Does anyone have any information about the Prius Hybrid battery in regards to how it operates in extreme heat and cold (mostly interested in extreme heat)? The temps here in the summer are very high and I notice that when I drive my car in the summer (mostly during the hottest part of the day) after it has been sitting for a while it takes a very long time to act normally. When I say normally, I mean charging when braking/acceleration, going into EV mode when it is supposed to and not running the ICE constantly. For example there are times where my car is sitting for hours the SOC is anywhere from 62-66%. I turn on my car and it starts depleting the battery all the way to the mid 40% in a matter of minutes. Also as I’m driving the engine stays on, does not go into EV mode for like 10 minutes and for the first 5 minutes or so when I brake and accelerate it does not charge the battery…the battery still continues to slowly drop. Another time at work when I got back from lunch I couldn’t find a covered spot so I parked in the sun with visor. A couple hours later I moved my car to a covered spot and I drove literally one minute to get to the covered spot. I had six bars on the battery and it depleted all the way down to two bars.
