Table 3 OCV computation from SOC

Open circuit voltage from state of charge algorithm
1. Determine the boundary conditions: if (x_m0 < 0) use the minimum pre-calculated OCV. else if (x_m0 > 1) use the maximum pre-calculated OCV else if (0 < x_m0 < 1) compute OCV using steps 3 to 5. 2. Find the Index Index = int(200x_m0) 3. Find the difference (D) and offset (S) D = I – 200x_m0 S = 1 - D 4. Compute the OCV using temperature (T) OCV = (OCV₀[I] ∗ S + OCV₀[I + 1] ∗ D) + T ∗ (OCV_rel[I] ∗ S + OCV_rel[I + 1] ∗ D)
