A closer look at energy consumption in EVs

When it comes to factors that affect energy consumption in EVs, the big kahunas are weight and wind resistance (aka CdA), but there are other factors that can have a surprisingly outsized effect and that tend to be overlooked, such as the use of climate control (AC, of course, but especially heat). Conversely, one factor… Read more »

The Goldilocks zone: Calienté explains that battery pack heating is just as important as cooling

In the eyes of an EV driver, the success of the battery is measured in a completely binary way: does the battery last the life of the vehicle, or not? In fact, the best praise you can give any battery – whether in your laptop, phone, or EV – is not to have to think… Read more »
