Abstract
Lithium-ion (Li-ion) battery technology plays a major role in modern power applications. However, intrinsic technology limitations require a battery management system (BMS) to ensure all Li-ion cells’ safety. Moreover, high-power and high-voltage applications utilize several parallel, and series connected cells, forming a large battery pack that results in unavoidable cell mismatches. Therefore, large battery packs employ cell balancing circuits, where the BMS controls their operation. Furthermore, a central power electronics converter interfaces the battery pack to the high-voltage DC rail, reducing the system’s reliability. A battery power module (BPM) has emerged as an individual battery cell connected across a low-power and low-voltage power electronics converter. However, to utilize the BPM as a building block to achieve higher power or higher voltage systems, the individual BPM’s power management strategy plays a major role. The published works rely on output voltage regulation, which degrades connecting BPMs in parallel. However, this dissertation aims to control the input current of the individual BPMs, resulting in a configurable LEGO/Meccano BPM that can be connected in series or parallel with additional BPMs.
