BMS Application Module Mode Control via External Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery management systems (BMS) lack standardized mode control for application modules, leading to limitations in reusing application modules across different projects and incompatibility with both opened and non-opened AUTOSAR standards, necessitating individual development of software modules.
Innovation Solution
An application module mode control apparatus and method that independently changes modes of BMS application modules by receiving voltage measurements and mode state data, comparing them to predetermined values, and transmitting mode change permission signals to allow flexible mode changes without direct connection to application modules, enabling simultaneous application on both opened and non-opened AUTOSAR layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mode change is directly implemented in respective application modules, then each module can control its own mode, but application modules cannot be reused across different projects with different mode conditions
Solution Approach 1:
The patent introduces a separate mode change control apparatus that acts as an intermediary between the environment and application modules. This control apparatus receives mode change requests, determines the appropriate mode based on predetermined conditions, and controls the application modules accordingly. This mediator enables application modules to be reused across different projects without modifying their internal mode control logic, as the mode determination is externalized to the control apparatus.
Solution Approach 2:
The patent separates the mode control functionality from the application modules themselves. The mode change control apparatus is divided into distinct components: a mode change request receiving unit, a mode determining unit, and a mode control unit. This segmentation allows the application modules to remain simple and reusable while the complex mode determination logic resides in the separate control apparatus.
2Adaptability or versatility
If AUTOSAR Compliant standard software module is developed individually for opened and non-opened AUTOSAR, then compatibility with each standard is achieved, but development time and resources are doubled
Solution Approach 1:
The patent designs the mode change control apparatus with universal functionality that can operate with both opened and non-opened AUTOSAR standards. The control apparatus receives mode change requests regardless of the AUTOSAR configuration and applies the same mode determination logic, allowing a single software module to serve multiple AUTOSAR environments without individual development for each standard.
3Adaptability or versatility
If application modules are replaced to change mode conditions between projects, then mode requirements are met, but system complexity and rework increase
Solution Approach 1:
The patent implements dynamic mode determination where the mode change control apparatus can adapt its behavior based on different project requirements without changing the application modules. The control apparatus contains configurable mode determination logic that can be adjusted for different projects, allowing flexible mode conditions while keeping the application modules static and reusable.

AI summary
The present invention relates to an application module mode control apparatus and a mode control method thereof, and more particularly, to an application module mode control apparatus and a mode control method thereof which can arbitrarily change a mode for each application module regardless of a change of a mode condition of a project by taking charge of changing the mode of the application module so as to independently change modes of one or more application modules that perform functions of a battery management system (BMS).
