Six Products. One Ecosystem.
Every product is designed, developed, and manufactured in-house at EarthtronEV's Alwar R&D facility. Available for technology transfer to OEMs, startups, and EV manufacturers.
EV Charger Controller
The brain of every EarthtronEV charger — a dedicated embedded controller managing power delivery, safety, communication, and user authentication in real time.
- OCPP 1.6 & 2.0 stack — built-in
- 4G / Wi-Fi / LAN / Ethernet connectivity
- RFID, QR, and app authentication
- OTA firmware update support
- Supports AC 3.3kW–22kW & DC 40kW–480kW
Dedicated Firmware
Proprietary firmware developed entirely in-house — covering power management, communication protocols, safety interlocks, metering, and cloud connectivity.
- C / C++ on RTOS (FreeRTOS / Zephyr)
- Modbus, CAN bus, RS-485 support
- MQTT / WebSocket cloud integration
- Secure boot & encrypted OTA updates
- Technology transfer — full source code
PLC — Programmable Logic Controller
Industrial-grade PLC designed for EV charging infrastructure — managing multi-charger load balancing, grid protection, and automated fault response.
- IEC 61131-3 compliant programming
- Multi-charger load management logic
- Grid protection & demand response
- DIN rail mountable — IP65 rated
- SCADA / HMI integration ready
IMD — Insulation Monitoring Device
A safety-critical device that continuously monitors insulation resistance in EV charging systems — detecting ground faults before they become dangerous failures.
- Continuous insulation resistance monitoring
- IEC 61557-8 / DIN VDE 0413 compliant
- Alarm output — relay + digital signal
- Works on AC, DC, and mixed systems
- Integrates with charger controller via CAN
EV Health Monitoring Device
A dedicated IoT device that monitors the health of EV batteries, charging systems, and vehicle electronics — providing real-time diagnostics and predictive maintenance alerts.
- Battery SoH, SoC, temperature monitoring
- Cell-level voltage & current tracking
- OBD-II / CAN bus vehicle integration
- Cloud dashboard with predictive alerts
- Fleet-wide health reporting via CSMS
EV Simulator — Car Testing Platform
A hardware-in-the-loop EV simulator for testing chargers, controllers, and firmware without a real vehicle. Simulates any EV's charging behaviour, battery profile, and communication protocol.
- Simulates AC & DC charging sessions
- Configurable battery profiles — any EV model
- ISO 15118 / CHAdeMO / CCS2 protocol support
- Fault injection — test safety responses
- Automated test scripts — CI/CD integration
