Generally speaking, load current and leakage current clamp meters are used in the same basic manner. First, if your clamp meter allows you to choose DC or AC current, choose the type of current that’s appropriate for the circuit you wish to measure. Then set the measurement range based on the magnitude of the current you’ll be measuring.
The charging pile determines whether the power supply interface is fully connected with the charging pile by detecting the voltage of the detection point. Multisim software was used to build an EV charging model, and the process of output and detection of control guidance signal were simulated and verified.
