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 to match different site requirements, typically 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 configure connectors according to the destination market. Commonly supported systems include 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 (commonly OCPP 1.6 JSON over 4G / Ethernet, with OCPP 2.0.1 available on selected models) for remote monitoring, start/stop, metering, fault diagnosis, firmware upgrade (FOTA) and reporting through a back-end charging management system.

Question 5

Is ISO 15118 or Plug & Charge supported?

Accepted Answer

ISO 15118 (including Plug & Charge / automatic authentication) is supported on selected models and firmware versions, subject to configuration and CMS capability. If Plug & Charge is a project requirement, please highlight it 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. Our DC fast chargers are designed for outdoor commercial installation, typically with IP54 (or higher, model dependent) ingress protection for the cabinet and 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

A DC fast charger requires adequate three-phase grid connection capacity, a suitable distribution transformer, proper earthing, and a qualified electrical contractor. Typical considerations include available grid voltage, cable sizing, main breaker, metering, and network connectivity.

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 / service partner, 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 and logo, branding / label, connector type and cable length, power module configuration, language of HMI / user interface, optional payment & authentication modules, and CMS / OCPP integration.

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 / remote access. For major projects, we recommend stocking a small set of recommended spare parts on site.

Question 11

What documentation is provided with the equipment?

Accepted Answer

Each shipment is accompanied by a project handover package, typically including product specification sheet, installation & commissioning manual, user operation manual, electrical schematic, OCPP / CMS integration guide, certificate copies, packing list, and commercial invoice.

Question 12

What details should I include when requesting a quotation?

Accepted Answer

To receive a fast and accurate quotation, 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 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 and 70% balance before shipment, or as negotiated. We also support Irrevocable Letter of Credit (L/C) for qualified orders.

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.
