1. A method for managing a distributed battery arrangement, wherein
the arrangement comprises a pool of battery assets; the method comprising allowing capacity limits to be set for the battery assets, wherein the capacity limits comprise
a first capacity limit defining minimum charge that is to be maintained in a battery asset; and
a second capacity limit defining maximum charge that should not be regularly exceeded; wherein
capacity falling between the first capacity limit and the second capacity limit is a usable capacity range, the method further comprising
centrally controlling usage of the usable capacity range of the battery assets for balancing and/or optimization tasks by
assigning a first part of the usable capacity range for up regulation of electric grid;
assigning a second part of the usable capacity range for charging optimization; and
assigning battery capacity above the second capacity limit for down regulation of electric grid.
