Design and Testing of a Multimode Capable Passive Battery Management System

Abstract

A customized passive battery management system (BMS), which offers a selection of different operating configurations regarding the connection of external sources and loads, has been developed. The device supports balance, charge, de-balance, discharge and permanent storage battery processes. The control unit is run by its own written algorithm (code). Suggestions for potential hardware and software changes that can be made to expand the capabilities of the device are listed. The device is tested in five different operating configurations and the output data (battery-cell voltages and balancing currents) are plotted in characteristic diagrams. The output data is analyzed and the unique capabilities of the device are explained. The detailed PCB design, code, and output measurement data files are included within the paper.

The Dependence of the Burning Process and Ignition Temperature of a Lithium Cell on Its State of Charge

“…However, it has been noted that the use of certain cooling techniques can be dangerous [ 20 ]. A more general approach is the construction of thermal management systems (TMSs) [ 21 , 22 , 23 ] and battery management systems (BMSs) [ 24 , 25 , 26 , 27 ], which cover all issues of energy and heat transmission in the battery [ 23 , 28 ]. A Special Issue of the journal Energies [ 29 ] is devoted to this topic.…”
