Description
- i -1 CONTAINER FOR RAPID CHARGED STORAGE BATTERIES.
2 The invention concerns a container for storage batteries 3 specially suitable for short charge time batteries. The 4 application for a Swedish patent No. 7701184-9 on behalf of the YUASA BATTERY Co Ltd. shows a special device for produ-6 cing electrolyte storage batteries as far as the rapid 7 charge of said batteries is concerned. This device is 8 characterized in that it includes a plug liable to be 9 connected to the mouth of a cover in order to charge the electrolyte, where the plug comprises an input pipe and an 11 output pipe through which the electrolyte, which prepares 12 the charge for each cell of the battery, respectively flows 13 in and out. The input pipe is longer than the output pipe 14 and the output pipe is so high as to work as liquid level in the cell. The input and output pipes are generally 16 coaxial, one inside the other. This special plug is safely 17 screwed on or fastened to the mouth of each cell where the 18 electrolyte is introduced, and the circulation of the 19 electrolyte occurs in two times, one with low density electrolyte and the other with high density electrolyte.
21 During the circulation of the electrolyte, said electrolyte 22 cools down outside the battery, so that the heat removal 23 during the battery charging process shortens the time 24 necessary for charging the battery. The circulation and the cooling of the electrolyte meaningfully reduce the time for 26 charging the battery. According to a preceding and less 27 complex technique, the charge of the battery takes place by 28 introducing the electrolyte statically and without circula-29 tion. In this case the charge of the battery occurs in a few days instead of a few hours, as with the method just 31 recalled.
32 The charging process with forced circulation of the elec-33 trolyte is, however, not free from drawbacks.
34 One of the main drawbacks of the charge device just recal-led lies in the fact that the input and output pipes of the AwiL~~tJED SHEET
F
electrolyte, belonging to the plug, can get closed because of the dirt deposit connected to the circulation of the electrolyte. Therefore, the drawback is that, making use of the same devices over and over again, the circulation of the electrolyte slows down or stops. Besides, the frequent replacement of the plugs involves waste of time and expenses to bear.
The aim of the invention is to get over the drawbacks above highlighted.
The main goal of the invention is to carry out a container shaped in such a way as to fit for the quick circulation of the first-charge electrolyte, so that said circulation can take place as quickly and profitably as possible.
Moreover, the invention is meant to avoid clogs due to repeated utilization of the same devices for charges in different cells.
Another aim to achieve is that the container fitted for the circulation of the electrolyte accomplishes said circulation with the greatest effectiveness.
A final aim is that the container of the invention is cheap and, on the whole, profitable compared to the methods used up to now.
In accordance with an embodiment of the present invention there is provided a container for facilitating rapid charge of electrolyte in a storage battery comprising: a box having an open top formed with a perimetrical edge and with one or more cells, each cell of which is suitable to receive the electrolyte; a cover secured to the top for closing the box along the perimetrical edge: the cover formed with a first and a second opening for each cell: each cell of the container having at least one electrolyte feed pipe having an upper end communicating with the first opening in the cover, a lower end extending into the container adjacent to the bottom of the box, and a level pipe for establishing an electrolyte level in each cell having an upper end communicating with the second opening in the cover and a lower end extending into the container below the perimetrical edge of the top for establishing an electrolyte level in the container above the lower end of the feed pipe and the level pipe including a pipe portion formed in the cover molding.
In accordance with another embodiment of the present invention there is provided a storage battery container adapted to be rapidly charged with an electrolyte and for receiving storage battery components therein for immersion in the electrolyte comprising: a box having a bottom wall, side walls, and an open top with a peripheral edge, the box being formed with at least one cell for receiving battery components and electrolyte therein; a cover for engaging the open top of the box closing the same about the peripheral edge, the top having at least first and second openings therein: the at least one cell including at least one electrolyte feed pipe having an upper end communicating with the first opening in the cover and having a lower end portion extending into the cell and adjacent the bottom of the box, and at least one level pipe for establishing a level for electrolyte in the cell, the level pipe having an upper end communicating with the second opening in the top and lower end extending into the cell at a level above the lower end of the feed pipe for defining the electrolyte level at the lower end of the level pipe, the feed pipe being formed with a first section molded in the cover and a second interconnecting section molded in the box and the level pipe comprises a section molded into the cover, the level pipe and the feed pipe being spaced apart in the cover along a diagonal thereof for maximizing the distance therebetween.
To advantage, according to a favourite application of the invention, the electrolyte feed pipe and the level pipe are diametrically opposite to each other, so as to accomplish a turbulent circulation of said electrolyte inside the cell and in this way, therefore, the electrolyte effectively covers all the plates which have to soak in said electrolyte.
Furthermore, the possibility of making up more feed and - 3a -outlet channels of the electrolyte allows to increase the flow rate of said electrolyte and consequently to reduce the charging time.
One of the advantages in reducing the charging time lies in the fact that batteries without charge, which are therefore completely inert, can be produced and stored, and consequently the battery cannot deteriorate because of long storage.
Besides, it can be expected that the battery production cycle undergoes a change lying in the fact that the first charge of the battery, since it is short, can also be directly assigned to the distributors of said batteries, who provide for the charge on customers' request shortly before delivery.
Moreover if said at least one electrolyte feed pipe is obtained during the molding phase of the box, it forms a single body with the same box. Therefore the electrolyte feed pipe doesn't reduce the inner space utilized by the standard plates inserted into the container.
Further distinctive features and peculiarities of the invention will be better highlighted in the description of a favourite application of the invention illustrated in the attached table as possible directions, without, however, setting limits:

1 - figure 1 shows a container of the invention for single-2 celled batteries with separate box and cover;
3 - figure 2 shows the container of figure 1 with joined box 4 and cover;
- figure 3 shows a cover of the container of the invention 6 for more-celled batteries;
7 - figure 4 shows a box compatible with the cover of figure 8 3;
9 - figures 5 and 6 respectively show a variant of a cover and of a box that can be connected to each other according 11 to the invention.
12 With reference to the above-mentioned figures, it can be 13 noticed that the battery, referred to as a whole by 1, is a 14 single-celled battery and has a cover 2 and a box 3. On the cover 2, as can be observed in figure 2, as well as holes 4 16 and 8 suitable to receive the positive and negative poles, 17 there is also a pipe 5 that is the level pipe noticeable in 18 figure 1 too. In the executive variant of the example, this 19 pipe 5 is directly obtained upon molding of cover 2.
Diametrically opposite to pipe 5 there is another pipe 6, 21 also made on the cover by molding, which, as it will be 22 explained, will later be fitted into pipe 7 belonging to 23 box 3. Said pipe 7 is the electrolyte feed pipe and, in the 24 case of the example, is directly molded along with box 3 and extends for the whole height of the box to stop shortly 26 before the bottom. When cover 2 is sealed on box 1, after 27 fitting the battery elements 10 into it, the small pipe 6 28 is inserted inside the feed pipe 7, so as to make up a 29 single feed channel. When the electrolyte is introduced in battery 1 for the first charge through pipes 6 and 7, which 31 are now joined, it directly reaches the bottom of box 3 and 32 covers the elements 10 until it fills the battery cell up 33 to the level predetermined by the height of pipe 5; when 34 the electrolyte reaches said level, it flows out of said pipe, leaving unchanged the inner level. As a consequence a An'~;~~CD Si-BEET
~I~~i~~i~
- S -1 circulation occurs between the feed pipe 6 and the outlet 2 and level pipe 5.
3 The reciprocal position between the feed pipe 6 and 7 and 4 the outlet pipe 5 avoids creating areas on the metallic elements which are not lapped by the electrolyte. Besides 6 the possibility of carrying out feed and outlet pipes of a 7 meaningful section or a multiplicity of said pipes, either 8 feed or outlet pipes, also allows to ensure a rather impor-9 tant electrolyte rate flow, so as to create optimum condi-tions for reducing the charging time. As a matter of fact 11 the circulation speed of the electrolyte quickens the 12 battery charging process, as, on the other hand, the char-13 grog process is quickened by the fact that the electrolytic 14 bath affects all the plates rather intensely.
In the case of figures 3 and 4, we can observe respectively 16 the cover and the box of a car starter battery which con-17 sists of more cells, here referred to by numbers 11, 12 and 18 13. It can be noticed that in this case each cell is re-19 spectively provided with an electrolyte feed pipe and 'a level pipe. More precisely cell 11 is provided with feed 21 pipe 14 and level pipe 15; cell 12 is provided with feed 22 pipe 16 and level pipe 17; cell 13 is provided with feed 23 pipe 18 and level pipe 19. All the feed pipes 14, 16 and 18 24 belong to box 20, while the level pipes 15, 17 and 19 belong to cover 30, which is then sealed on box 20. In this 26 case too, in correspondence with each feed pipe on the 27 cover there will be a small pipe 141, 161 and 181 which 28 will allow the junction of the lower feed pipe belonging to 29 the box up to the outlet on the cover surface.
It is clear that in such a container as that represented by 31 the invention it is possible to make the electrolyte flow 32 with simple circulation means, such as pipes through which 33 the electrolyte is moved by a certain head provided, for 34 example, through a pump.
Another executive variant of the invention is shown in A.f,~~c't;nrn r~ :~rT

1 figures 5 and 6, where it can be noticed that cover 50, 2 besides the holes of poles 51 and 52, has two small pipes 3 53 and 54 molded along with the cover and said two small 4 pipes have the same diameter and the same thickness as the feed pipe 61 and level pipe 62 obtained upon the molding of 6 box 60.
7 In this way, when the cover 50 is sealed on box 60 along 8 the perimetrical edge, also the small pipe 53 is sealed on 9 the feed pipe 61 and likewise the small pipe 54 is sealed on the level pipe 62.
11 The examples of figures 1, 2 and 3 show that the electro-12 lyte feed pipe has been molded on the box.
13 This permits that the feed pipe inside the container 14 doesn't reduce the inner space utilized by the standard plates inserted into the same container.
16 There is no difference if the electrolyte is molded separa-17 tely and is then introduced into the box and fixed on a 18 corresponding hole on the cover.
19 Another solution could be to directly mold the feed pipe along with the cover and then to introduce said pipe into 21 the electrolyte.
