2019 Porsche Taycan

The 2019 Porsche Taycan comes with a total/gross 79.2kWh or 93.4kWh battery pack

Turbo S Performance Battery Plus

This is the largest battery capacity on offer in 2019 and the highest power.

Specifications:

  • total energy = 93.4kWh
  • usable energy = 83.7kWh
  • peak discharge power
    • 460kW10s
  • continuous power = 270kW

The 270kW continuous discharge power is based on the charge power and hence the overall system thermal and electrical limits for extended current demand and heating.
