Lithium Technology Corporation (LTC) (OTC: LTHU) and Zytek Systems have sucessfully converted a Daimler Chrysler Smart ForFour into a demonstration plug-in vehicle. The vehicle has a fuel economy of over 84 mpg and an all-electric range of 20 miles which is considerably better than the range of HEVs currently on the market.
The Li-ion battery, developed by LTC subsidiary GAIA Akkumulatorenwerke, has an output of 288 V, a capacity of 7.5 Ah (or about 2.2 kWh of energy) and a capability to deliver 25 kW of power. The battery can be charged by either the internal combustion engine (ICE) and by regenerative braking or by plugging into a electric outlet.
The car uses an advanced Battery Management System (BMS) resulting from a combined technology development effort by LTC, Zytek and I+ME. The system is equipped with additional safety features to control the charging of the battery from the mains. The BMS has been designed to communicate with the vehicles’ energy management system to ensure enhanced efficiency and control.
The vehicle utilizes a hybrid power train based on a 68 hp, 1.5 liter, 3-cylinder turbo charged diesel engine coupled with two high-efficiency permanent-magnet electric motors.
The combination of LTC’s advanced battery system and Zytek’s innovative hybrid drive train, demonstrates a positive step forward in plug in hybrid technology that is simply applied to any OEM platform, as the system is scaleable and transportable,” commented Steve Tremble the Zytek’s sales and marketing director.
This car is part of the “Ultra Low Carbon Car Challenge” project that is supported by the Energy Saving Trust. Zytek was awarded £1.8 million by the Energy Saving Trust to develop the PHEV.
It appears that the diesel engine is connected to the transmission.
But why would they do that? Would it not be more cost effective and simpler to have the diesel run a generator instead?

Yep that's called a serial hybrid. Two motors, one electric to drive it, and one that uses fuel to generate electricity.
A better choice than the complication of those transmission systems.
With a fuel cell/microturbine that runs on biofuel a serial hybrid would get 5 times the mileage of an iCE model, withoit even a plugin battery. With plugin it would average 10 times the mileage or more.

How are they calculating the 84 mpg? All on diesel? If not then what percentage of the miles are on battery?

Hi,
Getting more traffic is important to all of us but don't forget your conversions. I recently started using this service www.traffic2sales.net and I have had really good results, my sales have already increased 5-7%. And even better, I only pay for converted sales so no upfront costs. You should try it, you have nothing to loose. http://www.traffic2sales.net?ref=wcb

Great to have a TRUE electric car available to the public.
How long before I can get one near zip code 38585 ?
Sincerely,

With a lot of options to charge the battery, and with its splendid electric energy management, what more can you ask for? This surely sets the trend for developing and manufacturing hybrid cars that sport less fuel efficiency and better environmental track. Car dealers, for their part, can make the buyers aware of what a hybrid car can bring.
