Description
Hioki BT5525 Tester for High-Speed Battery Insulation Testing
The Hioki BT5525 Battery Insulation Tester is a cutting-edge solution for battery manufacturers seeking reliability, safety, and efficiency. Designed specifically for battery production lines, the BT5525 identifies contamination that could lead to latent defects, preventing potential hazards such as fires or accelerated battery degradation.
Break Down Detection (BDD) for Safety and Quality
The BT5525 incorporates a proprietary BDD function, which monitors minute voltages and currents to detect internal short-circuits caused by metallic contamination before electrolyte filling. By catching defects early, manufacturers can prevent defective batteries from reaching the market, enhancing product safety, durability, and performance.
High-Speed, Stable Insulation Resistance Testing
Leveraging Hioki’s decades of insulation tester design expertise, the BT5525 ensures consistent testing even in electrically noisy environments. Its contact check function reduces false negatives by confirming proper instrument connection to battery terminals. With a maximum test voltage of 500 V, it is suitable for both individual cells and battery modules or packs.
Accelerated Production with Fast Charging/Discharging
The BT5525 supports high-speed charging up to 50 mA and rapid residual discharge up to 40 mA, boosting testing speed by up to 25 times compared to previous models. This allows manufacturers to increase production throughput without compromising accuracy.
Integration and Data Analysis
Compact and easily integrable, the BT5525 fits seamlessly into automated battery production systems. Its PC application enables waveform visualization, CSV data export, and detailed analysis of voltage and current fluctuations, facilitating optimized test line setup and precise judgment criteria.
