[Live Webinar] Electric Vehicle Charging – Engineering Opportunities
Intended Audience: Electrical Engineers
Credits: 2 PDH Units
When: Wednesday 5/24. 2 – 4 pm ET
70 STUDENTS ENROLLED
In the United States, there are now more than three million EVs on the road and over 132,000 public EV chargers across the country. The Edison Electric Institute estimates that by 2030, the number of EVs will exceed 18 million, and the U.S. has set a goal of half of all new vehicle sales in 2030 to be EVs. In Europe, adoption in many countries is occurring at an even faster rate. Norway has set a goal of all new vehicles sold in 2025 to be electric.
All of these vehicles will need access to charging facilities, whether at home, at work, at play or while traveling. While EV charger technology is evolving rapidly, there are certain electrical basics that will always be needed in order to properly design the power supplies to these chargers. This 2-hour webinar takes an in-depth look at the options for providing power to these stations at an assortment of locations, including a look at many of the various Code requirements for proper design and installation. All three levels of charging are considered, with a close look at charging voltages, currents, power and charging times. Single phase and 3-phase supply systems are discussed in detail.
Date: Wednesday. May 24. 2023. Starts: 2 – 4 pm ET

Electric Vehicle Charging - Engineering Opportunities
The seminar delivered the information as advertised. The calculations are helpful when trying to optimize designs and they are well aligned with typical NEC 220 calculations so that is good input for the engineers that have to justify dollars and provide calculations to the AHJ. I would like to see more info on harmonics for single phase and for three phase chargers. As EVs saturate the utility distribution system, harmonics can become an issue. This phenomenon occurred during the glut of energy efficient lighting in the 90s and then limits on harmonics had to be specified and this was accomplished by adding filters, but, damage was done in some areas form the lack of attention to details form harmonics and then as the equipment saturates the power system. We also see this with PV saturation where the OPV starts to impact the 60-cycle frequency. Harmonics, harmonic impacts, harmonic mitigation and harmonic limits, would be a nice topic to add to the content.
Municipal Viewpoint
As a municipality who has an electric department and initially entering into the EV charging world the first hour was helpful for considerations of the types/levels of charging we may look to consider placing for public use. The second hour was directly geared towards electrical engineers and got deep into the weeds of three phase circuitry. It was not nearly as useful.
Electric Vehicle Charging – Engineering Opportunities
Good course. Charging station design is complicated and changing rapidly with emerging technoligies.
Good But Long on Calculations
The information pertaining specifically to EV Charging was interesting and helpful. Apparent that the speaker is well informed. The detailed calculations and electrical theory, though, were not really useful as far as learning about EV codes, opportunities and other practical matters. The calcs and theory should be abbreviated for this webinar and left for another separate webinar.
The website is not letting me pick four stars, but that is my intention.
EV Charging - Engineering Opportunities - Webinar / Comments
I tried to click on four stars above, but the software would not register the selection; tried it a few times.
The course was informative and interesting, though we ran out of time at the end. It could have been extended another 20 minutes to cover the material.
A weakness of the format is that users can’t easily download the Q&A except by cutting and pasting as you go, and the chat can’t be copied at all. Also, the instructor couldn’t give written answers to the questions, though it would be helpful if someone else could enter in answers for future reference, if not in real time, then afterwards for all participants to gain that knowledge.
