Smart EV Charging Connectivity

Overview

With the rapid global adoption of EVs, charging infrastructure is experiencing massive construction demand. As a leading local EV charging network solution provider in Thailand, the customer needed to deploy hundreds of charging stations across complex and diverse environments. By adopting the Wavetel WR578, they achieved highly reliable network connectivity and intelligent wireless device management, fully ensuring stable and efficient operation of their charging stations.

Challenges

Standard networking equipment cannot withstand the high temperatures, electromagnetic interference, and strong vibrations inside charging piles, and stations must endure extreme outdoor temperatures.

Dense urban areas with peak-hour congestion require 5G high-speed connectivity to handle high transaction volumes.

When multiple station chargers malfunction, timely response is difficult, affecting user access and satisfaction.

Payments depend on low-latency, uninterrupted connectivity — any network interruption will result in user complaints.

Transaction payments and critical operational data must be protected from leakage when transmitted over public cellular networks.

Solution

Ruggedized Design

The WR578 features rugged aluminium housing with an operating temperature range of 40°C to +75°C, withstanding harsh outdoor conditions.

5G Connectivity

Supports both 4G and 5G network modes. 4G connectivity is sufficient for most charging stations under normal conditions, while 5G provides high-speed transmission during peak congestion periods.

PoE Power Delivery

All interfaces support PoE power delivery, enabling a single device to connect and power multiple peripherals simultaneously — reducing hardware footprint and deployment costs.

Dual-SIM Failover

The dual-SIM failover feature switches to a backup SIM card on another network within seconds, ensuring uninterrupted payment processing and station monitoring without service gaps.

VPN Security

Supports IPsec, OpenVPN, WireGuard, and other VPN protocols, ensuring all transaction data traverses encrypted tunnels for maximum security.

RMS

Wavetel RMS enables remote configuration, status monitoring, and firmware upgrades for routers, eliminating the need for on-site maintenance visits.
