Important information about all-electric
The ranges determined using the standard WLTP cycle enable comparison between manufacturers. They also include the measuring reach achieved through recuperation (energy recovery during braking). The additionally specified long-distance range provides a guide value for journeys over longer distances. This is based on a partial WLTP cycle that is characteristic of long-distance journeys, allowing for additional auxiliary equipment (e.g. air conditioning). Various factors, such as driving style, traffic situation, topography, speed, use of comfort/auxiliary equipment (e.g. air conditioning, Infotainment, etc.), outside temperature, number of passengers, payload and selected driving mode (e.g. Sport), can have a negative impact on the actual range.
A lithium-ion battery is subject to physical and chemical ageing, as well as wear and tear. This reduces the battery capacity, depending on the usage pattern and environmental conditions, resulting in a reduction in range and an increase in charging times as the battery ages. Due to the effect of temperature on battery and charging performance, as well as battery life, please consider the following when parking, driving and charging your car:
If possible, avoid permanent ambient temperatures of over 30 °C, such as prolonged parking in direct sunlight.
If you cannot avoid ambient temperatures of over 30 °C when stationary, connect the vehicle to the mains supply after use and charge the high-voltage battery with AC (alternating current) to a maximum charge status of 85 %.
If the car is left stationary for more than two weeks, the ambient temperature should, if possible, be between 0 °C and 20 °C and the battery charge status maintained between 20 % and 50 % during this time.
For the shortest possible charging time, a battery temperature of approx. 30 °C to 35 °C is ideal.
If charging the car on a daily basis, the maximum charge status of the high-voltage battery should be set to approx. 80 %.
The specified charging outputs and times are dependent on various factors: in general, the charging output and time can vary due to physical and chemical limits, depending on factors such as the available output of the country-specific energy infrastructure, the customer's own domestic installation, the temperature, interior pre-conditioning and charging status, as well as the age of the battery. Charging times may therefore be significantly higher than those specified. To achieve the optimum value of the specified DC charging time (DC = direct current) for a charge status increase from 5 to 80 %, a CCS (combined charging system) fast-charging pedestal with > 270 kW and > 850 V is required, as well as a battery temperature of 30° - 35 °C. The charging status when commencing charging must not exceed 5 %. The determination of the specified charging time for a WLTP range of 100 km is based on the same prerequisites. For physical and chemical reasons, the charging speed decreases as the battery approaches its full capacity. Therefore, it usually makes sense to use fast DC charging to charge the battery up to 80 % or up to the required range. The predominant use of CCS fast-charging pedestals leads to a long-term increase in charging times. For regular fast DC charging, we recommend a maximum charging output of 50 kW. When charging in a domestic environment, AC charging (AC = alternating current) is recommended. Using an (AC) industrial electrical outlet will result in improved efficiency and a much shorter charging time compared to using a household socket.
In general, the available drive power in battery-operated electric cars depends on various factors, such as the duration of the required performance, as well as the battery voltage and temperature. The specified power is available for at least 10 seconds and the specified overboost with standard launch control for at least 2.5 seconds. Extremely sporty driving or charging at a fast-charging pedestal can result in an increase in battery temperature and, therefore, in temporarily reduced drive power. Due to the physical environment, the maximum power required to achieve the specified acceleration values can be repeatedly produced, but usually not consecutively.
