+Electric buggy for educational use in vocational schools for automotive students. Possible to use track days in cross country tracks or in winter time when slippery. It is main design purpose is to be a platfrom for studying electric vehicle technology. Buggy type of vehicle is best for that purpose because all the parts and systems are visible through the frame construction. It is made so that there would be minimal risks of electric shock. Low voltage design 60V. To get reasonable power, very high current controller is used. Battery is mounted similiarly as usual road EV-s it is possible to practice EV service with smaller and lighter battery pack then on real electric cars. Battery, weight about 80kg. Nowadays some cars have already 500kg battery pack that can be dangerous to lift by students. Here you have to take into account of the price of real battery if something goes wrong. Also it is not very easy to guarantee safety of the stundents near 400V battery pack. Workshop regulations even do not allow unqualified people near real EV when high voltage systems opened.
