The Geehy charging Station solution is feature-rich, safe and reliable, and easy to apply and develop. With the advantages of low power consumption, high performance, high integration, and high stability, the APM32-based industrial-grade MCUs are fully utilized in charging management, data communication, and processing of mainstream charging Stations. At present, our AC/DC charging Station solutions have been recognized by many customers and have been shipped in mass production.

AC Charging Station Solution

AC charging Station, a dedicated power supply device that uses conduction to provide AC power for electric vehicles with on-board chargers (OBC), includes a human-machine interaction unit, control unit, measuring unit, and safety protection unit, and is suitable for small pure electric vehicles or plug-in hybrid electric vehicles, which generally takes 3 to 8 hours to be fully charged.

The AC charging Station adopts APM32F407 series industrial-grade MCUs to realize control and communication transmission, which is a solution that provides the stable output and helps customers to quickly implement products. Through voltage and current detection, this solution can achieve continuous and effective power output. At the same time, it can intuitively read the information on the display panel, realize IoT terminal real-time communication, and analyze charging efficiency.

APM32F407 AC Charging Station Solution Advantages:

•  Based on Arm® Cortex®-M4 core

•  Operating voltage: 220VAC; rated output current: 32A

•  Support wireless video IC card, remote control, and QR code start

•  Integrated operation/fault status monitoring, charging metering, historical data recording, and storage

•  Connected IoT function to realize real-time terminal communication

•  The display panel can timely feedback information on the power, charging rate, charge percentage, and remaining charging time through voltage and current detection

The APM32F407 series MCUs can meet the above design requirements with rich peripherals for real-time HMI, ADC acquisition of high-voltage signals, PWM detection, reading and writing, data logging, and optocoupler control.
