This certification mark refers to the testing of plugs, socket outlets, vehicle connectors and vehicle inlets for conductive, i.e. wired, charging of electric vehicles. The charging systems have the following maximum voltages:
- 690 V AC 50 Hz to 60 Hz, at a max. rated current of 250 A,
- 1500 V DC at a max. rated current of 400 A
The test method developed by TÜV SÜD is based on the following standards: IEC/EN 62196-1, IEC/EN 62196-2, IEC/EN 62196-3 (Plugs, socket-outlets, vehicle connectors and vehicle inlets – Conductive charging of electric vehicles – Part 1: General requirements; Part 2: Dimensional compatibility and interchangeability requirements for a.c. pin and contact-tube accessories; Part 3: Dimensional compatibility and interchangeability requirements for d.c. and a.c./d.c. pin and contact-tube vehicle couplers).
Electrical tests conducted: The product certified by TÜV SÜD was tested for electrical safety and for its capability to withstand short-circuit currents induced when the component is separated from the power supply. Testing also covered correct design of the electrical connections and the effectiveness of the locking devices during charging.
All rubber and thermoplastic materials included in the certified product were tested for their resistance to ageing. In addition, the products were tested for cable strain relief, the IP rating (which indicates the degree of protection against the ingress of liquids and solids into the component), corrosion and resistance to rusting of metal parts, the equipment’s resistance to damage when driven over by a vehicle, and the correct design of the component.
This certification mark refers to conductive systems used for on-board and off-board equipment for charging electric road vehicles at standard AC voltages up to 1000 V and DC voltages up to 1500 V. Electric road vehicles comprise all road-vehicles including plug-in hybrid electric vehicles which are powered fully or partially by rechargeable energy storage systems (RESS). The term does not apply to trolley buses, rail vehicles, industrial trucks and vehicles designed primarily for off-road use.
The test method developed by TÜV SÜD is based on the following standards: IEC/EN 61851-1 IEC/EN 61851-22 or IEC/EN 61851-23 (Electrical equipment of electric road vehicles – electric vehicle conductive charging system – Part 1: General requirements; Part 22: AC electric vehicle charging station; Part 23: DC electric vehicle charging station).
The product certified by TÜV SÜD was tested for electrical safety when used by the user. The product was also tested for electromagnetic compatibility.
The TÜV SÜD certification mark with this statement indicates that the certified product is able to withstand mechanical influences. In addition the product was tested for its chemical resistance to liquids and its IP rating, i.e. the degree of protection against the ingress of liquids and solids into the component.
Periodic surveillance and/or monitoring of the manufacture of a product constitutes the basic premise for certification that includes the award of a certification mark. Certification always requires product testing and regular factory inspections.
As a third-party expert organisation, TÜV SÜD Product Service verifies that the manufacturer is able to maintain consistent quality in line with the requirements throughout high-volume production and has established the necessary quality system, including incoming goods inspections, lists of materials and final product testing.
In addition, calibration of the necessary measuring and monitoring equipment must be ensured. Surveillance and/or monitoring covers the testing of safety-critical components and other materials used. If unauthorised changes are made to the product, the certificate will become invalid (withdrawn) and the TÜV SÜD certification mark may no longer be used.
