Ofeixin's O2072PM/O2072PB solution is a representative example of this trend—delivering high-speed Wi-Fi connectivity and precise Bluetooth perception simultaneously on a single module, providing intelligent cockpits with an integrated "one network, multiple capabilities" solution.
In the industrial landscape of intelligent connected vehicles, charging infrastructure is an indispensable component. And PLC (Power Line Communication) technology is emerging as the core solution for electric vehicle charging pile communication.
EU regulations are mandating a comprehensive upgrade of charging pile communication methods. Under EU Delegated Regulation (EU) 2025/656, which sets a mandatory compliance deadline of 2027, developing next-generation smart AC charging piles that comply with EN ISO 15118-20:2022 has become the only path for products to enter the European market. This means the traditional PWM communication method will be phased out, with a complete transition to high-layer communication based on GreenPHY Power Line Communication (PLC), with mandatory integration of Plug & Charge (PnC) and Vehicle-to-Grid (V2G) capabilities.
The global Power Line Communication (PLC) market is projected to grow from $12.74 billion in 2025 to $14.29 billion in 2026 at a CAGR of 12.1%.
