Abstract
The aim of this paper is to design the charger for an electric motorcycle and analyze the behavior of voltage and current value during charging. The AC voltage supply from a residence is converted to DC voltage to charge the energy storage system by controlling the voltage and current values suitable for the charge process in all periods. The designed charger is based on the principle of a buck converter with using constant current and constant voltage technique in order to charge a 12 V, 21 Ah lead-acid battery inside the electric motorcycle. By considering the results, the first state of battery charging is a constant current mode by using the current of 5 A with the initial voltage of 55 V. In the second mode, the battery charging is done by constant voltage of 72 V and the current is reduced until the battery is full. Moreover, the charging time is about 6-8 hours.
Highlights
In recent years, all transportation requires a large number of fuels in both oil and natural gas types, resulting in environmental pollution
The accelerating growth of electric vehicles is widespread due to its no pollution, since electrical energy can be produced from renewable energy, i.e. solar, wind, and so on
There are some disadvantages of using an electric vehicle, which is the limitation of provisional distance
Summary
All transportation requires a large number of fuels in both oil and natural gas types, resulting in environmental pollution. The costs of oil and natural gas are high. For this reason, the accelerating growth of electric vehicles is widespread due to its no pollution, since electrical energy can be produced from renewable energy, i.e. solar, wind, and so on. If the energy storage system is exhausted, it will be charged by electricity. If an electric vehicle needs to take more distance, the large energy storage system will be required leading to an increase in weight. The charge of the large energy storage system necessitates taking long periods
