A residual range indicator device for a storage battery-powered electric vehicle, comprising a processor unit connected to a memory unit and to a display device, in which the indicator device is further connected to a device for measuring the distance travelled by the electric vehicle and to a device for measuring the charge present in the storage batteries, the memory unit containing data relative to the electrical-charge consumption of the vehicle as a function of the distance travelled, as a function of the type of route and as a function of other operating parameters, the processor unit executing a control programme comprising the following functions: identifying, on the basis of the measurements made by the travelled distance measuring device and by the charge measuring device, the type of route travelled by the electric vehicle; and calculating, on the basis of the data contained in the memory unit, the distance which the electric vehicle is still able to travel. <IMAGE> |
