New features#

Vehicle account linked to a memory function for customisable themes#

Mobile app functions: sign in to the mobile app by QR code, and authorise the mobile app key. Requires BYD App version ≥ V2.8.0.

Vehicle-side account functions: QR-code login and logout, personal information settings, personalisation settings. Built-in memory functions for the seat, the mirrors and the electric steering column, customisable themes, ambient lighting memory, cloud-key unlocking and account login. Which of these apply depends on the equipment level and differs between models.

Personal information settings — changing the avatar: only images stored locally on the vehicle can be used.

Available in 32 countries: United Kingdom, Italy, Israel, Hungary, Greece, Spain, Slovenia, Slovakia, Cyprus, Switzerland, Sweden, Portugal, Norway, Malta, Romania, Luxembourg, Lithuania, Latvia, Croatia, Czechia, Netherlands, Finland, France, Germany, Denmark, Poland, Iceland, Belgium, Bulgaria, Austria, Estonia and Ireland.

Head-unit “Account login” page with a QR code, the red line “Wi-Fi or cellular data (subject to fee collection) available”, the instruction “Open the BYD App, and scan the code for login” and a “No BYD App? Download” link. — Signing the car into an account is done by scanning this QR code with the BYD App.

Head-unit dialog “Account login” stating that the user can log in by scanning the code or with a cloud key, and that logging in again is needed if the account has not been used for a long time or the password has changed. — The car explains the two login routes and when a fresh login is required.

Energy consumption analysis added#

The driving energy consumption and the historical energy consumption can be viewed under Settings → Energy.

Driving Energy shows the driving energy consumption curve and its distribution for the last 50 km. Historical Energy tracks the vehicle’s total mileage and its average power consumption since it left the factory.

Energy Consumption Curve: the chart shows the equivalent energy consumption curve for the last 50 km driven. The energy consumption distribution for that trip is calculated and shown below the chart. The statistics exclude energy consumed while parked and contain only energy consumed while driving. The distribution appears after about 1 km of driving.

Energy Consumption Distribution: the share of energy consumed by drive, A/C, electrical appliances and others over the last 50 km. Drive is the energy used by the motor to move the car; A/C is the energy used by the air conditioning and its accessories; electrical appliances covers the instrument, the centre screen, the lighting system and other on-board consumers; others covers Vehicle To Load, thermal-management optimisation and further functions.

Head-unit Energy → “Driving Energy Consumption” tab with an “Energy Consumption Curve” line chart in kW·h/100 km over the last 50 km and an “Energy Consumption Distribution” row showing Drive, A/C, Electric Appliance and Others at 0 %. — The driving view plots consumption per 100 km over the last 50 km and splits it by consumer.

Head-unit Energy → “Historical Energy Consumption” tab with Companion Statistics showing ODO 16,165 km and Cumulative AEC 19.7 kW·h/100 km, plus a resettable Mileage Subtotal with mileage, average speed and electricity consumption. — The historical view holds lifetime odometer and average consumption plus a resettable trip subtotal.

BYD Assistant can be activated from the steering wheel while the screen is off#

Voice control buttons: with the screen switched off, pressing the voice control button wakes the screen and opens the voice bar.

Voice control added for switching heating and ventilation modes off#

“Hi BYD, Heizung ausschalten” (“Hi BYD, switch off the heating”) is answered with “Heizung deaktiviert” (“Heating deactivated”).

“Hi BYD, Lüftung ein-/ausschalten” (“Hi BYD, switch the ventilation on/off”) is answered with “Lüftung ein-/ausgeschaltet” (“Ventilation switched on/off”).

AC charging current limit added#

Setting path: Settings → Energy → Charging and Discharging → AC Charging Current Limit.

Selectable values: 6 A, 8 A, 10 A, 16 A, MAX. The current value refers to the current per phase during AC charging.

Example: at a 230 V three-phase charging station the 16 A setting means 16 A per phase, that is 48 A in total across the three phases. This is the maximum value of the AC charging power.

Use cases: limiting the vehicle’s charging power helps to avoid overloading the household supply and high electricity costs during peak periods. In homes with old electrical installations, prolonged charging at full power can cause overloads. In some countries time-dependent tiered tariffs apply at peak times, so charging at maximum power can become very expensive.

Head-unit Energy → “Charging and Discharging” tab showing Smart Charging, the Charging Port Immobilizer System set to Disable, a Battery Preheating toggle and an “AC Charging Current Limit (A)” selector starting at 6 and 8, partly covered by the toast “Current battery charging conditions are suitable, and no preheating is required”. — The new limit sits directly under battery preheating in Charging and Discharging.

Optimisations#

Android Auto and Apple CarPlay functionality optimised#

Android Auto: in gear P all functions are available. In any gear other than P only voice functions can be used, and video playback is not supported. Input method, settings and input length are no longer restricted.

CarPlay / Android Auto pop-up display rules: with reverse gear engaged and the reversing camera active, CP/AA pop-ups must not cover the camera view. Outside reverse gear, or outside the reversing camera view, CP/AA pop-ups are shown normally.

Notice for wireless CarPlay / Android Auto: if the user switches Wi-Fi on from the status bar while wireless CP/AA is in use, a pop-up notice appears.

Android Auto running on the head unit with a destination search for “kutuh” listing several places, and a music player panel on the right; the vehicle’s own control bar runs along the bottom. — Text entry in Android Auto is no longer length-restricted while parked.

Android Auto navigation view with a Wi-Fi toggle pulled down from the status bar and the dialog “Enabling Wi-Fi affects wireless Android Auto function. ON?” with OK and Cancel. — Switching Wi-Fi on during a wireless session now warns that the Android Auto link is affected.

System UI display and text prompts optimised#

A reset function has been added to the navigation bar customisation screen.

After Settings reset, Bluetooth is enabled by default.

Head-unit navigation bar customisation screen with Control and Apps tabs, a “Reset” button top right, and shortcut tiles such as Recent Tasks, Screen Rotation, Ventilate and Screen OFF that can be dragged into the bottom bar. — The customisation screen now has a Reset button to restore the default navigation bar.

Head-unit System → Version page with Version update (Upgrade), Version Details (View), Restore settings (Reset) and Factory Reset (Reset), and the build number 13.1.33.2510254.1 shown on the right. — “Restore settings” is the reset that now leaves Bluetooth switched on.

What we have not verified#

This is a translation of BYD Austria’s bulletin, not a test: we have not installed V2.1.0 on a Atto 3.
The bulletin was published by BYD’s Austrian importer. The release itself is the European one, but roll-out dates are given for Austria, and a few items are country-specific (radio services, interface languages, legal notes).
Availability of individual features can depend on trim, model year and the head-unit hardware.
