<p>The subject of the invention is a device and a method for charging batteries by means of solar cells, which is solving two technical problems: how to charge batteries of small current-consuming devices on remote areas and how to assure a better receiver signal for mobile phones and VHF stations. The whole device can be structurally implemented as a compact one in a single housing or the solar cell unit and both antennas can be set into a position with a better reception of solar energy or a VHF and/or GSM signal. The energy obtained from the solar cell unit serves to charge the accumulator battery via a male connector on the solar cell unit and via a controller for charging accumulator batteries. On the controller for charging accumulator batteries, a heat drainer is mounted for dissipation of energy into the environment, in case the energy is not drained off into the accumulator battery. The antennas for the reception of GSM and VHF signals are also mounted on the device. At the side of the device, a charger is mounted for smaller current-consuming devices, containing a built-in DC/DC converter which takes care of appropriate charging voltage for small consumer batteries. There is also a plug for connection of a consumer, such as a direct current bulb, at the side of the device.</p> |
