Solution Overview
Problem
Conventional methods for verifying the control function of secondary battery management devices are time-consuming and prone to human error, leading to low reliability and varying results depending on the developer's proficiency, especially when the devices are not set under the same hardware conditions as the actual use environment.
Innovation Solution
A function verification system that includes a computer with a verification program, an input/output interface, and a voltage simulator, which generates and monitors control signals to simulate the operation of external devices like relay switch modules and cooling fan modules, allowing for reliable verification without requiring the same hardware conditions as the actual use environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification is performed by developers under preset testing items, then verification can be conducted, but it takes a lot of time and is prone to human error
Solution Approach 1:
The patent creates a virtual copy of the secondary battery and its management device through software simulation. The verification program generates virtual secondary batteries with configurable parameters (voltage, current, temperature, state of charge) that replicate real battery behavior without requiring physical hardware. This virtual model enables automated verification processes that are both faster and more reliable than manual testing.
Solution Approach 2:
The patent replaces the manual mechanical verification process with an automated computer-based system. The verification program automatically generates test cases, executes verification sequences, monitors control signals, and produces verification results without human intervention. This substitution eliminates human error and significantly reduces verification time while maintaining comprehensive test coverage.
2Reliability
If verification is performed manually by developers, then verification can be conducted, but the result varies depending on the verification proficiency of the developer
Solution Approach 1:
The verification system is designed to be self-executing with the verification program automatically generating test conditions, executing verification sequences, monitoring control signals, and producing results without requiring expert human intervention. The system includes built-in logic for generating appropriate test cases based on configurable parameters and automatically interpreting verification outcomes, making it accessible to users regardless of their proficiency level.
Solution Approach 2:
The verification program provides a universal interface that handles multiple verification scenarios through a single unified system. It can verify different control functions (relay switch module, cooling fan module) by configuring virtual battery parameters and test conditions, eliminating the need for separate specialized procedures for each verification type.
3Measurement precision
If the secondary battery management device is set up under the same testing conditions as the actual use environment, then accurate verification can be performed, but it requires identical hardware conditions which reduces adaptability
Solution Approach 1:
The patent enables verification under varying parameter conditions through the voltage simulator and configurable virtual battery parameters. The system can simulate different voltage levels, current conditions, temperature ranges, and state of charge values without changing physical hardware. This allows comprehensive verification across multiple operating conditions while maintaining the same hardware setup, thereby improving both accuracy and adaptability.
Solution Approach 2:
The verification program acts as an intermediary between the physical hardware and the verification process. It translates real hardware capabilities into virtual test scenarios, allowing the system to verify control functions under simulated conditions that match actual use environments without requiring identical physical setups. This intermediary layer decouples the verification accuracy from hardware specificity.

AI summary
The present disclosure relates to a system capable of verifying an external device control function of a secondary battery management device, and that is coupled with an input/output terminal unit, a communication terminal unit and a measurement terminal unit of the secondary battery management device. The system generates conditions causing operation of the external device, monitors whether an external device control signal is being output normally through the input/output terminal unit of the secondary battery management device, and verifies whether current operation state information for the external device is being maintained exactly in a memory element. The system may include an interface unit to convert the format of the data being transmitted between the computer and the secondary battery management device, and a voltage simulator capable of artificially generating a voltage signal representing the voltage, current and temperature level of the secondary battery and applying the same to the measurement terminal unit.
