The 4ekolka is a 3D printed, electric powered vehicle out of Prague from Petr Chladek. The estimated cost to build this prototype vehicle was $12,000 with half of that for the batteries and battery management system. The vehicle is designed for a top speed of 55 km/h or approximately 34 mph. The 9.6 kWh battery pack consists of LiFePO4 batteries with a capacity of 200Ah @ 48V and the estimated range per charge is 200 km or 124 miles. The 4ekolka is expected to consume about 100 Wh compared to 200-300 Wh for most electric vehicles.
The expected market is for intra-city driving and as a secondary car. The designer is also investigating commercial uses. The vehicle is currently being tested on roads in Prague. Learn more: Electrek.co
