Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If DC power is allocated dynamically to multiple batteries, then charging efficiency is improved, but control system complexity increases
Solution Approach 1:
The control system continuously monitors battery connection status, charge levels, and power consumption, using this feedback information to dynamically adjust power allocation. The system detects when batteries are connected or disconnected and automatically modifies power distribution to maintain optimal charging efficiency without requiring complex manual control.
Solution Approach 2:
The power allocation system operates autonomously by automatically detecting battery connections and distributing power without user intervention. The control system self-manages the complexity of coordinating multiple batteries, allowing users to simply connect their batteries while the system handles all allocation decisions based on real-time conditions.
2Quantity of substance
If a single module charges multiple batteries simultaneously, then installation costs are reduced, but power distribution management complexity increases
Solution Approach 1:
The invention combines the functions of multiple chargers into a single DC power electronics module that can simultaneously charge multiple batteries. By merging multiple charging functions into one device, the system reduces the total number of chargers needed and simplifies installation while integrating power distribution management within the single module.
Solution Approach 2:
The power distribution management is segmented into independent control channels for each battery connection point. The system can independently manage power allocation to each connected battery through separate detection and control pathways, allowing complex multi-battery management to be broken down into manageable independent segments that operate under unified control.

AI summary
Various disclosed embodiments include illustrative direct current (DC) power electronics modules, charging systems, and methods. In an illustrative embodiment, a DC power electronics module includes an electronics component configured to provide DC power to at least a first battery and a second battery, a processor configured to communicate with the electronics component, and non-transitory computer-readable media configured to store computer-executable instructions. The stored instructions cause the processor to determine connection status of the first battery and the second battery to the DC power electronics module and instruct the electronics component and/or a connection device to allocate DC power to the first battery and the second battery responsive to the determination that the first battery and the second battery are connected to the DC power electronics module.
