Hi Team,
The customer learned that the CC1 filter is recommended for charge integration. It outputs a value every 250ms, which is converted to a frequency of 4Hz. When cooperating with the inverter to output 220Vac/50Hz for testing, he found that the current waveform of the battery pack would follow the frequency of the AC output. So, the sampling frequency of the current cannot satisfy Nyquist's theorem, that is, the sampling frequency needs to be twice the signal frequency.
The specification sheet states that integration through charges can be provided in the form of 64 bit values using the 0x0076 DASTATUS6() subcommand. What sampling frequency was used to obtain this charge integral?
Best regards,
Annie Liu
