Zeekr, an electric vehicle (EV) manufacturer within the Geely Auto group, has integrated its proprietary fast-charging battery technology, based on lithium iron phosphate (LFP) chemistry, into its latest vehicles.
Zeekr introduced its so-called “Golden Battery” in December, touting fast-charging capabilities made possible by a prismatic internal design.
According to the company, the 75 kWh battery pack supports ‘5.5C ultra-fast charging’, allowing vehicles to be charged from 10% to 80% in just 10.5 minutes using 800V charging at Zeekr’s own stations.
Zeekr claims that the new sedan, with a revised battery management system to enable faster charging, offers a range of 682 kilometers based on Chinese standards. 10.5 minutes of charging adds 482 kilometers, and 5 minutes of charging adds 265 kilometers.
If these claims are true, Zeekr’s battery technology will provide the fastest charging speeds for mass-produced lithium ternary batteries worldwide, surpassing the more expensive nickel-cobalt-manganese chemistries.
In December, Zeekr said: “Traditionally, LFP batteries have been considered by the industry to have lower energy density compared to nickel-manganese-cobalt (NMC) batteries at the cell level. To address that, ZEEKR engineers carefully designed the battery pack for the new LFP to achieve high energy density at the pack level. Thanks to the application of newly developed materials and a simplified structural design, the volume utilization of the new battery pack reaches 83.7%, higher than many comparable competitors worldwide.”
