Wireless Charging Communication Split for Delay and Demodulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless charging technologies face challenges with communication quality due to complex working scenarios, leading to reduced demodulation success rates, particularly in emergency data transmission.
Innovation Solution
Implementing a dual communication method where in-band communication is used for emergency data transmission with higher delay requirements and out-of-band communication for non-emergency data transmission, utilizing Bluetooth, NFC, or ZigBee, to improve communication quality and processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If in-band communication is used for all data transmission, then transmission delay requirement is met for emergency data, but communication quality deteriorates and demodulation success rate decreases
Solution Approach 1:
The patent segments communication scenarios into two distinct categories: emergency data transmission and non-emergency data transmission. By dividing the communication function into separate pathways (in-band for emergency, out-of-band for non-emergency), the system optimizes for both low delay and high reliability in their respective contexts without compromise.
2Reliability
If out-of-band communication is used for all data transmission, then communication quality improves, but transmission delay increases for emergency data
Solution Approach 1:
The patent applies local quality by assigning different communication channels with different characteristics to different data types. Emergency data uses in-band communication optimized for speed, while non-emergency data uses out-of-band communication optimized for quality. Each communication pathway is locally optimized for its specific purpose.
3Device complexity
If single in-band communication manner is adopted, then device complexity is reduced, but demodulation success rate decreases due to poor communication quality
Solution Approach 1:
The patent implements a dynamic communication system that automatically selects the appropriate communication mode (in-band or out-of-band) based on the data type and transmission requirements. This dynamic adaptation allows the system to maintain simplicity in normal operation while achieving high reliability when needed, without requiring complex manual configuration.

AI summary
A communication method, device, and equipment for wireless charging and storage medium, and belongs to the technical field of wireless charging. The method includes: transmitting a data packet to a wireless power transmitting device by in-band communication, if emergency data needs to be transmitted during a wireless charging process; and transmitting the data packet to the wireless power transmitting device by out-of-band communication, if non-emergency data needs to be transmitted during the wireless charging process; wherein a requirement for a transmission delay of the emergency data is higher than a requirement for a transmission delay of the non-emergency data.
