Who will pay for the expansion if the battery capacity is not enough?

It should be paid by the owner of the community.

If the capacitance of the residential area cannot meet the power load of the charging pile, the transformer can be expanded. This community belongs to this situation, and the property rights of distribution facilities belong to the owners.

As a manager, small property rights have the responsibility and obligation to manage the future increase in transportation capacity as a whole. The owner of the newly-built charging pile in the early stage shall bear the capacity increase fee. From the perspective of assisting government units to vigorously promote the construction of new energy vehicle charging facilities, the property will introduce public intelligent charging facilities in the follow-up management process to reduce the charging pressure in the community.
