Detailed technical specifications for solar trailer and how does it work in practice
The company has already developed a prototype solar transport trailer, which has been tested on the road from Kamnik to Monaco – 2,000 km, to the Lake Balaton - 900 km back and forth, and on other routes in Slovenia. New testing this year will be from Slovenia to the Black Sea, Ukraine and back – 3,500 km.
Solar trailer is very resistant to external influences and the static load. It is extremely mobile both in cities and in open spaces. It has four electric actuators, which raise the solar panels towards the sun for greater efficiency during a rest. When driving, the panels can be lifted and the efficiency is 270 W and 10 Ah, or suspended where efficiency is up to 170 W, 6.5 Ah. Lithium batteries for normal electric bicycles have to be charging from 4 to 5 hours and can be used only up to 100 kilometers distance. With the help of BEFREE Solar Bikes we can cycle up to 300 km daily with no charging necessary.
Lithium battery has an average life expectancy of up to five years, and flexible solar panels on BEFREE trailer last up to 20 years. Solar trailer can produce electricity very long time for both the electric bike as well as for small solar power plant.
All the metal parts (aluminium, stainless steel, stainless steel screws) are protected by electrophoresis. Electronics has a certificate of resistance to external influence IP68. Since we have an electric bike converter from 48 V to 5 V, we can plug in and charge all modern electrical devices such as mobile phone, GPS navigation, GPS tracker, LED-laser safety lamps and any other.
Due to the highly rigid clamping of solar trailer on the bike (under the driver's seat) one does not feel torsion; the load on bike is half the load to the trailer. Even at high speed (60 km per hour) downhill a biker does not feel torsional load, the trailer extremely well follows to attached bicycle or scooter. After many researches and many years of experience the flexible solar panels have the most favourable position. From sunrise to sunset they have the best efficiency. This position can be further improved with the aid of actuators, four-way switch and remote control. Solar panels have good efficiency also at riding, as the position enables the continuous heat dissipation. At high external temperatures and poor cooling of panels the power of panels can drop by 35%.
With the rapid, practical dismantling of solar panel parts on the trailer, it can be changed into the normal transport trailer. The wheel rim is made of cast aluminum alloy with a capacity of up to 200 kg and industrial ball bearings. Bike tyres have protection against punctures and are made of high quality materials (Schwalbe) for long-distance and extreme adventures. All more invisible parts are equipped with LED-laser lights and light strips. The consumption of these LED lamps, electronic devices is extremely small, that is 3W.
