HOW TO RUIN YOUR ELECTRIC CAR'S BATTERY - LFP EDITION

EV Channels Review

This video delves into the nuances of Lithium Iron Phosphate (LFP) battery care in electric vehicles, contrasting manufacturer recommendations with recent research. The presenter highlights that while Ford and Tesla suggest charging to 100% regularly for calibration and range accuracy, a new study indicates that operating within lower state-of-charge ranges (e.g., 0-60%) is more beneficial for long-term battery longevity. The core conflict arises because frequent high-state-of-charge cycling, especially above 75%, accelerates degradation by consuming lithium inventory. The video explains the voltage curve differences between LFP and NMC batteries, clarifying why LFP needs periodic full charges for accurate state-of-charge reporting. It concludes that for optimal longevity, minimizing time spent at high states of charge is key, suggesting that charging only when needed, rather than leaving the car plugged in constantly, might be preferable for LFP batteries, especially for those without home charging. However, the presenter cautions that these are best practices for longevity alone and don't negate the practical advice of keeping the car charged for emergencies or the risk of permanent damage from deep discharges.
