| description | A 5kW Lithium-ion based battery energy storage system (BESS) is interfaced with
the microgrid in Laboratory for Clean Energy Research (LaCER) using a
bidirectional converter/inverter system. For the sake of safety and efficiency issues,
the battery energy storage system (BESS) needs to employ a Battery Management
System (BMS). This report presents the design and realization of a Battery Management
System (BMS) in LabVIEW software platform with the help of hardware from NI
Corporation. The designed BMS focuses on the calculation of batteries state of charge
(SoC). The calculation method of SoC is a combination of voltage-based method and
coulomb counting method. Several tests had been conducted to check the accuracy of the
SoC calculation method. The protective and balancing functions are also a main part of
the designed BMS. This project adopted a simplest resistors-based passive balancing
method. Besides built-in protective algorithms, the separated protective part is also
programmed for backup. The whole BMS works well. The balancing method is also
effective. But there are still many improvement works in future. First, the accuracy of the
SoC calculation needs to be improved. Second, a high efficiency balancing method is
also needed. More functions for users of BMS are also needed. |
