Abstract
The research on the development of electric vehicles includes such as power electronics, energy storage capability that the higher the battery, reducing fuel emissions, and the motor efficiency. The electric motor efficiency requires the automatic control on the main parameters such as speed, position, and acceleration. The performance setting of speed Brushless DC (BLDC) Motor can be improved by using the controller Proportional Integral Derivative (PID), a combination of PID using nature inspired optimization algorithms such as Bat Algorithm (BA). BA is one of the optimization algorithm that mimics the behavior of bats on the move using a vibration or sound pulses emitted a very loud (echolocation) and listen to the echoes that bounce back from the object to determine the circumstances surrounding vicinity 
 In this paper, simulate of Bat Algorithm to find the best value PID controller parameter to speed control BLDC motor and analyze performance such as the value of overshoot, steady state. The result simulation shows that values for the PID parameters without using algorithm bat is Kp = 208.1177, Ki = 1767, and Kd = -8.6025. While using the algorithm bat got value Kp = 5.4303e+04, Ki = -1.3059e+06, and Kd = 3.0193e+04. The performance of the motor obtained through value rise time of 0. 282, settling time of 1.5, overshoot value of 20.5% and the peak value of 1.21.
Highlights
In recent years, research on the development of electric vehicle is increasing, due to the increasing number of motor vehicles in the world consumption of 700 million in a 2.5 billion along with the increasing world
Electric vehicles are classified into three types: pure electric vehicle (PEVs), hybrid electric vehicles (HEVs), and fuel cell electric vehicles (FCEVs)
Battery electric vehicle have the advantage of high efficiency, low noise level, and has the potential to Brushless DC (BLDC) motor circuit equations can be described by the reduce air pollution when charged from a source of renewable energy
Summary
Battery electric vehicle have the advantage of high efficiency, low noise level, and has the potential to BLDC motor circuit equations can be described by the reduce air pollution when charged from a source of renewable energy. The component is the inverter, which is a bi-directional converter, which receives high voltage traction battery and converts it to a three-phase AC voltage suitable for traction. Another component is the controller, is a component that serves to regulate drive torque, the braking energy optimization control, the vehicle energy management, fault diagnosis and processing, and vehicle condition monitoring.
