The manufacturer you choose shapes the cost, reliability and lifespan of your entire charging project. Use these criteria to choose well.

1. Real manufacturing, not just trading

Prefer a genuine manufacturer with in-house R&D and production over a reseller. It means better quality control, faster customization and direct technical support. DHES owns the full chain — R&D, manufacturing and EPC.

2. A complete product range

A single supplier that covers AC wallboxes through high-power DC stations simplifies procurement and keeps your sites consistent. DHES spans 6 kW to 480 kW.

3. Certifications for your market

Confirm the products carry the right approvals — CE, GB/T, SAE J1772, TELEC/PSE/JATE — for the regions you serve. Export-ready certification avoids costly delays.

4. Standards and connectivity

Look for OCPP networking and support for the connectors your market uses (Type 2, GB/T, CCS2, CHAdeMO), so your chargers integrate with any platform.

5. After-sales and longevity

Choose a partner with 10+ years of stability, remote diagnostics and responsive service — one that will still be here for spare parts and firmware years from now.

Score each supplier against these five points and the right partner becomes clear. At DHES, we're built to meet all five — powering every charge, empowering every future.
