UltraFast EV Charger Technology: OCPP 2.0.1, ISO 15118 & Dynamic Load Sharing
Every UFC ultra-fast EV charger and DC fast charging system from the 22kW wall-mounted charger to the 400kW highway flagship runs on a common firmware platform, communication stack, and safety architecture. Engineered in Hyderabad, India, UFC charging technology combines OCPP 2.0.1, ISO 15118, dynamic load sharing, high-efficiency power conversion, and in-house engineering across the complete 22kW to 400kW range.
OCPP 1.6J and OCPP 2.0.1 for EV Fast Chargers
OCPP (Open Charge Point Protocol) is an open communication standard that enables EV fast chargers and DC charging stations to exchange data with charging station management systems (CSMS). OCPP helps charging operators monitor, manage, update, and control connected EV chargers without being locked to a single software platform.
What OCPP 1.6J Enables on UFC DC Fast Chargers
- Basic remote monitoring and real-time session management
- OTA firmware updates no technician site visit required
- RFID multi-standard authentication — Mifare, FeliCa, NFC
- Compatible with all current Indian CSMS platforms
- Charging profile management and session reservation
What OCPP 2.0.1 Adds to UFC EV Chargers
- TLS encryption and certificate-based device authentication
- Advanced smart charging profiles for grid-responsive load management
- ISO 15118 Plug and Charge and Autocharge support
- Full device management model component and variable level control
- V2G readiness for bidirectional energy flow
- Multi-session, multi-gun transaction management
- Improved cybersecurity resistant to threats on connected chargers
ISO 15118 Plug and Charge for UltraFast EV Chargers
ISO 15118 enables secure communication between an EV and a charging station and supports Plug and Charge, allowing compatible vehicles to authenticate automatically using digital certificates. UFC's charging platform supports ISO 15118 communication for simplified and secure EV charging.
EV Charger Authentication Methods
- Plug and Charge via ISO 15118 PKI - Compatible vehicles use a digital certificate for automatic authentication and session initiation.
- Autocharge — Simplified auto-start for non-PKI networks, no card or app needed
- RFID multi-standard — Mifare, FeliCa, NFC all three supported on every unit
- Mobile App and QR code — App-based or QR code session start option
Dynamic Load Sharing in DC Fast Charging
Dynamic load sharing in DC fast charging distributes available electrical power between multiple charging guns in real time according to each vehicle's charging demand. Instead of using a fixed power split, the system dynamically allocates available capacity to maximize site utilization and charging throughput.
How Dynamic Load Sharing Works on UFC240
Example — UFC240 with 120kW total available power. Vehicle A at 20% state of charge requests 100kW. Vehicle B at 70% state of charge accepts only 30kW. UFC's dynamic system allocates 100kW to Vehicle A and 30kW to Vehicle B — using available capacity efficiently based on actual demand.
Dynamic Load Sharing — Available On
- UFC240 — 60kW to 240kW commercial DC fast charger for fleet depots and urban hubs
- UFC400 — 120kW to 400kW highway flagship DC fast charger
>96% Power Conversion Efficiency Across the DC Fast Charging Range
UFC DC fast chargers deliver greater than 96% power conversion efficiency across the specified operating range, from 22kW to 400kW output.
How UFC Achieves High DC Fast Charger Efficiency
- Centrifugal thermal cooling — Active heat management at the power module level
- Thermal-path-optimised cabinet layout
- Adaptive high-current Boost Mode
- In-house thermal management R&D
OTA Firmware Updates for EV Charging Stations
UFC EV charging stations receive over-the-air (OTA) firmware updates through the OCPP connection. Operators can remotely deploy security patches, bug fixes, and new software features without requiring a technician to visit each charging site.
What OTA Firmware Enables for Charge Point Operators
- Security patches deployed across all units remotely
- Bug fixes resolved without charger downtime
- New features enabled on existing hardware
- Consistent firmware version maintained across the entire installed base
- Updates schedulable during low-utilisation periods
- Complete audit trail of all firmware versions per unit
High-Cycle Cable and Connector Engineering for DC Fast Chargers
The charging cable, gun, and connector contacts are among the highest-cycle components in a DC fast charging station. UFC's hardware engineering focuses on cable durability, connector reliability, thermal performance, and long-term operation in high-utilization charging environments.
Self-Retracting Falcon-Wing Cable Management - UFC400
Cables extend for use and retract automatically when released eliminating floor contact, dragging, and coiling that causes cable jacket wear and strain relief fatigue in high-cycle highway deployments.
Replaceable Gun Contacts — UFC400
The charging gun contacts make and break the electrical connection at every single session. UFC400's contacts can be replaced independently, without replacing the cable or gun assembly.
Anti Water-Logging Gun Holder — UFC400
Prevents rain accumulation around the connector seating area a specific failure mode in monsoon conditions.
