Embodiment Construction

[0054] according to figure 1 , the vehicle system consists of a plurality of road vehicles 1 and a plurality of charging stations 2 . Both the number of road vehicles 1 and also the number of charging stations 2 is in principle arbitrary. Furthermore, these two quantities are independent of each other. It is possible that only a single road vehicle 1 , a small number of road vehicles 1 or many road vehicles 1 belong to the system. The number of charging stations 2 can also be varied in a similar manner. Preferably, the road vehicle 1 is a commercial vehicle such as a truck, van, passenger car and the like.

[0055] Only one individual road vehicle 1 and only one individual charging station 2 are explained in greater detail below in conjunction with the further figures. However, this expression also applies to other road vehicles 1 and charging stations 2 not explained in detail.

[0056] The road vehicle 1 is battery-powered. so its - see figure 2 and 3 - there is at ...

Abstract

A battery-powered road vehicle (1) drives towards a charging station (2). The control device (8) arranged on the road vehicle (1) connects the arrangement of the contact device (11) arranged on the road vehicle (1) at the upper side (12) of the road vehicle (1) with the charging station (2) A contact element (10) above a road vehicle (1) makes contact. A control device (8) of the road vehicle (1) transmits a switch-on command (S) wirelessly to a control device (9) arranged at the charging station (2). The control device (9) of the charging station (2) applies a voltage to the contact element (10) based on the switch-on command (S), so that via the contact element (10) of the charging station (2), the contact device ( 11) and the charging converter (14) supply charging current (I) from the AC voltage network (13) to the electrical energy store (6) of the road vehicle (1). The charging converter (14) adjusts the output voltage (U) given by the charging converter (14) and / or charging current (I).

Description

technical field [0001] The invention relates to a charging method for a battery-powered road vehicle. [0002] The invention also relates to a battery-powered road vehicle and a charging station for such a road vehicle. [0003] The invention also relates to a vehicle system consisting of a plurality of battery-powered road vehicles and a plurality of charging stations. Background technique [0004] The concept of "battery drive" is already known in trams and trolleybuses. In trams and trolleybuses, the concept of "battery drive" means that, in the event of a failure of the electrical energy supply - usually via overhead conductors - short distances can be achieved under clearly restricted conditions and over very short distances. Emergency operation of the time, for example to drive the vehicle slowly out of the crossing area. Within the scope of the present invention, however, the term "battery-driven" no longer has this meaning. Rather, it means that, although the roa...
