EV Charger Controller — The Core of Your Next Charger
Tech OVN's EV charger controller is an OEM board for AC charger makers that combines relay control, electrical protection, Class 1 energy metering, WiFi, Ethernet, RS485 and OCPP 1.6J / 2.0.1 on one board, with development kits and integration documentation.
Trusted by energy & industrial leaders
The metering board is the differentiator
You're buying our metering board to put inside your enclosure. The reason it matters: the same engineers who design Tech OVN's utility smart meters design this board. Most OEM controller boards use a third-party metering module that drifts in the field. Ours doesn't — your chargers stay revenue-accurate across their service life, so the billing data your CPO platform reads in year five is the same data it read in year one.
One Board. The Whole Charger.
Tech OVN's EV Charger Controller is a complete electronics platform for companies building their own AC EV chargers. It integrates everything you need in one board: relay control, electrical protection, Class 1 energy metering, WiFi, Ethernet and RS485 connectivity, and OCPP support. With our experience in IoT and energy measurement, we give charger manufacturers a head start — skip the electronics development and focus on your enclosure design, brand, and sales.
Key Features
Everything a charger needs — engineered, tested, and ready to drop into your enclosure.
Compact, All-In-One Design
Relay, protection circuits, energy meter, and communication module on a single board. Reduces your BOM and assembly complexity.
Built-In Smart Meter
Class 1 energy metering with sustained long-term accuracy. Accurate billing from day one.
Flexible Communication
WiFi and Ethernet direct to your OCPP server, plus RS485 (Modbus RTU) for multi-charger sites behind a single uplink.
OCPP 1.6J & 2.0.1
Works with any CPO platform that supports OCPP 1.6J or 2.0.1. We help with OCPP integration and can adapt firmware for bulk orders.
Comprehensive Safety
Overcurrent, over/under voltage, ground fault detection, surge protection. Designed to IEC 61851-1.
Modular & Customisable
Adaptable to different enclosure designs and power ratings. Works for home chargers, commercial units, and fleet stations.
