Great article, but you missed a basic point about charging times, which are adversely affected by ambient temperature. When the ambient outside temperature is below around 5c and the battery is cool [ not driven for a while]., part of your charging electricity is used to fund electrical power to a heater. Inevitably, this will slow your charge times down [ not your charger]. In situations where the the battery temperature is in excess of 35-45c [dependent on chemistry] you will also experience extended times due to battery cooling taking place. Lithium ion technology is complex and very temperature volatile, when driving and charging the Battery system will require constant heating and cooling.

As you said, Perry, Lithium Ion technology is complex. We wanted to keep the baseline for this piece basic to give room to establish some of the principles of EV charging.

You are absolutely right, temperature does impact charging times, with some of the energy distributed to the vehicle used to prepare the battery rather than be stored in it.

Would you be interested in doing a follow up piece for us to explain some of the more complex principles in battery charging?
