<p align="justify"> <br /> <br /> Today, the development of vehicles with alternative energy such as electrical energy as a replacement for fossil fuel energy increasingly rapidly. The development of vehicles with varying electrical energy ranging from cars with electric energy in full, hybrid cars and electric vehicle conversion. One of the electric vehicle conversion under development is a electric vehicle Konversi Angkutan Pedesaan (KAP) developed by the ITB molina team. <br /> <br /> In the electric car conversion is not yet available system to monitor the condition of the battery and electric motor conditions because it is a conversion of a conventional car. Therefore required instrumentation system that can measure the variables on the battery and electric motor is to facilitate the research and development. In this final project will be discussed subsystem to monitor battery, communication module between ECU and storage module in instrumentation system of electric vehicle conversion. <br /> <br /> The monitoring system consists of sensors and microcontrollers used as an Electrinic Control Unit (ECU) to process data obtained from sensors. The data that has been processed by the main ECU can then be transmitted to the other ECU contained in electric car conversions via communication protocol Controller Area Network (CAN). Other ECUs on electric cars that require battery condition data such as Battery Management System (BMS). The data has been obtained stored with the storage module in the form of SD Card memory so that data can be used after completion of data acquisition for subsequent needs such as for research and development purposes. <br /> <br /> The results of this subsystem design is the battery condition data obtained in the form of variable temperature, current and voltage with an accuracy of more than 95%, State of Charge (SoC) of the battery expressed in 0% -100%, the data is successfully transmitted to the other ECU with CAN communication protocol for every 0.5 seconds and data is stored using a micro SD memory storage module with a storage duration of 2.5 years. <p align="justify"> <br />
