System Levels Up to now, a precise differentiation and overview between the individual (battery) system architectures has not been made on a scientific basis.
The design variables are mathematically defined as follows: x1 = Share of battery module installation space within the overall battery system installation space in the x-direction. x2 = Share of battery module installation space within the overall battery system installation space in the y-direction.
The battery system components' space allocation was fully parametrized using five interdependent design variables. Four different simulation models were abstracted to depict the battery system's main component groups: cellmodule, cooling, mechanics, and electronics.
The generalized architecture of Proposed BMS design is shown in Fig. 9 (a)- (b). In proposed design, battery management systems (BMS) employ LTC6812 analogue front end (AFE) IC to monitor and regulate battery cell conditions. AFE has cell voltage sensor and external balancing circuitry MOSFET driving connections.
Literature findings are used to validate the overall optimized cost distributions. Generally, very few analyses of total costs or weight shares at the component level for entire battery systems are described in the literature. One bigger compilation is given by Lutsey et al. in .
