Abstract

Konsep mobil listrik bukanlah hal baru. Perkembangan dunia otomotif menyebabkan peningkatan kebutuhan akan bahan bakar minyak. sedangkan energi fosil di dunia ini semakin lama semakin berkurang, karena energi fosil tidak bisa diperbarui. Salah satu metode yang dapat dilakukan untuk menekan pengunaan energi fosil yaitu, dengan cara memanfaatkan energi listrik sebagai sumber energi pada mobil.  Pada penelitian ini dilakukan  rancang bangun purwarupa mobil listrik menggunakan motor motor induksi tiga fasa dengan kapasitas 2200 watt sebagai motor penggeraknya. Kemudian untuk memaksimalkan energi listrik dibuat perancangan sistem mekanik yang bertujuan untuk membuat desain mobil listrik. Untuk mengetahui seberapa besar daya listrik dan torsi yang dihasilkan, maka perlu adanya analisa perhitungan daya dan torsi tanpa beban ketika berkerja secara teoritis. Dari percobaan ini, juga dapat diketahui terdapat adanya hubungan antara torsi dan daya, ketika daya motor naik maka torsi akan akan turun. Hal ini disebabkan, karena kecepatan motor induksi naik sehingga torsi akan turun.

Abstract

In the process of charging the battery, it is necessary to pay attention to the value of the current and voltage flowing to the battery. Currently, the battery is an essential tool for humans. Rechargeable battery technology is also increasingly helping meet human needs. The process of charging a rechargeable battery is carried out by flowing current continuously until the battery voltage increases to a certain value because overcharging can damage the battery so that the battery cannot last long. Charging time and battery life are highly dependent on the nature of the accumulator charger circuit. Incompatible currents and voltages can damage the battery and reduce battery life. This problem can be overcome by using a circuit breaker voltage and current. The charging method used is constant voltage, the cut-off circuit selection using a transistor as a voltage and current breaker has the advantage of being able to cut the voltage and current as limited without the need to replace components. Based on the test results, the cut off circuit can cut off the output voltage and current as limited. Based on the measurement results, the cut off circuit is able to cut off the voltage and current at a voltage of 13.43 V and a current of 0.97 A on a 65 Ah battery.
