EV Home Charging - Charging to 80% Maximum State of Charge If you have been around the EV community long enough, you have probably heard the advice to keep you battery's state-of-charge (SOC) below a certain level if you don't need the range for a road trip.  The number quoted is often 80%. Keeping the SOC of a lithium-ion battery above a certain point for long periods of time, particularly in the heat, has been shown to accelerate early degradation of the battery capacity.  There are scholarly articles to dive into the details such as this one from .   I encountered the two-dimensional temperature - SOC plot on David Laur's  David Laur's blog  that focuses on life with a Nissan LEAF.  The purpose is to communicate the best combination of temperature and SOC to maximize battery longevity in the LEAF's passively-cooled battery pack.  In Dave's words:  "Now, we all know Nissan put the fear of God into us when charging
