Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing uninterruptible power supply (UPS) systems are labor-intensive, costly, and result in inaccurate service time estimates and energy wastage, as they require manual battery disassembly and reassembly, and are not capable of providing a stable power supply during testing.
Innovation Solution
An electricity management system comprising a data management unit, control unit, UPS apparatus, and power switch that automatically configures and conducts tests on UPS systems, measuring battery parameters and determining service power needs to ensure reliable power supply during blackouts, thereby reducing manual labor and energy wastage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual battery disassembly and reassembly is performed for testing, then battery capacity can be measured, but labor cost and testing time increase significantly
Solution Approach 1:
The system enables automatic testing where the UPS apparatus itself performs the discharge function through integrated control. The controller automatically monitors battery parameters, controls power switching, and generates test reports without requiring manual battery disassembly or external discharge equipment, making the system self-testing capable.
Solution Approach 2:
The UPS apparatus integrates multiple functions including power supply, battery testing, and capacity measurement into a single system. The controller can operate the UPS in different modes (normal power supply mode and discharge testing mode) and perform both protection functions and testing functions without requiring separate dedicated testing equipment.
2Measurement precision
If external discharge equipment is used for battery testing, then battery capacity can be measured, but equipment cost and system complexity increase
Solution Approach 1:
The invention extracts the testing function from external equipment and integrates it into the UPS apparatus itself. The controller within the UPS can independently control power switching, monitor battery parameters, and calculate capacity without requiring external discharge machines or specialized testing equipment.
Solution Approach 2:
The controller acts as an intermediary that coordinates between the power supply unit, battery unit, and monitoring systems. It automatically manages the testing process by controlling power switches, collecting battery data, and generating test results, eliminating the need for complex external testing equipment.
3Productivity
If automatic testing system is implemented, then testing efficiency improves, but system complexity increases
Solution Approach 1:
The invention merges the testing system with the existing UPS apparatus structure. The controller, power switches, and monitoring components are integrated into the same system architecture as the power supply and battery units, so automatic testing is achieved without adding separate complex testing equipment.
4Measurement precision
If conventional testing method is used, then battery capacity can be measured, but energy is wasted during discharge testing
Solution Approach 1:
The system incorporates feedback mechanisms where the controller continuously monitors battery parameters during discharge testing and uses this information to optimize the testing process. The system can adjust testing parameters based on real-time data and generate feedback reports that inform future testing and maintenance decisions.
Data Source
AI summary
A system and a method for electricity management are disclosed. The system includes a data management unit, a cabinet, a control unit, an uninterruptible power supply apparatus and a power switch. The cabinet is powered by an external power supply. When the data management unit sends a testing instruction to the cabinet, the control unit controls the power switch to shut down the external power supply such that the cabinet is powered by the uninterruptible power supply apparatus instead. The control unit measures a set of battery parameters of the uninterruptible power supply apparatus, computes a power supply capacity of the uninterruptible power supply apparatus according to the set of battery parameters, and returns the power supply capacity to the data management unit.
