Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional battery chargers monitor and control both current and voltage for each battery bank, then charging precision and reliability are improved, but system complexity and cost increase
Solution Approach 1:
The patent extracts current monitoring and control functions from each battery bank, retaining only voltage control. This eliminates the need for current sensors and current control circuits in each bank, significantly reducing system complexity while maintaining charging reliability through voltage-based control
Solution Approach 2:
A single voltage control system serves multiple battery banks simultaneously. The controller monitors voltage and adjusts the charging current for all banks through one control circuit, making the system universal and reducing redundancy while maintaining reliable charging across all banks
2Measurement precision
If conventional battery chargers configure separate banks for each battery, then charging control precision is improved, but system cost increases
Solution Approach 1:
The patent merges multiple separate charging banks into a single integrated system with one voltage control circuit that manages all battery banks. This consolidation maintains precise voltage control while eliminating redundant components, directly reducing system cost
3Reliability
If multiple battery banks each include complete monitoring and control systems, then charging reliability is improved, but manufacturing cost increases
Solution Approach 1:
The patent removes current monitoring and control subsystems from each battery bank, retaining only the essential voltage control function. This extraction reduces the bill of materials and assembly requirements, directly lowering manufacturing cost while preserving charging reliability
Solution Approach 2:
A single control system provides universal voltage control for multiple battery banks, eliminating the need to manufacture and assemble multiple identical control subsystems. This reduces manufacturing complexity and cost while maintaining reliable charging across all banks

AI summary
A multiple bank battery charging system for charging two or more battery circuits simultaneously via voltage control only is disclosed. The multiple bank battery charging system does not monitor current of the charging current nor use current to control generation of the charging current. Instead, the multiple bank battery charging system only monitors voltage of the charging current generated by a controller. The multiple bank battery charging system may include a single output for sending the charging current to the multiple battery circuits for charging. As such, the multiple bank battery charging system is configured to charge multiple battery circuits simultaneously via a charging current discharged on a single outlet. The multiple bank battery charging system may also be configured to charge batteries having any battery chemistry.
