The hybridization of various energy sources with FC necessitates the utilization of multi-input DC–DC power converter units. These converters also have the same function in distributed renewable energy systems. Based on the respective category, the multi-input converters are summarized in Tables 7, 9, and 10.
Conferences > 2023 7th International Confer... Bidirectional DC-DC converters play an important role in the energy management system of electric vehicles by being responsible for the efficient conversion and transmission of electrical energy between the battery and other electronic devices of the electric vehicle.
In , authors have briefed the energy sources and multi-input DC–DC converter for HEV. Also, the voltage control mode and current control mode of DC–DC converters are addressed. The converter's voltage control mode is a basic control technique due to its simple structural property and ease of implementation.
It is worth mentioning that the dc/dc converter must be bidirectional to ensure the power flow of charge and discharge of the batteries [7, 8]. In this sense, the general structure of a BESS connected to the MV grid is shown in Fig. 1. This system is composed of the battery pack, dc/dc stage and dc/ac stage.
The converter's design will be based on the battery and energy storage system's charging conditions, constant current, and constant voltage operating conditions and the State of Charge (SOC). The non-linearity in the system can be implemented with a sliding mode control.
So, this study evaluates the battery balancing control strategy of the DC-DC converter-based balancing system. From this study, it is concluded that energy storage systems must have control and management facilities for reliable and efficient use even if they have the best battery technology.
