Battery monitoring and protection system
Hladík, Jan ; Červinka, Dalibor (referee) ; Knobloch, Jan (advisor)
This work deals with design of battery management system. Requirements for battery management system and its conception is discussed in the first part of the work. System is able to disconnect load or charger from battery using MOS-FET transistors. It measures battery cell's voltages and is capable of passive balancing. Microcontroller is used for data processing and system control. Schematics, printed circuit board layout and control algorithm was designed. Prototype of the battery management system was then manufactured and tested.

Battery Management Systems for LiFePO4 Accumulators
Sejkora, Petr ; Krajsa, Ondřej (referee) ; Kubánek, David (advisor)
This thesis is about BMS systems for the protection, management and supervision of battery-assemblies serial combination of multiple cells. Next part of the thesis is about facilities for an elementary protection of individual cells before overcharging and undervoltage. Draft shall take into consideration the simplicity, low idle power, security function, modifiability for use with other threshold voltages and low cost design. Function is verified by simulating the operation and measuring.

Battery management system for Formula Student
Macko, Maroš ; Bohrn, Marek (referee) ; Šteffan, Pavel (advisor)
This thesis is focused on battery management for Formula Student monopost. Part of the work is the design and implementation of this monitoring system. The system uses a distributed topology, is divided into the main subsystem and subordinate subsystems. The main subsystem and the selection of suitable components are described. Furthermore, subordinate subsystems are designed, and the fundamentals of battery voltage and temperature measurement are explained. Control firmware is implemented and it is able to communicate with the rest of the car. All systems were tested and they comply with the rules of the Formula Student competition.

Battery Arc Welder
Hrdina, Adam ; Patočka, Miroslav (referee) ; Vorel, Pavel (advisor)
This master’s thesis deals with the design and fabrication of DC arc welder supplied from its own rechargeable battery. Battery cells’ type is LiFePO4 which can provide high currents even at relatively low capacity. The BMS circuits are designed within the battery. Major power part of the welder is a step-down converter with synchronously switching low transistors at the position of free-wheel diode. The converter operates at 100 kHz frequency. The current of the battery welder can be regulated in the range from 0 to 120 A.

HIL testing of student formula battery management system
Přikryl, Matouš ; Brablc, Martin (referee) ; Adámek, Roman (advisor)
The thesis covers the topic of hardware-in-loop testing of the battery management system of student formula. The beginning of the thesis contains a literature review on the topic of battery management systems testing with an emphasis on the hardware and software that can be used for this purpose. In the second part of the thesis, the layout of the BMS connection to the test rig and its subsequent testing is described. Custom models of the formula parts and code written specifically for this thesis were used for the testing of the BMS. The final part contains test analysis and validation of the models of the simulated parts.

Wireless Battery Management System for Military Unmanned Vehicles
Pham, N. N. ; Leuchter, J. ; Dong, H. Q.
This paper introduces a Battery Management System (BMS) for Military Unmanned Vehicles, which uses multi-cell battery packs. The designed BMS is composed of slave modules and a master module. Each slave module is in charge of managing the state of one battery, include flowing current, voltage of battery, voltage of each cell, temperature of battery. From these obtained data, each module can predict the State of Charge (SoC) of connected battery. All slave modules are interconnected to the master module via Wireless Communication Protocol such as Wi-Fi, Bluetooth, or ESP-NOW. The master module will save all the received data to a microSD card, and if required, send these data to a workstation. These data are useful to predict the operation range of the vehicle, which is very important for decision the tactic of using. The designed BMS was verified in various applications in University of Defence in Brno.
