Battery Management Systems (BMS) and Electric Vehicle (EV) Battery Testing

The HIOKI Battery Cell Voltage Generator SS7081-50 incorporates a DC power supply for 12 cells, voltage and current meters, and a simulated relay in a single housing. It can be connected to the BMS board as a battery cell simulator for testing. In addition, cell balancing, charge/discharge simulation, and abnormality detection confirmation are possible by connecting to PC via LAN cable and using the supplied application. Up to 1kV (17 units) can be supported by adding additional units and connecting each cell in series.

The Chroma 19052 is suitable for AC/DC/IR Hipot testing and insulation resistance (IR) measurements. Featuring an easy-to-operate front panel and clear digital display. User-friendly controls allow for test parameters and limits to be set easily without the high voltage activating.

Achieve long service life battery modules by measuring reaction resistance. Hioki benchtop battery testers support simultaneous high-speed measurement in the ever-expanding production lines of increasingly larger lithium-ion low-resistance batteries. The BT4560 battery impedance tester measures the impedance of lithium-ion batteries using the low-frequency AC-IR measurement method without charging and discharging the battery, substantially reducing the time needed to inspect the internal resistance of battery cells.

• Low-frequency AC-IR measurement (*1): Measure the reaction resistance of a battery
• Extremely reliable measurements for low-impedance batteries (*2)
• Circuit configuration highly tolerant of contact and wire resistance to provide stable measurements
• Voltage measurement function equivalent to 6-digit DMM (± 0.0035% rdg.)

A high-voltage battery tester (1000V maximum input voltage) for measuring EV and PHEV battery packs. 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 1000V.

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

The 2450 is Keithley’s next-generation SourceMeter Source Measure Unit (SMU). An instrument that truly brings Ohm’s law (current, voltage, and resistance) testing right to your fingertips. With an innovative, graphical user interface (GUI) and advanced, capacitive touchscreen technology, usage is intuitive and engineers and scientists can learn faster, work smarter, and invent easier.

The Keithley 2450 SMU is ideal for testing battery charge/discharge cycling and battery energy efficiency.

Get a high-performance digital multimeter without a huge investment. The Keithley DMM6500 is a touchscreen bench 6.5 digit multimeter that provides more measurement capability, including transient capture, data visualisation, and analysis, than many industry 6.5 digit multimeters at the same price point.
