Question 1

What is a DC fast charging station, and how is it different from an AC charger?

Accepted Answer

A DC fast charging station converts AC grid power to DC inside the charger and delivers DC power directly to the EV's battery, bypassing the vehicle's slower on-board AC charger. This enables much higher charging power and shorter charging times. AC chargers typically deliver up to a few kW to tens of kW, while DC fast chargers commonly range from 30 kW to 360 kW.

Question 2

What power levels / kW ratings are available?

Accepted Answer

We offer a range of DC fast charging outputs including 30 kW, 40 kW, 60 kW, 80 kW, 120 kW, 160 kW, 180 kW, 240 kW, 320 kW, and 360 kW classes. Dual-gun and split-type architectures are available on selected models to share power dynamically between connectors.

Question 3

Which connector types / plugs do you support for different markets?

Accepted Answer

We support CCS1 (North America), CCS2 (Europe), CHAdeMO (Japan), GB/T (China), and NACS / SAE J3400 (North America). We advise the appropriate connector combination for your specific market during the quotation process.

Question 4

Is OCPP supported? Can the chargers be managed remotely?

Accepted Answer

Yes. Our DC fast chargers support OCPP (commonly 1.6 JSON over 4G/Ethernet, with 2.0.1 available on request) for remote monitoring, start/stop, metering, fault diagnosis, and firmware upgrades. We can integrate with third-party CMS or provide our own platform.

Question 5

Is ISO 15118 or Plug & Charge supported?

Accepted Answer

ISO 15118 (including Plug & Charge) is supported on selected models and firmware versions, subject to configuration and CMS capability. Please highlight this requirement in your RFI so we can confirm model-level support.

Question 6

Can the chargers be installed outdoors? What is the IP rating?

Accepted Answer

Yes, they are designed for outdoor commercial installation with typical IP54 (or higher, model dependent) ingress protection against dust, rain, and splashing water. Please confirm the exact IP rating on the model datasheet.

Question 7

What are the site and electrical requirements for installing a DC fast charger?

Accepted Answer

Requirements include adequate three-phase grid connection capacity, suitable distribution transformer, proper earthing, and a qualified electrical contractor. Typical considerations include grid voltage (commonly 400V/480V), cable sizing, and network connectivity (4G/Ethernet/Wi-Fi).

Question 8

Do you provide on-site installation or remote commissioning support?

Accepted Answer

We supply complete documentation and provide remote commissioning support. For overseas projects, we can dispatch engineers or work with local partners, subject to project scope and commercial terms. On-site service is quoted separately.

Question 9

Do you accept OEM / ODM customization?

Accepted Answer

Yes. We support OEM/ODM customization including enclosure color, logo, branding, connector type, cable length, power module configuration, HMI language, and payment modules. Feasibility and cost depend on the model and order quantity.

Question 10

How are spare parts and technical support handled after delivery?

Accepted Answer

We maintain a spare-parts list for each model and can supply critical spares with the shipment or as follow-up orders. Technical support is provided by our engineering team via email, video call, or remote access.

Question 11

What documentation is provided with the equipment?

Accepted Answer

Each shipment includes a project handover package with specification sheets, installation manuals, user manuals, electrical schematics, OCPP integration guides, certificates, and commercial documents. Documentation language can be provided in English.

Question 12

What details should I include when requesting a quotation?

Accepted Answer

Please share RFI information including site requirements, desired power levels, connector types, and specific customization needs. The more details you provide, the more tailored our proposal will be.

Question 13

What Incoterms and payment terms do you accept?

Accepted Answer

We commonly quote under FOB, CIF, CFR, or EXW, with DDP/DAP available for selected destinations. Payment is typically T/T (30% deposit, 70% balance) or Irrevocable Letter of Credit (L/C).

Question 14

What is the typical order and delivery process?

Accepted Answer

The process includes: (1) Buyer submits RFI, (2) We issue quotation & PI, (3) Buyer confirms order and pays deposit, (4) Engineering confirmation & production, (5) Pre-shipment inspection, (6) Balance payment, (7) Shipping & documentation, (8) Delivery and after-sales service.

Question 15

Are your DC fast chargers suitable for outdoor public use?

Accepted Answer

Yes. They are designed for outdoor commercial/public installation with typical IP54 protection and robust enclosures.
