Charger Slave Mode Control for Multi-Server Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging stations are not versatile in dealing with multiple management center servers, requiring separate protocols for each, limiting their ability to interact with external apparatuses.
Innovation Solution
A charger operates in a slave mode, waiting for input signals from external apparatuses via an interface to control battery charging, eliminating the need for specific protocols for each management center server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charging station is designated as a master and actively sends information to the management center server, then the charging function can be controlled, but the charging station requires separate protocols for each management center server, reducing versatility
Solution Approach 1:
The patent inverts the traditional master-slave relationship by making the charger a slave that passively receives commands from external apparatuses instead of being a master that actively sends information. This inversion eliminates the need for the charger to implement multiple protocols for different management center servers, as it simply responds to standardized commands from any external device, thereby improving versatility while maintaining reliable charging control.
2Adaptability or versatility
If multiple protocols are installed in the charging station for different management center servers, then compatibility with various servers is achieved, but the device complexity increases
Solution Approach 1:
The patent implements universality by designing the charger with a standardized interface that can work with any management center server using a common protocol set. The charger's control unit is configured to receive and respond to standardized commands from external apparatuses, allowing a single charger design to serve multiple server types without requiring multiple specialized protocols, thus reducing device complexity while maintaining broad compatibility.
3Adaptability or versatility
If the charger operates as a slave waiting for external signals, then the charger becomes more versatile with external apparatuses, but the charger cannot initiate charging without external commands
Solution Approach 1:
The patent introduces an intermediary component in the form of a standardized communication interface and control unit that translates between the charger's internal operations and external commands. This intermediary layer allows the charger to maintain its simple slave architecture while providing user-friendly operation through a standardized interface that can accept various forms of initiation signals, including automatic triggering from connected vehicles or manual commands from user interfaces.

AI summary
A charger configured to charge a battery, is provided with a controller configured to control charging of the battery and a communication interface interposed between the controller and an accounting system. The controller waits for an input of a signal from the accounting system via the communication interface. The controller starts to control the charging of the battery under the condition that a signal is inputted from the accounting system via the communication interface.
