This project will determine the level of harmonics and flicker observed during the charging of EVs and document the emissions conducted back onto the electrical distribution network. 1. Testing of at least 15 electric vehicles2. Recording of power quality data for specific vehicle types3. EV power quality data analysed for compliance with relevant standards4. Report on EV Emissions Testing completed

Electric Vehicle (EV) manufacturers are unwilling to share the specific harmonic data on the EVs currently in circulation in the UK. Vehicles should be compliant with harmonized EU standards under UNECE R10, but various versions of this standard apply to the existing fleet and there is further uncertainly over which standards apply due to the transitional provisions for conformity. Furthermore UNECE R10 only requires compliance with 61000-3-11 and 61000-3-12 for charging over 16A, which does not provide unconditional connection to the network. Without confirmation of the standards these vehicles comply with, the customer risks facing increased network charges, either due to conservative reinforcement requirements, or widespread reactive reinforcement schemes to ensure the network remains within limits. Identifying the EVs which can be classed as non-disturbing and meet the technical requirements of 61000-3-2 and 61000-3-3 will enable DNOs to assess and approve these connections quicker. This project will assess the harmonic disturbance of EVs by carrying out repeated charge and discharge tests for a range of vehicles and charging levels on monitored EV Chargepoints. The results of the monitoring will be analysed and a report created on their level of disturbance and standards met.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
