Fanway specializes in delivering efficient and reliable end-to-end PCB assembly services, precisely tailored to your unique requirements to accelerate your product success.
Substrates utilize FR-4 or high-frequency materials (such as Rogers 4350B).
Gold plating or OSP surface treatment is adopted to ensure contact reliability.
Key components, such as DC-DC modules, undergo 100% aging tests.
Charging Pile PCBA Motherboard are classified into two types based on charging mode:
AC charging piles and DC charging piles.
AC Charging Pile Circuit Board: This board converts grid AC power to DC power through the vehicle's On-Board Charger (OBC). Its core functions include:
CP Terminal Control: Communicates with the vehicle's BMS using PWM signals to monitor charging status (e.g., gun insertion, charging preparation, charging start). The working voltage is 12V/9V/6V with a frequency of 1kHz.
CC Terminal Detection: Confirms the charging gun connection status through resistance changes and determines output current capacity (e.g., a 1.5kΩ resistance corresponds to an 8A current).
Typical Parameters: Input 220V AC, output power 7kW/11kW, protection rating IP54.
DC Charging Pile Circuit Board: This board directly outputs high-voltage DC power. Its core modules include:
AC/DC Rectification and PFC Module: Converts three-phase 380V AC to high-voltage DC (750-850V) using active Power Factor Correction (PFC) technology, with efficiency exceeding 97%.
DC/DC Conversion Module: Adjusts voltage to the battery's required range (e.g., 200-920V) through LLC resonant topology and supports dynamic current control (up to several hundred amperes).
Typical Parameters: Input 380V AC, output power 30-120kW, integrated STM32F207ZET main control chip, supports CAN/RS-485 communication.
Community Charging Stations: Prioritize EMC performance (EN 61000-6-2 standard).
Highway Ultra-Fast Charging Stations: Must meet the insulation withstand voltage requirement of 2000V.
