With more experience from municipal infrastructure and industrial projects, TFY has focused on reliable, data-driven system solutions for many years. EV charging infrastructure is growing fast. At the same time, the market now needs better fast-charging performance, accurate metering, clear data, and stable operation.
From a project view, a DC EV charging gun is not just a connector anymore. It is now a key point for metering, monitoring, and trust in the whole system.
Many traditional charging systems use centralized metering. This can cause errors and make checks harder. TFY’s DC charging gun uses a built-in metering design. It puts a high-accuracy metering module directly inside the gun body.
Key features:
Detachable metering module, so it can be calibrated and tested on its own
Anti-tamper sealed structure, so illegal actions are prevented
Measurement accuracy meets relevant standards
With this design, each charging gun becomes an independent and trusted metering unit. This improves billing accuracy and helps meet compliance needs.
In modern charging networks, data integrity and traceability matter to both operators and regulators. TFY improves data reliability in these ways:
Encrypted data transmission from the charging gun, so the data source is secure and trusted
Dual-channel checks, so charging data is compared and cross-checked in real time
Data consistency reaches 99.8%, which supports accurate billing and audits
Also, each charging gun supports full lifecycle traceability:
Performance checks before operation
Initial calibration before going online
Continuous online monitoring during use
Fast response when problems happen
This builds a clear system that can be traced, checked, and seen from start to end.
In high-use charging sites, operating efficiency is a main concern. TFY’s DC charging gun is designed to reduce downtime and make maintenance simple.
Fast replacement, continuous operation
Replacement takes about 30 minutes
Backup units support fault replacement in minutes
Site operation is affected very little
Smart monitoring, real-time alerts
The system keeps monitoring many items:
Voltage, current, power, and energy
Real-time status tracking
Automatic alarms when limits are exceeded
Abnormal events are handled within 24 hours, so system response and stability improve.
The charging gun supports:
Fast connection to existing charging systems
Pre-installed setup for new projects
Standard installation and network access
So it fits many sites and many system types.
Based on TFY’s engineering and project experience, the value shows in several areas:
For regulators
Testing efficiency improves by 8–10×
Verification cost drops by more than 85%
Supports remote supervision with gun-level data
For charging operators
Downtime drops from days to minutes
Data is clear and reliable, so user trust improves
Supports modular, standard, and smart upgrades
Cost optimization
| Cost item | Traditional solution | TFY solution |
| Calibration cost | High (by system) | Lower (by gun) |
| Labor cost | High | About 40% lower |
| Transport and equipment | High | About 35% lower |
| Long-term cost | Large changes | More predictable |
Safety and data trust
Encrypted transmission + anti-tamper sealing helps stop cheating
Dual-channel checks help keep metering accurate
Reliable data improves user confidence and public trust in the system
As charging infrastructure upgrades, the charging gun is changing from a simple interface to a core part for metering, data integrity, and operating efficiency. TFY’s DC charging gun uses built-in metering, a secure data design, and full lifecycle traceability to support modern fast-charging systems. It improves charging reliability and maintenance efficiency. It also supports trusted data, compliant operation, and long-term system performance.
