Test Setup

Use the following procedures before running this design board. The design is constructed as 52s pack configurations. To simulate the 1500V battery rack configuration, eight design boards need to be stacked to support 416s battery cells that are simulated by resistor ladders powered by a DC source. The LAUNCHXL-CC26X2R1 development kit acts as a wireless main (WM) node to transfer commands from the serial port tool to the wireless command and then to the wireless device (WD) nodes.

Figure 3-1 shows the test setup for 1500V battery rack. During the tests, neither the design board nor CC2662R-Q1 device is shielded with wireless headphone and mouse working nearby as 2.4GHz interference.
