Zytek Introduces Plug-In Hybrid Demonstrator smart for four
5 December 2006
|Zytek’s prototype diesel-electric plug-in series hybrid.|
Zytek, in conjunction with Lithium Technology Corporation (LTC), has launched a demonstration diesel-electric plug-in hybrid version of a smart for four in London.
The lithium-ion battery pack from LTC subsidiary GAIA Akkumulatorenwerke can be charged by either the internal combustion engine (ICE) and by regenerative braking or by household mains (plug-in hybrid). The vehicle has a fuel economy of more than 84 mpg Imp. (3.36 l/100km or about 70 mpg US) and an all-electric range of 20 miles.
The battery pack 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.
Zytek was awarded £1.8 million (US$3.6 million) by the Energy Saving Trust to develop the new HEV. (Earlier post.) The vehicle utilizes a hybrid power train based on a 1.5-liter, 3-cylinder turbocharged diesel engine coupled with two high-efficiency permanent-magnet electric motors. This car is part of the “Ultra Low Carbon Car Challenge” project that is supported by the Energy Saving Trust.
The vehicle has combined technology developed by LTC, Zytek and I+ME for an advanced Battery Management System (BMS). 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 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.—Steve Tremble, Zytek sales and marketing director
