1Loss of energy

If a DC energy storage component is used to power AC devices, then energy efficiency and cost are improved, but compatibility with AC devices and proper power mode selection becomes problematic

Engineering Contradiction:

Improveenergy efficiencyVSAvoidcompatibility with AC devices

Core Design Contradiction:

Loss of energyVSAdaptability or versatility

Solution Approach 1:

The system dynamically switches between DC and AC power output modes based on real-time detection of device parameters. The controller adjusts the power delivery mode (DC or AC) according to the connected device's requirements, enabling the energy storage system to adapt its output characteristics dynamically rather than being fixed in one mode.

Inventive Principle:

Solution Approach 2:

The system changes its output parameters (voltage, current, frequency) based on detection results. When a device is connected, the detection unit measures parameters such as impedance and power requirements, then the controller adjusts the output parameters accordingly to match device specifications, ensuring proper compatibility while maintaining energy efficiency.
