Choosing an EV charger supplier is not a purchasing decision. It is a five-to-ten-year operational commitment.

The charger you buy today will be in the ground, processing payments, and interacting with vehicles until at least 2030. If the supplier disappears, stops updating firmware, or never had real engineering behind them, that charger becomes your problem — not theirs.

This checklist covers what to verify before signing a purchase order.

1. Engineering: Can They Build It?

Most suppliers have a website. Fewer have a factory. The difference shows up in delivery timelines, quality consistency, and what happens when you need something that is not in the catalog.

What to verify:

• Who owns the factory? Self-operated or contract manufacturing? Contract manufacturers optimize for their margins, not your quality.

• What is the R&D team size? 100+ engineers means firmware updates, custom integrations, and new product development continue after your order ships.

• Modular architecture? A modular DC charger lets you upgrade power without replacing the entire unit. Non-modular designs lock you into today’s specs.

• Efficiency numbers backed by test reports. 96% peak efficiency is not a marketing claim — ask for the test data.

Red flags:

• “We can build anything.” Translation: we copy reference designs and have no real engineering depth.

• No firmware update history. If you can’t see a changelog, they are not updating anything.

• “Our partner factory handles production.” Translation: we are a trading company.

2. Certifications: Is It Legal Where You Need It?

Certifications are not optional. Without the right certifications, your chargers cannot be connected to the grid, insured, or operated legally in your target market.

Core certifications by market:

What to verify:

• Certificates are current and issued by accredited bodies (TÜV Rheinland, TÜV SÜD, DEKRA, SGS, Intertek).

• The certificate covers the exact model you are buying — not a similar model from the same series.

• Compliance is not self-declared. “Self-declared CE” is not the same as third-party tested CE.

Anari Energy chargers carry CE certification from TÜV SÜD and CB scheme certification. Certificates are available for review before purchase.

3. Production Capacity: Will They Deliver?

A supplier that takes your order and delivers three months late has cost you an entire quarter of charging revenue.

What to verify:

• Factory floor space and production line automation level. 20,000m² with automated lines is a different capability than 2,000m² with manual assembly.

• Standard production cycle. Industry average for DC chargers is 45 working days. Faster is better, but only if quality does not suffer.

• Delivery cycle including testing and shipping. Total time from order to arrival at your site.

• Capacity buffer. If they are running at 95% capacity, your order competes with everyone else’s. If they are at 70%, you get priority treatment.

4. Support: What Happens After Installation?

Hardware fails. Software needs updating. Standards change. The supplier who treats the sale as the end of the relationship is not a supplier — they are a one-time vendor.

What to verify:

• Remote diagnostics capability. Can they see what is wrong before dispatching a technician?

• Spare parts availability. Are critical spares pre-positioned in your region or shipped from the factory on demand?

• Replace-before-repair policy. When a module fails, do they ship a replacement immediately or wait for the broken unit to be returned first?

• Firmware update policy. How often? Over-the-air or on-site? Is there a changelog?

• Support coverage hours and languages. If your chargers run 24/7 in Uzbekistan, you need support that works on Uzbekistan time.

One test to run: Send a technical question at an inconvenient time. See how fast you get a substantive answer. That response time is what your maintenance team will experience when a charger goes down at 10pm on a Saturday.

5. Commercial Terms: The Fine Print Matters

6. The Final Filter

After engineering, certifications, capacity, support, and commercial terms, ask one more question:

“Do they sell chargers, or do they build charging infrastructure?”

Companies in the first category disappear when the market shifts. Companies in the second category have an 80% customer re-purchase rate — because their customers keep growing and they grow with them.
