How do you calibrate the LFP (Blade) battery of the BYD Atto 3?

Charge the car to 100% periodically (every 1 or 2 weeks) and leave it plugged in for an additional period to allow the charger to balance cell voltages and calibrate the BMS (Battery Management System). This prevents erratic autonomy readings and sudden drops.

What is the battery capacity of the BYD Atto 3?

The BYD Atto 3 features the Blade Battery (Lithium Iron Phosphate or LFP chemistry) with a gross capacity of 60.48 kWh, of which approximately 58 kWh is actual usable capacity for traction and driving.

What is the real highway consumption and range of the BYD Atto 3?

At a constant speed of 120 km/h on the highway under mild weather conditions, average consumption is around 18-20 kWh/100km, offering a real range per charge of between 280 and 300 km.

How does heating (heat pump vs PTC) affect the range of the BYD Atto 3?

Heat pump-equipped versions consume significantly less energy in winter (between -5°C and 10°C), saving up to 15-20% of range compared to models equipped with classic resistance heating (PTC).

What is the SOH of the Atto 3 battery and how is it measured?

SOH (State of Health) measures the percentage of residual battery capacity compared to its factory condition. It is measured by reading internal data via an OBDII connector and diagnostic software.

Battery Conservation Tips

App queries while parked (High drain)

Opening the app with the car off wakes up the 12V systems for 2 minutes at 8-10A with no active charging. Avoid frequent queries if the car is parked for days.

Remote Preconditioning (Safe)

Turning on the A/C from the app engages the high-voltage (400V) battery and the DC-DC converter, charging the 12V battery instead of depleting it.

Queries while driving (Zero impact)

Consulting the app while driving or in READY mode has no effect on the 12V battery as the DC-DC converter powers all vehicle electronics.
