Solution Overview
Problem
Existing power storage adapters face challenges in efficiently supplying power to multiple portable information handling systems, particularly when the battery capacity is insufficient to meet the combined power demands, leading to inefficiencies and increased power losses.
Innovation Solution
The power storage adapter performs a power state analysis to determine the battery capacity and power margin, selecting optimal power delivery states that minimize power loss and temperature rise, and establishes contracts to supply power efficiently between USB Type-C ports, ensuring efficient operation even when battery capacity is limited.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the power storage adapter supplies power to multiple portable information handling systems simultaneously, then the power delivery capability is improved, but the power loss increases
Solution Approach 1:
The power storage adapter dynamically adjusts the power delivery state for each port based on real-time conditions. The controller monitors battery capacity, power margin, and operational requirements to selectively establish power delivery contracts, optimizing the balance between serving multiple devices and minimizing power losses.
Solution Approach 2:
The system changes operational parameters by establishing different power delivery states with specific voltage and power levels for each port. By adjusting these parameters based on battery capacity and power margin calculations, the adapter optimizes power distribution efficiency while meeting device requirements.
2Adaptability or versatility
If the power storage adapter establishes power delivery contracts for multiple devices, then the versatility is improved, but the battery capacity management becomes complex
Solution Approach 1:
The controller implements feedback mechanisms by continuously monitoring battery capacity and power consumption levels. Based on this feedback, the system performs power state analyses to determine optimal power delivery configurations, ensuring that power contracts are established only when battery capacity is sufficient to meet combined device requirements.
Solution Approach 2:
The system performs preliminary power state analyses before establishing power delivery contracts. By evaluating battery capacity and power margin in advance, the adapter determines whether it can safely support additional devices, preventing over-discharge and managing battery resources proactively.
3Power
If the power storage adapter increases power delivery to meet device demands, then the power supply capability is improved, but the temperature rise increases
Solution Approach 1:
The adapter dynamically selects power delivery states that balance power supply capability with thermal management. By monitoring device power requirements against battery capacity and power margin, the controller adjusts delivery parameters to provide sufficient power while minimizing temperature rise through optimized voltage and current levels.

AI summary
A power storage adapter may use a method for efficient supply of power of multiple portable information handling systems. In particular, when electrical power is delivered from a battery to at least one of the portable information handling systems, the power storage adapter may deliver electrical power from the battery to another portable information handling system when the battery has sufficient battery capacity such that the power is supplied efficiently.
