The global EVSE (Electric Vehicle Supply Equipment) market is transitioning from "coverage-based" to "efficiency-based" infrastructure. Level 2 AC charging (7kW-22kW) remains the backbone of the industry, accounting for 70% of total worldwide installations due to its balance between installation cost and battery health preservation.
As the "World's Factory," China-based Level 2 charger factories like Tongxing have integrated the entire supply chain—from power module semiconductors to smart IoT firmware. This allows for a 30-40% cost reduction compared to Western counterparts without compromising on IEC/SAE safety standards.
Modern factories are no longer just making hardware; they are building "Energy Nodes." The integration of Load Balancing and V2G (Vehicle-to-Grid) capabilities is the new frontier, allowing Level 2 chargers to stabilize local grids during peak hours.
With 23 years of expertise, Tongxing is a leader in R&D and global distribution of EV charging systems. Our portfolio ranges from 3.5KW residential wallboxes to 960KW ultra-fast stations, integrated with PV and Energy Storage.
18 automated lines with 95% automation rate and IoT-enabled quality control systems.
20+ specialists in power electronics and embedded systems, focusing on circuit topology optimization.
OCPP 1.6J/2.0.1 protocol development and cloud-based energy dispatch algorithms.
In-house EMI/EMC labs ensuring global compliance with CE, TUV, and UL requirements.
Comprehensive OEM/ODM services for global B2B clients and infrastructure developers.
The "Full-Scenario Energy Ecosystem" is the definitive solution for carbon neutrality.
By integrating rooftop PV (50-500kW) with energy storage systems (100kWh+), factories can reduce peak grid dependence by 30-50%.
| Indicator | Traditional | Integrated |
|---|---|---|
| Self-Consumption | 50% | 85%+ |
| Electricity Cost | $0.85/kWh | $0.62/kWh |
| Carbon Reduction | - | 40-60% |
Smart Home Energy Centers: 7kW/11kW Level 2 chargers synced with home batteries. Scheduled charging during off-peak hours can save up to $5,000 annually.
High-duty cycle charging for electric vans. Modular designs support wall-mounted or pedestal installs in dense urban logistics parks.
For rural areas or scenic spots, we offer containerized solar + storage + DC fast charger setups that operate independently of the main grid.
1. Bi-directional Charging (V2X): Enabling EVs to serve as mobile power banks for homes and businesses.
2. AI Predictive Maintenance: Using machine learning to detect component degradation before failure occurs, ensuring 99.9% uptime.
3. 800V Architecture: Transitioning from standard Level 2 to high-voltage AC/DC hybrid systems to support next-gen high-performance EV batteries.
Level 1 uses a standard 120V outlet (US) taking 20-40 hours for a full charge. Level 2 uses 208-240V and can charge a vehicle in 4-8 hours, making it the standard for residential and commercial use.
Top-tier factories like Tongxing follow ISO 9001 audits and obtain international certifications such as CE (Europe), TUV, and UL (North America), using military-grade components for extreme weather resistance (-35°C to 75°C).
Yes, through an Energy Management System (EMS), Level 2 chargers can prioritize solar energy, reducing grid costs and achieving a carbon-neutral footprint.
OCPP (Open Charge Point Protocol) allows chargers to communicate with different management software. Version 1.6J or 2.0.1 is essential for payment processing, remote monitoring, and smart load management.
