Multi-Chemistry Vehicle Battery Pack With Switchable Cell Groups

The battery system is divided into multiple cell groups, each containing electrochemical storage cells with different cell chemistries optimized for specific functions. Some cell groups use chemistries optimized for energy density while others use chemistries optimized for cycle stability and safety, allowing the system to achieve both high energy density and reliable operation simultaneously.

Different regions of the battery system use different cell chemistries tailored to local requirements. Cell groups located in specific positions or serving specific functions employ chemistries with properties optimized for those particular conditions, enabling the overall system to achieve both high energy density and operational reliability.

The battery system segments power delivery functions across multiple cell groups with different chemistries. Cell groups optimized for power delivery can be activated during high-power demands while cell groups with higher stability are used during normal operation, achieving both high power output and cycle stability.

The system dynamically switches between different cell groups with different chemistries based on real-time power requirements. During acceleration or high-power events, cell groups optimized for power delivery are activated, while during steady-state operation, cell groups with higher cycle stability are used, achieving both high power capability and long cycle life.

The battery system uses multiple cell groups with different chemistries where some cell groups prioritize operational safety and cycle stability while others prioritize energy density. The control system manages the distribution of load across these cell groups to achieve both high safety and high overall energy density.

The battery system effectively creates a composite chemistry architecture by combining multiple different cell chemistries in a coordinated manner. This composite approach allows the system to achieve properties that would be impossible with a single chemistry, including both high operational safety and high energy density.

The battery system is segmented into multiple cell groups with different chemistries, each optimized for specific applications or operating conditions. This segmentation enables the system to adapt to different power requirements, temperature conditions, and discharge rates by selectively activating appropriate cell groups, achieving high versatility despite increased structural complexity.

The multi-chemistry battery system achieves universal adaptability by designing cell groups that can serve multiple functions. The same cell group with a particular chemistry can serve different purposes depending on operational requirements, allowing the system to be universally applicable across various driving conditions and applications.
