<Answer to...Greetings all, We have notice a degrading of miles when charging lately. My daughter drives 170 miles round trip (4 days a week) traveling between the university n home. Until lately when charging to 80%. We we're getting 200 miles per charge to 80%. Lately when charging to 80%, we are getting between 175 n 178 miles. That's a difference between 22 n 25 miles less. We recently complete a 100% charge which gave us 225 miles. When we first get the ID a 100% gave us 260 miles. Has anyone been experiencing this type of behavior?> There are several EV charging studies online now, many posted on LinkedIn, stating that while Lithium Ion battery packs do not have "memory" capacity loss issues like NiCad batteries, they do "learn" how they are used, adjusting what they make available to the EV based on driving and charging activities. We discovered that it is best to occasionally draw the battery pack down to a low level (10-15% State of Charge for example), then recharge to 100%. Here is the link for the latest article on this charging technique: https://lnkd.in/gTTp2HYK I hope this helps your range problem.
