MaxLinear, Inc. and Comtrend have announced the availability of ITU-T standards-based powerline data modules designed for backend communication in electric vehicle (EV) charging stations and supply equipment (EVSE) and smart parking infrastructure.
Built on MaxLinear’s G.hn data-over-powerline technology, Comtrend’s PM1540 module enables data transmission from power meters and Internet of Things (IoT) devices in EVSE systems over existing electrical wiring. This avoids the need for new cable installations and is particularly useful in concrete or underground environments where wireless reliability is limited.
The PM 1540 module supports up to 250 nodes per power domain, enabling large-scale deployment across EVSE infrastructure. Its G.hn-based wired communication offers a real-time, secure alternative to Ethernet or wireless in underground or concrete environments, where charging stations are often installed.
The Comtrend PM 1540 module supports:
- Data transmission using existing electrical wiring
- Real-time connectivity with low latency and consistent performance
- Integration across networks of up to 250 nodes
- Signal reach of up to 700 meters with multi-level signal repetition
This approach may offer infrastructure simplification and alternative connectivity where LAN, Wi-Fi, or cellular signals are less effective.
For additional details, Comtrend provides a product overview video and technical datasheet.
