"Charging from 10 to 98 percent took just six minutes and 27 seconds. The more standard 10-80 percent time takes just three minutes, 44 seconds. Only have a minute to plug in? Still sufficient to get from 10 to 35 percent state of charge."
"Even at -22 F (-30 C), the Shenxing battery charged from 10 to 98 percent in 9 minutes. That's as long as BYD's Blade 2.0 takes to charge to 98 percent at room temperature."
"CATL credits its battery's cold-weather performance to very precise temperature control of the individual cells and an ability to heat itself in pulses. An extremely low internal resistance of just 0.25 milliohms also plays an important role."
"After 1,000 fast charges, the battery should retain more than 90 percent of its original state of charge, the company said."
LFP batteries exhibit more linear charging curves than NCM batteries and can be fully recharged quickly using DC fast chargers. Charging from 10 to 98 percent takes just over six minutes. Cold-weather performance is a concern for EVs, but the Shenxing battery charges efficiently even at -22 F. CATL's battery technology includes precise temperature control and low internal resistance, contributing to its performance. After 1,000 fast charges, the battery retains over 90 percent of its original state of charge.
