New Battery Technology for Hybrid Vehicles
A battery developer is claiming its technology can extend the range of hybrid electric vehicles. Technology Research Laboratories Inc. (TRL, Research Triangle Park, N.C.) claims its battery technology can extend the range of hybrid electric vehicles to 75 miles or better per charge. The company claims its battery operates on physical chemistry principles different from conventional lead-acid batteries, and is made almost entirely of carbon and plastic materials. Problems with battery technology have hindered large-scale development. Technology advances are needed to improve consumer confidence in hybrid vehicles.
The company said it is initially targeting the “plug-in” hybrid-electric car market which has so far failed to mesh gears due to unreliable and expensive power sources. Battery disposal also remains an issue. TRL claims its testing showed that a four-passenger electric car be powered by less than 1,000 pounds of its batteries and could travel up to 100 miles on a single charge “depending on speed and road conditions.”
A new and entirely different battery energy source developed by TRL provides a means to achieve hybrid electric vehicles with a range of 75 or more miles per charge. These would suffer no degradation in performance as a result of cycling or standing idle, or age.
Total usable energy is 25 kW/hour, TRL said.
Battery life, weight and cost have combined with a lack of battery charging capacity to slow consumer acceptance of electric cars. TRL is claiming a weight power density for its battery technology of up to 80 W per pound with continuous use and up to 200 W per pound at peak use. Volumetric energy density was about 2 kilowatt hours/feet3.
A typical four passenger electric car powered by less than 1000 pounds of TRL batteries would have a range of between 75 and 100 mile depending upon speed and road conditions. Total useable energy of 25+ kwh.
- Life: Indefinitely long in any state of charge
- Behavior: batteries can be totally discharged, left in the charged or discharged state, or rapidly cycled with no damage.
The most suitable vehicle application for these batteries is in hybrid types where the vehicle range is not limited by the battery energy storage. However, for a truly practical ‘hybrid plug-in’ design the batteries should be cheap, long life no maintenance, and have capacity to provide driving distances on a single charge of between 50 and 100 miles. Then, much if not most of our driving would be making use of energy sources other than petroleum, such as nuclear, hydroelectric, solar, etc.

I want to convert a Mazda B2000 to DC power. Are your batteries available now?

Are your batteries economical for a DIY auto converter?

Sir,
We are manufacturers of Windspin- the turbine roof ventilators running by wind horizontally and found producing energy.
We want to know if any technology developed running car using electric, solar and horizontal wind energies.
Kindly give me any information having with you in the above process.
Thanks.

1000 pounds of algae diesel or biobutanol would go a lot farther and the engines that can use it are already on the road today. The electric car is just a dream for the future and a toy for the rich.

I don’t completely agree with justwatching. I think that with plenty of determination and perseverance in research and development, the holy grail of auto efficiency in the future will be a hybrid auto that can run on both algae diesel, biobutanol, etc., as well as also be able to plug into wind, thorium nuclear reactors, and etc.
Not only should a hybrid still have an internal combustion engine, but in the future they should also be designed with cordless recharging using some kind of electromagnetic induction coil where you simply park the car directly over it.

Even better still when it comes to energy efficiency might be a hybrid fuel cell/rechargeable.There has been major advances in methanol fuel cells in recent years. Renewable methanol fuel can be made from just about anything: industrial hemp, algae, recycled trash and garbage.
The battery bank could also be combined with an ultra-capacitor for better performance, and may take stress and workload off the batteries so that they last much longer. There has been considerable advances in this field in recent years also.
The wasteful transmission could be eliminated from future cars also. Just run power directly to a small high - tech neodymium magnet motor attached to the wheels.
Future improvements like this could all make hybrids the super-efficient cars of the future.

Chris S,
Your the one on the right track, except technology has evolved for converting DC to AC power with out the need or use of capacitors. We also have a design for extracting larger amounts of usable electrical power from any PV or thin film solar panels.
