Electromobile KAIPAN VoltAge
Electromobile KAIPAN VoltAge was established as the joint project of KAIPAN, ISOTRA and VSB-TU Ostrava in 2009.
Project is cofinanced by the named subjects and supported from government agency TIP MPO ČR until 2012 under
project number FR TI1/223. During the years 2009 to 2011 three vehicles has been constructed and are in operation
ready stage. These are known as K0, K1 and K2 from which every vehicle has a variously dimensioned drives. At the
same time the low-cost electric drive installation was finished for AIXAM chassis. KAIPAN VoltAge vehicle was
successfully presented during the contractual negotiations GreenCar in Gwangju, Korea.
„K0“ was assembled in late 2009 and in early 2010 it reached one-charge range of 107 km on the polygon in Hyundai Nošovice. The drive is designed for suburban traffic
and maximum speed is 65 km/h. Set of 100 YLiFePO4 batteries with a voltage of 320 V and 40 Ah capacity is giving the vehicle „Action range“ of 300 000 km. The system is
built for charging at 400V/32A and full charge is archieved under 2 hours (you can also charge at up to 120A).
„K1“ was assembled in 2010 and used for homologation purposes, exhibitions and institutional testing. The vehicle was conceived as an adequate to KAIPAN 14. Maximum
speed is 1135 km/h, acceleration 0-100 km/h under 10 seconds and action range of 250 km on one full charge. Set of LiYFePO batteries with a voltage of 320 V and 100 Ah
capacity is built to be charged from 400V/32A and a full charge is archieved in 3,5 hours.
„K2“ is intended from development and testing of hybridization to improve vehicle dynamics and increasing of the action range as well as emergency charging station
reachout. Car has the same specs as the „K1“ model.
The certification for public roads operation of the KAIPAN VoltAge vehicle is currently underway. Electromobile and its
components are commercially offered by KAIPAN company (final chassis kit form), electrical systems (ISOTRA),
electronics (VSB-TU Ostrava) and charging stations (VSB-TU Ostrava together with ZTC Group).
KAIPAN VoltAge roadster is built on standard chassis of KAIPAN 14
with spacial distinctions for integration of electrical drive systems.
Two-seated monocoque body is made from negative form. The body
can be realized in two basic materials, glass fiber or carbon fabric. For
additional security and integrity, bodykit can be produced from
combination of carbon and kevlar fabric. This bodykit weights less
than 25 kg. Assembly is done either by KAIPAN company or customer
can order a supply kit for home-construction.
Drive unit KAIPAN VoltAge is realized by two water-cooled
asynchronous electric motors with incremental feedback sensor
located before the front axle. The vehicle is frontal axle driven and
each wheel has its own electric motor connected through reduction
gearbox. Other functions such as differential, ABS and so on, are
handled electronically. Water cooling circuit is implemented by use of
the electrically powered water pump and the system is cooling both
drive and the power electronics simultaneously. Electric motors and
gear systems are manufactured in range of 3,5 – 24 kW and
produced by ISOTRA.
The electronics of the KAIPAN VoltAge are developed and
tested at workplaces in VSB-TU Ostrava. The converters,
electric motors, charging system, charging cables, sockets
and stands were all developed and tested this way. At the
moment the development and testing of alternatives from
LENZE, SIEMENS, MGM Compro, MeanWell, Menneked,
Lapp and more are underway.
