Battery system (energy storage) is widely used in many different applications such as a backup power supply system for critical electrical equipments, protection systems at power stations, power plants,... In addition, with the development trend of wind power, solar power and electric vehicles, the battery energy storage system becomes more and more popular in applications such as integrating renewable energy sources, electric vehicle charging stations,... Battery Energy Management System (BMS) plays an important role in ensuring safety and reliability during battery operation. This paper presents the results of research, design and fabrication of a monitoring and management equipment for batteries. This is a very important technology in ensuring safe and optimal operation of battery systems. The main functions of the monitoring device are layouted and afterthat its design and manufacture of electronic circuits to implement the monitoring and management algorithm of the battery are performed. Equipment test results for a simple test case in a laboratory to verify the operation of the equipment is shown.
