Abstract

This research is the design and development of Skylab tricycles. It is a modified tricycle equipped with a motorbike engine. This type of vehicle is generally used in the northeastern region of Thailand, used for transporting agricultural products from the farm to the market. In addition, it is also used for general contracting in a short distance. This study was to develop a prototype electric vehicle with an electric motor as a power source instead of an engine. An electric motor was used as driving power instead of an engine. The prototype is 1.25 m wide, 3 m long, and 1.94 m high. The front wheel caster angle is 20°. The driving power system consists of two 4kW-48V-DC electric motors, two sets of four 12V-80Ah batteries connected in series (48V) for each motor and one 12V-68Ah battery for powering other electrical equipment. Two electric motors could work alternately or work together depending on load. The transmission system has a 6.5 gear ratio. In performance tests with loads, it could carry up to 500 kg, traveled 40 km on a single charge at a maximum speed of 50 km/h and could start on a 15° slope. The electricity consumption rate is about 1.03 baht per kilometer when fully loaded.
