Comparison of AC and DC charging methods
The main types of charging for electric vehicles (EVs) are alternating current (AC) and direct current (DC), which differ in terms of efficiency, speed, and impact on the grid. The following is a deta
• Main-standby power supply, self-returning;
• When any phase of the main power supply circuit fails (powe filure o phase lo , the switch is automaticly inputo the standby power supply ciouit which isusallythree-phase sampling, and the standby power supply is single-phase sampling;
• When the main circuit returns to normal, the switch automatically switches back to the main power supply Loop.
