AUSTIN, Texas – According to numerous media reports and social media posts, the latest Tesla software update will enable one-pedal driving, a capability facilitated by regenerative braking, even when it normally might not work.
When the driver takes their foot off the accelerator in an electric or hybrid-electric vehicle, the electric motor turns into a generator. This sends energy to the batteries, which is known as regenerative braking.
In some cases, regenerative braking might not occur. For example, when the battery is already fully charged, or in harsh weather conditions. In these instances, a one-pedal system might not work.
Tesla has developed a software fix to mitigate the conditions which might disable regenerative braking and render one-pedal driving impossible for its owners.
According to the notes accompanying Tesla software release 2022.16.0.3 for Model 3 and Model Y owners, “Your vehicle can now automatically apply regular brakes for consistent deceleration when regenerative braking is limited due to battery temperature or state of charge. To enable, tap Controls > Pedals & Steering > Apply Brakes When Regenerative Braking Is Limited.”
(According to other reports, “This change appears to be for non-LFP (lithium iron phosphate) cars only as LFP vehicles can utilize regenerative braking when at 100 percent.”
Some of the media reports indicate this software-update aspect is still in the testing phase and/or has not been disseminated to all Model 3 and Model Y owners (confirmed by a Model 3 owner).
Tesla does not respond to media inquiries, so further information is not available. The EV Report will continue to report on this story as information becomes available.
