 EN62109-1:2010 test EN62109-2:2011 test



I. Standard Overview


EN62109-1:2010 specifies the "General Safety Requirements" for power conversion equipment used in photovoltaic power generation systems, which applies to the safety design and evaluation of all power conversion equipment, covering core indicators such as basic electrical safety, mechanical protection, and environmental adaptability. EN62109-2:2011, based on the first part, refines the special requirements for "photovoltaic inverters", including specific test contents such as electrical characteristics, protection functions, and electromagnetic compatibility (EMC). It is the core basis for market access in the EU. II. Core Test Items


(1) EN62109-1:2010


Environmental adaptability: Test the operational stability of equipment under extreme temperature, humidity, and altitude conditions. Electrical shock protection: Evaluate insulation strength, grounding continuity, and enclosure protection level (such as IP rating). Mechanical safety: Verify the structural strength and vibration resistance of equipment to prevent potential safety hazards caused by mechanical failure. (II) EN62109-2:2011


Electrical performance: including measurement and verification of parameters such as output voltage/current accuracy, power factor, and efficiency. Protection functions: overvoltage/undervoltage protection; overcurrent/short circuit protection; overheat protection; islanding protection. EMC testing: based on the EN 61000 series of standards, evaluates the equipment's immunity to interference and emission levels in an electromagnetic environment. Fire safety: material flame retardancy testing and verification of thermal runaway protection under abnormal operating conditions. III. Certification process


Document preparation: Provide product technical specifications, circuit diagrams, lists of key components (including CE certified components), and user manuals. Sample testing: The laboratory completes tests on electrical safety, EMC, environmental adaptability, etc. according to standard requirements, records the test data, and generates a detailed report. Report review: The certification body verifies the test results and issues a CE certification certificate after confirming compliance with the standards. Continuous compliance: Manufacturers need to track standard updates to ensure that products continue to comply with EU regulatory requirements. IV. Linkage with other standards


Compared with the IEC 61851 series: EN62109 focuses on the safety of the power conversion equipment itself, while the IEC 61851 series (such as IEC 61851-21-1) emphasizes the interactive compatibility between charging stations and vehicles, as well as EMC requirements. Compared with UL 2594: UL 2594 focuses on the safety certification of charging stations in the North American market, while EN62109 places more emphasis on the comprehensive safety assessment of inverters and energy storage systems in the EU market. V. Notes


Scope of application: Applicable only to off-vehicle photovoltaic inverters and energy storage systems, excluding wireless charging equipment. Regulatory updates: Regular verification of standard versions is required to avoid certification invalidation due to standard revisions

Power Bank Safety Upgrade: First Mandatory National Standard Issued

图片
 Power Bank Safety Upgrade: First Mandatory National Standard Issued my country's first mandatory national standard, the "Technical Specification for Safety of Power Banks," was published on March 31, 2026, and will officially take effect on April 1, 2027. This standard aims to end long-standing problems in the power bank industry, such as falsely advertised capacity, substandard battery cells, and frequent safety incidents. The new regulation introduces several stringent technical requirements, mandating that battery cells pass a needle penetration test (without catching fire or exploding), and strengthening thermal abuse testing; it also adds tests for whole-device drop and crushing, requires products to be labeled with a safe service life, and improves various protection mechanisms.

EN IEC 62680-1-3/62680-1-2 EU Electronics Standards

图片
To reduce e-waste, the EU is committed to promoting a unified charging technology and interface that supports a variety of electronic products. On November 23, 2022, the EU issued Directive EN IEC 62680-1-3/62680-1-2, requiring electronic product manufacturers to use USB-C charging interface technology in their products. It also requires small and medium-sized portable electronic devices such as mobile phones, tablets, and cameras, as well as laptops, to comply with the USB-C charging interface requirement by 2024 and 2026, respectively. The IEC 62680 testing equipment GRL-USB-PD-C2-EPR, formerly the USB-IF Association's USB PD certification testing instrument, performs PD protocol certification testing. IEC 62680-1-2 and IEC 62680-1-3 incorporate the USB-IF USB PD and Type-C specifications and are currently used for protocol testing and certification corresponding to IEC 62680. IEC 62680-1-2 primarily defines the USB PD power supply specification; IEC 62680-1-3 is a specification ...
