Wholesale 32 Amp EV Charger Suppliers & Factory

Leading the Global Transition to Sustainable Mobility with High-Performance 7kW - 22kW Intelligent Charging Infrastructure

🏢

TONGXING NEW ENERGY TECHNOLOGY

As a certified national high-tech enterprise with 23 years of expertise in the energy sector, Tongxing specializes in R&D, production, and global distribution of innovative EV charging systems. Our comprehensive product portfolio spans from 3.5KW residential chargers to industrial-grade 960KW ultra-fast charging stations, complemented by integrated photovoltaic (PV) and energy storage solutions.

The 32 Amp Efficiency Benchmark

In the EV ecosystem, 32 Amp is recognized as the "Golden Standard" for AC charging. Whether it's a 7kW single-phase home setup or a 22kW three-phase commercial installation, 32A delivers the optimal balance between installation cost and charging speed, replenishing approximately 25-45 miles of range per hour of charge.

Common Questions & Expertise (FAQ)

Technical Insights for Informed Sourcing

Why choose a 32 Amp charger over a 16 Amp or 40 Amp model?
A 32 Amp charger (7.2kW) is the ideal balance for most residential and commercial electrical panels. While 16A is often too slow for modern high-capacity EV batteries, 40A or 48A chargers often require expensive panel upgrades. 32A provides "full charge" capability overnight for almost any EV on the market today.
What are the compliance requirements for importing EV chargers from China?
For European markets, CE (LVD/EMC) and RoHS certifications are mandatory. For the North American market, UL or ETL certification is required. Tongxing chargers are fully certified and compliant with IEC 61851 and SAE J1772 standards.
How does Dynamic Load Balancing (DLB) benefit my installation?
DLB monitors the total power consumption of a building in real-time. If other appliances (like AC or water heaters) are active, the charger automatically reduces its output to prevent tripping the main circuit breaker. This avoids costly infrastructure upgrades.
Can these chargers be customized with my own brand?
Yes, as a factory, we offer full OEM/ODM services including customized enclosures, cable lengths, APP interfaces, and logo silk-screening to support your brand identity.
