Campus Electric Transit
University of Michigan | Washtenaw County
Widespread use of electric vehicles (EVs) on large university campuses offers significant possibilities but also presents challenges. Possibilities include reduced carbon emissions, aligning with sustainability goals, as EVs produce zero tailpipe emissions compared to gasoline-powered vehicles. Campuses could deploy electric shuttles, maintenance vehicles, or shared EV fleets, decreasing reliance on fossil fuels. EVs could integrate with campus microgrids, leveraging renewable energy sources like solar panels. They also promote quieter environments, reducing noise pollution in academic settings. Universities could foster innovation by integrating EV infrastructure into research, such as smart grid technology or battery development.
Pros include environmental benefits, lower operating costs (electricity is cheaper than fuel), and enhanced campus branding as eco-friendly. EVs require less maintenance, saving long-term costs. Students and staff benefit from cleaner air and modern transportation options.
Cons include high upfront costs for EVs and charging infrastructure, straining budgets. Limited range and charging times may disrupt campus operations, especially for time-sensitive tasks. Charging station availability could lead to congestion or inequitable access. Battery production raises ethical concerns about resource extraction. Retrofitting existing fleets and managing grid demand pose logistical hurdles.
Balancing these factors requires strategic planning, but EVs could transform campus mobility sustainably.
We have followed standards setting action in this domain since 1993. During todays colloquium at 15:00 UTC we will answer questions about our involvement, guided by our Safer-Simpler-Lower Cost – Longer Lasting advocacy in all relevant standards.

Wireless EV Charging
Wireless electric vehicle charging on streets uses electromagnetic induction to transfer power without physical connectors. A primary coil, embedded in the road surface, generates an alternating magnetic field when energized by an external power source. A secondary coil, installed on the EV’s underside, captures this field, inducing an electric current that charges the vehicle’s battery. Efficient power transfer requires precise alignment between coils, often aided by sensors or magnetic guidance systems.
Operating typically at frequencies of 20–100 kHz, the system ensures safe, non-contact energy transfer with efficiencies up to 90%. Power levels vary from 3.3 kW for slow charging to 22 kW or higher for faster systems. Infrastructure includes power inverters, communication modules for vehicle-grid interaction, and safety mechanisms to prevent electromagnetic interference or hazards. Dynamic charging, where EVs charge while moving, extends this concept using sequential coil activation along roads.

2026 NEC First Draft: How Did We Get Here?
Public Input Transcript: First Draft | Public Comment Transcript: Second Draft
2023 National Electrical Code | Current Issues and Recent Research
August 5, 2021
The 2020 National Electrical Code (NEC) contains significant revisions to Article 625 Electric Vehicle Power Transfer Systems. Free access to this information is linked below:
You will need to set up a (free) account to view Article 625 or you may join our colloquium today.
Public input for the 2023 Edition of the NEC has already been received. The work of the assigned committee — Code Making Panel 12 — is linked below:
NFPA 70_A2022_NEC_P12_FD_PIReport_rev
Mighty spirited debate. Wireless charging from in-ground facilities employing magnetic resonance are noteworthy. Other Relevant Articles:
- Article 240: Overcurrent Protection: This article includes requirements for overcurrent protection devices that could be relevant for EV charging systems.
- Article 210: Branch Circuits: General requirements for branch circuits, which can include circuits dedicated to EVSE.
- Article 220: Load Calculations: Guidelines for calculating the electrical load for EVSE installations.
- Article 230: Services: General requirements for electrical service installations, which can be relevant for EVSE.
- Article 250: Grounding and Bonding: Requirements for grounding and bonding, which are critical for safety in EVSE installations.
Technical committees meet November – January to respond. In the intervening time it is helpful break down the ideas that were in play last cycle. The links below provide the access point:
Public Comment Report Panel 12
We find a fair amount of administrative and harmonization action; fairly common in any revision cycle. We have taken an interest in a few specific concepts that track in academic research construction industry literature:
- Correlation with Underwriters Laboratory product standards
- Bi-Directional Charging & Demand Response
- Connection to interactive power sources
As a wiring safety installation code — with a large installer and inspection constituency — the NEC is usually the starting point for designing the power chain to electric vehicles. There is close coupling between the NEC and product conformance organizations identified by NIST as Nationally Recognized Testing Laboratories; the subject of a separate post.

After the First Draft is released June 28th public comment is receivable until August 19th.
We typically do not duplicate the work of the 10’s of thousands of National Electrical Code instructors who will be fanning out across the nation to host training sessions for electrical professionals whose license requires mandatory continuing education. That space has been a crowded space for decades. Instead we co-host “transcript reading” sessions with the IEEE Education & Healthcare Facilities Committee to sort through specifics of the 2020 NEC and to develop some of the ideas that ran through 2020 proposals but did not make it to final ballot and which we are likely to see on the docket of the 2023 NEC revision. That committee meets online 4 times monthly. We also include Article 625 on the standing agenda of our Mobility colloquium; open to everyone. See our CALENDAR for the next online meeting

Force Majeure
In his books, The Black Swan and Antifragile, Nassim Nicholas Taleb observes that freak disasters—rare, high-impact events—are unpredictable and often underestimated due to their low probability. He calls these “Black Swan” events, characterized by their extreme rarity, severe consequences, and retrospective predictability. Taleb argues that people and systems are overly reliant on normalcy and linear models, ignoring the potential for such outliers.
These disasters expose the fragility of complex systems, like financial markets or infrastructure, which are unprepared for extreme shocks. In Antifragile, he contrasts fragile systems with antifragile ones, which thrive under stress. Taleb emphasizes that freak disasters are not anomalies but inevitable in a complex world, urging risk management that accounts for uncertainty rather than predictability. He critiques overconfidence in forecasting and advocates for building resilience to mitigate the devastating effects of these unpredictable events.
We cover this ground, more than tangentially, in our activism in disaster management standards setting. Our coverage of this topic dates back to 1993 which the links below should reveal. We will expand upon this topic as more information is derived from this past week’s events in Kerr County Texas.
