As the global electric vehicle (EV) adoption rate accelerates, the residential charging landscape is undergoing a significant transformation. Traditionally, "Home Charging" was synonymous with AC slow charging (7kW-11kW). However, as modern EVs feature battery capacities exceeding 100kWh, the limitations of AC charging—primarily the constraint of the vehicle's On-Board Charger (OBC)—have become apparent. Home DC Fast Chargers (ranging from 20kW to 40kW) are emerging as the preferred solution for high-end residential projects and fleet-at-home deployments.
Unlike AC chargers, Home DC chargers convert power externally, feeding energy directly to the battery. This allows users to bypass the 7kW or 11kW limit found on most vehicle internal chargers.
Our units are designed for diverse electrical environments, supporting 380V-480V input and delivering stabilized DC output, ensuring efficiency regardless of local grid fluctuations.
Residential properties equipped with DC fast charging infrastructure see an average of 3-5% increase in valuation, catering to the growing demographic of EV owners.
Equipped with 18 automated assembly lines and IoT-enabled quality control, achieving a 95% automation rate for consistent precision.
140+ certified engineers and 20+ specialists in power electronics focused on circuit topology and energy dispatch algorithms.
