Conversion of a Hotzenblitz to Lithium Polymer from Kokam


kruspan_hotzenblitz_gelb_1 (Source: Kruspan) Grabs, Switzerland - Kruspan Engineering has modified a Full Electric Vehicle "Hotzenblitz" with the newest technology of Lithium Polymer (LiPo) cells from Kokam. This car has now a range (autonomie) of 350km - 400km without need of recharging the cell's.

This is a factor of ~4 in comparison to the former original version with lead (Pb) and at the same time with the advantage of ~100kg less weight! Full speed is around 130km/h (primary dependant upon motor drive system).

The higher battery voltage, less weight and more energy results in much more autonomie, better acceleration, higher full speed and better overall energy consumption, thus much more performance for the client. The car can best be recharged over night (13h charging time for full load) at a normal 230V AC mains plug with 3.3kW and thus best load of the electrical grid.

This is a demonstration of the possibilities of today's battery technology, when they are used in light and efficient cars.

The Electric Vehicle "Hotzenblitz"

Some technical Data with LiPo:
• New Autonomie: ~350km (practically verified in Swiss Mountains with more than 220Ah coming out of the 4 boxes and temperature rise of the Kokam's was never measurable...)
• Nominal Energy of LiPo's: 39.22kWh
• Nominal Voltage: 185V
• Voltage Range: 170V - 209V
• Weight of 4 Accu Boxes: 272kg
• Top Speed: ~120km/h
