Description

Self-maintenance Battery Cover System
DESCRIPTION Technical Field
The invention relates to cover systems used in the battery.
The invention especially relates to cover systems which are used in the battery, provide reinforcement with distilled water or acid solution between the cover voids in case acid solution level in the battery falls below the minimum level and keep said level at desired values and thereby pave the way for presenting a self-maintenance battery.
State of the Art
Today, different types of batteries are used as electric energy source in vehicles. The most common types out of these are maintenance batteries and maintenance-free batteries.
In general, various numbers of cells, acid solution provided in the cells and plate groups immersed therein are disposed in the batteries. A primary cover, on the other hand, attached in a sealed manner is disposed thereon. Basicaliy, said structure is available both in maintenance batteries and maintenance-free batteries. Distinctly, in maintenance batteries, one plug is provided for each battery cell on the primary cover and is clamped by means of a screwdriver and connected. In maintenance-free batteries, however, a secondary cover attached in a sealed manner on the primary cover is disposed. A grooved void is formed which is disposed between the two covers and consists of grooves, and will allow the return of water vapor by condensation into the battery cells again during when gas and water vapor formed therein during the operation of the battery are discharged.
In batteries, when acid solution level falls below the minimum level in the battery, the battery starts to fall. In this case, in the maintenance batteries, the user opens the plugs provided one for each cell on the battery cover by means of a screwdriver and adds distilled water therein to a suitable level. However, in order for the user to realize said fall, s/he should control the battery at certain intervals or the battery is supposed to fail. Furthermore, the distilled water added into the battery cells by the user after the failure can decrease the density of the acid solution in the battery cells and the performance of the battery.
In the maintenance-free battery, however, the user does not add distilled water into the battery cells. It is ensured that the water vapor, which passes through the grooved void between the primary cover and the secondary cover, returns into the battery cells again by condensation during when the gas formed during the operation of the battery is discharged. In this manner, the water loss in the maintenance-free battery is tried to be minimized. However, the water vapor exiting the cells cannot return to the same cell again after being condensed. This is because the condensation occurs within the grooved void formed between the secondary cover and the maintenance-free battery primary cover and said void is open to all the battery cells. Moreover, as the condensed water vapor returns to the battery cells as distilled water, the density of the acid solution in the maintenance-free battery decreases in time. This situation decreases the battery performance and can stop the functioning of the battery in time. Besides, the water vapor exiting the cells is not fully condensed. Some of the water vapor is discharged to the atmosphere from the gas discharge portion of the battery. In said situation, acid solution levels in the maintenance-free batteries decrease in time.
The primary cover and the secondary cover in maintenance-free batteries are produced with plastic injection method. The multi-groove structure disposed on the primary cover and the secondary cover and allowing condensation complicates the plastic injection process and creates quality problems. Moreover, it has a need for long cooling periods. Said situation increases the production cost of the primary cover and secondary cover of the battery. Furthermore, due to the same reasons a difficult and expensive production of mold is performed in the plastic injection molds used.
Having the application No. 2009 01451 and the title "Fully maintenance-free, sealed plastic battery cover with two components or O-ring", the patent relates to a maintenance-free battery similar to the one described above. Said invention is a sealed plastic battery cover used in the battery comprising a secondary cover on the body cover, characterized in comprising at least one fitting lug positioned on said secondary cover in order to allow said secondary cover to be fixed on said body cover without welding and/or heat sealing; at least one lug bearing positioned on said body cover accommodating said fitting lug; and at least one sealing element positioned between said secondary cover and said body cover in order to allow inner and/or outer sealing of said secondary cover and said body cover.
To conclude, a development is deemed necessary in the related technical field due to the need for cover systems which are used in the battery, provide reinforcement with distilled water or acid solution between the cover voids in case acid solution level in the battery cells falls below the minimum level and keep said level at desired values and thereby pave the way for presenting a self-maintenance battery, and the inadequacy of the existing solutions. Object of the Invention
The present invention relates to a self-maintenance battery cover system meeting the aforementioned requirements, eliminating all the disadvantages and offering some advantages. The main object of the self-maintenance battery cover system according to the invention is to comprise switches which allow automatic supply of acid solution or distilled water in the void into the battery cells in case acid solution level in the battery cells and the void having reinforced acid solution or distilled water between the primary cover and secondary cover falls below a certain level. In this way, it is ensured that the acid solution level continuously automatically remains above the minimum level in the battery cell. Thus, the user errors are avoided thanks to carrying out maintenance of the battery without the need for any intervention by the user. Accordingly, physical life of the battery is also increased.
Another object of the invention is to allow the density of the acid solution in the battery cells to remain at desired intervals in case of reinforcing the battery cells by adding acid solution or distilled water to the void between the primary cover and secondary cover. Therefore, while the physical life of the battery is increased, the operating performance thereof is also maintained high levels,
Another object of the invention is to present a simpler structure when compared to the other cover systems of the prior art as a grooved structure allowing the condensation of vapor is not disposed thereon. In this manner, not only the production processes are facilitated and shortened but the production costs are reduced, as well. Accordingly, the costs of the mold are also reduced.
In order to achieve the aforementioned objects in the most general terms, acid solution or distilled water is provided in the void between the primary cover and secondary cover. At least one reinforcement hole which provides the connection between battery cells and void and allows the passage of fluid is formed on said primary cover. At least one switch which moves up-down according to the acid solution level in the battery cells and thereby opens/closes the reinforcement holes is positioned to said reinforcement holes.
The structural and characteristic features and all the advantages of the present invention will be more clearly understood thanks to the figures below and the detailed description written with reference to those figures and therefore, the evaluation needs to be done by taking said figures and the detailed description into consideration.

Void connection hole (1.2.3) allowing the filling of acid solution or distilled water (1.12) into the void (1.6) is formed on the secondary cover (1.2). Said void connection hole (1.2.3) is closed by means of a plug (1.4) illustrated in Figure 7.
The perspective and disassembled views of the switch (1.3) disposed in the self-maintenance battery cover system (10) according to the invention are shown in Figures 6a and 6b, respectively. The switch (1.3) consists of a switch lower part (1.3.1) capable of being positioned above the acid solution (1.7) with its low density; a switch upper part (1.3.2) allowing the positioning of the switch (1.3) by fitting into the switch holder (1.1.2); a holding lug (1.3.2.1) which prevents the switch from falling down in the x direction by attaching to the switch holder (1.1.2); and a sealing element (1.3.3) surrounding the switch upper part (1.3.2) and preventing the flow of acid solution or distilled water (1.12) through the reinforcement hole (1.1.3) when closed. The inner portion of the switch lower part (1.3.1) is designed to be empty with the aim of maintaining the density of the switch (1.3) at a low level. Holding lugs (1.3.2.1) are formed at the ends of the switch upper parts (1.3.2). The holding lugs (1.3.2.1) are formed in a manner to pass through the switch holders (1.1.2) and to be attached thereto and in this manner, the switch (1.3) is prevented from falling down in the x direction from above the primary cover (1.1) by attaching to the switch holder (1.1.2) on the primary cover (1.1). Sealing element (1.3.3) has a structure to be fitted into the sealing element bearing (1.1.5) and to provide sealing with effect of the buoyant force applied to the switch (1.3).
The upper view showing cross-sectional directions of the battery (1) with the self-maintenance battery cover system ( 0) according to the invention being disposed therein, is given in Figure 8. In Figures 9 and 10, on the other hand, said cross-sectional views are given. Maximum acid solution level (1.9) and minimum acid solution level (1.10) at which the battery (1) can operate, are shown thereon. First, plate groups (1.8) are placed in the battery cells (1.5.1) and spot-welded to each other during the first assembly of the battery (1). Then, the primary cover (1.1) on which the switches are placed (1.3) is adhered on the battery box (1.5). The battery ceils (1.5.1) are filled with acid solution (1.7) through the filling holes (1.1.1) thereafter. Subsequent to this process, battery (1) is controlled and charged. Then, the secondary cover (1.2) is positioned on its place on the primary cover (1.1) and adhered thereto. Meanwhile, closure slots (1.2.4) correspond to the filling holes (1.1.1) on the primary cover (1.1) and allow the closure thereof. The void (1.6) formed between the primary cover (1.1) and secondary cover (1.2) as a result of the adherence thereof is filled with acid solution or distilled water (1.12) through the void connection hole (1.2.3). Finally, void connection hole (1.2.3) is closed with the plug (1.4) and the connection thereof with the outside is cut. In this manner, the assembly of the battery (1) is completed. The density of the switch (1.3) is lower than that of the acid solution (1.7) in the battery cells (1.5.1). For this reason, while the level of acid solution (1.7) in the battery cells (1.5.1) is above the minimum acid solution level (1.10), the switch is subjected to the buoyant force applied by the acid solution (1.7). The sealing element (1.3.3) is fitted into the sealing element bearing (1.1.5) with the effect of this buoyant force in the y direction, in this manner, acid solution or distilled water (1.12) in the void (1.6) disposed between the primary cover (1.1) and secondary cover (1.2) Is prevented from flowing through the reinforcement hole (1.1.3) and entering the battery cells (1.5.1). For this reason, while the level of acid solution (1.10) in the battery cells (1.5.1) falls below the minimum acid solution level (1.7), the buoyant force applied to the switch (1.3) by the acid solution (1.7) is removed and the switch (1.3) moves in the x direction with the effect of its weight. In this manner, seating element (1.3.3) leaves the sealing element bearing (1.1.5) and sealing is eliminated in this area. As a consequence, the front of the reinforcement hole (1.1.3) is opened and acid solution or distilled water (1.12) in the void (1.6) enters into the battery cells (1.5.1) by flowing through the reinforcement hole (1.1.3). Thusly, the level of acid solution (1.7) in the battery cell (1.5.1) is continuously maintained above the minimum acid solution level (1.10). In this manner, the battery (1) with self-maintenance battery cover system (10) maintains the amount of acid solution (1.7) in the battery cells (1.5.1) between the determined maximum acid solution level (1.9) and minimum acid solution tevei (1.10) during the physical life of the battery (1) without any intervention to be made by the user or any external equipment. Furthermore, the density of the acid solution (1.7) in the battery cells (1.5.1) is enabled to remain at desired intervals in case of placing acid solution or distilled water (1.12) in the void (1.6) between the primary cover (1.1) and secondary cover (1.2) and reinforcing the battery cells (1.5.1).
The gas and the water vapor produced as a result of the chemical reactions and the heat, respectively in the battery cell (1.5.1) move toward the filling holes (1.1.1) and then to the gas and vapor discharge channel (12.2) on the secondary cover (1.2) during the operation duration of the battery (1). The gas and vapor accumulated therein are discharged through the gas and vapor discharge hole (1.2.1) disposed at the ends of the gas and vapor discharge channel (1.2.2) and opening to the outside of the secondary cover (1.2). In a preferred embodiment of the invention, the adherence process between the battery box (1.5) and primary cover (1.1) and the primary cover (1.1) and secondary cover (1.2) is performed by means of the hot plate method.
