Hioki benchtop battery testers support simultaneous high-speed measurement of the internal resistance and battery voltage of EV and PHEV battery packs. The BT3564 Battery HiTester can measure pack voltage and total resistance, as well as bus bar resistance up to 1000 V.

• Measure high-voltage battery packs up to 1000 V
• Production line testing of high-voltage battery packs for EV, PHEV
• 0.1 μΩ to 3000 Ω internal resistance range (pack total resistance, bus bar resistance)
• Measure from 0 V DC to ±999.999 V DC (minimum resolution 10 μV)
• Optional measurement probe available for 1000 V and high-voltage battery packs
• Spark discharge reduction function
• Analog output function
