2020 Rimac Nevera

The 2020 Rimac Nevera is a tour de force as an electric vehicle.

The all-electric Rimac Nevera is officially the ultimate record-breaking hypercar, setting a new 0-400-0 km/h (0-249-0 mph) benchmark on the same day that it set another 22 acceleration and braking records.

The form of this battery is complex, however, this is a hypercar that can afford an expensive battery pack design.

  • Usable Energy = 106.8 kWh (120 kWh total)
    • SoC Window = 89%
  • Nominal Voltage ~ 630V
    • Voltage Range = 731V to 435V
  • Nominal Capacity ~ 192Ah
  • Configuration = 174s40p
  • Maximum Power = 1408 kW10s
    • Maximum Regen = 300kW
  • Pack Mass = 727 kg
    • Cell Mass = 487.2 kg
    • Pack-Cells = 239.8 kg
    • Cell to Pack Ratio = 67%

Pack Mass: Rimac claim that the cell to pack mass ratio of the Nevera is 67% [1]. They also state that it uses 6960 21700 cells and we know that these weigh 70g each +/-1g. Hence we have total cell mass = 6960 x 0.07 = 487.2 kg and knowing the 67% cell to pack ratio we then have a pack mass = 487.2 / 0.67 = 727 kg

Cooling

  • Liquid Cooling
  • Flow rate = 60 litres/minute
  • Cooling plates are used to cool the top and bottom of the cells [4]

There are a lot of connections in this cooling system both inside and outside the pack.

Charging

  • Maximum charge power = 500 kW

Cell

  • Format = 21700
  • Cell weight = 0.07 kg
  • Capacity ~ 4.79Ah
  • Total number of cells = 6960

  1. I am very much confused looking at Rimac’s numbers. If I am calculating right, 1400KW with 630V of nominal voltage equates to 2200 Amps of current. And with 40p config, its about 50-60Amps max current capability of each cell. Is that understanding correct?
