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
- Usable SoC = 90%
- 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.

- nominal voltage =723 V
- capacity = 129.2 Ah
- voltage range = 610 V to 834 V
- weight [kg] =630kg
- cells = 355kg
- cell to pack mass ratio = 56%
- number of cells = 396
- charge time = 5% to 80% in 22.5 minutes
- 270kW peak charge power
- modules: 33 modules with 12 cells in each module
- L: 390mm
- W: 150mm
- H: 110mm
- Mass: 12kg
- cooling system
- water-glycol system that can heat and cool the battery
- cooling system sits under the main battery structural tub ensuring any coolant leaks cannot enter the pack
- heat pump based system that allows heat from HV components to be stored in the battery pack
- cell target temperature is changed based on driving style selection
- battery is preconditioned to a certain temperature level when the vehicle is connected to the mains for charging


- cell make and model
- LG Chem E66a
- Pouch cell format
- NMC712

- Gravimetric power density, pack = 730 W/kg10s
- Volumetric power density, pack = W/litre10s
- Estimated cost = $/kWh
- Cell to Pack mass ratio = 56%
- Cell to Pack volume ratio
Other key features:
- Safety
- BMS
- master and slave architecture
- HV Distribution
- HV and LV Connections
- Cooling Connections
- Mechanics
- located in the underbody of the Taycan to ensure a low centre of gravity
- battery housing is a load-bearing component of the body structure
- truss-design battery frame with multiple subdivisions
- 28 bolts fix the battery to the body structure
- battery contributes ~10% of the vehicle’s overall stiffness
- cooling elements are glued on underneath the bulkhead plate using heat conductive adhesive
- steel protective lower bashplate
- aluminium battery frame design
- MIG welded battery frame
- laser welded bulkhead and protection plates

- Sealing
- waterproof housing is a sandwich construction consisting of a cover at the top and a bulkhead plate at the bottom
- note: the cooling system sits under the battery pack housing thus ensuring coolant leaks cannot short the HV system
- Venting strategy
- Durability
- Availability
- Recycling
- Shipping
- Warranty
- 60,000 km or three years if following conditions:
- Vehicles standing longer than two weeks supposed to be connected to a charger
