There are explicit instructions from BMW according to which the i8 should be recharged every 6 weeks in the event of longer periods of inactivity.

"No. 61 03 98 (387) Battery recharging intervals for stationary vehicles, battery charging calendar and battery hangers (12 V battery, high-voltage battery unit)"

Including a "BMW Battery Calendar" for non US models and a "Battery Log Form" for US models.
