What are the differences in equipment selection between production-line aging tests and laboratory R&D tests?

VILVA follows inspection and commissioning procedures before equipment delivery. Its customized-service process includes assembly, commissioning, inspection, aging testing, calibration, and delivery, helping verify equipment performance before shipment.

For customized testing equipment, the inspection scope can be defined according to the agreed technical specification and project requirements. Depending on the equipment, this may include electrical performance verification, functional testing, load operation, control-system checks, and other applicable inspection items.

For an official factory inspection report, it should be confirmed according to the product model and sales contract. Customers with special acceptance requirements can provide their inspection checklist or test protocol in advance so that the applicable factory testing and documentation can be incorporated into the project.

Portable EV charger test units are particularly suitable for applications where testing equipment needs to be moved between charging stations or deployed directly at the installation site. Typical applications include on-site charger acceptance, charging-station operation & maintenance, fault diagnosis and random field inspections.

VILVA's portable DC charging-pile tester is designed for full-load testing, production workshops, laboratories, installation and commissioning, maintenance, and upgrade or modification testing. For field applications, the required voltage range, output power, charging standard, communication protocol, and test functions should be confirmed in advance. VILVA can recommend a suitable portable configuration according to the charger type and intended inspection scenario.

A standard testing unit is normally configured around a defined test channel and charging interface, while simultaneous multi-charger testing requires a system architecture designed for multiple channels. VILVA can develop customized testing solutions when customers need to test multiple charging units or production-line stations in parallel.

Multi-channel solutions can be designed according to the number of chargers, voltage and power requirements, communication protocols, load-sharing architecture, control method, and required test sequence. This approach can help manufacturers increase testing throughput while maintaining consistent test conditions across multiple units.

For a multi-station project, customers should provide the number and type of chargers to be tested simultaneously, rated power, charging standards, required test items, and production-line takt time. VILVA can then evaluate the required channel configuration and propose a suitable customized testing system.

Yes. VILVA provides EV charger testing and aging equipment for applications that require prolonged operation and performance verification. The appropriate configuration depends on the charger's rated voltage, output power, cooling requirements, test profile, and required duration.

For long-duration aging tests, the test system must be selected according to the charger's actual operating conditions and the required loading profile. The equipment can be configured around the required test procedure to provide controlled and repeatable loading during the aging process.

The specific maximum continuous operating duration should be confirmed against the selected model and test configuration. If a project requires a defined aging period, such as 72 hours or longer, customers should specify the required duration, loading condition, voltage, power, and test cycle so that VILVA can confirm the appropriate equipment specification rather than treating 72 hours as a universal rating.

Yes, VILVA offers EV charger testing equipment supporting international charging standards, with the applicable standards depending on the model and configuration. The company's EVD DC charging-pile tester explicitly supports IEC 61851 for power transmission and also references ISO 15118, DIN 70121, and IEC 62196 for relevant communication and vehicle-interface requirements.

The equipment can therefore be configured for testing projects involving different regional charging standards, which is particularly relevant to EV charger manufacturers and laboratories serving international markets. Certification requirements should be evaluated separately from protocol support. IEC 61851 compatibility does not by itself mean that every model carries CE certification. For an export project, customers should specify the destination market and required standards so that VILVA can confirm the applicable technical and certification documentation for the selected equipment.

VILVA offers different equipment configurations for EV charger testing, including portable solutions for field testing and application-specific systems for laboratories, production environments, and commissioning projects. Both portable on-site models and rack-mounted units for laboratories and production lines are available. Portable units are ideal for field acceptance, while rack-mounted versions suit laboratory R&D and production-line aging tests.

The appropriate form factor depends on the required testing power, test environment, mobility requirements, control system, and available installation space. Laboratory or production-line applications may favor an integrated or fixed installation, while field acceptance and maintenance work can benefit from a more portable configuration.

Dimensions, weight, voltage range, power capacity, and connection configuration vary by model. Customers should provide the intended application and required test capacity so that VILVA can recommend a suitable equipment configuration rather than applying one standard size to all projects.
