Abstract

A battery charger includes a solar panel that may be integral to a mobile telephone. In low light conditions a diode prevents the battery discharging via the solar panel.

Description

1 2418081
Description
Solar powered mobile telephone battery charger Mobile telephones are widely in use around the world, communicating via cellular, satellite or home base station to land line. All of these telephones have a battery to power them, however, as they are not connected to a power source, the batteries run down until the user can get to a power source to recharge them.
The invention uses a solar photovoltaic panel, which converts light to electricity and charges the battery (or reduces battery drain) of a mobile telephone. The panel is integral to the mobile telephone.
There are battery chargers for mobile telephones already on the market including solar powered and hand driven generators, but these are separate units and not integral to the telephone. Users have to carry these chargers as well as the telephone.
The invention allows the user to charge the mobile telephone battery, or to increase the time until battery discharge before access to charging from other means can be done.
Looking at the accompanied drawing; Figure 1 shows the front of a typical mobile telephone, with a screen to view numbers entered or for additional features, a keypad and, in this example, a small protruding aerial.
Figure 2 shows the rear of the mobile telephone and an example of where the solar panel could be placed.
Figure 3 shows the rear of the mobile telephone with the solar panel attached to the removable battery cover.
The power is fed to the battery via wires coming from the photovoltaic panel. A blocking diode in the wiring stops the battery from discharging through the panel when insufficient light falls on the panel.
Any part of the mobile telephone's body can be used for the solar panel attachment. The whole of the telephone's body could be used, although it is envisaged that the unused areas of the telephone body will be utilised.

Claims (5)

  1. Claims 1. A solar powered mobile telephone battery charger using a
    photovoltaic panel.
  2. 2. The panel as in claim 1 which is integral with the mobile telephone.
  3. 3. The photovoltaic panel as in claim 1 has a blocking diode, which stops battery discharge when insufficient light powers the photovoltaic panel.
  4. 4. The panel as in claim 1 and 2 is built into the mobile telephone at manufacture or as a post manufacture conversion.
  5. 5. The solar panel can be made from any material, which can produce sufficient power from light.
