Tesla App Update 4.53: Powershare Limit Control, Automatic Damage Detection, Brake-by-Wire

Adjust Powershare Limit in App

The Tesla app now lets Cybertruck owners set the Powershare limit directly from their phone, a setting that previously had to be adjusted in the vehicle.

Powershare enables the Cybertruck to supply electricity to a home much like a Powerwall. To prevent a home from draining the traction battery completely, users can define a Powershare limit that keeps a portion of the battery reserved for driving.

Availability: worldwide.

Automated Damage Detection

For vehicle trade-ins, the app now offers photo templates that show exactly how each image should be framed. There are hundreds of these templates to guide customers through the process.

Submitted photos are processed by a system that automatically assesses the vehicle and flags any damage.

The visual outlines help clarify what the final image should capture. It is not yet certain whether these outlines are overlaid while taking the photo or simply displayed as examples.

There are more than 400 templates spanning numerous makes and models, including both Teslas and third-party vehicles, with variations for left- and right-hand drive and body types such as sedans, SUVs, minivans, and others.

Applies to Models S, 3, X, Y, and Cybertruck.

Cybercab to Use Brake-by-Wire

A new feedback item labeled "Brakes SW - Brake-by-Wire (Cybercab)" indicates that Cybercab will use a brake-by-wire system instead of a traditional mechanical linkage.

With brake-by-wire, pressing the brake sends an electronic signal that actuates the calipers, similar in concept to steer-by-wire, rather than relying on a direct physical connection.

In other vehicles, Full Self-Driving moves the brake pedal, which remains tied to the braking hardware. As Cybercab transitions away from the test-phase brake pedal, removing unnecessary linkages enables direct electronic control of the calipers.

More Smart Breaker Support

This release adds more code supporting upcoming Smart Breaker integration.

Smart breakers add sensors and connectivity (such as Wi‑Fi) to standard electrical panel breakers, allowing systems like Powerwall to switch circuits on or off.

In addition to control, they can provide detailed insight into the energy usage of connected devices.

For homes equipped with Smart Breakers, customers will be able to choose which circuits remain on during an outage and which can be turned off to conserve Powerwall energy.

New strings observed in this update include:

• "For breakers you need while off-grid"
• "energy_customize_smart_breakers_always_on_title"
• "Learn About Smart Breakers"
• "For breakers you don't need while off-grid"
