Measure battery voltage and internal resistance simultaneously to confirm battery quality during shipping, acceptance and maintenance inspections. Execute this for various types of battery packs, such as those for EVs, PHEVs, and residential storage batteries, which are becoming increasingly high-voltage. Also measure the resistance of the bus bars of the battery stack safely.
Safely measure the voltage and internal resistance of high-voltage stacked battery packs with a dedicated probe.
The BT3564 is a battery tester for simultaneous measurement of internal resistance and battery voltage with a maximum input voltage of 1000 V. The L2110 probe for 1000 V can safely and comfortably measure wide terminal spaces, deep electrodes, and exposed bus bars of high-voltage battery packs.
The BT3564 is equipped with an analog output function for resistance measurement values. Combined with a recorder or logger, it enables long-term monitoring of the total resistance value. In battery pack quality evaluation tests, it is possible to simultaneously record the internal resistance and temperature of the battery.
