New Hioki ST5680 DC Hipot Tester

Hioki Releases the new ST5680 DC Hipot Tester

The multifunctional ST5680 DC Hipot Tester is the answer to safety and quality control requirements of latest battery modules and packs. Degradation of EV batteries can lead to serious accidents, in extreme cases even to fire. To meet the rigorous reliability and safety requirements, battery module and pack manufacturers are improving the insulation performance of their products. Consequently, an extremely low current resolution for leak current measurements is required to correctly judge the battery module or battery pack quality. Traceability is essential especially in the automotive industry with increasingly strict and mandatory testing requirements. This requires saving quality test results as proof after quality inspections. Also, for other industries like the solar industry the ST5680 can be used for type approval testing because of the test voltage of 8 kV.

The multifunctional ST5680 DC Hipot Tester is the answer to all these requirements.

• Highest leakage current resolution: 0.001 μA With a resolution of 0.001 μA, ST5680 is the most sensitive hipot tester on the market suitable for effective PASS/FAIL judgements of the latest generation battery packs.
• Fast sampling arc discharge waveform display: 5kS/s (quality assurance) The arc discharge waveform display allows to determine whether the arc discharge has caused permanent damage to the insulation of the battery pack or not.
• Traceability: Recording of trend data of measured voltage, current, resistance Trend data of the entire test cycle is recorded, providing the evidence that the pack passed the end-of-line inspection successfully, which can help avoid potential liability claims.
• 2-wire contact check function: reliable testing to make sure that the DUT is connected correctly, a contact check is performed after the measurement. This prevents possible erroneous PASS results and guarantees a valid test
  result.
• Breakdown Voltage test according to IEC 60243-1 Part 2
• 8 kV test voltage: for the solar industry According to the IEC61730-2 safety standard, Class II PV modules used in 1,500V systems, must pass an 8 kV type approval test.
