Dianniu GB Standard AC Charging Pile – Basic

Product Overview

The Dianniu Series GB Standard AC Charging Pile — Basic Version is ChuangRui’s commercial-grade wallbox for the Chinese market, engineered around the GB/T 20234 AC charging interface. The Dianniu line is our durable, high-utilisation platform for enterprise, real-estate and fleet deployments where hardware is expected to survive years of constant daily use. Three model variants cover both single-phase and three-phase supply: C3-02-G01-Z32-S (7kW, 32A), C3-02-G03-Z16-S (11kW, 16A) and C3-02-G03-Z32-S (21kW, 32A).

This basic version uses RFID card-swipe authentication only, with no app and no network dependency, which makes it the simplest and most cost-effective Dianniu configuration to deploy at scale. Housed in a Magic Night Black enclosure measuring 360 × 203 × 100 mm, it mounts on either walls or pillars and suits staff car parks, residential estates and fleet depots that need reliable, controlled-access charging without connectivity overhead.

Key Features & Advantages

1. Three Power Configurations, Single- and Three-Phase

The basic Dianniu range spans 7kW on single-phase 220V AC (32A) and both 11kW and 21kW on three-phase 380V AC. Buyers can standardise on one enclosure family while matching power to each site, from light residential charging to higher-throughput commercial bays.

2. RFID Card-Swipe Access Control

Charging is started and stopped by swiping an RFID card — an access method that needs no internet connection, no mobile app and no subscription service. This is the preferred configuration where a site owner simply wants to restrict charging to authorised users and keep administration offline.

3. Commercial-Durable Dianniu Construction

The Magic Night Black enclosure is IP55 rated and operates from -30°C to +50°C. The 360 × 203 × 100 mm body and the standard 5m GB-standard cable are built for continuous, heavy-duty use rather than occasional home charging.

4. Eight-Layer Electrical Safety Design

Every unit integrates leakage, overvoltage, undervoltage, overcurrent, grounding, overtemperature, emergency-stop and short-circuit protection. These protections are designed into our own control board rather than sourced as a black-box module.

5. In-House PCB and IATF 16949 Factory

The Dianniu’s control electronics are built on ChuangRui-designed PCBs manufactured in our IATF 16949-certified Wenzhou factory. Vertical integration gives buyers consistent quality and direct engineering support for custom projects. Learn more in Why In-House PCB Design Matters for EV Charger Quality & Reliability.

Application Scenarios

Enterprise and Staff Parking

Companies adding employee charging can deploy the basic Dianniu with RFID control so only authorised staff can draw power, without the cost of a networked management platform.

Residential Estates and Apartment Car Parks

Property managers issue RFID cards to residents and the pile authenticates each session offline. The three-phase 21kW model serves shared bays where faster turnaround matters.

Fleet Depots and Distribution Centres

Logistics operators charging vans and light trucks benefit from the Dianniu’s IP55 rating, wide temperature range and 21kW three-phase option, which keep vehicles moving through the day.

Frequently Asked Questions

Q: How does the basic version differ from the standard and 4G versions? A: The basic version authenticates by RFID card only. The standard version adds a WeChat Mini Program over Bluetooth for plug-and-charge, RFID and scheduled reservation charging, while the 4G version adds mobile-network connectivity for remote access.

Q: Can I mix single-phase and three-phase units in one project? A: Yes. The C3-02-G01-Z32-S runs on single-phase 220V, while the C3-02-G03-Z16-S and C3-02-G03-Z32-S run on three-phase 380V, so a single site can combine both where the electrical supply allows.

Q: What is the minimum order quantity and lead time? A: MOQ is 50 units for branded ChuangRui products and 100 units for OEM/private-label orders. Standard lead time is 30–45 days depending on order size and configuration.

Q: What warranty is provided? A: All Dianniu charging piles carry a 24-month manufacturer warranty covering defects in materials and workmanship. For related quality standards, see Why IATF 16949 Matters for EV Charging Equipment.
