Key Features and Applications
Designed Around Commercial Charging Requirements
Fleet Depots and Delivery Vehicles: Supports scheduled vehicle charging where charging windows, fleet utilization, and available electrical capacity determine the required power rating.
Dealerships and Service Centers: Provides DC charging for vehicle preparation, customer handover, and workshop operations where compatible vehicles and site power are available.
Commercial Parking Facilities: Wall-mounted installation can help preserve usable floor space, subject to wall strength, cable routing, clearances, and local installation requirements.
Workplaces and Destination Facilities: Offers an alternative to AC charging where faster charging is needed and the electrical infrastructure supports DC equipment.
Vehicle and Platform Compatibility
Compatibility must be evaluated against the vehicle's charging interface, voltage range, communication requirements, and charging behavior. Vehicle names or software-platform compatibility should be published only when supported by documented testing.
Manufacturing and Quality Control
Quality Assurance for B2B Supply
Quality-control procedures should be documented and applied to the supplied configuration, with inspection records available according to the agreed purchase specification.
Incoming Component Inspection: Verify purchased components against approved specifications and incoming inspection criteria.
Assembly Inspection: Check wiring, connections, mechanical assembly, labeling, and applicable safety-related components.
Functional and Electrical Testing: Verify output performance, protection functions, communication, and other agreed test items.
Final Inspection and Traceability: Record serial numbers, inspection results, and applicable production test reports for shipped units.
Quality Documentation
Inspection plans, test reports, quality-system certificates, and traceability records are available subject to actual documentation, certification status, and project requirements. Any claims concerning full-load aging duration, 100% testing coverage, or specific ISO certifications must be confirmed before publication.
OEM/ODM and Private-Label Options
Configuration Support for Distributors and Charging Brands
Branding and Appearance: Evaluate private-label housing, logos, colors, and product labeling according to order requirements.
Hardware Configuration: Discuss supported power ratings, connector types, cable lengths, mounting accessories, and payment-terminal integration.
Software and Connectivity: Confirm supported OCPP functions, backend connection settings, language options, and firmware customization scope.
Regional Requirements: Review local electrical requirements, applicable standards, labeling, and certification needs before confirming a market-specific configuration.
MOQ, sample availability, customization scope, and production lead time should be confirmed after technical review and agreement on the required configuration.

FAQ
Q: What is the difference between a DC wallbox charger and an AC charger?
A: A DC charger converts AC input into regulated DC power for the vehicle's battery charging system. An AC charger supplies AC power, which is converted by the vehicle's onboard charger. Actual charging speed depends on both the charging equipment and the vehicle.
Q: How do I choose between 20 kW, 30 kW, 40 kW, and 60 kW?
A: Consider vehicle charging limits, battery capacity, daily energy demand, parking duration, and available site power. Confirm the charger's output characteristics at the vehicle's operating voltage before selecting a model.
Q: Can the charger charge two vehicles simultaneously?
A: Only configurations specifically designed and equipped for simultaneous charging can support this function. Confirm the number of outputs, per-outlet power limits, and power-sharing behavior for the selected model.
Q: Does the charger support OCPP?
A: OCPP support depends on the installed communication hardware and firmware. Confirm the supported version, required functions, and compatibility with the intended charging management platform before ordering.
Q: Which certifications and documents are available?
A: Documentation depends on the exact model, destination market, and certification status. Request the applicable declarations, test reports, product labels, and other required documents during technical review.
Q: Can the charger be customized for private-label projects?
A: Branding and selected hardware or software options can be evaluated for OEM/ODM projects. MOQ, lead time, available modifications, and compliance implications depend on the requested configuration.
