Wallbox Charger Control Board
Product Features
EV Charging Communication
The Wallbox Charger Control Board handles Control Pilot (CP) and Proximity Pilot (PP) signals to detect vehicle connection, communicate available charging current, and manage the charging sequence.
Contactor and Power Path Control
Controls relays or contactors according to charging status, ensuring that mains power is supplied only after the required connection and safety conditions are confirmed.
Electrical Safety Supervision
Can interface with residual-current detection, temperature sensors, grounding detection, and over-current protection circuits to identify unsafe charging conditions.
Metering and Connectivity
Supports energy-metering circuits and communication options such as Wi-Fi, Bluetooth, Ethernet, RS485, or 4G for consumption records, remote access, and charger management.

Product Advantages
Controlled Charging Sequence
The board manages each stage from plug detection and vehicle handshake to power activation and charging termination, reducing the risk of uncontrolled energization.
Suitable for Smart Wallboxes
Network connectivity enables functions such as scheduled charging, user authentication, energy records, remote status checking, and load management.
Supports Different Charging Ratings
The Wallbox Charger Control Board can be developed for single-phase or three-phase AC chargers with different current and power configurations.
Ready for Backend Integration
Depending on the product architecture, communication functions can support connection with charging management platforms and protocols such as OCPP.
Manufacturing Process
Production includes multilayer PCB fabrication, SMT assembly, relay and connector mounting, firmware programming, and electrical verification. CP/PP signal behavior, contactor outputs, metering circuits, communication ports, and protection inputs are checked during functional testing. High-voltage and low-voltage areas receive particular attention during assembly and inspection.
Services
We support Wallbox Charger Control Board projects from prototype PCBA builds to scheduled volume production. Manufacturing services can include BOM procurement, DFM review, SMT/THT assembly, firmware flashing, conformal coating, functional test fixture development, cable assembly, and complete charger electronics integration according to customer production files.
