The Winter Freeze: Real-World Range Degradation in Pre-Owned 2024 EVs (LFP vs. NMC)
By early 2026, the “great battery split” of 2024 has become a major talking point in the pre-owned market. If you are shopping for a two-year-old EV today, you aren’t just choosing between brands; you are choosing between chemistries. The 2024 model year saw a massive surge in Lithium Iron Phosphate (LFP) batteries in entry-level trims (like the Tesla Model 3 RWD) and Nickel Manganese Cobalt (NMC) in long-range variants.
As these cars face their second or third winter, real-world telemetry has revealed a stark contrast in how they handle the “Big Freeze.”
1. The Chemistry of Cold: Why Ions Slow Down
At a molecular level, temperature is simply a measure of kinetic energy. When the mercury drops below $0^{\circ}\text{C}$, the electrolyte inside a battery becomes more viscous—essentially “thicker”—making it harder for lithium ions to move between the anode and cathode.
