Through parallel function can support a variety of different power under test

Equipment through the parallel function can test different capacity, the object under test does not need to replace the equipment.Battery module manufacturers products have large capacity and small capacity of a variety of forms, if buy high power equipment, meet with small capacity battery test, measurement accuracy obviously inadequate;Used in parallel test, battery test can be set in accordance with the actual capacity of the channel is used in parallel, there will be no accuracy does not conform to requirements.

The use of the battery pack is fast and not specifications of the current state, through the working condition of simulation, the use of the battery status can be real reaction in the battery. Dynamic charge and discharge Waveform of simulation battery actual use, in the dynamic current mode (Waveform), maximum discharge and the maximum charging current switching time need only 10 ms Work step can be set inside a computer reads the specified storage current waveform of the Excel file Each channel can store 720000 points, for long time dynamic testing Interval: 10 ms - 100 s High frequency sampling measurement technology capacity test (more accurate) General battery test machine, the use of computer software based on the current value computing power.Because the data transfer technique have bottleneck, transmission speed limit, in view of the dynamic current capacity calculation, error will be large.Chroma increased by V/I sampling rate, and through the two integral method, provide better capacity calculation, accurate current change when the data is not missing, not affected by the data transfer rate. V/I 50 KHZ sampling rate (every 20 mu s sampling point) Piecewise integral mode operation: For I integral - electric capacity The V x I integral - energy
