The battery: Sophisticated thermal management, 800-volt system voltage

The Performance Battery Plus is located in the underbody of the Taycan, ensuring a low centre of gravity and thus sporty driving characteristics. The battery housing is a load-bearing component of the body structure, accommodating cooling and electronic components and protecting them from environmental influences.

The waterproof housing is a sandwich construction consisting of a cover at the top and a bulkhead plate at the bottom. The truss-design battery frame with multiple subdivisions is mounted in between. The cooling elements are glued on underneath the bulkhead plate. The battery housing is secured by means of a steel protective plate. For the battery frame, the developers opted for a lightweight aluminium design. On the one hand, this provides a lot of installation space for the cell modules - and consequently a high battery capacity. On the other hand, this has made it possible for the vehicle weight to be kept low. Modern joining techniques are used such as MIG welding (metal welding with inert gases) on the battery frame, laser welding on the bulkhead and protection plates and heat-conducting adhesive on the line system under the battery (see below).

800-volt system voltage: Less weight, faster charging

The Taycan is the first production vehicle with a system voltage of 800 volts instead of the usual 400 volts for electric cars. This enables consistent high performance, reduces the charging time and decreases the weight and installation space of the cabling.

The two-tier Performance Battery Plus used in the Taycan Turbo S and Taycan Turbo contains 33 cell modules consisting of 12 individual cells each (396 in total). The total capacity is 93.4 kWh. The cells themselves are so-called pouch cells. In this cell type, the stack of electrodes is not enclosed by a rigid housing, but by a flexible composite foil. This allows optimal use to be made of the rectangular space available for the battery and a reduction in weight.

The modules each have an internal control unit for monitoring voltage and temperature and are connected to each other via busbars. The foot garages – recesses in the battery in the rear footwell – provide the best possible seating comfort in the rear and allow the low vehicle height typical of sports cars.

Heat pump permits intelligent functions

The battery is integrated into the vehicle's cooling circuit via a line system and a coolant pump. It can be cooled or heated so that it always operates in an ideal temperature window. The cooling elements have been placed outside the actual battery box and are glued to its underside so as to allow heat transfer. The fundamental development aim was to dissipate as little heat as possible into the environment and thus be as energy-efficient as possible in winter.

The battery can also store the waste heat from the liquid-cooled high-voltage components. As a result, it serves as a thermal storage device or buffer, which permits intelligent functions such as conditioning to ensure driving performance: the target temperature of the battery is determined on the basis of the battery charge and the selected driving program. This ensures sporty driving performance and allows Launch Control to be used.

Depending on the outside temperature, the battery is preconditioned to a certain temperature level when the vehicle is connected to the mains for charging. The interior can be preconditioned independently of the mains.

The vehicle also predicts the electrical power consumption of the air-conditioning system and the conditioning of the components based on the outside temperature, humidity and sunshine, as well as the currently selected driving program and the respective setting of the automatic climate control system. The current range is calculated using these figures. In a parallel process, PIRM (Porsche Intelligent Range Manager) provides a background forecast for the other driving programs. When route guidance is activated, if the range calculation shows that the destination can be reached with a low battery charge, the system switches to a more energy-efficient driving programme and a different climate control mode.
