Abstract

This project address the development of a device uses to limit the current from car battery if medium and high power electrical parts (MHPEP) is still switched on when driver leave their car. This situation always occurs when car driver or passenger forget to turn off a MHPEP when leaving the car. Long usage of MHPEP during engine off condition can cause car battery depletion or flat, thus lead to engine fail start. This device is developed to overcome the problem and it is capable to limit drawn current from the battery if the MHPEP is still switch on when there is no car driver or passenger in the car. The main components of the developed device are consists of Arduino UNO microcontroller, current sensor, relay and warning buzzer. A bang-bang controller is usd as a control of current limiter. In the end of this project, the developed device is able to limit the battery current when MHPEP is still switched on during engine-off conditions thus prevent battery flat.
