Charge Controller Dual-Charger Logic for Communication Interruptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charge controllers struggle to allow manual charging at power indications other than 0 kW when communication interruptions occur, rendering charging impossible until communication is restored.
Innovation Solution
A charge controller with a controller that manages a first charger for scheduled charging and a second charger for manual charging, issuing stop instructions when power instruction is 0 kW, allowing manual charging at non-zero power values even during communication interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charge controller stops charging when power instruction is 0 kW, then communication reliability is improved, but charging flexibility deteriorates
Solution Approach 1:
The charge controller is segmented into two distinct charging modes: scheduled charging (first charger) and manual charging (second charger). This segmentation allows the system to handle communication interruptions differently for each mode, enabling manual charging to continue at non-zero power values even when communication is disrupted, while scheduled charging properly stops at 0 kW to maintain reliability.
2Adaptability or versatility
If manual charging is allowed at non-zero power values during communication interruptions, then charging flexibility is improved, but energy loss increases
Solution Approach 1:
The charge controller dynamically adjusts charging behavior based on communication status and charging mode. When communication is interrupted during manual charging, the system maintains flexibility by allowing continued charging at the last specified non-zero power value. The controller monitors communication recovery and can adjust power levels accordingly, optimizing the balance between charging flexibility and energy loss prevention.

AI summary
A charge controller includes a controller that controls a first charger, which corresponds to charging based on a charging schedule in which date and time and power instruction value of charging to a vehicle are provided as a pair, and a second charger, which does not correspond to the charging based on the charging schedule. Further the controller obtains the charging schedule from a user of the vehicle, outputs, to the first charger, charging schedule and further outputs, when the last specified power instruction of the charging schedule is 0 kW, a charging stop instruction, and output, to the said second charger, a specified power instruction value at the date and time specified in the charging schedule, and further outputs, when the power instruction value specified in the charging schedule is 0 kw, the charging stop instruction.
