It seems like the Volt/Bolt and all the Teslas can handle hot better than a Toyota/Lexus hybrid or the Leaf can - GM and Tesla use liquid cooling to manage temperatures within the pack. Toyota is all aircooled, and the only time you really hear the battery blower fan kick on is when the pack fails and codes are thrown. Honda in their first 2 generation of hybrids had very little cooling.
There have been stories of Volts still on the original battery packs, while a Prius will need one after the 160K mark - when it will it happen is dependent on where the car is operated and how it's operated(as a normal car vs. being used as an Uber or cab).
