Overview¶
The AL-4010 is an SLSC module designed to be used with a NI SLSC chassis (SLSC-12001). It provides a total of 6 channels that are capable of emulating 6 battery cells and the dielectric strength between the channels is 60V and the dielectric strength between the board and the NI SLSC chassis is 1000V, and by having multiple AL-4010 boards installed they can be connected in series so the number of cells connected in series is therefore only limited by the sum of single cell voltages.
The AL-4010 can sink and source in all quadrants and to minimize internal power losses the positive and negative operation voltages are variable and operate dependent on the output voltage.
In the case of short circuit, the board can manage 5A (10A peak for 100ms).
In the case when the voltage from external source / BMS is higher than the voltage output in the cell this results in current flowing from the external source/BMS to the AL-4010 current sink.
In the case when the voltage in AL-4010 is higher than the voltage from the external source / BMS this results in current flowing from the AL-4010 into the external source / BMS.
It is possible to calibrate the system, calibration and adjustment are both possible without removing the system from its installation. Measurement accuracy is guaranteed within the specified operating- and temperature range.
Possible System Architecture¶
The first diagram below shows how a system could look like with a real battery connected to the battery management system, whereas the second diagram shows how a system could look like when using ALIARO’s xMove Battery Cell Simulator.
