Energy storage inverter patent application requirements

4 FAQs about Energy storage inverter patent application requirements

How many patents are there in energy storage system?

Firstly, using the “energy storage system” a total of 847,461 (n = 847,461) patents were found. Secondly, “battery” was used and a total of 272,904 (n = 272,904) patents were obtained.

Why should energy storage systems be integrated with the grid?

To ensure grid reliability, energy storage system (ESS) integration with the grid is essential. Due to continuous variations in electricity consumption, a peak-to-valley fluctuation between day and night, frequency and voltage regulations, variation in demand and supply and high PV penetration may cause grid instability .

How many patent documents are there in Lib ESS?

Among the key players in the grid-connected LIB ESS field, Evonik Degussa Gmbh of Germany has five patent documents which are class‑leading followed by Palo Alto Research Center Inc. of the United States and STEAG Power Saar GmbH of Germany having four patent documents each.

How are patent documents classified by legal status?

Patents documents by legal status The patents are classified into six different categories such as; Active, Pending, Discontinued, Inactive, Expired, and Unknown patents. The categorization of various patent documents in terms of legal status from the selected grid-connected LIB ESS fields is shown in Fig. 7.
