|Zytek’s prototype diesel-electric plug-in series hybrid.|
Lithium Technology Corporation is providing three lithium-ion battery systems via its wholly-owned German subsidiary GAIA Akkumulatorenwerke GmbH, to UK-based Zytek Systems for use in a diesel-electric plug-in series hybrid prototype of a four-door smart forfour.
The car is Zytek’s entry in the Energy Saving Trust’s Ultra-Low Carbon Car Challenge (ULCCC) project. The hybrid combines a 1.5-liter, 3-cylinder turbocharged diesel engine with two high-efficiency permanent-magnet electric motors.
The li-ion battery packs have an output of 288 V, a capacity of 7.5 Ah (or about 2.2 kWh of energy) and the a capability to deliver 25 kW of power. These batteries can be charged by either the ICE, by regenerative breaking, or the grid, and will have a modest all-electric range.
The first battery has been installed in the vehicle and road tests will commence shortly. The remaining two batteries will be delivered in April 2006.
LTC, together with Zytek and I+ME, have jointly developed an improved version of the Battery Management System (BMS) to include additional safety features and to control the grid- charging of the battery. The BMS will also communicate with the vehicles energy management system for better efficiency and control.
In December 2005, Lithium Technology Corporation (LTC) announced that it will supply two of the vehicles in Challenge X—one of which is a plug-in hybrid—with its GAIA high-power lithium-ion polymer batteries. (Earlier post.)
Zytek worked with smart on the development of an all-electric drive for a smart fortwo, shown last year. (Earlier post.)
