A critical flaw in Tesla’s Cybertruck has been revealed by an engineer, explaining why onboard power outlets are unusable during supercharging, due to the vehicle’s complex hardware limitations.
Engineer Acknowledges Need for Development
There appears to be no simple solution to the problem that Tesla engineer Wes Morrill brought up on Sunday on X when he explained to Cybertruck owners why they are unable to utilize the vehicle's power outlets while supercharging.
“The AC/DC converter used to take grid AC and convert it to DC to charge the HV battery is the same hardware used to generate the AC grid you use for your onboard power,” as Morrill explained on X.
Power Converter Renders Outlets Useless During Charging
Because the power converter gear is rendered inoperable during supercharging, the driver is unable to use the power outlets; instead, DC voltage is provided directly to the vehicle battery.
There is a solution that can be developed, but it will take "time to develop," as the chief engineer for Cybertruck put it.
Morrill responded to a user who questioned the omission of this feature during the vehicle's development by saying, “If you are charging with AC power, you likely can plug whatever needs power into the same grid supplying power for the truck. It’s a pretty small use case to need to AC charge and simultaneously grid form with the truck.”
In the front, rear, and truck bed of the Cybertruck, you'll find many outlets where you may charge your phone or tools. The 120V/240V plugs located in the truck bed allow the Cybertruck to charge other electric vehicles or run tools, according to Tesla.
Cybertruck Production Set for Major Expansion
Per Benzinga, the Cybertruck was first delivered by Tesla in November 2023, and the company is already increasing production in preparation for a 250,000 unit annual delivery target beginning in 2025. According to Elon Musk, CEO of Tesla, the main problem with increasing Cybertruck deliveries is manufacturing, not demand.
