Prof. Misty Blessley at Temple U. looks into an issue facing EV owners.
New Jersey is removing Tesla Superchargers from Turnpike and Parkway service areas and replacing them with universal chargers provided by Applegreen Electric. These new stations will feature CCS1, CHAdeMO, and J1772 connectors, making them compatible with a wider range of EVs. Tesla owners can use these chargers with adapters. Most newer Tesla models can accommodate J1772 (Level 2) and CCS (DC fast charging) connections through external adapters.
This shift reflects a broader trend toward open-access infrastructure aimed at increasing accessibility for all EV drivers. It also introduces new OM considerations around the production, availability, and use of adapters.
The Shift Toward Open Infrastructure
New Jersey’s decision mirrors historical tech battles between proprietary systems and open standards. Tesla, like Apple in its early days, built a closed ecosystem. The state’s move to universal chargers signals a shift toward interoperability over exclusivity. As one article put it, “Up until recently, the vast network of more than 1,600 Tesla Supercharger fast EV charging stations in the U.S. was a perk exclusive to Tesla owners.” That exclusivity is
now being replaced with inclusivity, with the cost falling on Tesla drivers now being dependent on an external device.
In this context, adapters become the modern equivalent of USB driver software, seemingly minor components that play a major role in user experience and system reliability.
Adapter Implications for Operations and Supply Chain
Forecasting and Demand Planning: Widespread reliance on adapters will drive new demand. Manufacturers must scale production, distribution, and after-sales support.
Inventory Management: Retailers and even rest stops may need to stock or rent adapters, creating SKU complexity.
Station Capacity: Adapters can increase setup time, and Level 2 chargers provide only 13–25 miles of range per hour—far slower than Tesla’s V3 Superchargers (over 200 miles in 15 minutes), potentially reducing the number of EVs that can be charged at a station.
Risk and Reliability: Adapters introduce new points of failure because they are mechanical devices prone to wear, damage, or user error. This raises customer service and warranty cost concerns.
Classroom discussion questions:
1. In Ch. 11 of your Heizer/Render/Munson textbook, component standardization is discussed. What are the benefits of standardizing EVs and charging stations?
2. What advice would you provide to operations managers on the adapter implications mentioned above?
