An EV accessory maker has reached out to Tesla as part of its efforts to ensure that its Supercharger extension cords are up to par with the electric vehicle maker’s safety standards. The company’s efforts came on the heels of a Tesla engineer’s comments warning EV owners about the potential risks of using extension cords in Supercharger stations.
Earlier this week, Tesla Cybertruck lead engineer Wes Morrill posted a warning in response to an EV owner who was asking about A2Z EV/EVSE’s upcoming NACS DC extension cord. As per the Tesla engineer, using aftermarket extension cords on Superchargers could be risky, and he has seen multiple instances of cables overheating and shorting.
“There’s a temperature measurement in the handle and the Supercharger derates based on that temperature. With the extension cable, that safety goes away. On top of adding an additional junction which generates heat, making matters worse,” Morrill wrote in a post on X.
We would truly love to discuss this further with you and understand your arguments. We take safety very seriously.
Thank you.

In response to the Tesla Cybertruck lead engineer’s post, A2Z EV/EVSE noted that they would love to work with Tesla to make sure the electric vehicle maker’s safety concerns are fully addressed with their products. The EV accessories maker also highlighted that its DC extension cord already features a number of safety systems, and that its products will not be released to consumers until safety tests are completed.
Done ✅

“We are open to a collaboration with Tesla,” the EV accessory maker wrote. Morrill, for his part, responded by asking the accessory maker to send him a direct message so they could discuss his safety concerns.
We have reached out to @wmorrill3 and will engage in dialogue in order to have his opinion on our DC extension cord. Maybe we can learn from his experience and adjust accordingly.
A few key points for everyone else :

Tesla has worked with aftermarket accessory makers in the past. Earlier this year alone, Tesla came to an agreement with EVject, whose popular “Escape Connector” initially incited a lawsuit from the electric vehicle maker. After comments from the EV community about the matter, as well as Elon Musk stating that he would look into the matter, Tesla and EVject came to an agreement.
In a post on its official Tesla Charging account on X, the electric vehicle maker noted that it is open to working with OEMs to develop safe accessories for its customers. “Tesla and OEMs will keep working with the industry to provide safe adapters and develop common sense regulatory standards,” Tesla Charging wrote in a post.
