As with most industries, technology in vehicles is evolving rapidly, and processes are being refined to make them more efficient. The drive to make cars faster, more economical and safer is there for all to see; the car sector in the UK is reportedly worth ?11 billion, so there is plenty of incentive for the industry to refine their products to make them more attractive to consumers.
So with all that riding on their products it’s no surprise to learn that car technology is rapidly evolving.
Although there are many facets to the evolution of the car industry – from improvements in manufacturing to the streamlining of processes, perhaps the most obvious improvement that consumers can see is in fuel economy. Driven be the need to be ‘green’, the efficiency that fuel cars now have when it comes to igniting fuel, is really quite remarkable.
The main advantage in this change is that fuel is vaporised with a fuel injection, allowing the amount that is being sent into the cylinder to be controlled more closely. That means, in conjunction with intelligent ECU ‘brains’ fitted to modern cars that manage the tiniest amount of fuel, there is less excess fuel that isn’t being ignited, which results in a cleaner, more efficient process. In terms of electric cars, their greatest drawback has always been the length of their charge. Tesla cars have helped battery technology evolve from their early days but their range is till limited. Rather than having to physically connect the car to a power station, charging can occur by proximity. Another aspect of evolution in the electric car industry to do with the batteries themselves is the development of Lithium-Air batteries which, to cut a long story short, can hold a lot more energy due to their density than batteries used today. Interestingly a lithium-air battery has the same energy value-per-kilo as it’s fossil fuel counterpart, meaning a similar sort of range between top-ups. Of course, in this article, we’ve barely scratched the surface when it comes to the evolution of cars over the past couple of decades. Given the speed of change in the automotive industry, changes and advancements will continue to occur. Light duty electric vehicles for the commercial industry have advanced into a reliable and marketable product. Battery electric vehicles, by way of example are especially well-suited for vehicle fleets with predictable travel routes and centralized refueling options.
Companies like UPS, FedEx, Coca-Cola, PepsiCo and Walmart use hybrid electric vehicles in their fleets. In non-road applications, electric vehicles (EVs) and electric-powered equipment fleets are becoming increasingly common. Economic and environmental factors are the top reasons fleets are considering electric-powered alternatives to vehicles that run on conventional fuels such as gasoline and diesel. EVs give performance benefits because their electric motors provide quiet, smooth and more energy-efficient operation than internal combustion engines. Additional energy and fuel savings are available from electric vehicles that incorporate power-conserving technologies like regenerative braking. Because they are powered by electricity, electric vehicles help reduce U.S reliance on foreign oil. Well-to-wheel is an analysis to assess the impact of fuel and powertrain options on energy use and greenhouse gas emissions.
With fewer moving parts, EVs requires less periodic maintenance, are more reliable and incur lower maintenance costs.
While gas-powered vehicles have hundreds of moving parts, the electric motor has one moving part, the shaft, which is very reliable and requires little or no maintenance, says the U.S. Battery electric vehicles: These use batteries to power an electric motor to propel the vehicle. Hybrid electric vehicles: These are powered by both an electric motor and an internal combustion engine, independently or jointly (serial or parallel hybrid). With a parallel hybrid electric vehicle, both the internal combustion engine and the electric motor generate the power that drives the wheels.
Along with giving performance benefits and reducing U.S reliance on foreign oil, electric vehicles requires less periodic maintenance, are more reliable and incur lower maintenance costs. Hybrid electric vehicles may need more maintenance than a typical vehicle since there are two propulsion systems – the regular one and the electric one. The energy conversion unit can be powered by gasoline, diesel, compressed natural gas, hydrogen or other fuels. Plug-in hybrid electric vehicles have a larger battery pack than conventional hybrid electric vehicles. In addition, plug-in hybrids can be configured to operate serially, or in a blended fashion. A plug-in hybrid may also be configured for blended operation, having the battery and the conventional engine operate together. While a vehicle is plugged in and not in use, the utility could take advantage of the extra electrical storage capacity in the vehicle’s batteries to help meet peak electricity demand, provide grid support services or respond to power outages. Vehicle manufactures are also developing ranger extenders for plug-in hybrid electric vehicles.
Fuel cell electric vehicles: A fuel cell combines hydrogen fuel and oxygen to produce electricity used to power an electric motor that moves the vehicle. Researchers, using detailed computer simulation modeling, have shown that hydrogen-powered fuel cell electric vehicles (FCEVs) are superior to BEVs in terms of greenhouse gas reductions, range, refueling time and lifecycle cost. FCEVs are more efficient than gasoline-powered vehicles as hydrogen contains three times more energy per weight than gasoline does. One other drawback is that new facilities and systems will be required for producing, distributing and dispensing hydrogen for FCEVs. The fact is, major technical breakthroughs are needed in rechargeable battery chemistries to make EVs economically viable. Under development is integration supercapacitors and ultracapacitors with batteries to improve electric vehicle performances, battery life and energy economy. Lithium-ion batteries also have a lower self discharge rate than other types of rechargeable batteries.


However, there is another serious challenge to all electric vehicle technologies: accessing the raw materials to make them. These are the core issues being addressed by Technology and Rare Earth Metals (TREM) Center, a division of the Institute for the Analysis of Global Security (IAGS).
The mission of the IAGS TREM Center is to create a forum where policymakers and companies from the minerals, defense technology, cleantech, automotive and finance sectors can advance policies that ensure secure and diverse supply chains for technology metals. The distance that EVs can travel on electric power depends on the size of the battery, the type of vehicle and how it is used.
Some manufacturers are working with roadside assistance providers to have “booster” charging packs to help an EV get home or to a charging station. This Class 2c-3 electric truck – the first in its category – has a range of up to 100 miles per charge, making it ideal for many urban applications, says Mark Aubry, eStar’s vice president, sales and marketing.
The eStar has been purpose-built for electric power, “creating an advantage with a low center of gravity with the battery between the frame rails, not mounted on top, and a 36-foot turning circle,” he says. There is a perception that eclectic vehicles are slow and not very powerful, and that is wrong, says Mike Willmon, president of the National Electric Drag Racing Association (NEDRA).
Electric vehicle racers have set some impressive speed and distance records, achieving this high performance with the basic concept: volts times amps equals power, Willmon explains. To put this in perspective, the 1978 Ford Pinto Willmon races at the drag strip uses a motor controller rated at 348 volts and 2,000 amps. They key to the range numbers many EV racers are getting is lightening the vehicle so energy is not needlessly wasted accelerating mass, and using some form of the new lithium-ion batteries that both reduce weight and increase energy capacity. A technology that will allow widespread adoption of plug-in electric vehicles without negatively impacting the electrical grid is the subject of a commercial license agreement between Battelle and AeroVironment, Inc., of Monrovia, Calif. AeroVironment will use a portion of the licensed technology in a new prototype version of its Level II charging systems. While electric vehicles will ultimately reduce the nation's dependency on oil, some are concerned that millions of electric cars on the road will threaten the stability of the electrical grid. AeroVironment's new prototype EV charging station, incorporating the PNNL technology, will help stabilize the electrical grid by continuously monitoring the grid's alternating current, or AC, frequency and varying the vehicle charging rate in response. An earlier PNNL study found America's existing power grid could meet the needs of about 70 percent of all U.S. Xcel Energy announced the results of a six-month study related to plug-in hybrid electric vehicles (PHEVs) and how an increase in their popularity may affect Colorado. Electric vehicle owners can plug in their cars and forget about them, knowing they'll get the cheapest electricity available and won't crash the grid - using a new technology called the Smart Charger Controller. An undersea cable backed by Google and Asian companies aimed at boosting trans-Pacific broadband was put into service on Thursday, the consortium announced. Dutch telecoms group KPN said Thursday that The Netherlands had become the first country in the world to implement a nationwide long range (LoRa) network for the so-called Internet of Things. A small, squishy vehicle equipped with soft wheels rolls over rough terrain and runs under water. Google is trying to make it easier for you to manage the vast pool of information that it collects about your online activities across phones, computers and other devices.

From carburettors to the fuel injection systems developed from the 1980’s onwards, fuel economy and therefore efficiency has improved and carbon emissions have decreased.
The next step in fuel technology has been hybrid vehicles, which combine electric and fuel technology. One advancement that is addressing this issue is inductive charging which, rather than extending the range of the battery actually deals with the problem of charging.
Electronic driving aids, ECU’s that can send different amounts of power to different wheels, tiptronic gearboxes and intelligent safety measures are just a few of the advancements we’ve seen adopted in commercial vehicles. Just a few years ago it would have seemed impossible that electric cars would be on the road. Electric vehicles are being manufactured in multiple configurations and for diverse applications. Plug-in hybrid and extended range battery electric vehicles provide additional range and flexibility in uses that require longer or more unpredictable routes. The federal government is already investing in electric drive, and will have a fleet or some 11,000 hybrid cars and trucks by the end of the year.
EVs generally have a lower total cost of ownership than internal engine-powered vehicles, even in cases where the initial purchase price is for the time being substantially higher. It would be important to assure that electricity be produced by renewable energies, though well-to-wheel energy use show benefits for EVs even if electricity is made from coal.
A hybrid is designed to capture energy that is normally lost through braking and coasting to recharge the batteries (regenerative braking), which in turn powers the electric motor. Parallel hybrids can use a smaller battery pack and, therefore, rely mainly on regenerative braking to keep it recharged. It uses an electric motor to provide added power to the internal combustion engine when it needs it most, for example, in stop-and-go driving and acceleration. The batteries can be charged by plugging into a standard 110-volt electrical outlet – a capability conventional battery electric vehicles do not usually have, or may be charged by the energy conversion unit when needed.
In a serial configuration, the vehicle runs on electricity alone at some points, like starting, and uses its other power source alone at other times, for example, when accelerating. With these systems, once the battery is exhausted, an internal combustion engine charges the battery after the electric-only range is exceeded. In addition, if hydrogen is not produced by renewable energy sources, the well-to-wheel balance is not good. These batteries do not store electrical energy in the same sense that a fuel tank stores liquid fuel.


New batteries are being developed to extend the range of electric vehicles and lengthen battery life so that the need to replace batteries during the life of the vehicle may be eliminated. These capacitors have a high energy density and can quickly store large amounts of electricity and discharge the electricity on demand to batteries or electric motors which can propel vehicles.
This means that once they are charged, they will retain their charge for a longer time than other types of rechargeable batteries. Minerals like cobalt, which is mostly found in the conflict-torn Democratic Republic of Congo and Cuba. IAGS is a non-profit organization which directs attention to the strong link between energy and security, and provides a stage for public debate on the various avenues to strengthening the world’s energy security.
Like conventional gasoline vehicles, factors such as climate, accessory use and driving style will impact the actual range of the electric vehicle.As the charge on an EV’s batteries diminishes while being driven, the driver will begin to feel sluggishness due to a loss of power and performance. Many EVs will also have charging stations programmed into the GPS to get the driver there quickly.
EPA certification as a clean fuel fleet vehicle, as well as California Air Resources Board (CARB) certification as a zero-emissions vehicle. When it returns to its home base at the end of the day, it can be plugged in and fully recharged within six to eight hours. A chapter of the Electric Auto Association, NEDRA was formed in 1997 to increase public awareness of electric vehicle performance and to encourage, through competition, advances in electric vehicle technology.
In some cases, a racer could convert his lead acid battery-powered EV to lithium and actually decrease weight, increase range and increase power. But by using high-power batteries and motors for racing, the vehicle is no less efficient when running lower power for street driving. The technology may also ultimately result in lower costs for plug-in electric vehicle owners.
Developed at PNNL, the Grid Friendly EV Charger Controller technology tells the car's battery charger when to start and stop charging based upon existing conditions on the electrical grid.
If an unexpected event on the grid causes a rapid drop in the AC frequency, the charging system will stop charging, providing a grid "shock absorber." Under normal conditions, this stabilizing technology will be particularly important as the power grid is expected to rely more and more on variable renewable resources such as wind and solar technologies. However, it fits just fine in nuclear shape of things, allowing to nukes to tend not only for basic, but even for intermediate loads. The evolution of electric vehicle technology is ever going forward, and developments make electric traction technology already suitable for many applications. Battery electric vehicles, such as lift trucks and personnel carriers, are widely used on school campuses, in planned communities, resorts, large business complexes and by government agencies. The controller and charger are electronic devices with no moving parts, and they require little or no maintenance as well.On the other hand, EVs face some significant challenges.
However, when power demands are low, parallel hybrids also utilize the drive motor as a generator for supplemental recharging, much like an alternator in conventional cars.
For example, a PHEV driver might drive to and from work on all-electric power, plug the vehicle into the grid to charge it at night and be ready for another all-electric commute in the morning.
Researchers are working to make the plug-in hybrid concept reversible by developing vehicle-to-grid (V2G) technologies.
The vehicle will continue to operate with no change in performance until the battery can be plugged in and recharged. Hydrogen gas contains only a third of the energy per volume gasoline does, making it difficult to store enough hydrogen to go as far as a gasoline vehicle on a full tank – at least within size, weight and cost constraints. Many people think of the 1937 Hindenburg disaster when they thing about hydrogen.Another challenge is fuel cell durability, reliability and cost. Instead, rechargeable batteries are essentially self-contained electrochemical reactors in which the by-products are retained within the battery housing. Cycle stability is the number of times a battery can be fully charged and discharged before being degraded to 80 percent of its original capacity at full charge.
As with any developing technology, though, the cost should decline as production volume increases. The permanent magnets in electric motors use “rare earth metals” which are mostly produced in China and are under increasing control by Beijing. If the vehicle is a pure electric vehicle, the batteries can be drained completely causing the vehicle to stop, like a car that runs out of gas. The PNNL technology tells a vehicle's battery charger when to start and stop charging based upon existing conditions on the electrical grid.
And our studies have shown that those who use the technology could save $150 or more a year on their electricity bill, and they could potentially receive rebates for providing shock-absorbing services to the grid operator," Kintner-Meyer added. These would allow a two-way connection between the plug-in hybrid electric vehicle and the local utility grid. Fuel cell systems are not yet as durable as internal combustion engines and do not perform as well in extreme environments, such as in sub-freezing temperatures. During recharge, these by-products are reconstituted into their original state where they are ready for another electrochemical reaction cycle.
These types of batteries have a higher energy density and power density than most other types of rechargeable batteries. But long before the vehicle runs out of “juice” there will be notifications, much like the notifications when a vehicle gets low fuel.
EVs, and possibly their second-hand batteries (reused as stationary grid-stabilizers), could possibly increase this share to more than 90%. These systems always contain water, which can freeze at low temperatures and must reach a certain temperature to attain full performance. Maintenance and first diesel cost offset hybrid flex fuel cost with cheap robot assemble vs manual diesel repair. Requiring no specialist engineering knowledge to understand and written in an engaging, accessible style, this is a valuable primer and resource for people in business, policy or study who are keen to understand, encourage and capitalize on the transition to electric mobility.
