IEEE Approved Draft Recommended Practice for Performance Testing of Electrical Energy Storage (EES) System in Electric Charging Stations in Combination with Photovoltaic (PV)

Performance testing of electrical energy storage (EES) system in electric charging stations in combination with photovoltaic (PV) is covered in this recommended practice. General technical requirements of the test, the duty cycle development, and characteristics are given. Based on these, detailed test protocol based on duty cycle, such as stored energy, roundtrip efficiency, step response time, ramp rate, and duty cycle roundtrip efficiency, etc. are provided.
