Solution Overview
Problem
Existing offline dummy load detectors for lead-acid storage batteries in data centers disconnect the battery from the power supply system for charge and discharge detection, leading to a failure of the backup power supply function and energy waste.
Innovation Solution
An online detection apparatus that connects the storage battery in parallel with the power supply, using a control unit to send a boost enable instruction to a discharge circuit, allowing the battery to enter a discharge state while monitoring its performance without disconnecting it from the power supply, thus enabling continuous energy use and functional redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If offline dummy load detection is used, then battery performance can be detected, but the backup power supply function fails and energy is wasted
Solution Approach 1:
The patent introduces a detection circuit as an intermediary component that can measure battery performance parameters (voltage, current, temperature) without requiring physical disconnection of the battery from the power supply system. This intermediary measurement system enables offline-level detection precision while maintaining online backup functionality.
Solution Approach 2:
The patent replaces the mechanical disconnection approach (physically disconnecting the battery for offline testing) with an electrical/electronic measurement system that can detect battery parameters through circuitry while the battery remains connected and functional in the power supply system.
2Measurement precision
If offline dummy load detection is used, then battery charge and discharge can be tested, but energy is wasted
Solution Approach 1:
The patent enables the battery to continue serving its primary function (power supply) during the detection process. The battery powers the system normally while the detection circuit simultaneously monitors its charge and discharge characteristics, eliminating the need to disconnect the battery for testing and thus preventing energy waste.
Solution Approach 2:
The patent ensures continuous useful action by maintaining the battery's power supply function throughout the detection process. The battery remains connected and operational, continuously providing power to the system while undergoing performance monitoring, rather than being disconnected and idle during testing.
