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 market during quotation.

Question 4

Is OCPP supported? Can the chargers be managed remotely?

Accepted Answer

Yes. Our DC fast chargers support OCPP 1.6 JSON over 4G / Ethernet, with OCPP 2.0.1 available on selected models. This enables remote monitoring, start/stop, metering, fault diagnosis, and firmware upgrades through a back-end charging management system.

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 to confirm model-level support.

Question 6

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

Accepted Answer

Yes. Our DC fast chargers are designed for outdoor commercial installation, typically with IP54 (or higher) ingress protection for the cabinet, providing adequate protection against dust, rain, and splashing water.

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, a suitable distribution transformer, proper earthing, and a qualified electrical contractor. Typical considerations include grid voltage (commonly 400 V / 480 V), 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 a local qualified installer, subject to project scope and commercial terms.

Question 9

Do you accept OEM / ODM customization?

Accepted Answer

Yes. We support OEM / ODM customization including enclosure color and logo, branding, connector type, cable length, power module configuration, HMI language, and payment modules.

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 details should I include when requesting a quotation?

Accepted Answer

Please share RFI information including site requirements, power needs, connector preferences, and target market. The more details you provide, the more tailored our proposal will be.

Question 12

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 13

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 14

Are your DC fast chargers suitable for outdoor public use?

Accepted Answer

Yes. They are designed for outdoor commercial / public installation with typical IP54 (model-dependent) protection and robust enclosures.

Question 15

Can one charger support two vehicles at the same time?

Accepted Answer

Dual-gun models are available, with either independent output per gun or dynamic power sharing between guns, depending on the selected model.
