As the global automotive landscape pivots toward electrification, the demand for interoperable, secure, and scalable charging infrastructure has reached a critical tipping point. Wholesale OCPP-compliant charger suppliers are no longer just hardware vendors; they are the architects of the smart energy grid. Tongxing New Energy Technology Co., Ltd., a national high-tech enterprise with 23 years of energy sector heritage, stands at the forefront of this transformation.
OCPP (Open Charge Point Protocol) serves as the universal language between the Electric Vehicle Supply Equipment (EVSE) and the Charging Station Management System (CSMS). Without strict adherence to OCPP 1.6J or the advanced 2.0.1 protocols, network operators risk "vendor lock-in," a strategic bottleneck where hardware cannot be migrated to new software platforms. Our mission is to provide open-source flexibility combined with industrial-grade reliability.
While OCPP 1.6J is the current industry standard for smart charging, our R&D roadmap focuses on the implementation of OCPP 2.0.1. This transition enhances data security (TLS), improves diagnostics, and supports complex pricing structures essential for commercial fleet management.
Vehicle-to-Grid (V2G) technology transforms EVs into mobile batteries. Our future-ready chargers are designed to support bidirectional power flow, allowing businesses to discharge vehicle energy back into the grid during peak tariff hours, creating new revenue streams.
We are integrating ISO 15118 to eliminate the need for RFID cards or APPs. The charger identifies the vehicle via encrypted digital certificates, providing a seamless user experience similar to Tesla's Supercharger network across all brands.
Tongxing’s 72,000m² production base is a testament to Industry 4.0 principles. With 18 automated assembly lines and IoT-enabled quality control, we achieve a 95% automation rate, ensuring that every unit—from 3.5KW residential wallboxes to 960KW ultra-fast stations—meets stringent global standards.
Beyond hardware, we provide full-scenario energy ecosystems. Our integrated solutions reduce electricity costs by up to 27% compared to traditional charging stations.
| Indicator | Traditional Solution | Integrated (PV+Storage) | Improvement |
|---|---|---|---|
| PV Self-Consumption Rate | 50% | 85%+ | ↑ 70% |
| Comprehensive Electricity Cost | 0.85 USD/kWh | 0.62 USD/kWh | ↓ 27% |
| Annual Carbon Emission Reduction | Standard | 40% - 60% Higher | Significant |
| Grid Peak Stress | High | Low (Peak Shaving) | Stabilized |
Urban hubs requiring high turnover. Our 120kW-960kW ultra-fast chargers add 200km range in just 10 minutes, maximizing station throughput.
Reducing enterprise carbon footprints. We integrate rooftop PV with modular storage (100kWh-10MWh) to power fleet logistics cost-effectively.
Smart AC wallboxes with scheduled charging (DLB function) to utilize off-peak electricity, saving families thousands annually.
Navigating global regulations is the biggest hurdle for B2B buyers. Tongxing provides comprehensive support for CE (Europe), UL (North America), UKCA (UK), and GBT (China) standards. Our products are engineered with military-grade materials to withstand Iceland's Arctic freeze and Saudi Arabia's desert heat.
What should procurement directors look for in a Wholesale OCPP-compliant charger factory? It goes beyond the unit price. Total Cost of Ownership (TCO) is the metric that matters.
We provide full OEM/ODM services, allowing B2B clients to launch their own branded charging networks with customized casing, UI, and APP integration.
Real-time monitoring and remote firmware updates (OTA) via OCPP minimize on-site maintenance costs and improve station uptime to 99.9%.
Our Tier-1 component sourcing and massive inventory levels ensure stable lead times even during global semiconductor fluctuations.
OCPP 1.6J is JSON-based and is the most widely used version today, supporting smart charging and basic diagnostics. OCPP 2.0.1 offers significant improvements in security, device management, and support for ISO 15118 (Plug & Charge).
Yes, our AC and DC chargers include DLB functionality to protect the local grid and building electrical systems from overloading by adjusting the charging power in real-time.
Standard products typically ship within 2-4 weeks. Custom OEM projects may take 6-8 weeks depending on the complexity of the hardware and software modifications.
We offer a 24-month warranty and lifetime technical support. Our cloud platform allows for remote diagnostics, solving 90% of software issues without a site visit.
Our chargers are designed according to international standards (Type 1, Type 2, CCS1, CCS2, GBT, CHAdeMO), ensuring compatibility with Tesla, BYD, Volkswagen, BMW, and all other major EV manufacturers.
