Tiivistelmä
Power management unit is one of the major parts in energy storage sector. Dynamic power management unit is comprised of multiple super capacitor cell connected in series. Desired output voltage mainly depends on performance and energy production ability of the capacitor pack. Adaptive power management unit is responsible to observe and control the capacitor pack in real time. Life cycle length of the capacitor also depends on the performance and working principles of the PMU. Another key issue of the performance is safety of the capacitor pack as well as the whole system. Due to the fast charging and discharging rate of the rechargeable super capacitor is more compatible than other battery technologies to design PMU. Here 48V PMU is designed with 24 super capacitors pack for wide range of power supply. To increase efficiency of the PMU, proper balancing is done by internal balancing technique of MAX11068 interface board.
The main target of thesis is to achieve 48V output voltage and monitor the voltages & state of charge (SoC) of the capacitor pack. Here 24 super capacitors are connected in series to get 48V output voltage. To monitor/regulate the output voltage, MAX11068 battery pack monitoring board is used. PMU monitors the voltages and SoC of the whole capacitor pack and individual capacitor cell .With the help of java programming and MAX1168 board, voltage and SoC of the capacitor pack is observed. A user friendly graphical user interface also used to show all measurement result at real time. From the result window user can easily get the idea of the capacitor performance and how to control the system. This thesis is a versatile smart power management system, some of the idea can use in future thorough research project. Two Arduino microcontrollers helps to better control on grounds problem and MAX11068 board.
