Typedef Documentation

◆ SOF_CURRENT_LIMITS_s

struct definition for 4 different values: in two current directions (charge, discharge) for two use cases (peak and continuous)

◆ SOF_CURVE_s

typedef struct SOF_CURVE SOF_CURVE_s

struct definition for calculating the linear SOF curve. The SOF curve is voltage, temperature and charge/discharge dependent.

Function Documentation

◆ SOF_Calculation()

void SOF_Calculation ( void  )

triggers SOF calculation

TODO

Here is the call graph for this function:

◆ SOF_Init()

void SOF_Init ( void  )

initializes the area for SOF (where derating starts and is fully active).

Pseudocode for linear function parameter extraction with 2 points:

  • slope = (y2 - y1) / (x2-x1)
  • offset = y1 - (slope) * x1
  • function y= slope * x + offset
