sway concept unveiled in March at the Geneva Motor Show, which the company said pointed toward its future small-car design language. While widely presumed to be a lightly disguised version of the next Micra minicar, the five-door hatchback concept is a bit larger than that.

We suspect it has elements that will show up in the Nissan Leaf, or at least point in that direction. Nissan design chief and senior vice president Shiro Nakamura said in the fall of that to expand the next Leaf's appeal into a larger market—beyond early adopters—would require to be be a nice-looking car. Oct Then, he said, designers could add more 'spice' in the design for those buyers who might want it—rather than starting with specific design traits that label the vehicle an electric car.

The next Leaf won't necessarily be more conservative, Nakamura argued during an interview at the Paris Motor Show, but simply a very stable, nicely-proportioned car. And for buyers who want to emphasize the Leaf's electric-car nature, there will be trim, lamps, or gauges that do that if desired. Perhaps the single most important facet of the Leaf will be its rated range, or the different ranges offered if there are multiple battery-size options. Three years ago, Andy Palmer—who then headed Nissan product development—suggested that the next Leaf would have a range of perhaps miles, possibly as high as miles.

We expect the base model of the next Leaf to offer a range of about miles, a slight increase on the miles of the updated first-generation Leaf.Global sales totaled overLeafs by December The European market was led by Norway with 33, new units registered by the end of October The Tesla Model 3 is close behind withsales through December Nissan sought to make the Leaf appealing to mainstream drivers by giving it a familiar five-door hatchback design.

It's guaranteed for eight years ormiles. There is no active cooling of the battery pack, only passive cooling by radiation. There is a battery refurbishment program in Japan, but not in the US. According to a report by Warranty Directof 35, Leafs sold in Europe, three had had a battery failure, compared to a failure rate 25 times higher for internal combustion engined cars. The Leaf is generally cheaper to operate than gasoline and hybrid cars.

The body features bulging headlamp enclosures which direct wind away from the side mirrors, reducing drag and noise. Some trims initially came equipped with the telematics system CarWings. From to this used the 2G cellular network.

As of it offers GPS data for routing, and for locating charging stations. It may also provide two-way communication with the car which enables remote control of the climate system, and monitoring of charging status, [20].

Nissan electric vehicles has existed since and the Leaf was preceded by the Altraand the Hypermini. Other companies make compatible charging stations, and companies and local government have various initiatives to create electric vehicle networks of public charging stations.

By March Nissan had plants at Smyrna, TennesseeOppama, Japan, and SunderlandEngland, [24] with production of50, and 50, respectively. The Leaf has extended range due to a more efficient heating system, better regenerative brakingweight reduction, and improved aerodynamics.

The model year Leaf has a dashboard display of the battery's charge percentage. In November Nissan demonstrated on public roads a Leaf based driverless car [28].

There are three trim levels.Recent studies of the EMF emitted by these automobiles have claimed either that they pose a cancer risk for the vehicles' occupants or that they are safe. Unfortunately, much of the research conducted on this issue has been industry-funded by companies with vested interests on one side of the issue or the other which makes it difficult to know which studies are trustworthy.

Meanwhile, numerous peer-reviewed laboratory studies conducted over several decades have found biologic effects from limited exposures to ELF EMF.

Thus, even if EMF measurements comply with the ICNIRP guidelines, occupants of hybrid and electric cars may still be at increased risk for cancer and other health problems. This especially applies to hybrid and electric automobiles as drivers and passengers spend considerable amounts of time in these vehicles, and health risks increase with the duration of exposure.

In January,SINTEF, the largest independent research organization in Scandinavia, proposed manufacturing design guidelines that could reduce the magnetic fields in electric vehicles see below. All automobile manufacturers should follow these guidelines to ensure their customers' safety. The public should demand that governments adequately fund high-quality research on the health effects of electromagnetic radiation that is independent of industry to eliminate any potential conflicts of interest.

Driving and charging of electric cars is likely safe for patients with CIEDs. There have been many studies evaluating magnetic field values in these vehicles. However, there has been no report on the temporal variation of the magnetic field in the cabin.

This is the first study on the long-term monitoring of actual MFs in EVs. In the study, we measured the magnetic flux density B in three shared vehicles over a period of two years. The measurements were performed at the front and rear seats during acceleration and constant-speed driving modes. We found that the B amplitudes and the spectral components could be modified by replacing the components and the hubs, while regular checks or maintenance did not influence the B values in the vehicle.

These results should be considered in updates of the measurement standards. Effect of static magnetic field of electric vehicles on driving performance and on neuro-psychological cognitive functions. Abstract Human neuropsychological reactions and brain activities when driving electric vehicles EVs are considered as an issue for traffic and public safety purposes; this paper examined the effect of the static magnetic field SMF derived from EVs.

A lane change task was adopted to evaluate the driving performance; and the driving reaction time test and the reaction time test were adopted to evaluate the variation of the neuro-psychological cognitive functions. Electroencephalographs EEGs of the subjects were adopted and recorded during the experiment as an indicator of the brain activity for the variations of the driving performance and of the cognitive functions.

Results of this study have indicated that the impact of the given SMF on both the human driving performance and the cognitive functions are not considerable; and that there is a correlation between beta sub-band of the EEGs and the human reaction time in the analysis. Transportation Research Procedia. Abstract Modern vehicles contain various security systems including vehicular networking where vehicles receive relevant traffic information using wireless communications from their peers.

This wireless communication is mediated by the radiofrequency electromagnetic field. Exposure to electromagnetic fields caused by the transportation system is a cause of concern for many people.

Plenty of dosimetric analysis of electromagnetic field carried out by various research groups found out the highest exposure values in the transport. How long-term effects of these fields affect the human organism and what is the mechanism of action, are questions without known answers.

Several studies point to the possible association of different diseases with electromagnetic field exposure.
