The basic principle of new energy automobile parts charging pile cable

As it relates to vehicle performance and cost, the integration and standardization of auto parts has always been the direction of the industry's efforts. To achieve rapid product iteration and platform application, standardization and integration are two major tools. The so-called integration refers to the integration of originally separate systems, thereby streamlining the number of automobile-related components, making them smaller, lighter, and more efficient.

However, what is the basic principle of charging piles? In fact, the AC pile only inputs the main power (220VAC or 380VAC) into the electric vehicle through the adapter, and then converts the AC to DC to charge the battery through the car charger. The DC charging pile converts the mains AC power into DC power, and then adjusts the output voltage and output current of the power battery on the vehicle through real-time communication with the BMS on the vehicle.

The on-board charger control circuit of new energy vehicles has the control field effect transistor switch, which communicates with the BMS, monitors the working status of the charger, and shakes hands with the charging pile. Wiring harnesses and standard parts are used to connect the main circuit and the control circuit, and to fix components and circuit boards.
