GIGATRONIC is your development and con-
sulting partner, specialised in electronics and
information technology. In 2012, GIGATRONIK
built an ATV quad with electric single-wheel
drive. This vehicle with a maximum speed of
50 km/h served as a test vehicle and training
object for employees and students. The project
is the result of the further development of the
popular ELMOTO e-bike, for which GIGATRONIK
developed the motor controller in 2009. This
controller, in a new upgraded version, is mount-
ed four times in the e-quad. Belt drives spe-
cifically designed for this project transmit the
5 kW from each BLDC motor independently to
each of the four axles. The modern lithium-ion
battery system guarantees a range of currently
40 kilometres. A central control unit from our
GIGATRONIK Tool Suite coordinates drive and
vehicle management. Traction components and
controllers are connected via CAN and LIN.
Refitting with an electric drive was realised
with almost no weight change. Only minimal
modifications to the frame are required for this
300 kg vehicle to receive road service approval.
Design and development were prototyped using
state-of-the-art automotive industry methods,
processes and development tools. GIGATRONIK
is currently simulating drive dynamic functions
of the e-quad – such as torque vectoring, ASR
and recuperation – using CarMaker
®
from IPG
Automotive GmbH, where they will be virtually
tested and verified.
