The development of the battery electric vehicle is motivated by the reduction of the CO2 emissions. Therefore, it is important to understand the main CO2 contributors during the life cycle of the vehicle. The Life Cycle Assessment of the Taycan confirmed that the battery is responsible for about 40% of the CO2 emissions during the production of the vehicle. This insight leads to the question of the optimal battery size – to meet the customer’s needs and the environmental targets. By analyzing customers preferences and use cases, Porsche reinforced following presumptions as an important indication for rightsizing the battery.:

    The majority of daily driving distance is less than 80 km.

    About 80% of weekly driving distance is less than 450 km.

    For long distance travel the customer focuses on traveling time (driving and charging).

    Driving Dynamics is an important criterion for Porsche’s customers.

    Green charging energy and optimization of supply chain are main CO2 reduction potentials today

    New cell technologies, higher charging power and increasing recycling ratios are CO2 reduction potentials of the future

    In the presentation, we describe how CO2 emissions can be reduced while considering customer needs. Beside using green energy (CO2-neutral) for production and in use charging the battery size/capacity is an important factor affecting CO2 and other environmental factors.

    Considering the main factors “CO2”, “traveling time” and “driving dynamics” a limitation of battery capacity in combination with fast charging is possible. In order to achieve our Vision of “Net Zero CO2 by 2030” of course recycling is a key success factor.
