    Parked the car for 40mins, the temperature for the hv battery increased from 38c to 48c. Is it because I park it with higher soc(67%)? Cabin temperature is 31c and battery inhale temperature is 33c.

    I don't think it's unusual, expect that 10C is quite a difference. When the car's on there's a fan to dissipate the heat. When you park that fan stops, and no more cabin air circulation either. Are you garage parked as well? Or parking in direct sun?

    This has concerned me as well, might be good if the car's programming could run the fan for a few minutes after shut down, depending on the measured temperatures.
