SI23088A - Device and method for charging batteries by means of solar cells - Google Patents

Abstract

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.

Description

The field of technology

Photovoltaics; solar cells; recharging batteries; mobile battery charger; receiving antenna for mobile phones; supplying smaller DC power supplies.

View the problem

In areas away from populated areas, there is often a problem due to the discharging of small batteries. Such remote areas are often not connected to the electricity system.

In areas where no power system or power generation is available, however, in the event of batteries being discharged, discharged small users cease to operate (mobile phones, lamps, GPS devices, VHF stations, woodpeckers (snowfall victims ... ).

Reception problems for mobile telephony and VHF stations also occur in remote areas, especially in hilly areas where many times the signal is further disturbed.

The present invention solves the following problems:

recharging small batteries in remote areas and - providing better reception for mobile phones and VHF stations

The state of the art

Charging smaller batteries in remote areas.

Charging batteries with energy from own production based on photovoltaics, windmills, fossil fuel units ..... In the case of providing their own energy, the batteries of small users are charged with compact chargers from their own produced energy.

Charge the batteries with larger capacity batteries and suitable compact chargers

Replacement of batteries for spare batteries, if available.

Providing better signal for mobile phones and VHF stations.

The practical solutions to this problem are:

placement of a stronger receiver (which must have its own power supply) and

- placing the receiver in a better reception location (eg on the roof of a mountain bivouac ···)

Description of the new solution

The subject of the invention is a device and a method for recharging solar cells and solving technical problems: charging small consumers' batteries in remote areas and providing better reception signal for mobile phones and VHF stations.

The object of the invention can be assembled from commercially available components, which, due to the intended production in smaller batches, is very inexpensive and simplifies production.

The device according to the invention can, depending on the needs, be composed of individual components, which are selected depending on the whole device.

The device according to the invention consists of:

- solar cells interconnected in series and connected in their entirety, designed to receive solar energy and convert solar energy to direct electricity

- a plug that can be attached to chargers for charging smaller users (direct charging of small consumer batteries from a solar cell unit) or a larger rechargeable battery (energy storage)

- a mobile charger incorporating a DC / DC converter (DC converter) to provide adequate charging current

- rechargeable battery

- Battery charge controller

- connecting cables

- GSM antenna antenna and antenna cable

- antenna for VHF reception and antenna cable

The choice of individual components is mainly influenced by the frequency of use of the device and the intended position of the installation of the device. The device is designed in such a way that the unit with solar panels is foldable to facilitate transportation of the device, which is not a necessary condition for the operation of the device. There are flexible materials, such as leather or textiles, between individual solar cell assemblies so that the solar cell unit can be moved to two, four or more parts.

The device may be compactly designed so that all components are physically connected into one unit or cabinet so that the solar panels are on top, the antennas for receiving VHF and GSM signals on the side of the unit and the other components in the unit itself.

Above all, it makes sense to set separately:

- solar panels and position them in the best possible position relative to the sun,

- VHF antenna in such a way as to maximize VHF signal reception,

- GSM antenna in such a way as to maximize the reception of the GSM signal, but in such a way that the connecting cables are not too long due to the high losses mainly due to the transmission of direct current.

Due to its small size, the whole system operates at a system voltage of 12 V or 6 V, with solar cells providing slightly higher voltages (14 V or 7 V), providing a rechargeable battery.

It is possible to connect directly to a plug on a solar cell unit a small battery charger that integrates a suitable DC converter to provide adequate charging voltage.

In most cases, the device of the invention will be used to connect a battery to the receiver with solar cells via a plug to serve as a storage battery. Due to the uneven performance of the device due to weather dependence (exposure to solar energy), a battery charge controller is installed between the plug on the solar receiver and the battery pack, which allows the battery to be charged only if the solar receiver has sufficient energy production.

Antennas for receiving VHF and GSM signals are also connected to the entire device. The antennas themselves are not required to provide charging to smaller consumers, but they are integrated into the device to make mobile phones and VHF stations more charging on the system being the subject of the invention.

The simplest way is to charge consumers indirectly via a rechargeable battery, using a suitable charger with a built-in DC / DC converter (such as a car charger) to charge the batteries.

The system also allows the connection of a suitable smaller, DC-powered light bulb.

The essence of the invention is explained in more detail below with a description of an embodiment and the accompanying drawings, the drawings being part of the present patent application and the drawings show:
