Why Hardware Supplier Selection Is a Strategic Decision
EV charger hardware is safety-critical infrastructure. A single faulty batch can cause vehicle damage or fire, fail regulatory inspection, damage your brand reputation, and interrupt your OCPP network uptime SLAs. Your EV charging system manufacturer is a long-term technical partner.
The 7 Criteria for Evaluating an EV Charger Hardware Supplier
1. In-House R&D and Engineering Depth
A real manufacturer designs its own hardware and owns the firmware source code. Share Charging has 80+ in-house R&D engineers in hardware, firmware, and protocol development.
2. Certification Portfolio
Europe: CE, TÜV/DEKRA, OCPP compliance. USA: UL 2594, FCC. UK: UKCA, OZEV. Critical: SECC must be TÜV or DEKRA certified for ISO 15118 and DIN 70121.
3. Protocol Coverage
Verify support for ISO 15118, DIN 70121, CCS1/CCS2/CHAdeMO/GB/T, and OCPP 1.6/2.0.1.
4. Production Capacity and Quality Control
Verify annual production capacity, QC process (100% inspection vs. sampling), traceability by serial number, and typical lead time from purchase order to delivery.
5. After-Sales Support and Firmware Longevity
EV charging standards evolve rapidly. Ask: Do they offer OTA updates for deployed units? What is the firmware support period? Do they have local technical support in your region?
