#BatterySOH #Degradation #Cycles Before purchasing an #electric #vehicle, all eyes are on the #battery: Among first questions concerning #range #anxiety and #charging #speed, most people ask how much #loss of #capacity the battery will suffer over its average useful #life. In this podcast, we talk about (the very normal) #degradation of #batteries, #state #of #health (#SOH) measurements and the research of #predicting a battery's #lifetime. Subscribe to our #Battery Generation #Podcast: https://batterygeneration.podigee.io Follow-up Podcast with Prof. David Howey: • How to prolong a battery's lifetime - Prof... Our podcast guest for this episode is Prof. #David #Howey. He is a British Professor of #Engineering #Science at the #University of #Oxford and holds a Tutorial Fellow at St #Hilda’s #College. His research is focused on #modelling and #managing #energy #storage #systems, for #electric #vehicles as well as #grid and off-grid #power #systems. Battery state of health (SOH) is a measurement that indicates the level of #degradation and remaining #capacity of the #battery. Expressed in a simple way, it describes the difference between the health of a new #battery and the #health of a used #battery. Typically, this is represented as a percentage of its initial #capacity and #performance. According to Prof. Howey's expectations, most #EV #batteries are projected to last hundreds of #charging #cycles (most LiBs) without a noticeable loss in SOH. However, EV batteries do #age over time even if the battery isn't used at all. Apparently, there are always minor losses in battery #capacity: Especially #fast #charging does #harm the #battery in case of a #bad #thermal #battery #management. At higher #temperatures, one of the effects on lithium-ion batteries' is greater #charging #performance & #lower #degradation. That's why many EVs heat their #batteries up before #charging them at #higher #speeds. In winter times, when temperatures are low outside, this can get quite #important when looking at a #high #life-#expectancy of an EV's #battery. https://www.hiu-batteries.de/en/ https://www.celest.de/en/
