ABSTRACT
The concept of a hybrid vehicle seeks to create a vehicle system with little energy efficiency and be able to
replace fuel oil. Batteries are used as energy storage for hybrid-electric vehicles. The role of sensors in
hybrid-electric vehicle instrumentation monitoring is used to avoid malfunctioning of instrumentation. In
this study focused on sensing physical parameters in Battery Management System (BMS). The design of
sensing system consists of temperature sensor, voltage-current sensor, rotation speed sensor and IoT-based
data transmission system. MQTT method is used for data transmission which will be processed by smart
server. Smart Server is designed using Single Board Computer (SBC-Raspberry Pi). Sensor data is sent
over TCP / IP network with packet data format. The server computer will record, analyze and notifications.
System testing performed four stages of sensor calibration, data transmition delay and intelligence
algorithm intelligent system. The test results of the error rate of the three sensors (temperature, current and
RPM) obtained percent of data in the sequence as follows 10%, 13% and 9%. The process of sending real-
time data from the sensor to the server needs an average of about 1.4 – 5 seconds (in the Internet Service
Provider network), while for local network only takes 0.5 – 0.9 seconds. The accuracy of the alarm alert
notification algorithm in the monitoring system is about 80%. The intelligent server system development
orientation is to create an integrated system for performance monitoring and functional failure protection
that results in the safety level of users of hybrid-electric vehicles.
