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.
