When charging station operators (CPOs) deploy a chain of unmanned electric vehicle (EV) charging stations, system network interruptions also arise, and the frequency of on-site troubleshooting remains high, which becomes a management problem.
Moxa integrates Moxa OnCell G4302-LTE4 cellular routers and MRC Quick Link services into each charging station, allowing operators to easily manage and monitor all systems.
Let's take a look at how Moxa does it.
Customer needs and challenges
A charging pile operator (CPO) has deployed a chain of unmanned electric vehicle (EV) charging stations.
How to easily manage and monitor all systems and minimize the frequency of on-site troubleshooting when the system network is interrupted is a difficult problem that operators must face. The following are specific system requirements:
【System Requirements】
◎ Reliable data collection ensures stable operation of electric vehicle charging systems
◎ Online management is simple and safe, and can monitor and maintain multiple systems at the same time
◎ Easy-to-use electric vehicle charging system diagnostics and troubleshooting tool
Moxa Solution
Moxa Simplify remote connectivity by integrating the OnCell G4302-LTE4 cellular router and MRC Ouick Link service into each charging station, making remote maintenance of electric vehicle charging systems simpler and more efficient.

The key to achieving sustained and stable operation of electric vehicle charging infrastructure is to carry out monitoring and maintenance work by building secure and reliable remote connections.
- Separate the data of charging service operation and EV supply equipment maintenance.
- Non-IT personnel of charging station operators can easily set up and remotely access equipment on demand through MRC Quick Link service.
- Cloud-based MRC* Quick Link function ensures remote management and service scalability
* MRC is Moxa Remote Connection Kit
The OnCell G4302-LTE4 router stably transmits the data of each charging system to the charging station operator's cloud platform, ensuring that charging services are available at all times.
Dual SIM, LTE/Ethernet to WAN redundancy and GuaranLink cellular auto-recovery further enhance operational reliability.
OnCell G4302-LTE4 can also be used as an MRC gateway to maintain electric vehicle supply equipment (EVSE), enabling charging station operators to remotely monitor all connected systems through the MRC cloud and track the status of charging infrastructure.
- The MRC server supports charging pile operators and EV power supply equipment suppliers to access the MRC gateway through customized access control to conduct power supply equipment diagnosis and troubleshooting.
- Charging pile operators can remotely access and manage MRC access control during specified time periods through dedicated access accounts.
- EV power supply equipment engineers can use MRC client software to remotely access equipment anytime and anywhere for troubleshooting.
