increasing oil prices due to oil depletion, global warming and the introduction of compulsory standard gas emissions in cities have had a tremendous impact on the development of new trans-potations technologies [1i in hybrid electric vehicles (HEVs). renewable energy is a new option for improving vehicle efficiency and is economical with lower toxic gas emission to achieve the same power and density energy as a combustion engine. FCs with batteries and SCs are combined to provide additional power rapidly during high demand and to overcome the FC start-time [2]. In many Asian countries, scooters and three-wheeled vehicles are notably popular and are a cheaper form of transportation. They are often used in the cities to travel short distances and avoid trap-fic jams. These vehicles have a capacity of 2-5 kW from an internal combustion engine (ICE). Recently, due to consumers” concern for the environment, small HEVs have been introduced with a power system and no longer use an ICE. For example, three-wheeled rick-Shaw drive train with a hybrid configuration, plug-in electric rick-Shaw with solar assistance [3.4] and FC-
battery powered hybrid system for a tramway have been introduced 5J. This study focused on an EMS in which a control strategy is developed to provide tramway load demand or to optimize the system's energy.
Power sharing and hybridization of FC. battery. Sc from literature review [6-8] shows that controls strategies play a vital rollatini proving vehicle performance and efficiency.it coordinates the power sources to secure the electrical flow of the system. In addition, study of various drive train systems such as series. parallel, series/parallel motor and generator system in electric vehicle in [9-11] encourages the development of HEV in maximizes fuel economy. durability and reliability. Power electronics such asdic/dc converter and inverter has become a major study of Here siarch in for improving power conditioning system. LEV system like electric scooter has also become an interesting system studied in [15-171 The EMS system and controlling in-wheel motor is the major concerned of the research. All mentioned liter-nature review is summarized in Table 1 in relation of HEV
technical characteristics with applied renewable energies.
ln Malaysia. LEV vehicles such as motorcycles or
scooter (range70-125 cc) are widely used for personal transportation such as to office, shopping. schools and etc. Unlike in Europe, USA or Japan. Such transportations are used as recreation. It is estimated that half of the vehicle are used to travel 20 km below per day and half of them may travel more than 30 ken per day [18J. People are unreal-sized that with traveling distance less than 20 km per day. vehicle powered by battery can be used without any refueling stop. The electric vehicle can be recharged at home as well.
