As the global automotive landscape shifts toward electrification, the 22kW home charger has emerged as the definitive "Gold Standard" for residential and light commercial applications. At TONGXING NEW ENERGY TECHNOLOGY CO., LTD., a National High-Tech Enterprise, we don't just manufacture hardware; we engineer smart energy nodes that bridge the gap between the power grid and the electric vehicle.
With 23 years of expertise in power electronics, our R&D team has developed a 22kW solution that addresses the three primary pain points of modern EV owners: charging speed, grid stability, and smart integration. Unlike standard 7kW single-phase chargers, our 22kW three-phase systems reduce charging time by 66%, providing a full charge for most modern EVs in just 3-4 hours.
Equipped with 18 automated assembly lines and IoT-enabled quality control systems, achieving a 95% automation rate for consistent high-tier quality.
20+ specialists in power electronics and embedded systems focused on OCPP 2.0.1 protocols and thermal management optimization.
Rigorous 40-member audit team ensuring every unit meets the highest safety standards before leaving our facility.
Sourcing from a leading China 22kW home charger manufacturer like Tongxing offers more than just competitive pricing. It provides access to a "Full-Stack" development ecosystem. We ensure our products meet diverse global standards:
Our chargers are engineered with Dynamic Load Balancing (DLB), an essential feature for older residential grids that prevents home circuit overloads while prioritizing EV charging speed.
| Indicator | Traditional Solution | Tongxing 22kW Integrated Solution | Improvement |
|---|---|---|---|
| PV Self-Consumption Rate | 50% | 85%+ | ↑ 70% |
| Comprehensive Electricity Cost | 0.85 USD/kWh | 0.62 USD/kWh | ↓ 27% |
| Annual Carbon Reduction | Baseline | 40% - 60% Reduction | Significant Gain |
Rooftop solar panels provide real-time power, meeting 30%-50% of charging demand at 1/3 the grid cost.
Store low-cost power during off-peak hours and discharge during peak times, reducing electricity bills by 40%.
Supports 120kW-960kW ultra-fast stations for commercial hubs, adding 200km range in just 10 minutes.
Prioritizes PV/storage power, automatically supplementing with grid power during off-peak hours for maximum savings.
Attempts 100% renewable energy use, ideal for users pursuing a zero-carbon lifestyle and green certifications.
Automatically switches to backup battery power during grid outages, ensuring 72-hour supply for essentials.
Sleek, wall-mounted 22kW AC chargers with APP scheduling for overnight charging at the lowest rates.
Multi-unit installations with RFID payment and OCPP backend integration for office parks and shopping malls.
Heavy-duty charging piles designed for 24/7 operation with IP55 protection for truck and fleet depots.
Solar Array + Energy Storage System + DC Charger configuration for camps and scenic spots without grid access.
The industry is moving toward Vehicle-to-Grid (V2G) technology, where your EV acts as a mobile battery for the home. Our R&D is already integrating bidirectional charging capabilities into our next-gen 22kW platforms. Furthermore, with the rise of 800V vehicle architectures (like the Porsche Taycan and Hyundai IONIQ 5), our high-voltage cascaded storage technology ensures that your home or business infrastructure remains future-proof.
A true 22kW charger requires a three-phase electricity supply (32A per phase). For single-phase homes, the charger will typically operate at 7.4kW. We recommend consulting with our engineering team to evaluate your local grid capacity.
Beyond the cost-efficiency of the supply chain, Chinese manufacturers like Tongxing lead in "Integrated Solar-Storage-Charging" solutions. You receive a more mature software ecosystem (OCPP integration) and faster iteration of hardware compared to traditional regional suppliers.
Yes, our chargers use the Type 2 (IEC 62196-2) standard which is the universal standard for Europe and many other regions. It is compatible with Tesla, BYD, BMW, VW, and all other major brands. For North America, we provide Type 1 (SAE J1772) variants.
DLB monitors the real-time electricity consumption of your household appliances. If you turn on an oven or HVAC, the charger automatically reduces its power output to ensure the total load doesn't trip your main breaker.
