Toyota's Hybrid Synergy Drive is an evolution of the hybrid powertrain that powered the game-changing Toyota Prius. The Synergy Drive replaces a traditional geared transmission with a drive unit that includes an electronic continuously variable transmission. The system allows power to be split between the wheels and an electric generator. (Photo courtesy of Toyota)
The only viable way for an electrical vehicle to become mainstay is micro nuclear power system. I will out live the vehicle and the owner. It will power a vehicle for a lifetime and be passed on. It will be safer then gasoline and other petro fuels. It will run a high horsepower high torque motor that is less then 1/3 the weight if an internal combustion engine. It will work and the engineers know it. It is just as usual a political and corporate world hot potato. If I had the financial means and an off shore self-governing landmass I would build such systems and when all else fails and it will this will be the ONLY viable solution.
WOW, Electric Cars are not for everyone...they only meet the needs of a few more than 85% of the driving public. If you want to commute more than 65 miles daily then I hope your employer is paying you well because you mah pay over $5,000 more each year just for the auto's fuel. I don't...
Is the news so slow that you have some reason for showing us a presentation from August of 2011? We choose not to live two years into the past. We need current information not NOT 28 months old. Lets see current information this has pictures from auto companies who are closed and disolved in bankrupsy. The quote about range of the leaf was wrong also, it is 100 KM not 100 Miles as that is only 68 Miles. "BAD OR OUTDATED DATA IS WORSE THAN NO DATA AT ALL"
I would not be so iritated if you posted this as what we were thinking was fantastic two years ago...
The two motors are NOT connected "Back to Back" they are in line front of one to back of the other, Notice the picture, the two ends being shown do NOT look identical, one is showing the brush holder and the other is showing the internal fan.
The problem with electric vehicles is that the Automotive industry has never really come up with a good market definition. They keep making cars that cost too much, and perform too little. What I mean is - a car that has a 40 mile range is useless for normal uses like commuting. In an ideal world we would all live within walking distance of our job, but most of us have left the family farm so that is no longer a viable option. We choose a house and a job, and often we wind up through circumstances out of our control, looking for a new job. And that new job may not be next door. Do we uproot our family and move to a new house with new schools and churches and friends or do we allow our family to stay in familiar surroundings and commute. And in some areas of the country, there is little choice, the housing close to the jobs is just so expensive that the commute is the only option.
In my opinion, an electric car that can't go 100-150 miles on a charge is, at best, a luxury item and status symbol. It makes no sense to have an expensive electric car that can't get to the store and back without a charge.
Some electic vehicles are very practical - Electric golf carts in retirement communities are an excellent application. They have sufficient range and speed for the typical user. Unfortunaltely the typical user of an automobile has quite different requirements and none of the electric vehicles meet those needs.
Engineers and poltics WOW. Play together. How can you talk about electric's evolution and not go back past 1969, that is yesterday in hstory. Henery Ford's wife drove electrics. That is probably where this article should have started.
My opinion still is there should not be automotive designers working on electrics. Too much baggage. There is way too much weight, coupled with too much size, the charging system is wrong(batteries should be replaced with charged ones instead of charging ones buried in the automobile). An electric car should fit the operator more like a slipper than a boot. Right size the vehicle and the body and suspension could all be carbon fiber as one unit with the use of weight only to provide operator space integraty for safety. Then the drive unit, motor or motor w/engine could be miniscule compared to what drives the Prius, Leaf, or Volt.
One simply has to look at the facts that the funds were raided, to see who is responsible.
There is no use in trying to convince/educate those who have totally bought the KoolAid. Logic does not get through when they shut off the thinking part of their consciousness. Remember:"Teaching the pig to dance is a fruitless endeavor. It is a waste of your time and it irritates the pig."
On a more technical note, the "true" hybrid vehicles do result in an overall reduction of fuel usage, however the "power hybrids" are a joke. They are designed to just boost performance, and have no overall effect on fuel. These are all just an interim measure. We will not see any viable improvement until fuel cell and other more exotic technologies come on line.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
