Product Testing and Certification

Charging stations–SIQ offers full support in testing and certification

31. March 2021 Tibor Kokelj, Damjan Repar


The worldwide usage and production of electric vehicles are constantly increasing and SIQ successfully follows those trends. We are one of the few laboratories in the EU with the ability to test AC and DC charging stations. SIQ can issue test reports and certificates ensuring that such products can be sold on the world market without additional national testing.

There are two types of charging for electric vehicles: AC charging and DC charging. AC charging at home or work is limited to the domestic connectors with a maximum of 16 to 25 A per phase, which represents an approximate 3.6 to 5.8 kW/phase under ideal conditions. The first produced models had a rated power of 3.6 kW, while today the most common AC charging stations have a rated power from 7.2 kW up to 22 kW, which is the upper limit. DC charging stations typically have a rated power between 50 and 180 kW and provide charging via the two most common systems: CCS (Combined Charging System) and CHAdeMO (Japanese standard).

SIQ has been actively cooperating with electric vehicle manufacturers or their suppliers since 2009. We have obtained the required accreditations and equipment which enable us to offer testing of AC and DC charging stations according to the applicable standards at one location.

Our experts perform electrical safety testing according to IEC 61851-1: 2017 / EN 61851-1: 2019 standards and determine electromagnetic compatibility according to IEC 61851-21-2: 2018. We also perform all the environmental tests and EMC tests required for radio modules.

Do you need help to determine the scope of testing, expert advice, or help to prepare an EMC testing plan?
