AI Technical Summary
Existing battery-powered electric vehicles require external charging at stations, which is inconvenient and costly, and there is a need for an alternative method to ensure continuous operation without such external charging.
The propeller shaft of the electric vehicle drives alternators via belts to charge the vehicle batteries, eliminating the need for external charging stations.
Enables continuous operation of the vehicle without the need for external charging, reducing costs and eliminating waiting times at charging stations.

Abstract
Description
[0001] In a battery-powered electric vehicle, the rotation of the propeller shaft is used to drive several alternators via belts installed between the propeller shaft and the alternators. The alternators are located on the underbody of the electric vehicle. These alternators charge the vehicle batteries.
[0002] Advantages: External charging at charging stations is no longer necessary, thus ensuring endless driving.
[0003] Price savings, as external charging at charging stations is no longer necessary.
[0004] No annoying waiting at gas stations. Explanation of figures 1 cardan shaft 2 vehicle rear axle 3 power cables 4 power cables 5 Battery 6 Motor vehicle front axle 7 belts 8 Automotive alternator
Claims
[1] An electric vehicle is characterized by the rotation of the cardan shaft, which drives belts (connected to the cardan shaft) for several alternators, so that the vehicle batteries are charged by means of power cables from the alternators. This eliminates the need for external charging at the power station.
