Question 1

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

Accepted Answer

A DC (Direct Current) 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 (Level 2 / AC charging piles) typically deliver up to a few kW to tens of kW, while DC fast chargers commonly range from 30 kW to 360 kW (and higher in some configurations).

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 (dual connector) and split-type / group-charging architectures are available on selected models to share power dynamically between connectors. Final available ratings depend on the specific model and project configuration.

Question 3

How long does it take to charge an EV with a DC fast charger?

Accepted Answer

Charging time depends on charger power, vehicle battery capacity, the vehicle's maximum DC charging acceptance rate, state of charge (SoC), battery temperature, and environmental conditions. As a general reference only: a 120 kW DC fast charger can add a meaningful driving range (often tens of kilometers/miles) in about 15-30 minutes for many compatible EVs. Buyers should treat published "full charge in X minutes" claims cautiously and evaluate based on real vehicle + charger pairing.

Question 4

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

Accepted Answer

We configure connectors according to the destination market and customer requirement. Commonly supported connector / plug systems include CCS1 (North America), CCS2 (Europe), CHAdeMO (Japan / legacy), GB/T (China), and NACS / SAE J3400 (North America, growing adoption). We can advise the appropriate connector combination for your market during quotation.

Question 5

Is OCPP supported? Can the chargers be managed remotely?

Accepted Answer

Yes. Our DC fast chargers support OCPP (Open Charge Point Protocol, commonly OCPP 1.6 JSON over 4G / Ethernet, with OCPP 2.0.1 available on selected models / upon request) for remote monitoring, start/stop, metering, fault diagnosis, firmware upgrade (FOTA) and reporting through a back-end charging management system (CMS). We can integrate with a third-party CMS or provide our own platform depending on the project.

Question 6

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 and any additional backend setup.

Question 7

What certifications and compliance do your chargers meet for export?

Accepted Answer

We provide certifications and test reports according to the target market. Typical certifications/compliance include CE (EU), UKCA (UK), TUV / DEKRA test reports (EU, upon request), UL / cUL or ETL (North America, model / component dependent), FCC (USA, EMC), KC (South Korea), PSE (Japan, applicable scope), SASO (Saudi Arabia) and SONCAP / other regional approvals where applicable. Exact certificates vary by model; please request the certification matrix for the specific model you intend to pu

Question 8

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. Selected models / gun holders may offer higher ratings. Please confirm the exact IP rating on the model datasheet.

Question 9

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

Accepted Answer

What are the site and electrical requirements for installing a DC fast charger?
A: A DC fast charger requires adequate three-phase grid connection capacity, a suitable distribution transformer / switchgear, proper earthing (grounding), and a qualified electrical contractor for installation. Typical considerations include available grid voltage and capacity, cable sizing, main breaker / protection, metering, network connectivity (4G / Ethernet / Wi-Fi as applicable), and local permitting.

Question 10

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

Accepted Answer

We supply complete documentation (installation manual, electrical diagram, user manual, commissioning checklist) 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, commercial terms and destination country. On-site service is quoted separately and arranged during the project contract stage.

Question 11

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. Customization feasibility and cost depend on model and order quantity.

Question 12

What is the MOQ, production capacity and delivery lead time?

Accepted Answer

MOQ and lead time are negotiable by model and configuration. As a factory reference: standard models typically ship in approximately 3-5 weeks after deposit and engineering confirmation; deeply customized OEM / ODM orders may require 5-8 weeks or more. Monthly production capacity is sufficient for both volume distribution and project orders. Please confirm the exact schedule with your sales representative based on the required model and quantity.

Question 13

What is the warranty period and after-sales policy?

Accepted Answer

We provide a standard factory warranty (commonly 2 years, extendable to 3-5 years on selected models / project basis) covering manufacturing defects and key components, subject to the sales contract. Our after-sales service includes remote technical support, fault diagnosis, spare parts supply, firmware upgrade support, and repair / replacement guidance. Warranty terms, exclusions, and extended warranty pricing should be confirmed in the proforma invoice / contract.

Question 14

How are spare parts and technical support handled after delivery?

Accepted Answer

We maintain a spare-parts list for each model (power modules, control boards, contactors, connectors, cables, displays, etc.) 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 (where applicable). For major projects, we recommend stocking a small set of recommended spare parts on site.

Question 15

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 / wiring diagram, OCPP / CMS integration guide (if applicable), certificate copies / test reports, packing list, and commercial invoice / packing documents. Documentation language can be provided in English (other languages upon request).
