Yes absolutely. Batteries have a sweet spot. Below that the amount they can discharge decreases first slowly, then rapidly with temperature. But there are also idiosyncrasies with the way the API backend calculates charge. Remember, WattCat only reports what comes through the JLR software black box, which is probably broken in places.I have a question regarding how temperature affects battery energy as measured in kWh. I left the house this morning with WattCat reporting 40.5 kWh and came home after a 6.5 mile drive with 43.95 kWh showing - a gain of nearly 3.5 kWh. The ambient temperature was 20 deg F warmer (50 deg F) than the previous 10 days or so. Can warmer temps account for the significant "gain" in kWh as energy is denser in warmer environments? Thanks!
