Combatra

Our company has assembled a team of technicians, engineers and designers, which together with the experts from the Technical University of Liberec developed the Small Electric Vehicle ELCA and obtained the technology for its low-cost manufacturing.

The company now possesses the necessary know-how and technology for the manufacturing of the Small Electric Vehicle ELCA. Currently, we are raising funds and selling licences, so that an initial small-series manufacturing may start.

If you are interested in getting a licence, entering in a Joint-Venture or any other form of cooperation, please send us an email at info@combatra.cz.

There exists an ecological and cheap solution for individual transportation within large cities!

Combatra has developed a simple and ecological Small Electric Vehicle which only needs a minimum maintenance and has a minimum operational cost.

The basic version is equiped solely with the items necessary for driving and safety. For an easy and cheap production, the body of the vehicle is made from a light, firm and cheap thermoplastic, and a light self-supporting chassis is made from a specially designed aluminium profiles.

ELCA will be produced in three versions – ELCA Hatchback, ELCA Delivery Van and ELCA Solar Semi-trailer. An important advantage of the design is that the chassis and a majority of the body parts can be used for all versions of ELCA

Thanks to the atypical slantwise position of the seats, the length of the vehicle is only 2 500 mm which enables perpendicular parking at the edge of the street as can be seen in the picture bellow. 

The Small Electric Vehicle (hatchback) for 2 persons features a modern body construction with a large storage space in the trunk of 430 liters, which is quite unique for such a small vehicle. Furthermore, the delivery van derived from this version has a cargo compartment as much as 900 liters.

After dismounting the cargo compartment, it is possible to connect to it a unique semi-trailer which is equipped with its own batteries, 2 motors and photovoltaic panels for charging the batteries. It is designed so that a driver may disconnect the semi-trailer and rove with the solo vehicle in the surroundings. A driving range of 140 – 160 km is sufficient because the vehicle is designated for using only in the cities. According to the statistics, a typical city carrier drives about 70 km daily and then he leaves the car in the guarded yard. The workmen, construction companies and small farmers have a similar driving range. For example, the German Post vehicles Streetscooter have a driving range of only 85 km. The operating cost of the small electric vehicles is very low. Average consumption of L6 vehicle is 50Wh/km which results at the price of electricity 0,407 EUR/kWh (eng.kurzy.cz, 2022) in the impressive cost of 2.04 €/100km.

All the electronic equipment (motors, battery, charger, BMS) have been projected and debugged by the experts from the Technical University of Liberec.

The experts from Technical University of Liberec have also developed electrical and electronic devices of the vehicle including display and universal control system applicable in different electric cars.

Combatra was incorporated in 1993 in Prague, the Czech Republic, as a limited liability company. Founded by Ing. Miloslav Kolomazník, the company specialized in constructing and renting of sailing ships. From the year 2013, the company assembled a team of technicians and designers, which together with the experts from the Technical University of Liberec started developing the small city electric car ELCA. After many years of research and development, Combatra now possesses the necessary know-how and technology for the manufacturing of the small electric vehicles. Currently, it is raising funds and selling licences for an initial small-series manufacturing, after which the sale of vehicles will start.
