Definitions

• the present invention concerns in general the photovoltaic panels or modules field, and refers in particular to a system for managing the charging of a plurality of batteries with electric energy generated by one or more photovoltaic panels or modules. State of the Technique
• Photovoltaic panels have been devised for the conversion of solar light into electric energy.
• the electric energy produced in this way is then accumulated in electric batteries to be able to manage its use over a period of time.
• the present invention has been devised on the basis of this need, and in fact its object to provide a system for an innovative controlled charging system, not for one battery at a time, but several batteries together and with a shorter charging time, being able, furthermore, to use devices which are easily accessible, but combined in an original way.
• Another object of the invention is to provide a system for charging batteries using electric energy produced by at least one simply built and particularly functional and reliable photovoltaic panel. Said objects are achieved, according to the invention, in a system for charging a plurality of batteries at the same time using electric energy produced by at least one photovoltaic panel according to claim 1 in the appendix.
• Fig. 1 shows a general layout in a block diagram of the system of the invention
• Fig. 2 shows an example of a device for controlling the cyclic charging of several batteries.
• the system proposed basically comprises at least one photovoltaic panel, globally indicated by number 11 , and a logic controller 12 designed to control the charging of several electric batteries 13.
• the photovoltaic panel 11 can be any of the known types, that means including direct natural illumination or concentrated illumination by means of appropriate lenses, however able to convert the luminous radiation into electric energy.
• the electric output of the or each photovoltaic panel 11 is connected by means of connecting lines 14 to the input poles of the controller 12, to power it
• the logic controller 12 is preferably the static systems type 15 including a series of relays managed by PLC 16 depending on the number of batteries 13 to be charged.
• Each of these static systems 15 is connected at output, by means of lines 17, to the positive and negative poles of a respective battery 13.
• the batteries 13 are standard and the charge of each of them can be controlled by a charge regulator 18.
• the charge regulators, where present, can be integrated with the controller 12. Therefore, as a whole the photovoltaic panel produces the electric energy that feeds the logic controller and, by this means, it is delivered to the batteries to be charged with or without the interposition of charge regulators.
• the controller is configured for cyclic activation of the static systems in order to emit very brief impulses of current towards the batteries so as to charge them individually and at the same time in rotation.
• the batteries are not fully charged one after the other, but cyclically and progressively all at the same time by means of impulses of current generated by the controller.
• the system described above can however be modified or have additional components without by this moving outside the objectives of the invention.
• electromechanical, mechanical or pneumatic devices to generate impulse electric current to the batteries to be charged can be used in an equivalent way.
• Fig. 2 represents an example of an electromechanical device 18 according to which the electric output of a photovoltaic panel is connected, for example from the negative side (-), directly to the batteries 13 to be charged whereas the positive side (+) is connected to a current distributor which comprises the same number of stationary contacts 19 as there are batteries to be charged 13 and a rotating brush 20 driven by a relative motor - not shown-: in this case the turning brush interacts cyclically with each of the stationary contacts to generate in fact the impulses of current to progressively and contemporarily charge all the batteries.
