What maintenance is required for the electric motor in an Audi A2?

I want to ensure the longevity of my Audi A2's electric motor. What kind of maintenance is recommended and at what intervals?

Regularly check and replace the electric motor's brushes every 30,000 miles or 2 years to prevent loss of power and potential damage.

Make sure to keep the electric motor's cooling system clean and well-maintained to prevent overheating and potential damage. This includes regularly checking and replacing coolant as needed.

To preserve the electric motor's battery life, avoid constantly charging it to 100%. Instead, aim for a charge level between 30-80% and occasionally fully charge for battery health.
