What are the key design considerations for an EV battery pack architecture?

EV battery pack design must address: Cell-to-module-to-pack configuration (optimizing for energy density, thermal management, and serviceability), Cell chemistry selection (NMC for range, LFP for cost/safety), Thermal management integration (cooling plate design, thermal interface materials, uniform temperature distribution within 5°C), Structural integration (battery as structural member for crash loads), High-voltage safety (isolation monitoring, pyro fuses, manual service disconnects), IP67 sealing, BMS integration, and packaging constraints. Companies like Ola Electric design proprietary packs for specific vehicle architectures.
