As the global transition to sustainable transportation accelerates, the EV Charge Controller has emerged as the most critical component within the charging ecosystem. Unlike simple power cables, a professional-grade charge controller manages the complex communication between the vehicle's Battery Management System (BMS) and the power grid. As a leading China EV charge controller manufacturer, TONGXING NEW ENERGY TECHNOLOGY CO., LTD. integrates 23 years of power electronic expertise to deliver solutions that prioritize safety, interoperability, and future-proof scalability.

Our factory maintains CE, TUV, UL, and GB/T compliance. We adhere to ISO 9001 and ISO 14001 standards to ensure every controller meets international safety benchmarks.
We provide localized firmware for different markets, ensuring compatibility with regional grid standards (e.g., European TN/TT systems) and language support for user interfaces.
As a Tier-1 China EV charge controller factory, we offer stable lead times and OEM/ODM services, allowing global brands to scale their infrastructure rapidly.
Q1: What is the primary role of a charge controller in an EV station?
A: The charge controller acts as the central processor. It monitors power flow, manages safety protocols (like ground fault detection), handles the handshake with the vehicle's BMS, and communicates with billing/management software via OCPP.
Q2: Why choose a China-based manufacturer for charge controllers?
A: China currently leads the world in EV deployment. Manufacturers like Tongxing benefit from a mature supply chain, rapid R&D iteration, and significant cost advantages without compromising on high-tech features like AI energy management.
Q3: Does your hardware support third-party software?
A: Yes. All our controllers are fully OCPP 1.6J compliant (upgradable to 2.0.1), meaning they can connect to any standard charging station management system (CSMS) globally.
Q4: How do you ensure product reliability in extreme climates?
A: Our controllers are tested for operations ranging from -35°C to 75°C. We use industrial-grade components and IP55/IP65 rated enclosures to protect against dust, moisture, and salt spray.
