I have to work with electric vehicles 24 hours a day. Can I give an electric vehicle with removable batteries? Can I change the battery of an electric vehicle in 5 minutes?

Electric vehicles with external battery pack
 
In case of particularly hard uses, Alkè electric vans (the ATX 200ERb 280E) can have an external battery pack.
external battery packThe set of drive batteries is complete with removable tank and external battery-charger.
The battery pack of this electric van can be replaced in a few minutes and in a very simple way, so the electric van is able to work 24 hours a day without any period of downtime.
Please note that the Alkè electric vans have an autonomy of 70-90km which corresponds to an entire working day.
