Product Description
Electric Vehicle Lithium Battery Insulation Pulse Safety Test Equipment
Equipment Overview
During lithium battery core winding or lamination processes, issues like material dust contamination, uneven winding, and diaphragm breakage can create safety hazards that are difficult to detect. Current industry testing methods often have suboptimal detection rates for defective products.
This equipment applies 10-100ms high-voltage pulses to battery cells before electrolyte filling. By analyzing charging time, voltage parameters, and curve characteristics, it identifies open circuits, short circuits, and micro-short circuit insulation faults with exceptional speed and efficiency.

- Advanced Display & Storage: 8-inch TFT color LCD with voltage waveform display, zoom functionality, waveform storage via USB, and oscilloscope interface
Error Codes & Diagnostics
| Alarm Code | Alarm Type | Description |
|---|---|---|
| E01 | Open Detection | Test voltage reaches set voltage during OPEN detection |
| E02 | Rising Discharge Detection | Voltage drops to discharge detection level before reaching set voltage |
| E03 | Keep Discharge Detection | Voltage drops to discharge detection level after reaching set voltage |
| E04 | Set Voltage Not Reached | Test voltage doesn't reach set voltage within test time |
| E05 | Rising Drop Voltage Detection | Voltage drop exceeds set range when rising to set voltage |
| E06 | Keep Drop Voltage Detection | Voltage drop exceeds set range after reaching set voltage |
| E07 | Shortest Arrival Time Check | Test voltage reaches set voltage before shortest time |
| E08 | Longest Arrival Time Check | Test voltage reaches set voltage after shortest time |
Testing Advantage: Unlike AC withstand voltage or insulation resistance methods that can mask micro-short circuits, our pulse testing identifies defects before electrolyte injection while preventing damage to good products.
