Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In battery systems with multiple control subjects, rival charge/discharge control scenarios occur, leading to inefficiencies in power throughput, as it becomes difficult to maximize the quantity of input/output power per unit time due to limitations in charge/discharge scheduling and access control.
Innovation Solution
A charge/discharge instruction apparatus and method that includes a charge/discharge instruction unit, a control unit, and a communication unit to manage access requests and instructions for battery systems, ensuring safe and efficient charge/discharge operations by determining whether simultaneous control is permitted based on battery characteristics and power availability, thereby optimizing power throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple control subjects control charge/discharge of battery systems, then control flexibility and adaptability are improved, but rival control occurs making it impossible to charge the battery beyond its capacity and reducing power throughput
Solution Approach 1:
The patent introduces a gatekeeper as an intermediary component that mediates between multiple control subjects and the battery system. The gatekeeper receives charge/discharge control instructions from multiple control subjects, determines whether to permit access based on battery state and instruction characteristics, and selectively transmits permitted instructions to the battery system. This intermediary structure enables multiple control subjects to operate flexibly while preventing rival control conflicts and maximizing power throughput by allowing simultaneous charge and discharge operations when appropriate.
2Device complexity
If one single control subject is permitted to make charge/discharge control of the battery system for a divided period, then control simplicity is improved, but power throughput is lowered because the quantity of input/output per unit time cannot be utilized to the utmost
Solution Approach 1:
The patent implements dynamic control permission determination where the gatekeeper's decision to permit access is not fixed but adapts based on real-time battery state (charge/discharge status, capacity, power limits) and characteristics of incoming instructions. The system dynamically adjusts which control subjects can access the battery and under what conditions, enabling the battery to operate at maximum power throughput by allowing simultaneous charge and discharge operations when the battery state permits, rather than using static time-divided control allocation.
3Reliability
If access control is implemented to prevent rival control, then battery safety and capacity limits are protected, but control efficiency and power throughput are reduced due to sequential access requirements
Solution Approach 1:
The patent changes the control parameter from binary permission (permit/deny) to a nuanced evaluation that considers multiple factors including battery charge/discharge state, capacity margins, power limits, and instruction characteristics. The gatekeeper evaluates whether simultaneous charge and discharge operations are feasible based on these parameters, permitting access when the battery has sufficient capacity headroom or when operations can be safely coordinated. This parameter-based approach maintains battery safety while dramatically improving control efficiency and power throughput compared to conservative sequential access control.
