## Abstract

A charge visual display for electric vehicles, of including a plate-like body configured to be fixed to a lower central area area of a rear window of a motor vehicle and bearing—on an exposed surface thereof—a central luminous indicator, a first annular luminous indicator surrounding the central luminous indicator and a second annular luminous indicator concentrically surrounding the first annular luminous indicator.

## Claims

### Claim 1

Charge visual display for electric vehicles, comprising a plate-like body configured to be secured at a lower central area of a rear window of a motor vehicle with a front surface thereof exposed bearing:
a central luminous indicator,
a first annular luminous indicator surrounding the central luminous indicator,
a second annular luminous indicator concentrically surrounding the first annular luminous indicator,
the arrangement being operatively configured in a manner such that, starting from an inoperative condition in which all the luminous indicators are switched off, activation of the charge visual display provides for the following sequence:
flashing or fixed lighting of the central luminous indicator,
at the start of a charging cycle, full fixed lighting of the first annular luminous indicator and partial lighting of the second annular luminous indicator in a minimum lighting configuration,
during the charging cycle, progressive lighting up of the second annular luminous indicator from said minimum lighting configuration towards a maximum lighting configuration,
upon completion of the charging cycle, full fixed lighting of the second annular luminous indicator.

### Claim 2 (depends on 1)

Charge visual display according to claim 1, wherein the progressive lighting up of the second annular luminous indicator is carried out in incremental static steps.

### Claim 3 (depends on 1)

Charge visual display according to claim 1, wherein the progressive lighting up of the second annular luminous indicator is carried out in a dynamic fashion.

### Claim 4 (depends on 1)

Charge visual display according to claim 1 wherein the first annular luminous indicator and the second annular luminous indicator have a thin generally quadrangular-shaped profile.

### Claim 5 (depends on 1)

Hybrid or electric motor vehicle (M) comprising a charge visual display according to claim 1 fixed to the lower central area of the rear window thereof.
