Abstract

An energy storage apparatus (10) and an energy storage system (100) are provided. The energy storage apparatus (10) is configured to be electrically connected to a power conversion system (20), where the power conversion system (20) is capable of cooperating with M energy storage apparatuses (10), a rated output power of the power conversion system (20) is P, an energy of the energy storage apparatus (10) is Q, a duration for the energy storage apparatus (10) to discharge from a fully charged state to a fully discharged state is A, satisfying: 0.7 ≤ P/(M * Q/A) ≤ 0.99. With P/(M * Q/A) ≤ 0.99, it is ensured that the power of all energy storage apparatuses (10) cooperating with the power conversion system (20) maintains sufficient margin relative to the power of the power conversion system (20), eliminating the need for capacity supplementation of the energy storage apparatus (10) over a long period, achieving long-term reliability of the energy storage apparatus (10). With P/(M * Q/A) 2: 0.7, it is ensured that the margin of the power of the energy storage apparatus (10) relative to the power of the power conversion system (20) is not excessive, reducing power waste and improving the economic efficiency of the energy storage apparatus (10). Thus, power matching between the energy storage apparatus (10) and the power conversion system (20) is improved.
