JH8808A Battery Protection Board Test Platform
This device is used for safety testing of lithium‑battery protection boards, verifying that all functional parameters fall within acceptable ranges. It provides operators with a standardized testing protocol, helping to boost production efficiency and streamline quality control. The system is compatible with commonly available protection board types, supporting configurations such as shared positive terminals (with separate outputs), shared negative terminals (with separate outputs), and combined charge‑protection–discharge‑protection modes. This product is primarily employed in production testing, incoming‑material inspection, quality assurance, and R&D experimentation.

I. Scope of Application
This device is used for safety testing of lithium‑battery protection boards, verifying that all functional parameters fall within acceptable ranges. It provides operators with a standardized testing protocol, helping to boost production efficiency and streamline quality control. The system is compatible with commonly available protection board types, supporting configurations such as shared positive terminals (with separate outputs), shared negative terminals (with separate outputs), and independent charge‑protection and discharge‑protection circuits. This product is primarily employed in production testing, incoming‑material inspection, quality assurance, and R&D experimentation.
II. Equipment Environmental Requirements and Technical Specifications
2.1 Power Supply: AC voltage 220 V ± 10%, frequency: 50 Hz ± 10%;
2.2 Ambient temperature: 10–45°C;
2.3 The environment shall be free from severe vibrations and the presence of corrosive gases, as well as flammable or explosive gases.
III. Introduction to the Model
3.1 Rapid Testing: Based on the protection board’s design parameters, this method conducts rapid tests at the upper and lower limits of the device’s output specifications, enabling battery‑pack manufacturers and power‑battery producers to perform large‑scale, high‑speed quality checks before shipment. It is suitable for testing protection boards across a variety of hardware architectures as well as certain software‑based solutions.
3.2 Quick‑Test Mode: A proprietary test mode in which the device measures the protection board’s delay time and, based on the manufacturer‑specified test speed, rapidly acquires the protection board’s data. The test speed is moderate, and the results are displayed, making this mode ideal for applications where rapid, coarse‑grained data are needed.
3.3 Precision Testing: This feature enables accurate measurement of the precise values of all functional parameters of the power battery protection board, with an accuracy of ±1 mV, facilitating sample debugging and development and providing R&D personnel with a standardized tool for rapid testing.
3.4 Laboratory Mode: Independently sets the voltage of a single cell string, simulating variations in single-cell battery voltage within the range of 0.5–5 V, and supports configuring conditions for cell balancing, overvoltage, and undervoltage. It also simulates charge–discharge functions, allows selection of either charging or discharging mode, evaluates whether the MOSFET is off or on, and enables real-time monitoring of the current flowing through each cell string during operation.
