Geely-owned Chinese brand Zeekr made headlines last year when it unveiled its Golden battery, touted as the fastest-charging battery in the world. The lithium-iron-phosphate (LFP) pack with prismatic cells was said to be capable of charging from 10-80% in just 10.5 minutes when connected to a powerful charger. The Zeekr 7X SUV, equipped with the Golden battery, recently surpassed expectations in a real-world charging test, confirming the brand’s claims.
China, unlike the U.S., has embraced electrification wholeheartedly and is leading the way in transitioning away from gas-powered vehicles. Geely Group’s Zeekr brand is at the forefront of this revolution, producing high-tech EVs like the 001 crossover, 007 sedan, and 009 MPV. Zeekr is also a major player in the battery and charging technology space, with many of its EVs built on the Sustainable Experience Architecture (SEA) shared with other Geely Group brands like Volvo and Polestar.
The Golden battery developed by Zeekr supports a 5.5 C-rate, allowing it to charge or discharge at 5.5 times its total capacity per hour. This exceptional charging capability means that the battery can charge from 10-80% in just 10.5 minutes, setting a new standard for fast-charging EV batteries.
To put the Golden battery to the test, Kyle Conner, from InsideEVs and Out Of Spec Reviews, recently conducted a charging test on a Zeekr 7X SUV in China. The results were astonishing, with the 75-kilowatt-hour LFP battery delivering an impressive 615 kilometers (382 miles) of range on the CLTC cycle.
Conner depleted the battery to 0% and then plugged it into a Zeekr-owned charging station rated at 840 kilowatts. Unlike traditional nickel-manganese-cobalt (NMC) batteries, which peak early in the charging cycle and taper off, LFP batteries like the one in the 7X maintain a consistent charging curve throughout the process.
During the test, the 7X displayed a peak charging rate of 460 kW, exceeding 300 amps of current flow and over 600V of voltage at just 3% state-of-charge. The charging rate continued to increase, hitting a peak of 460 kW before stabilizing at around 400 kW as the battery neared full capacity.
The Zeekr 7X’s performance in the real-world charging test showcases the potential of the Golden battery and highlights Zeekr’s commitment to pushing the boundaries of EV technology. With fast-charging capabilities like these, Zeekr is setting a new standard for the industry and solidifying its position as a leader in the EV market.
