Hello, i have noticed that the battery temperature has always been above medium, even in the morning when i start the car for the first time, without having charged overnight.
I never use fast chargers.
Is it normal, how are yours?

Mine always ran about 3/4 toward hot. The problem I had with battery temp is that in hot weather it would run excessively hot and you don’t get a warning until you turn the car off. At that point you have to manually start the cooler which uses the AC compressor to run the cooler and they want you to plug in to conserve the charge. It got so bad I sold the car. Mazda designed it that way according to tech line.

Gary will probably explain better but basically on excessive battery temperature a warning light comes on. It advises you to stop and manually start the battery cooler. The start cooler option only appears when the battery excessive temp warning comes on. Mazda also advise you to plug in and charge because the heatpump, which cools the battery cooling liquid, draws directly from the hv batteries and there reduces range unless you balance it with an active charge.

It is not a start/stop setting option so you cannot force

I had a Mazda tech get online with the factory tech line and ask two questions. First why isn’t it automatic and 2nd can I turn it on manually without getting the warning. They said they intentionally programmed it this way because they don’t know how much battery you have left or how far you are from a charger. On the second question is no you can turn it in until the warning comes up and that doesn’t happen until the battery hits 104 degrees. That means you could be driving all day in the heat and not even know it until you shut off the car. Where I live we will have 60 plus days of over 100 degrees during the summer. It got to the point that it happened twice a day every day. I told Mazda it was a bad design and I wanted to return it under the lemon law. I even had a lawyer working on it and Mazda declined because the car was working as designed. The lawyer said to take it any further I would have to sue Mazda. They have more lawyers and money than me so I sold it back to the dealer at a loss. I have had 4 Mazdas but this will be my last

I'm sad about what happened to you, now i'm also apprehensive about what the future holds for my car.
Thanks for your feedback.
