Remote Maintenance for EV Charging Systems

A charging point operator (CPO) deployed a chain of unmanned electric vehicle (EV) charging stations. By integrating Moxa’s OnCell G4302-LTE4 cellular routers and MRC Quick Link service into each charging station, the CPO was able to manage and monitor all systems with ease. This solution also minimized on-site troubleshooting when a system goes offline.

System Requirements

• Reliable data acquisition to sustain EV charging operations

• Simple and secure online management for monitoring and maintaining multiple systems at once

• Easy-to-use tools for diagnosing and troubleshooting EV charging systems

Setting up reliable and secure remote connectivity to monitor and maintain EV charging infrastructure is key to enabling non-stop operations. To ensure 24/7 charging services, the OnCell G4302-LTE4 routers provide stable data transfer from each charging system to the CPO cloud. The dual SIM, LTE/Ethernet-to-WAN redundancy, and GuaranLink cellular auto-recovery features further enhance operational reliability.

For EV supply equipment (EVSE) maintenance, the OnCell G4302-LTE4 acts as an MRC gateway, allowing the CPO to remotely monitor all connected systems through the MRC cloud and keep track of the charging infrastructure status.

• The MRC server allows customizable access control for the CPO and EVSE provider to access MRC gateways for EVSE diagnostics and troubleshooting

• MRC access control is managed by the CPO via dedicated access accounts and time slots for remote access

• EVSE engineers can use the MRC Client software to remotely access EVSE for troubleshooting from anywhere
