CE 2W OCPP Controller Module Ethernet AC Charge Controller
1. Overview
PCA1601-429-D type OCPP module is a standard controller for client charging piles developed by our company that meets the OCPP1.5 / OCPP1.6-J / OCPP2.0 standards of the OCA Alliance. It has PWM charging guidance, plug-in PD detection, RS-232, RS-485, temperature detection, contactor control, LED indicator, USB and other functions and interfaces. The communication protocol can be customized according to customer requirements. It is suitable for AC/DC charging piles for electric vehicles.
Through our OCPP controller module, we can help customers easily realize the OCPP cloud platform control and management function through AC charging piles.PCA1601-429-D OCPP module not only has the OCPP client communication function, but also has the whole pile control function. We combine the OCPP communication function and the MODE3 controller into one to reduce the size of the controller as much as possible.
Customers only need to configure a simple B-type leakage protector, AC contactor, RFID card reader, display, etc.
To realize the function of European standard and American standard AC pile. Through our controller, each component is modular for the convenient after-sales maintenance.
PCA1601-429-D type OCPP module is composed of CPU unit, communication unit, network unit and power supply. It can be connected with peripherals such as credit card machines, meters, pile controllers. It has the feature of display controlling, local list storage, smart charging, low power standby and so on. Meets OCPP-1.5 SOAP, OCPP-1.6 / 2.0 JSON message transmission standard requirements.
The main functions are as follows:
1, Connection function with display;
2, Member card system and super members;
3, Ethernet, 4G, WIFI etc. networking functions
4, OCPP core functions
5, OCPP Offline local white list management6, OCPP Appointment function
