Patent number: 9583961Abstract: An intellectual power storing system comprises an indoor-controlling device and a battery array which are arranged in a building. After booting, the indoor-controlling device receives power from a power company to be an initial power to provide to an indoor apparatus in the building. The indoor-controlling device also receives power from a self-generated power apparatus, and transforms the received power to store to the battery array. When stored power of the battery array reaches a threshold, the indoor-controlling device receives power from the battery array to provide to the indoor apparatus, and stops to receive power from the power company. The battery array in the present invention comprises a plurality of the batteries which are integrated into a decoration of the building respectively.Type: GrantFiled: January 3, 2015Date of Patent: February 28, 2017Assignee: KERTIES INTERNATIONAL CO., LTDInventors: Tsung-Yin Hsieh, Shoei-Lai Chen
