Software update: Audi gives the e-tron 55 more range free of charge

A little more than a year after the start of production of the Audi e-tron 55 in September 2018, the company carried out a technology update that resulted in an improved range thanks to the higher net capacity of the battery. By means of a software update, Audi is now donating the higher range to the e-tron 55s produced until November 2019.

The first e-trons were produced between September 2018 and November 2019 under the name “e-tron 55 quattro” and came onto the market with a gross battery capacity of 95 kWh, of which 83.6 kWh were net usable. Since November 2019, following a technology update, this model has been marketed with 86.5 kWh of usable battery capacity for a range of up to 436 km – around 25 km more than before the changeover. In the current model year, Audi is currently advertising up to 441 km.

Software update for 20 km more range

Before the update mentioned, e-tron 55s now also have an increased range via software updates. With the update, Audi is also releasing a net usable battery capacity of 86.5 kWh for the models produced up to November 2019. According to the manufacturer, the plus of 2.9 kWh should provide an additional range of up to 20 km in real driving.

However, the update is not over the air, i.e. via OTA update via WLAN or cellular network and thus can be carried out by the owner himself. The update is now available for installation free of charge from Audi service companies, explains the manufacturer.

Optimizations for the front electric motor and cooling

The larger usable battery capacity is only part of the update, the control of the front electric motor has also been optimized. In normal driving mode, the motor on the rear axle provides propulsion as standard. For improved efficiency, the front electric motor is now almost completely decoupled and de-energized. Both motors are only used when more power is required.

In addition, Audi lists improvements for the cooling. The thermal management, which consists of four separate circuits, now temperature the high-voltage components more efficiently. Thanks to an adapted control, the volume flows in the coolant circuit could be reduced, so that the energy consumption is reduced, according to today’s announcement.
