Data Sheet Model 2550 - 1

Universal High Voltage Battery Controller for analysis, testing and diagnosis Preliminary data sheet Highlights V oltage measurement of 0 … 100 VDC to 0 … 900 VDC A C resistance range (impedance) 0 … 100 mΩ and 0 … 100 Ω R esistance measuring range 0 … 1 mΩ and 0 … 3 Ω F requency range 1 Hz … 1 kHz E xtremely compact, easy to operate Areas of application The extremely compact, universal battery controller is one of the world's first devices for measuring the spectral impedance of low and high voltage battery systems. It is predestined for troubleshooting in development/laboratory or manufacturing areas, for analyzing operating behavior in the test phase or for “rapid diagnostics” in the support area. Irrespective of the technology, batteries or accumulators can be tested in a reliable, fast and safe way. S tandard battery tests T arget/actual comparisons D iagnosis function (status determination) B attery analyses Product description The model 2550 universal battery controller operates in accordance with the well-tried four-conductor measuring method, and combines the functionality of a battery tester and a battery analyzer, making it possible to carry out rapid testing of batteries and accumulators irrespective of the technology. As well as high-voltage batteries, low voltage batteries (e.g. 12 VDC, 24 VDC or 48 VDC) can also be measured and diagnosed. The power is supplied and the measurements are read out via the galvanically isolated USB interface. Parameterization, visualization and operation take place via the intuitively operated PC software. The battery test function records the battery voltage and the internal resistance at a fixed frequency. An OK/NOK statement can be derived by means of comparison with target values. The charge status and capacitance (health) can be diagnosed by comparing the battery data. Signs of aging can be detected at an early stage in this way by examining changes over time. With the battery analysis function, the battery voltage and also the internal resistance can be measured via the frequency (spectral impedance). Other battery parameters can be derived using the frequency curve, e.g. the model parameters of the equivalent circuit, from which conclusions can be drawn about the load behavior of the battery. For example, information about damage can be obtained via deviations of the curve from characteristic values. burster – Technical changes rese

Calibration / test interval We recommend periodic checking at 12 monthly intervals. To do this, please send the device to us. Principle of operation The battery controller operates in accordance with the four-conductor method (Kelvin connection) and has 4 connections for impedance measurement: 2 connections for power input (Force + and Force -) and 2 connections for voltage measurement (Sense + and Sense -). The battery controller applies an AC current IAC that is relatively small in relation to the load current to the test object (battery, accumulator), and measures the resulting voltage...
