In electric vehicles the energy storage providedby the batteries is of utmost importance: it provides autonomyto the vehicle. However rechargeable batteries cannot operatealone, a Battery Management System is needed to provide safeoperation conditions, monitor its state and balance its charge.In this article a Battery Management System is developed forapplications in electric vehicles and autonomous robotics. Wedesign the system in a modular way to give flexibility and allowportability to different type of battery packs. Low-costmicrocontrollers were used for the system providing alsocommunication with the vechicle´s on-board computer. Apassive balancing schemed is chosen as a way of batterybalancing. The proposed system was tested using a batterypack demonstrating its balancing capabilities.
