Electrolyte Sniffer Leak Detector<\/strong><\/p>\n\n\n\n

Precise leak detection for battery modules and packs in modern battery production.<\/strong><\/p>\n\n\n\n

Next-Level Quality Control in Battery Pack Manufacturing<\/h2>\n\n\n\n

The BES4000 opens up the possibility of localizing electrolyte leaks.
Based on the principle of electrolyte sniffing, it detects smallest traces of electrolyte vapors escaping from defective cells. This makes it possible to quickly and reliably locate leaks directly on assembled battery packs and modules\u2014without the need for chamber retesting.<\/p>\n<\/div>

During welding and handling, previously leak-tight cells can develop new micro-defects. The BES4000 identifies these leaks fast and with high accuracy, allowing targeted streamlined rework and thus saving significant cost. This saves time, materials, and resources while maintaining the highest safety and quality standards.<\/p>\n\n\n\n

How It Works: Electrolyte Sniffing Technology<\/h2>\n\n\n\n

The BES4000 uses the electrolyte solvent itself\u2014typically DMC or EMC\u2014as the tracer gas. Escaping vapors are detected by a highly sensitive sensor system that reacts within one second. This enables operators to pinpoint the exact location of leaks, even within complex battery pack assemblies.<\/p>\n\n\n\n

The Ideal Match for Cell Testing<\/h2>\n\n\n\n

Combined with the ELT series of electrolyte leak detectors, the BES4000 forms a closed feedback loop:<\/p>\n\n\n\n
