Battery Pack Discharge and Charge Information Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic device systems with multiple battery packs, there is a need for effective control mechanisms to ensure appropriate discharging and charging of battery packs, as existing systems lack efficient methods to manage the status and usage of multiple battery packs, leading to potential power source instability and inefficient charging/discharging processes.
Innovation Solution
The system includes battery packs that output discharge and charge information based on voltage, temperature, and current conditions, allowing an electronic device to control discharge and charge operations accordingly, with a control unit selecting the appropriate battery pack for power source usage and charging priority based on this information.

Engineering Contradiction Analysis
1Duration of action of moving object
If multiple battery packs are mounted in an electronic device system, then the device can be driven for a longer time, but it becomes necessary to implement complex control mechanisms to manage discharge and charge operations appropriately
Solution Approach 1:
The battery pack autonomously monitors its own voltage, temperature, and current conditions, then outputs discharge and charge information without requiring complex external control. The control unit simply responds to these information outputs, enabling the battery pack to serve itself in managing its operational status.
Solution Approach 2:
The battery pack continuously outputs discharge and charge information based on its internal voltage, temperature, and current conditions. The control unit receives this feedback and adjusts discharge/charge operations accordingly, creating a closed-loop control system that manages multiple battery packs efficiently without complex mechanisms.
2Device complexity
If battery packs operate without proper control mechanisms, then the system is simpler, but power source stability and charging/discharging efficiency deteriorate
Solution Approach 1:
The patent replaces complex mechanical control mechanisms with an information-based control system. The battery pack outputs electrical signals (discharge and charge information) that directly guide the control unit's decisions, substituting physical control complexity with streamlined electrical signal processing.
3Productivity
If battery packs are charged without monitoring voltage, temperature, and current conditions, then the charging process is faster and simpler, but battery health and safety are compromised
Solution Approach 1:
The battery pack proactively outputs discharge and charge information based on monitored voltage, temperature, and current conditions before charging or discharging operations begin. This preliminary information allows the control unit to adjust charging parameters in advance, enabling fast charging while preventing battery damage through pre-emptive safety checks.
