Yes, the 70 - 80% SOC is the figure stated in BMW technical data. All part of intelligent alternator control (IGR). It is a reason why driving profile can have an impact on SOC, can drop below the 70 - 80%. Pays to give attention to how we harvest the most energy on the over-run. Lifting off the throttle completely, on the over-run/coasting, gives the alternator the maximum charging rate, adding to the SOC, hopefully towards 100%.
