Wireless Battery Management System (Electric Vehicle/Energy Storage)

 

The Simple Solutions Inclusive Wireless Battery Management System is comprised of three main components, the Master, the Cell/Balance boards, and the user interface.  The Cell/Balance boards collect voltage and temperature information from each battery cell in a battery pack and wirelessly transmit this data back to the Master.  The Master collects all of this data, controls contactors and relays and communicates with other subsystems, while outputting information to the User Interface.  The User Interface is a touchscreen device that displays the information collected by the Master and allows the user to make changes to the system.
