“…Over last few years, battery-integrated MMCs (BI-MMC) have gained popularity especially for battery energy storage systems (BESS) [12][13][14]. Several pieces of research indicate that there is a great benefit in increasing the controllability of the cells in terms of battery life-time and battery utilization [15,16]. The slightest increase in the battery lifetime and battery utilization typically results in monumental benefits [17].…”

The automotive industry has grown considerably over the last century consequently increasing greenhouse gas emissions and thus contributing towards increase in the average global temperature. It is thus of paramount importance to increase the use of alternative energy sources. Electric vehicles have gained popularity over the last decade. However, a major concern with electric vehicles is their range. The range of an electric vehicle is limited by the battery pack, in particular, the weakest cell of the pack. One method of increasing the available energy from the battery pack is by introducing more electronics. Modular multilevel converters, with their modular concept, could be a viable solution. The concept of battery-integrated modular multilevel converters (BI-MMC) for automotive applications is explored. In particular, the impact of the number of cascaded cells per submodule is investigated, considering battery losses, DC-link capacitor losses, and the converter losses. Furthermore, an optimization of the DC-link capacitors and the selection of MOSFET switching frequency is presented in order to minimize the total losses.
