Commercial 40kW Wallbox DC Fast Charger OCPP 1.6J | B2B Wholesale Guide

Executive Overview

The WY02-B Series (20kW/30kW/40kW) is a compact wall-mounted DC fast charger designed for commercial fleets, parking, and workplaces. Supporting 200V-1000V DC output and multi-standard connectors (CCS1/CCS2/NACS), it seamlessly charges 400V and 800V EVs. Built with IP54/IK10 protection and OCPP 1.6J cloud connectivity, it offers a cost-effective fast-charging solution.

1. Why Small DC Wallbox Chargers Are Taking Over Commercial Charging

As EV adoption accelerates across North America and Europe, commercial property owners, fleet operators, and logistics depots face a key infrastructure challenge: AC Level 2 charging is often too slow for fleet turnaround times, while traditional 120kW+ DC fast charging cabinets require massive grid transformer upgrades and heavy capital expenditure.

The WY02-B Series Wall-Mounted DC Fast Charger fills this gap perfectly. Delivering flexible power outputs of 20kW, 30kW, and 40kW, it allows businesses to deploy rapid DC charging without incurring prohibitive grid expansion costs.

2. Key Technical Advantages for B2B Importers

Ultra-Wide Output Voltage Range: 200V to 1000V DC

Equipped with next-generation power modules, the WY02-B supports an ultra-wide output voltage range from 200V DC up to 1000V DC. This ensures 100% compatibility across both standard 400V battery architectures and modern 800V high-voltage platforms (such as Porsche Taycan, Hyundai Ioniq 5, and commercial electric vans).

Global Multi-Standard Connector Compatibility

Designed for worldwide distribution, the unit can be configured with multiple connector standards to fit regional requirements:

• CCS2: European & Australian commercial standard

• CCS1: North American standard

• NACS: North American Charging Standard (Tesla compatible)

• ChAdeMO & GBT: Asian and specialty fleet requirements

OCPP 1.6J Cloud Integration & Smart Management

Built-in Open Charge Point Protocol (OCPP 1.6J) enables seamless integration with third-party CSMS (Charging Station Management Systems). Operators can easily manage user authentication, billing, remote diagnostics, and dynamic load balancing via Ethernet, Wi-Fi, or optional 4G cellular connectivity.
