“If a person would only keep their EV battery topped off, and seldomly or never discharge it down to 15% or less, won’t the battery develop “memory” in a bad way and no longer be able to hold and discharge fully? Or has that issue been solved”
Bro what year are you living in. “Memory effect”
That’s 5 generations of battery tech ago. NIcads had that issue in the 1970s, nickel metal hydride eliminated that in the late 80s. Then lithium ion polymer cells,NMC,LFP,lithium titanium,sodium ion none of the modern cell chemistry have any memory effects they have operating windows measured in SOC and cycle lifetimes measured in SOH. Lithium cells’m like to be 80-20% SOC window, LFP can do 100% to 5% , sodium ion does 100-0 and can be held at zero unlike lithium which would brick it. Aluminum Graphene cells , calcium and magnesium are on the horizon or in use with the DOD in the case of Al-Gr type cells.
Thank you for the update.
