4.4 Step 4: Evaluation

Figure 4-10 shows different evaluation modes used for different conditions selected in Gauge_UserConfig.h.

Gauge Mode Setting Figure 4-10 Gauge Mode Setting

For different output modes, UART_OUTPUT means enabling data output through universal asynchronous receiver or transmitter (UART). Then, users can observe the battery running parameters on the GUI through USB to tool. NO_OUTPUT means terminating the UART data output.

The different detection modes are detailed in the following section. Detection data input mode is the common used mode. All the algorithm input is from real data tested by AFE. The input data of the communication data input mode comes from the GUI and the one cycle time limitation lies on the UART communication speed.
