Model 3 and Model Y remain the efficiency leaders, while Model X and Cybertruck show higher Wh/mile as expected.

Tesla can use the motor to warm the battery itself. In this case, about 4% of the battery was used just to raise battery temperature. Tesla does this to protect the battery. So if you ever notice a small battery drop without driving, it’s not a problem. It’s simply the car taking care of its battery.

When comparing Tesla charging data, an interesting pattern appears. Under similar charging currents, NCM batteries heat up more, while LFP batteries stay noticeably cooler. At first glance, this looks counter-intuitive. LFP chemistry is well known for being more thermally robust.

Model Y: In this graph, the battery heater does not activate. The temperature rise is gradual and caused only by the thermal load from...
