... interferences. Findings – The experimental results indicate that AC interference makes the OCPP decrease and the −0.85 V/CSE criterion is not reasonable when there is AC interference. When the AC voltage is less than 6 V, the OCPP is approximately −900 mV/SCE, and when AC voltage is more than 7 V...

... solution with different AC interferences. Findings The experimental results indicate that AC interference makes the OCPP decrease. It was determined that the −0.85 V/CSE criterion is not appropriate when there is AC interference. When the AC voltage was less than 6 V, the OCPP was approximately −900 mV...
