Sorry, no but it's easy to see for yourself. L2 charge for an hour or more even in a cool environment in the shade (e.g. concrete parking structure) or at night. While charging or shortly after it's stopped, open the hood and notice the whole PDM stack is warm (not quite hot) and warmer than body temperature and ambient temp.lorenfb wrote:So you have been actually taking temperature measurements while L2 charging?cwerdna wrote: Just L2 charge for at least an hour and the whole PDM stack gets pretty warm. And, it gets a bit warm near the inlet, as well.
You'll also notice warmth around the inlet area.
Yes. Circulating coolant heated by the on-board charger would almost certainly heat the battery pack in many/most cases.lorenfb wrote:Are you inferring that's a factor for Nissan's not using part of the cooling system to also cool the battery?cwerdna wrote: You wouldn't want to dump that warm coolant into the battery pack except when the pack's too cold.
Except during hot summer days, it's rare for my '13 battery pack to hit 90 F or higher, esp. given my car has no CHAdeMO. L2 charging from say 30-ish% to 80% on my '13 Leaf doesn't heat the battery much, only a few degrees F.
