In the global EV ecosystem, the 22kW AC charger (Three-Phase, 32A) has emerged as the most efficient balance between installation cost and charging speed. Unlike standard 7kW single-phase units, 22kW chargers significantly reduce dwell time for compatible vehicles, making them ideal for workplaces, retail destinations, and fleet depots.
Modern 22kW charging factories are shifting toward "Energy-Aware" hardware. Through ISO 15118 compliance, chargers are no longer passive plugs but active participants in the grid, supporting bidirectional power flow and dynamic load balancing to prevent grid overloads during peak periods.
Our R&D roadmap focuses on AI algorithms that predict user behavior. By analyzing state-of-charge (SoC) and grid pricing in real-time, our 22kW stations optimize charging schedules to ensure lowest cost per kWh for the end user.
As a certified national high-tech enterprise, Tongxing specializes in R&D and global distribution of systems ranging from 3.5KW to industrial-grade 960KW ultra-fast stations.
72,000m² intelligent production base with 18 automated lines. We achieve a 95% automation rate through IoT-enabled quality control.
