Typedef Documentation

SOF_CURRENT_LIMITS_s

typedef struct SOF_CURRENT_LIMITS 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.

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
