In this study, battery charge control circuit design which is used for storage in electric vehicles or renewable energy system has been realized. The BMS card is designed for a system of four battery cells. The circuit board is designed based on the CAN-Bus communication system and the STM32f103 series microprocessor is used. Circuit design is made of industrial circuit board specifications. Battery Management System (BMS) card design was realized by taking into consideration the methods to reduce the electromagnetic noise. In this study CAN-Bus communication protocol especially selected. Thanks to this protocol, data from many sensors in the vehicle can be controlled using only 2 wires. Although CAN protocol is used mainly in automotive sector, it is used in many systems including microprocessor due to the reasons such as data transmission rate, low error rate and ease of application. The power circuit, control units and CAN Bus communication layer of the designed card have been tested and ready for use.
