摘要： An apparatus to perform series and parallel arc fault current interruption (AFCI). The apparatus includes a resistive element configured to sense a load from which a current signal is generated, a first detection unit configured to output a first signal based on the current signal, and a microcontroller configured to decompose at least the first signal via discrete wavelet transforms to thereby obtain discrete wavelet coefficients, and to generate a trip signal when the discrete wavelet coefficients indicate that a threshold condition for trip signal generation are satisfied.

摘要： Methods and systems for use in charging an electrically powered vehicle are disclosed. One example method includes transmitting, by a charging station, an authorization request message to a charging system host, receiving a return message from the charging system host in response to the authorization request message, and transmitting, by the charging station, a charge terminate message to the charging system host in response to a charge terminate event. The authorization request message includes a charging station identification and a vehicle identification of a vehicle coupled to the charging station. The charge terminate message includes the charging station identification and at least one of a vehicle connection time and a charge time.
