How does MyPermobil estimate how far I can travel?

Permobil uses an exclusive advanced calculation method to estimate battery charge and travel distances. Battery range estimates are provided in both hours & distances and updated approximately every 5-10 minutes within the app. Please note travel distances are estimates only and are based on the original battery type and model ordered. Factors such as user weight, extra carrying load, ambient temperature, terrain, inclines and driving behavior may impact accuracy of estimates.
