External Power Management for Dual-Battery Medical Backup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing external energy storage power supplies for life-support medical equipment like ECMO devices face premature power cutoff due to overload protection when power demand exceeds supply, leading to reduced endurance and potential performance issues.
Innovation Solution
A real-time power management system that monitors and adjusts the duty cycles of multiple batteries and the external energy storage supply, switching to higher power batteries and parallel operation to maintain power without triggering overload protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the external energy storage power supply provides high power to meet the device requirements, then the power supply capability is improved, but the overload protection triggers and cuts off power supply
Solution Approach 1:
The patent combines multiple power sources (external energy storage power supply and internal battery) into a unified power management system. When the external power supply approaches overload threshold, the system automatically introduces internal battery power to supplement, ensuring continuous power delivery without triggering overload protection while maintaining reliable operation.
Solution Approach 2:
The patent implements dynamic power source switching and power contribution adjustment based on real-time monitoring of external power supply voltage and current. The system continuously adapts the internal battery's power contribution level, transitioning from full external power usage to hybrid power mode as needed, optimizing both power delivery capability and supply continuity.
2Duration of action of moving object
If the power consumption of the equipment is reduced to extend endurance, then the power supply duration is improved, but the performance and treatment effect are affected
Solution Approach 1:
The patent dynamically adjusts power consumption management based on available power supply conditions. When external power is sufficient, the system operates at full performance. When external power is limited, the system intelligently manages power distribution among components rather than uniformly reducing power, maintaining critical functions while extending endurance through optimized power allocation.
Solution Approach 2:
The patent changes operational parameters of power-consuming components based on power availability. Instead of simply reducing power consumption across the board, the system adjusts specific operational parameters (such as motor speed, pump flow rate, or processing intensity) to maintain therapeutic effectiveness while adapting to limited power supply conditions.

Data Source
AI summary
An external energy storage power management method, system, device and storage medium for life support equipment, when it is detected that the power of the external energy storage power is insufficient to power the whole machine, the duty cycle of the charging power of the two batteries is reduced. When the duty cycle of the charging power of the two batteries is reduced to 0, the power of the two batteries is detected. When the power of one of the batteries is sufficient to power the equipment, it is immediately switched to the high-power battery to power the equipment, and at the same time, the external energy storage power continues to charge the low-power battery.
