    Battery level control system. Compared with other systems or devices that allow detecting the level of electrolysis in batteries, the system of the invention not only warns of such a fact, but prevents the battery or batteries from being damaged by acting directly on the control electronics of the vehicle or machine itself in which the battery is installed, thus ensuring that it is not damaged. For this, the system is composed of a probe (1) of the level of electrolysis in a battery (2), an electronic control module (3) associated with said probe (1) as well as the electronic control of the machine or vehicle in question, with the particularity that the electronic control module (3) is equipped with programming firmware to interpret the signals received from the probe (1), and limit the electrical performance of the vehicle or machine to the that the battery is associated according to the level of electrolysis thereof detected by the probe (1) and through control signals sent to the control electronics of the machine or vehicle in question.

    5 OBJECT OF THE INVENTION
    The present invention relates to a system that has been specially designed to control the level of electrolysis of electric batteries.
    The object of the invention is therefore to be able to control the level of battery electrolysis in certain types of vehicles or machines, in order to avoid or prevent breakdowns caused by a low level of the electrolyte.
    For this, the system of the invention not only detects said low level, but also acts on the control electronics of the vehicle or machine in question, reducing its electrical performance, in order to demonstrate said need for maintenance of the battery or batteries, without the user of the vehicle or machine being able to ignore such maintenance work.
    The system of the invention has been specially conceived for its implantation in the batteries of forklift trucks and the like, although it is equally applicable to other vehicles or machines that require similar performance.
    25 BACKGROUND OF THE INVENTION
    In the practical scope of the invention, that of the batteries, the major cause of their deterioration and loss of autonomy for them is determined by the low
    30 levels of electrolyte in the battery cells.


    Thus, it is important to control the level of the electrolyte in the cells, an operation that to date has been done by visual inspection, so that, when there is not enough time, it is a task that is usually postponed, which can take that when said low electrolyte level is detected it is too late and the battery is already damaged.
    Trying to obviate this problem, there are known devices that are installed in the battery itself, consisting of level sensors associated with a small control circuit, which through a LED, indicate the level of electrolyte in the battery when it goes To be charged.
    However, this device is independent of the electronics of the vehicle or machine to which the device is associated, which in practice means that, even if a low level of electrolyte is detected, the vehicle or machine can still be used, with the consequent risk of damage to the battery. DESCRIPTION OF THE INVENTION
    The battery level control system that is recommended resolves in a fully satisfactory way the problem previously exposed in each and every one of the aspects mentioned as it is a fully automated system, which allows to quickly and efficiently notice the drop in the levels of electrolyte in the battery cells well in advance so that said battery or batteries are not damaged in its operation, interacting the system with the vehicle or machine in question, in order to prevent damage to the battery, reducing or even canceling the electrical performance of the machine, if necessary, which necessarily obliges the user of said machine or vehicle to perform the proper maintenance operations for the battery.
    For this, and more specifically, the system of the invention is constituted from at least one electrolysis level probe that will be installed in the corresponding battery to be controlled, and an electronic control module, which will be connected to said probe as well as to the
    control unit, drive or control circuit of the machine or vehicle in question.


    From this structuring, the electronic control module will receive the electrolysis level readings of the battery collected by the probe, so that, when an electrolysis level is detected below a required minimum, the control module sends a signal to the control electronics of the machine or vehicle in question, to reduce its performance, which automatically demonstrates the need to have to check the condition and maintenance of the battery or batteries of the machine or vehicle in question.
    In accordance with another feature of the invention, it is provided that the electronic control module has two micro-sensors to adapt the speed limitation signal to the electronics of the machine based on two types of signals, NAMUR type signals , or negative signals.
    In parallel, the module has an additional output for an auxiliary treatment (horn, headlamp, etc.), which allows switching a high signal (NC) and a low signal (oV)
    In this way it is possible to ensure that the batteries of the vehicle or machine in question are not damaged, without drastic cuts in operation, unless they are strictly necessary, so that as a general rule a reduction in performance will be obtained that allows the user of the machine or vehicle to finish at a slower pace the work that was being done to then proceed to perform the necessary maintenance maneuvers for the battery of said vehicle or machine, thus preventing damage to said battery. DESCRIPTION OF THE DRAWINGS
    To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, an accompanying plan is attached as an integral part of said description. For illustrative purposes and not limitation, the following has been represented:


    Figure 1 shows a schematic diagram of the electronics that participates in a battery level control system made in accordance with the object of the present invention. PREFERRED EMBODIMENT OF THE INVENTION
    In view of the above-mentioned figure, it can be seen how two fundamental elements are involved in the battery level control system that is recommended, a probe (1) of the electrolysis level in a battery (2), and an electronic control module (3) associated with said probe (1) as well as a control unit, variator or control electronics (4) of the machine or vehicle in question.
    The probe (1) will incorporate a sensor (5) of the electrolysis level in the battery, which will be installed so that it is 3 mm from the separators of the different cells of said battery, connecting through a pair of connectors (6 ) and (7) to the battery terminals (2).
    The probe readings (1) are sent to the electronic control module (3) through a cable (8) with its corresponding connector (9), complementary to a connector (10) associated with the electronic control module (3) , which facilitates the installation of the system.
    Said control module (3) will be provided with an electronics to interpret the signals received from the probe (1), feeding the same directly from the battery (2) by means of respective connection cables (1213).
    The control module (3) has an output cable (14) terminated in a connector (15) complementary to a connector (16) through which it communicates directly with the control electronics (17) of the machine or vehicle from which be concerned.
    From this communication bus, the electronic control module (3) can act on said control electronics (4) of the machine or vehicle in question, reducing


    their electrical performance or canceling them depending on the degree of affectation of the battery (2).
    The electronic control module (3) may have micro-sensors (18) for
    5 adapt the output and communication signals with the control electronics of the machine or vehicle in question in order to adapt to different types of machines / vehicles and present a universal character.
    In this way, the electronic control module (3) can send NAMUR signals, that is,
    10 by resistance / voltage levels, or a negative switching signal, depending on the electronics to be controlled.
    In the specific case that the control machines are electric, thermal and similar forklifts, if they come standard with reduction inputs of
    15 speed in its control module, the appropriate inputs will be used, while in the case of machines that do not have speed reduction inputs it will be possible to install the adaptation electronics, or directly block the lifting system.
    Optionally, the electronic control module (3) has an additional output for a
    20 auxiliary treatment (horn, headlight, etc.), which allows switching a high signal (NC) and a low signal (oV).
