Leading the Charge in Electric Mobility Infrastructure
As a leading China Electric Car Charger 7kw Manufacturer, we understand that the 7kW AC charger represents the "Golden Ratio" of residential and workplace charging. It balances grid load, installation cost, and vehicle replenishment speed, providing roughly 25-30 miles of range per hour of charging—perfect for overnight or office-day cycles.
Our 7kW units utilize the latest Silicon Carbide (SiC) power modules and Dynamic Load Balancing (DLB) technologies to ensure 99% uptime and grid stability.
Fully compliant with IEC 61851 and ISO 15118 protocols. Featuring Type B RCD, over-voltage, and flame-retardant (UL94-V0) materials.
Integrated with OCPP 1.6J/2.0.1 for seamless cloud management, RFID/APP authorization, and remote OTA firmware updates.
Investing heavily in V2G (Vehicle-to-Grid) and V2H (Vehicle-to-Home) capabilities to transform EVs into mobile energy storage assets.

Photovoltaic-Energy Storage-EV Charging Integration
| PV Self-Consumption Rate | ↑ 70% (Industry avg 50% → 85%+) |
| Comp. Electricity Cost | ↓ 27% ($0.85 → $0.62 /kWh) |
| Carbon Reduction | 40%-60% Annual decrease |
Most residential electrical panels are limited. A 7kW charger (32A single-phase) is often the maximum a standard house can support without expensive grid upgrades, while still providing a full charge overnight.
Yes, our chargers are compatible with all major EV brands (Tesla, BYD, Volkswagen, Hyundai, etc.) using Type 1 (SAE J1772) or Type 2 (IEC 62196-2) connectors.
For standard 7kW units, our lead time is 7-14 working days. Custom OEM orders with specific branding usually take 21-30 days depending on component customization.
OCPP (Open Charge Point Protocol) allows your chargers to communicate with any management software. This means you aren't locked into one provider and can easily manage billing, power limits, and diagnostics.
