FAQ
Q: What is the difference between a DC wallbox charger and an AC wallbox charger?
A: An AC wallbox supplies alternating current, which the vehicle's onboard charger converts for battery charging. A DC wallbox performs AC-to-DC conversion within the charging equipment and supplies controlled DC power to the vehicle battery system. Actual charging speed depends on charger output, vehicle capability, battery conditions, and the charging profile.
Q: Can a 20–60 kW DC wallbox use an existing commercial power supply?
A: Possibly. Suitability depends on available electrical capacity, existing building loads, the charger's input requirements, protective devices, and local utility requirements. A site load assessment should be completed before installation.
Q: Can one dual-gun charger charge two vehicles simultaneously?
A: That depends on the selected model. Confirm whether simultaneous charging is supported, the total available output power, the maximum power per connector, and how power is allocated between connected vehicles.
Q: How can I verify compatibility with an existing CSMS platform?
A: Confirm the charger's supported OCPP version and required functions with both the charger supplier and CSMS provider. Platform compatibility should be validated through interface documentation and, where necessary, integration testing before bulk deployment.
Q: Which certifications and compliance documents are available?
A: Documentation depends on the model and destination market. Buyers should request the applicable certificates, declarations of conformity, and test reports and verify that their scope covers the selected equipment and intended application.
Q: What are the MOQ and lead time for OEM/ODM orders?
A: MOQ and lead time depend on the base model, customization scope, component availability, sample approval, and order quantity. Confirm these details in the quotation before placing the order.
