I could feel the heat coming off it when I stood next to the repaved section. They didn’t repave the parking area at the edge. Opened to traffic again, seems firm enough to drive on at 160⁰F.

    Based on the image they shared, the heat goes into the refrigerant, which then goes to a radiator to transfer into the outside air.

    It doesn’t use outside air in the sense that the battery doesn’t transfer heat directly to the outside air. There’s the refrigerant between the two.

      Right, that’s what I’m getting at. The heat indeed gets transfered to the outside air.

        It makes more sense if you read the context. They’re responding to a comment that said this:

        I guess you don’t understand active cooling then. If the coolest air in front of you is ~160⁰F, well that’s the coolest your batteries are gonna get, at best. Which is way hotter than rated temperatures for lithium batteries…

        A response that says “it’s not X” can be interpreted as “it’s not doing the thing you said it’s doing”. In this case, over_clox is saying that heat transfers directly from the battery to the air.
