For decentralized charging piles in residential areas or unit parking lots, LTE CAT 1 / CAT 4 cellular Serial 4G modem are widely used for networking connection. The charging pile control board is connected to a cellular modem through RS232 or RS485 ports, LTE CAT 1/CAT 4 cellular serial modem automatically dials up the network through the operator's 4G network and establishes a connection with the monitoring center of the charging operation company or charging station, thereby building a transparent transmission between the charging station and the monitoring center.

 

4G connectivity and remote management is more important for the charging station. 4G LTE (CAT 1 / CAT 4) modem can avoid and improve the following situations:

1/ Maintenance personnel cannot arrive at the station in time

2/ Different locations of maintenance & troubleshooting

3/ Save labor cost and improved customer experience

 

USR-G771-E 4G LTE CAT 1 Serial modem can connect to control board of charging pile by RS485 port and send all data to the monitoring center by 4G based on transparent transmission or Modbus.

The control center can monitor the voltage, current, power in real-time and also can check the status of each charging pile on the station. If there is an alarm or failure, staff can carry out maintenance in time.

 

4G LTE CAT 1/ CAT 4 serial cellular modem supports remote update function based on the remote management system. It can realize the remote upgrade function to ensure that the charging pile control system is updated and the problem is quickly repaired. In response to unexpected failures of the charging pile, it automatically detects and uploads it to the control center in time.
