Solution Overview
Problem
Existing charging systems face challenges in appropriately assigning power conversion units to charging apparatuses, leading to inefficiencies in power distribution and charging performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power conversion units are assigned to multiple charging ports simultaneously, then power distribution efficiency is improved, but charging performance of individual apparatuses deteriorates
Solution Approach 1:
The patent implements dynamic assignment of power conversion units to charging ports based on real-time charging status and power requirements. The control device continuously monitors charging progress and adjusts the number of assigned power conversion units, transitioning from static allocation to dynamic reconfiguration that adapts to changing conditions
Solution Approach 2:
The system changes the parameter of power unit assignment by reducing the number of assigned units from apparatuses with minimal power reduction impact. This involves calculating and comparing power reduction across different apparatuses, then selecting those where reduction causes the least degradation in charging performance
2Power
If the number of power conversion units is increased, then charging capacity is improved, but system complexity increases
Solution Approach 1:
The patent makes power conversion units universal by enabling each unit to serve multiple charging ports dynamically. Instead of dedicating specific units to specific ports, any power conversion unit can be assigned to any charging port based on current needs, allowing the system to achieve high charging capacity without proportionally increasing the number of physical units
Solution Approach 2:
The control device acts as an intermediary that manages the complex relationships between multiple power conversion units and charging ports. It handles the assignment logic, power distribution calculations, and coordination, thereby shielding the overall system from the complexity that would otherwise arise from managing multiple power units across multiple ports
3Adaptability or versatility
If power conversion units are reassigned dynamically, then adaptability to new apparatuses is improved, but charging stability of existing apparatuses deteriorates
Solution Approach 1:
The system applies preliminary anti-action by identifying and selecting apparatuses with minimal power reduction impact before reassigning power conversion units. The control device calculates the potential impact of reducing power units on each charging apparatus in advance, then proactively selects those where the impact is minimal, thereby preventing significant disruptions to charging stability
Solution Approach 2:
The patent implements feedback mechanisms where the control device continuously monitors charging status, power consumption, and assignment effectiveness. Based on this feedback, the system adjusts future assignment decisions to maintain stability while adapting to new apparatuses, creating a closed-loop control system that balances adaptability and stability

AI summary
Provided is a charging system that can appropriately assign a power conversion unit to an apparatus to be charged. For this purpose, a unit assignment section is configured to, when a new apparatus to be charged is connected to any of charging ports, reduce the number of assigned units preferentially for one, from among apparatuses to be charged for which the number of assigned units is plural, that involves a smaller reduction in charging power when the number of assigned units is reduced, and to assign the power conversion section in a vacant state resulting from the reduction to the newly connected device to be charged.
