Simple tips for long battery life
As the heart of the electric car, our high-voltage batteries are designed through and through for premium quality, safety and a long service life. Over the runtime, however, normal aging processes reduce the battery capacity – the amount of energy that can be stored. The good news is: your charging and usage behavior has an impact on battery life and with a few simple basic rules in daily use, you can maintain battery capacity for a long time. The original range is preserved for a long time and you are actively doing something about the loss of value of your electric car.
Three basic rules
For a longer battery life.
- Do you mainly drive short distances? Audi recommends charging up to 80% for daily use.
- Would you like to drive long distances? To reach the maximum range, like to charge your Audi to 100% and drive off as directly as possible. However, if you regularly charge your Audi to 100% in deviation from rule 1, the aging process of the battery will be accelerated and the usable battery capacity will decrease comparatively faster.
- Do you have longer service lives? When parking the vehicle, pay attention to a charge level between 30% and 80%.

Charging destination setting In the myAudi app and in your vehicle, you can easily define a limit for the maximum battery charge. So you don't have to worry about anything else. |
Configuration to 80% |
Before long-distance journeys, Audi recommends setting the charging destination to 100% in order to achieve the longest possible range. |
Charging timer With the charging timer you set the exact time of departure. Directly in the vehicle or conveniently via myAudi app. This means that the automated charging process with a pre-set battery level is as close as possible to the departure time. In addition, the preconditioning air-conditioning of the vehicle interior before departure to the desired temperature. |

Set departure time to avoid downtime with a full battery |
Route planning Plan your route with the e-tron route planner before you start your journey: The route takes into account your individual range and provides appropriate charging stations for you. |

Driving mode |
The "efficiency" driving mode leads to lower energy consumption through an efficient driving style. This reduces the electrical and thermal battery load. This preserves the battery capacity. | |
Charging tips
- Fast charging (High Power Charging > 100 kW) is mainly recommended for long distance, not for daily use.
- With High Power Charging, the charging speed slows down as the state of charge of the high-voltage battery increases. Therefore, a full charge of the high-voltage battery can extend the total journey time. The e-tron Route Planner supports you with optimal charge planning.
- To keep charging times low on a long-distance trip, the e-tron Route Planner falls back on the full battery capacity if necessary and recommends a charge above 80 %. After a long-distance journey, set your charging target back to 80 % for your daily journeys.
- When using the e-tron Route Planner with the Audi e-tron GT, the temperature of the high-voltage battery is preconditioned for fast charging in order to achieve the maximum charging speed.
Battery protection
included buffers provide additional protection for your high-voltage battery against unintentional, damaging overcharging and deep discharging.

Battery
The capacity of the high-voltage battery of an electrically powered vehicle is divided into gross and net capacity. The gross capacity describes the entire physical capacity of the high-voltage battery. However, to protect against self-discharge, to increase the service life and to ensure the emergency start reserve, the theoretically available energy content is technically limited. This actually usable energy content is called net capacity.
