Description
~1~7817 BACKGROUND AND OBJECTS OF THE INVENTION
The present invention concerns an electrical accumulator cell intended for connection with a liquid filling or charging system common to several cells. The system is intended for the replenishment of the electrolyte with water and also serves as a ventilation system for gas formed in the cell.
The invention is intended primarily to be applied to lead accumulator cells and will be described below in connec-tion therewith. The invention is applicable, however, to all types of accumulator cells in which electrolyte is used.
The use of electrolyte in accumulator cells varies to a high degree with the application range of the cells. Batteries which are subjected to constant charges and discharges, as, - for example, in electric-powered trucks, consume large amounts ,s of electrolyte. The same is true of batteries which are exposed to strong and long-lasting over-charging. In such cases the control and filling-up of electrolyte may be required as often as once every twenty-four hours. In other cases, where the operating conditions are not hard on the battery, it may be sufficient to control and fill-up the electrolyte a few times during the year.
- The consumption of electrolyte is also affected by such factors as the composition of the lead-base alloy in 1~7817 'he electrode grid and the age and general condition of the battery. It is not unusual for electric trucks to have batteries with up to 50 cells. In larger enterprises employing many trucks, the daily control and filling-up of electrolyte in the cells therefore represents a task of extensive proportions. During the control and filling-up process the plug or fuse screwed into the venthole may be removed, the liquid level must be controlled, and the ;~
filling-up must be carried out, whereupon the plug is replaced. In order to facilitate this task, certain batteries are provided with a plug having a level-indicating device and with an aperture for the filling-up that can be quickly opened and closed. Such measures have reduced the maintenance problems, but each cell continues to require individual checking.
The present invention concerns a cell for connection with a common liquid filling system. This means that by feeding the liquid at a single point one obtains a filling-up to the controlled level in several cells at the same time.
Normally, a single filling point should be sufficient for the entire battery.
;L~7817 A common liquid filling system and the cells connected with it must meet certain requirements. The system must be easy to mani~ulate and make possible the quick filling of all the cells. Depending on the size of the battery, a dura-tion of from S to 10 minutes can be accepted. The system must also be independent of the position of the cells, at least to a certain extent; that is, it must function even when the cells for some reason or other are on different planes or at different angles. Furthermore, it must operate '~ 10 automatically, i.e., no supervision or measure must be neces-sary while the filling takes place. The system, moreover, must ~ be safe in operation, and in case of possible disturbances, ,' overfilling must be avoided.
BRIEF SUMMARY OF THE INVENTION
These objects are achieved by apparatus for delivering liquid to the interior of an accumulator cell. The apparatus comprises a liquid inflow conduit communicating with the interior of the cell to conduct liquid thereto from an outside source. A liquid outflow conduit communicates with the interior of the cell. A float is arranged within the cell to follow a rising and dropping level,of liquid within the cell. A liquid conductor is connected to the float so as to be movable, in response to raising and lowering of the liquid level, between 7l~17 a liquid supply position and a liquid non-supply position.
In the liquid supply position, liquid from the inflow conduit combines with liquid in the cell, when liquid in the cell is below a given level. In the liquid non-supply position, liquid is conducted by the conductor from the inflow conduit to the outflow conduit, when liquid in the cell is above the given level.

Figures 1, 2 and 4 illustrate the basic concept of the invention while Figure 3 shows in greater detail a preferred form of cell for carrying out the invention.
7~3~7 DETAILED DESCRIPTION OF PREFERRED
EMBODIMENTS OF THE INVENTION
Figure 1 shows the upper part of an electrical accmulator cell according to the invention. Within the cell container 1 there are disposed electrodes 2, which are joined to pole taps or plugs 3 and 4. In the container there is also disposed electrolyte 5, the surface of which ; 16 is here shown at the highest level desired. On the ,, ~i~ electrolyte there is a float 6 which is kept in place by a lever arm 12, connected with the cell container's cover by a link 13. On the upper side of the float there is a bowl-like container 7. Conduit pipes for the inflow 10 and the outflow 11 of the liquid are attached to the upper side of the cell by means of a holder 9.
The liquid is conveyed to and away from the cell by the tubes or hoses 15 and 14. The flow direction of the ` liquid is indicated by arrows in the figure. Figure 2 shows the details essential for the filling-up function in the same cell. In Figure 2 the cell with the surface 16 of the elec-trolyte is shown at such a low level that an additional supply of liquid is desirable. By way of the tubes 14 and 15 the cell can be coupled together with other such cells, and it has proved possible to connect in series up to 10 cells, and also to con-nect pairs of lines 14, 15 in parallel to a common main line.
~7~17 If now it is assumed that the system is to be exempli-fied by the cell shown in the figure, the tube or hose 15 is joined to a water reservoir and tube 14 is joined to a suction mechanism such as a - The latter makes it possible to obtain a low pressure, so that the pressure difference between the inflow 10 and the outflow 11 is about 1 kPa. Water then flows through the tube 15 and the inflow 10 into the cell. If thé electrolyte level in the cell is too low, as is the case in Figure 2, then the liquid flows down into the bowl of the float and from the latter down into the cell. When the desired level has been reached, as is the case in Figure 1, the inlet end of the outflow tube enters the liquid,via the upwardly open end of the bowl and is able to suck liquid therefrom. Thus, liquid is collected in the bowl and sucked out again vla the outflow 11 and the tube 14. Thus, the bowl 7 serves as a conductor to transfer liquid directly from the inflow conduit to the outflow conduit, when the bowl is in the liquid non-supply position of Figure 1.
The function of the embodiments shown in Figures 3 and 4 is the same as described above. The difference lies in the control of the float, which according to Figure 3 is carried out by two pins or pegs 20, 21 which stick up in the inflow pipe and the outflow pipe.
~78~7 In Figure 4 control is carried out by a pin 25.
This pin serves as a level indicator and is therefore enclosed in a transparent covering 27. In order to prevent the float and the guiding pin from sinking too far down, the upper end of the pin has been provided with a broadening or widening part 26 which engages a stop.
The embodiment shown in Figure 3.is provided with a bow-shaped piece or ring 19 for retaining the float, which thus is guided or controlled by the pins 20 and 21. The ring 19 is fixed in a holder 23 having a circular outer cross-section, wherein the inflow and outflow channels 10 and 11 are bored or drilled and provided with connection nipples 17 and 18.
The holder is movably attached to the fastener 22 and is fixed tightly against it by means of an O-ring 24. The fastener 22 is fitted in the usual manner in the top of the container by means of a screw thread. Because the holder 23 is movable in the fastener 22, the holder can be adjusted in such a way that the suitable position is obtained for the tube or hose couplings 17 and 18.
Openings can also be made in the cover of the container for the control of the temperature and the density of the electrolyte. It is important, however, that these openings be provided with tightly fitting plugs and that also the cell ~7817 be completely tight, for example, in the seam or groove between the container and the cover. To control this, the cell is subjected to an overpressure of about 20 kPa, whereby a pressure drop of at the most 4 kPa is permitted during a period of 10 seconds.
In order to safeguard the liquid flow, the ends of -~ the inflow and outflow tubes can be cut obliquely or on the bias, as is shown in Figures 3 and 4. One can also use other arrangements to prevent the openings of the tubes from becoming wholly or partly blocked by the bottom of the bowl.
Of course, other realizations of the invention than those described are also possible. For example, the bowl in which the inflow and outflow tubes terminate may be placed elsewhere than dlrectly on the upper side of the float, and the control and placing of the float may also be different from the description given above.
Although the invention has been described in connec-tion with a preferred embodiment thereof, it will be appre-ciated by those skilled in the art that additions, modifications, substitutions and deletions not specifically describ-d may be made without departing from the spirit and scope of the inven-tion as defined in the appended claims.

7~3~7 DETAILED DESCRIPTION OF PREFERRED
EMBODIMENTS OF THE INVENTION
Figure 1 shows the upper part of an electrical accmulator cell according to the invention. Within the cell container 1 there are disposed electrodes 2, which are joined to pole taps or plugs 3 and 4. In the container there is also disposed electrolyte 5, the surface of which ; 16 is here shown at the highest level desired. On the ,, ~i~ electrolyte there is a float 6 which is kept in place by a lever arm 12, connected with the cell container's cover by a link 13. On the upper side of the float there is a bowl-like container 7. Conduit pipes for the inflow 10 and the outflow 11 of the liquid are attached to the upper side of the cell by means of a holder 9.
The liquid is conveyed to and away from the cell by the tubes or hoses 15 and 14. The flow direction of the ` liquid is indicated by arrows in the figure. Figure 2 shows the details essential for the filling-up function in the same cell. In Figure 2 the cell with the surface 16 of the elec-trolyte is shown at such a low level that an additional supply of liquid is desirable. By way of the tubes 14 and 15 the cell can be coupled together with other such cells, and it has proved possible to connect in series up to 10 cells, and also to con-nect pairs of lines 14, 15 in parallel to a common main line.
~7~17 If now it is assumed that the system is to be exempli-fied by the cell shown in the figure, the tube or hose 15 is joined to a water reservoir and tube 14 is joined to a suction mechanism such as a - The latter makes it possible to obtain a low pressure, so that the pressure difference between the inflow 10 and the outflow 11 is about 1 kPa. Water then flows through the tube 15 and the inflow 10 into the cell. If thé electrolyte level in the cell is too low, as is the case in Figure 2, then the liquid flows down into the bowl of the float and from the latter down into the cell. When the desired level has been reached, as is the case in Figure 1, the inlet end of the outflow tube enters the liquid,via the upwardly open end of the bowl and is able to suck liquid therefrom. Thus, liquid is collected in the bowl and sucked out again vla the outflow 11 and the tube 14. Thus, the bowl 7 serves as a conductor to transfer liquid directly from the inflow conduit to the outflow conduit, when the bowl is in the liquid non-supply position of Figure 1.
The function of the embodiments shown in Figures 3 and 4 is the same as described above. The difference lies in the control of the float, which according to Figure 3 is carried out by two pins or pegs 20, 21 which stick up in the inflow pipe and the outflow pipe.
~78~7 In Figure 4 control is carried out by a pin 25.
This pin serves as a level indicator and is therefore enclosed in a transparent covering 27. In order to prevent the float and the guiding pin from sinking too far down, the upper end of the pin has been provided with a broadening or widening part 26 which engages a stop.
The embodiment shown in Figure 3.is provided with a bow-shaped piece or ring 19 for retaining the float, which thus is guided or controlled by the pins 20 and 21. The ring 19 is fixed in a holder 23 having a circular outer cross-section, wherein the inflow and outflow channels 10 and 11 are bored or drilled and provided with connection nipples 17 and 18.
The holder is movably attached to the fastener 22 and is fixed tightly against it by means of an O-ring 24. The fastener 22 is fitted in the usual manner in the top of the container by means of a screw thread. Because the holder 23 is movable in the fastener 22, the holder can be adjusted in such a way that the suitable position is obtained for the tube or hose couplings 17 and 18.
Openings can also be made in the cover of the container for the control of the temperature and the density of the electrolyte.

For example, the bowl in which the inflow and outflow tubes terminate may be placed elsewhere than dlrectly on the upper side of the float, and the control and placing of the float may also be different from the description given above.
