Critical Parameters for Procurement
Power and Current Curve: Check available output power across the supported voltage range. Rated power and maximum current may not be available simultaneously under all operating conditions.
Simultaneous Charging: Request the power allocation matrix for two or more connected vehicles. Confirm the available power per outlet under concurrent charging.
Grid Connection: Verify input current, transformer capacity, upstream protection, power factor, harmonic performance, and local utility requirements.
Thermal Performance: Review continuous output and derating limits at the expected site ambient temperature.
Installation Requirements: Confirm dimensions, foundation or mounting details, cable reach, maintenance clearance, ventilation, and service access.
Vehicle Compatibility and System Integration
Connector and Vehicle Compatibility
Connector availability depends on the selected charger model, regional configuration, and applicable requirements. Confirm connector type, voltage and current limits, charging communication, and compatibility with the target vehicle fleet.
Charging Management and Network Integration
OCPP Connectivity: Confirm whether the selected model supports OCPP 1.6J or OCPP 2.0.1, including the functions required by the intended charging management system. These versions are not backward-compatible, so compatibility must be checked rather than assumed.
Dynamic Load Management: Where supported, charging power can be managed against configured site limits. Confirm whether control is integrated into the charger, supplied by an external energy management system, or provided through the backend.
Energy Storage and Solar Integration: Confirm the required control interfaces, system architecture, and power management responsibilities before specifying integration with battery energy storage or photovoltaic systems.
Payment and User Authentication: Verify the availability of payment terminals, RFID, QR code, or other authentication options for the target market and operating model.
Quality Control and Factory Testing
Factory inspection and test procedures should be defined for the selected model and purchase specification.
Electrical and Functional Testing
Electrical Safety: Verify that applicable insulation, grounding, protection, and emergency-stop tests are included in the approved inspection plan.
Power Performance: Confirm the scope of rated-load testing, output measurement, and thermal performance verification.
Communication and Software: Check firmware version, communication functions, charging-session logic, and required backend integration tests.
Enclosure and Environmental Protection: Review the supporting evidence for IP/IK ratings and any specified environmental or corrosion-resistance tests.
Quality Documentation
The documentation package can be defined during order confirmation and may include the following items where applicable:
Factory Test Records: Model-specific functional, electrical, and output test reports.
Compliance Documents: Applicable certificates, declarations, and test reports for the selected model and destination market.
Configuration Records: Approved product specification, firmware version, connector configuration, and serial-number records.
Technical Manuals: Installation, operation, maintenance, troubleshooting, and spare-parts documentation.
OEM/ODM Customization and Project Support
Customization options depend on the product platform, target market, and order requirements.
Hardware and Appearance
Branding: Confirm available enclosure colors, logo application, display language, and user-interface customization.
Charging Configuration: Specify connector type, cable length, outlet count, and compatible cooling options.
Payment and Communication: Confirm supported payment hardware, network interfaces, and backend configuration.
Project Engineering and Delivery
Technical Review: Assess site power availability, vehicle requirements, installation layout, and local compliance needs.
Configuration Approval: Confirm the final bill of materials, interfaces, software requirements, and approved technical datasheet.
Production and Inspection: Agree on inspection criteria, factory testing scope, and required documentation.
Delivery and Commissioning: Define delivery schedule, installation responsibilities, commissioning scope, spare-parts requirements, and warranty terms in the project quotation.
FAQ
Q: How do I select the right DC fast charger power rating?
A: Start with the target vehicle types, expected daily energy demand, average dwell time, simultaneous charging requirements, and available grid capacity. Then compare charger output curves and power-sharing capabilities against vehicle charging limits. A site load assessment is recommended before finalizing the rating.
Q: Can two vehicles charge simultaneously at full rated power?
A: Not necessarily. The available power depends on the charger's total rated capacity, internal power architecture, connected vehicles, and configured allocation strategy. Request the model-specific power-sharing matrix to verify the output available to each vehicle during simultaneous charging.
Q: Does the charger support different vehicle connector standards?
A: Connector options depend on the model and destination market. Confirm the required connector, vehicle communication compatibility, electrical limits, and applicable compliance documents before ordering.
Q: Can the charger connect to a third-party charging management platform?
A: Potentially, subject to the implemented OCPP version, supported functions, firmware, and platform compatibility. Confirm the required protocol version and integration scope with both the charger supplier and the backend provider.
Q: What compliance documents are available for international projects?
A: Available documentation depends on the exact model and destination market. Specify the installation country during quotation so the applicable electrical safety, EMC, connector, and grid requirements can be reviewed against the relevant product documents.
Q: What information is required for a project quotation?
A: Provide the destination country, application, required power, number of dispensers and outlets, connector types, available grid supply, expected simultaneous charging demand, backend requirements, order quantity, and target delivery date. Site drawings and load information are helpful for engineering review.
