Tesla Fires Many on Charger Team, Raising Doubts About Expansion

The carmaker dismissed 500 employees in a unit that was critical to its success and seen as important to the future of electric vehicle sales in the United States.

Elon Musk has gutted the part of Tesla responsible for building electric vehicle charging stations, sowing uncertainty about the future of the largest and most reliable U.S. charging network.

The layoffs of about 500 Tesla employees, which many of them posted about on social media on Tuesday, raised questions about deals that Mr. Musk, Tesla’s chief executive, struck with the leaders of General Motors, Ford Motor and other automakers last year allowing cars made by other companies to use Tesla Supercharger stations.

Tesla’s agreements with other makers of electric cars assured buyers that they would be able to find fast chargers on road trips, addressing one of the main reasons that many people are hesitant to buy such cars. It was also seen as a coup for Mr. Musk, validating Tesla’s technology and giving the company outsize influence over the auto industry.

Almost all major manufacturers announced plans to switch the hardware and software in their cars to make them compatible with Tesla’s chargers. Ford has been mailing adapters to owners of its older electric vehicles so they can connect to Tesla’s chargers.

Mr. Musk said on X, the social media site he owns, that Tesla would slow down construction of new charging stations and increase its “focus on 100% uptime and expansion of existing locations.”

On Monday, in an email to employees that was reviewed by The New York Times, Mr. Musk said he would dissolve the “entire group of approximately 500 people” that had worked on building new Supercharger stations. In that message, he said the company would finish stations under construction and build some new ones “where critical.”
