Initial supercharging results suggest that the new lithium iron phosphate (LFP) battery powered Tesla Model 3 can supercharge even faster than the version with the nickel battery. This looks promising, and is not unexpected.
China-based website 42HOW conducted a side-by-side test of the new LFP battery Tesla Model 3 and the regular nickel battery Tesla Model 3.
The supercharging session photos in the above tweet demonstrate that the original nickel-based battery Tesla Model 3 took ~62 minutes to go from 40% to 99% state of charge (SOC), whilst the LFP variant took just ~42 minutes to get from 41% to 99%. Although these SOCs at best represent approximately the “second half” of a typical charging session, the LFP nevertheless would seem to demonstrate a time saving of around 32% or approximately a third.
We can also see that the LFP pack appears to accept higher charging power at a given state of charge. At 40% SOC, the nickel variant is charging at 64 kW, and at 41% SOC, the LFP variant is charging at 69 kW. Whilst we would expect both to charge at much higher rates at around these SOCs on Tesla’s V3 superchargers, this slightly higher charging rate for the LFP is suggestive. Likewise, at 99% SOC, the newer LFP variant is still accepting 9 kW of power and the nickel variant is accepting 4 kW of power.
TESLA – NEW BATTERY UPDATE! – LFP BATTERIES FOR SHANGHAI – FAST SUPERCHARGE?(LITHIUM IRON PHOSPHATE)
Tesla’s Customer Support account on Chinese social media platform Weibo suggests that the LFP batteries used within the Standard Range+ variant of the Model 3 can be charged to 100%, which breaks past narratives that an EV battery should rarely be charged to its full capacity.
When Tesla recently introduced the LFP (lithium iron phosphate) batteries into the made-in-China Model 3 earlier this month, we knew it extended the range of the EV. What we didn’t know is that, unlike the conventional NCA (nickel cobalt aluminum) batteries used before it, you can apparently safely charge it to 100% without harming the lifespan of the battery.
