Zeekr 007 LFP

Zeekr 007 Golden Brick Battery

The Zeekr 007 LFP battery is also described as the “Golden Brick Battery” pack.

It appears the gold colour comes from a wrap that is used to electrically isolate the pack. That sounds very much like Kapton tape.

Specifications

Metrics

  • Pack energy density = 128.4Wh/kg
  • Cell to pack volume ration = 83.7%
  • Pack energy = 75.6kWh
  • Nominal voltage = 614.4V
  • Nominal capacity = 124Ah
  • Configuration
    • 192s 1p
  • IP rating = 8 assume that means 68
  • Pack mass = 589kg +/-17kg [6]
  • Peak discharge
    • 344kW (RWD)
    • 528kW (AWD)
    • Peak discharge = 16C

These numbers are based on images, a few data points and a few assumptions. Please treat these as estimates at this point. The RWD Zeekr 007 with the LFP battery has a quoted power output of 310kW, we assume 90% efficiency for the motor and inverter, hence 344kW peak battery output. The AWD version has a peak power of 475kW and hence at 90% efficiency 528kW at the battery.

The appears to be a coolant inlet and outlet shown at the bootom of the above image. However, the exploded view doesn’t show the cooling system.

The image below (from the YouTube video) shows the coolant connections on the rear of the pack (our assumption is that the front is tapered).

What appears as the application of thermal interface material to the coolant plate [5] shows the cells are cooled on the bottom edge.

Charging

  • Peak charge power = 500kW
  • Maximum charge rate = 4.5C
  • 10 to 80% < 15 minutes
    • this is equal to 500km of range added to the Zeekr 007

The leaked youtube video [3] of the LFP pack charging shows it peaking at ~390kW.

They state: “At -10 °C, the fast charging speed increases by 25%”. This is difficult to interpret at this point in time.
