Last week, SparkyNinja provided the UKs first largescale EVSE electrical training.
These new courses were a combination of the following:
- 2921-32: Design and quality assurance of largescale commercial electric vehicle charging installations
- 2921-33: Installation and mainteannce of largescale commercial electrical vehicle charging installations.
SparkyNinja has chosen to combine these qualifications in our delivery as the training outcomes between the two do significantly overlap - with only minor differences. However the option to only sit one of these two assessments is available on enquiry.
A great calibre of candidates attended the course with many who are actively involved in the design and installation of largescale EVSE and this created great opportunities for discussions on the challenges within the IET Code of Practice and the demand of the industry.
We were able to identify frustrating aspects of the City and Guilds assessments and these have been fed back with recommendations for improvements.
We were also able to identify contradictions within the IET Code of Practice and recognise that most have been amended in the upcoming 5th edition - for which I had the public draft available for reference.
Some interesting points discussed, which aren't specifically detailed within the IET CoP, IET CoP supplement for petrol fillings stations or BS 7671 include:
- Suitable considerations for accessibility and welfare - such as PAS 1899
- Additional considerations for calculations with grouping factors
- DC cable calculation data for systems like the ABB 350 where the rectifier distributes the load from the power modules all onto one cable
- Communications with EVSE for responsibilities for maintenance - manufacturers may upgrade power modeules in rectifiers without informing the designer and therefore the DC cabling may be vulnerable from overvoltage
These points and others will be added to the upcoming largescale EVSE courses and any adjustments or updates made by the IET or City and Guilds are included.
Our next largescale EVSE course is in July, you can book here.
