Portable Terminal Battery Pack with Alternating Discharge Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable terminal battery packs struggle to extend battery use time due to high discharge rates, with previous technologies only marginally increasing battery life.
Innovation Solution
A battery pack with a power supply control unit that alternates power supply among multiple battery units, allowing one unit to supply power while others are in an idle state, thereby increasing residual capacity through a battery recovery effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If multiple battery units are connected in parallel to increase capacity, then battery use time increases, but discharge current increases and battery life decreases
Solution Approach 1:
The patent implements periodic switching between multiple battery units, where each battery unit alternates between discharge mode and idle mode. The power supply control unit switches the connection configuration of battery units in time periods, allowing some units to rest while others power the load, thereby extending overall battery life while maintaining continuous operation.
Solution Approach 2:
The patent divides the battery system into multiple independent battery units (first battery unit, second battery unit, etc.) that can be independently controlled. Each battery unit can be switched between different connection configurations (series/parallel) with the load, allowing selective discharge and rest periods for individual units, thus extending total system life.
2Power
If battery cells are connected in series to increase voltage, then power output increases, but discharge rate increases and reduces battery use time
Solution Approach 1:
The patent dynamically changes the connection configuration of battery units between series and parallel arrangements based on operational requirements. The power supply control unit adjusts the configuration in real-time, switching between high-power series mode and extended-life parallel mode, optimizing both power output and battery use time according to actual demand.
3Duration of action of moving object
If high-capacity battery is used to extend battery use time, then portability is compromised due to size and weight constraints
Solution Approach 1:
The patent divides the total battery capacity into multiple smaller battery units that collectively provide the required capacity. This segmentation allows for more flexible packaging and weight distribution, maintaining portability while achieving extended battery use time through the alternating discharge mechanism.
