Charging Device Independent Power Control via Battery Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging technologies lack independent charging control, relying solely on the power supply source to manage charging, which fails to optimize battery health and efficiency.
Innovation Solution
A charging device and system that acquires the remaining battery amount of a terminal and controls power supply based on set thresholds, allowing for independent charging control via cable or wireless transmission, including a receiver for instructions to start or stop power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power supply source controls charging, then charging control is simple, but charging control independent of the power supply source cannot be performed
Solution Approach 1:
The patent introduces a charging device as an intermediary component between the power supply source and the terminal. This charging device includes a power supply controller that independently manages charging operations, receiving power from the power supply source and controlling power delivery to the terminal based on battery status. This mediator enables independent charging control without requiring the terminal or power supply source to directly manage the charging process.
Solution Approach 2:
The patent segments the charging system into distinct functional components: the power supply source, the charging device (with its own controller), and the terminal. By separating the charging control function into an independent charging device, the system achieves both simplicity in individual components and versatility in overall control capability.
2Productivity
If continuous power supply is provided, then charging speed is fast, but battery overcharging and reduced battery life occur
Solution Approach 1:
The patent implements a feedback mechanism where the power supply controller continuously monitors the remaining battery amount of the terminal and adjusts power supply accordingly. When the battery reaches a predetermined threshold (e.g., 100% or 80%), the controller automatically stops or reduces power supply, preventing overcharging. This feedback loop enables both fast charging when needed and battery protection when full.
Solution Approach 2:
The charging system dynamically adjusts power supply levels based on real-time battery status. The power supply controller can switch between different charging phases: high-speed charging when battery level is low, reduced power when approaching threshold, and complete stop when full. This dynamic adjustment optimizes both charging speed and battery longevity.

AI summary
This invention enables to perform charging control independent of a power supply source. A charging device supplies power to a terminal via a cable or wirelessly. The charging device that supplies power to the terminal via a cable or wirelessly includes a remaining battery amount acquirer and a power supply controller. The remaining battery amount acquirer of the charging device that supplies power to the terminal via a cable or wirelessly acquires the remaining battery amount of the terminal. The power supply controller of the charging device that supplies power to the terminal via a cable or wirelessly controls the start and stop of supply of power to the terminal based on the acquired remaining battery amount.
