• 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)
• Spark discharge reduction function
• Analog output function
• Optional measurement probe available for 1000 V and high-voltage battery packs

Maximum input voltage 1000V.High voltage battery tester for EV and PHEV.

The BT3564 simultaneously measures both internal resistance and battery voltage with an input voltage of up to 1000 V. This battery tester is perfect for shipping and receiving inspections of battery packs ranging from increasingly higher voltage EV and PHEV batteries to home storage batteries.

Probe supports 1000 V and high voltage battery packs (option)

Safely and smoothly measure high voltage battery packs with the 1000 V probe.

Built-in spark discharge reduction function

Spark discharges become more likely with measurements of higher voltages.The BT3564 limits the current that flows when contacting battery packs, thus reducing spark discharges.

Analog output function

Complete with a built-in resistance value analog output function. Combine it with a recorder or logger for total resistance value monitoring.
