4. Centralized BMS In a centralized battery management system architecture, a single control unit oversees the management of each individual cell. This central BMS within the battery pack is intricately linked to all other battery packs, forming a cohesive network. This system presents challenges in maintenance and troubleshooting due to its centralized nature. Moreover, there's an elevated risk factor, as if the central BMS encounters a malfunction, the entire system becomes vulnerable.

5. Distributed BMS A distributed battery management system architecture employs multiple control units that manage the battery cells. All the electronic components are housed on a control board placed on the cells or modules. It eliminates extensive wiring and cable clutter, facilitating easier troubleshooting and maintenance. Despite the higher upfront cost investment, the distributed BMS design provides enhanced reliability, flexibility, and tailored EV battery management systems. Modular BMS A modular battery management system architecture groups identical battery cells, each in charge of a portion of the battery pack, and provides them a control unit. This control unit then contacts the master control unit to carry out the functionalities. This modular BMS structure employs an equilibrium between both the centralized BMS and distributed BMS, offering a balance in system structure, complexity, maintenance, and performance.
