The first electrode wire and the second electrode wire of the cell are respectively a positive electrode wire and a negative electrode wire of the cell, and if the first electrode wire is the positive electrode wire, the second electrode wire is the negative electrode wire; and if the first electrode wire is a negative electrode wire, the second electrode wire is a positive electrode wire. The positive wire of each cell is connected with the positive pin of the power manager, and the negative wire of each cell is connected with the negative pin of the power manager, so that the power manager can control the cells in the battery.

For example, the power manager outputs a control signal including row address information of the first row unit cell to the row address decoder, and the row address decoder outputs high level "1" to the first row unit cell (address lines of all unit cells are low level "0" in an initial state), and at this time, the first row unit cell is selected, and the positive electrode line or the negative electrode line of each unit cell in the first row unit cell are connected to the positive electrode or the negative electrode line.
In this way, the plurality of unit cells can be rapidly charged in a low voltage and large current state by being connected in parallel. When the damage of the individual unit battery occurs, the normal operation of the battery is not influenced.
Optionally, the row address decoder 12 is configured to control the row address line 14 of at least one row of the unit cells 11 to be at a high voltage level, so as to control the first voltage output terminal of the at least one row of unit cells to be connected to the first electrode;

When there are many cells, one or more rows may be charged one by one, or one or more columns may be charged one by one.
For example, as shown in fig. 1, the cells are arranged in a matrix, and assuming that the cells are arranged in m rows and n columns in the cell, the number of the cells is m × n.
Setting the column address line of n columns of unit batteries in the battery as high level 1, controlling the negative electrode lines of all the unit batteries to be connected with the negative electrode, and then adding voltage to the positive electrode and the negative electrode of the battery. Control then takes place over the row address lines. The row address line of the first row of elementary cells is first set to high level "1" so that the positive electrode line of the first row of elementary cells is connected with the positive electrode, and the n elementary cells in the first row are charged, as shown in fig. 4.

If a row of unit cells is charged or discharged at a time, regardless of the time for switching when each row of unit cells is charged or discharged, if the time for charging or completely discharging a single unit cell is t, the charging or discharging time of the entire battery is m × t. If a row a of the unit cells are charged or discharged each time, where a is an integer greater than 1, the charging or discharging time of the entire battery is m × t/a, which can shorten the charging or discharging time.

Due to the fact that the battery assembly is contained in the mobile terminal, the mobile terminal can achieve the same beneficial effects as the battery assembly.
Referring to fig. 5, fig. 5 is a flowchart of a method for controlling charging and discharging of a battery according to an embodiment of the present invention, which mainly differs from the above embodiments in that a plurality of cells in the battery are controlled to be charged or discharged, and as shown in fig. 5, the method for controlling charging and discharging of a battery includes the following steps:
step 501, obtaining address information of a target cell in a battery, where the address information includes row address information and column address information, and the target cell is at least one of the batteries.
In this step, the cells may be distributed in a matrix, and each cell may uniquely correspond to one row address information and one column address information, i.e., information indicating the position of the cell in the corresponding row and column in the matrix.

Step 502, outputting a first control signal to the target cell according to the row address information to control a first voltage output end of the target cell to be connected with a first electrode line of the target cell.
In this step, the power manager may output a first control signal, which may include row address information of the target cell, to a row address decoder, and the row address decoder sets a row address line of the target cell to a high level "1", thereby controlling a positive line of the target cell to be connected to a positive electrode or a negative line to be connected to a negative electrode. The first voltage output end may be a positive electrode or a negative electrode, and the first electrode line may be an electrode line corresponding to the first voltage output end.
It should be noted that this step may be performed before step 503, after step 503, or simultaneously with step 503.
Optionally, if all the unit batteries of the target unit battery include a first target battery pack formed by dividing in rows, the first target battery pack includes at least one row of the unit batteries;

In this embodiment, if the target unit cells are distributed in at least two rows, the target unit cells may be grouped in units of rows, and one or more rows of unit cells may be grouped together while one or more rows of unit cells are charged or discharged. When the target unit cells are divided into a plurality of groups, the number of rows including the unit cells in each group may be different. For example, the target unit cells are divided into three groups, a first group including one row of unit cells, a second group including two rows of unit cells, and a third group including three rows of unit cells.
After grouping the target cells, the power manager may output a control signal including all the column address information of the target cells to the column address decoder according to the address information of the target cells, so as to control the second electrode lines of the target cells to be connected to the second voltage output terminal, where the second voltage output terminal may be a positive electrode or a negative electrode, and the second electrode lines may be electrode lines corresponding to the second voltage output terminal. The power manager then sequentially outputs control signals containing row address information of the target battery pack to a row address decoder, and the row address decoder sequentially sets row address lines of the target battery pack to high level "1" so that a positive line of the target elementary battery is connected with a positive electrode or a negative line of the target elementary battery is connected with a negative electrode. The first voltage output end may be a positive electrode or a negative electrode, and the first electrode line may be an electrode line corresponding to the first voltage output end. Thus, the target battery packs can be controlled to be sequentially charged or discharged.
For example, as shown in fig. 1, the cells are arranged in a matrix, and assuming that the cells are arranged in m rows and n columns in the cell, the number of the cells is m × n.
Setting the column address line of n columns of unit batteries in the battery as high level 1, controlling the negative electrode lines of all the unit batteries to be connected with the negative electrode, and then adding voltage to the positive electrode and the negative electrode of the battery.

And setting the row address lines and the column address lines of all the elementary batteries to be low level 0' until the charging of the m-th row elementary batteries is finished, and finishing the charging of the batteries.
In specific implementation, a preset number of unit batteries can be divided into a group according to the distribution condition of the unit batteries so as to improve the charging or discharging speed, and meanwhile, the aging or damage of the unit batteries caused by overhigh temperature in the charging process can be avoided.
It should be noted that, when this step is performed after step 503, it is possible to sequentially charge or discharge a plurality of target battery packs, and it is possible to improve the charging or discharging speed, and at the same time, it is possible to protect the cells from aging or damage due to excessive temperature during the charging process.

In this step, the power manager may output a second control signal, which may include column address information of the target cell, to the column address decoder, and the column address decoder sets the column address line of the target cell to a high level "1" to connect the positive line of the target cell to the positive electrode or the negative line to the negative electrode. The second voltage output end may be a positive electrode or a negative electrode, the second electrode line may also be a positive electrode line or a negative electrode line, and the second voltage output end corresponds to the second electrode line.
When the positive electrode line of the elementary cell is connected with the positive electrode and the negative electrode line is connected with the negative electrode, the elementary cell is charged or discharged, and when the charging or discharging is finished, the row address line and the column address line of the elementary cell are set to be low level 0, so that the charging or discharging of the cell is finished.
Optionally, if all the unit batteries of the target unit batteries include a second target battery pack formed by dividing rows, the second target battery pack includes at least one row of the unit batteries;
the step of outputting a second control signal to the target cell according to the column address information includes:

In this embodiment, when the target unit cells are distributed in at least two rows, the target unit cells may be grouped in units of rows, and one or more rows of unit cells may be grouped into one group while one or more rows of unit cells are charged or discharged. When the target unit cells are divided into a plurality of groups, the number of rows including the unit cells in each group may be different. For example, the target unit cells are divided into three groups, a first group including one column of unit cells, a second group including two columns of unit cells, and a third group including three columns of unit cells.
After grouping the target cells, the power manager may output a control signal including row address information of all the target cells to the row address decoder according to address information of the target cells, so as to control a first electrode line of the target cells to be connected to a first voltage output terminal, where the first voltage output terminal may be a positive electrode or a negative electrode, and the first electrode line may be an electrode line corresponding to the first voltage output terminal. The power manager then sequentially outputs control signals containing row address information of the target battery pack to a row address decoder, and the row address decoder sequentially sets the row address lines of the target battery pack to high level "1" so that the positive electrode line of the target elementary battery is connected with the positive electrode or the negative electrode line of the target elementary battery is connected with the negative electrode. The second voltage output terminal may be a positive electrode or a negative electrode, and the second electrode line may be an electrode line corresponding to the second voltage output terminal. Thus, the target battery packs can be controlled to be sequentially charged or discharged.
In specific implementation, a preset number of unit batteries can be divided into a group according to the distribution condition of the unit batteries so as to improve the charging or discharging speed, and meanwhile, the aging or damage of the unit batteries caused by overhigh temperature in the charging process can be avoided.
It should be noted that, when this step is performed after step 502, sequential charging or discharging of a plurality of target battery packs can be achieved, the charging or discharging speed can be increased, and the cells can be protected from aging or damage due to excessive temperature during the charging process.
Optionally, before the step of obtaining address information of a target cell in a battery, the method further includes:
acquiring a battery state of the battery cell in a preset battery cell state table, wherein the battery state comprises a non-full state and a full state, the non-full state represents that the battery cell is in a state after discharging and before charging, and the full state represents that the battery cell is in a state after charging and before discharging;
if the unit cell is charged, setting the unit cell in the non-full cell state as the target unit cell;
setting the cell in the full charge state as the target cell if the cell is discharged;
after the step of outputting a second control signal to the target cell according to the column address information, the method further includes:
and updating the battery state of the target unit battery in the preset unit battery state table.
In this embodiment, a battery state table may be set and stored in advance, and the state table may include the states of the respective unit batteries. The non-full-charge state is a state in which the battery cell does not start to be charged after being discharged for a certain time, and can be represented by a low level "0", and the non-full-charge state can also include an initial state in which the battery cell is not charged for the first time; the fully charged state indicates a state in which the discharge has not started after a certain charge, and is indicated by a high level "1". If the battery needs to be charged, only the address information of the cell in the non-full-power state needs to be acquired, and the cell in the non-full-power state is controlled to be charged; if the battery is required to be discharged, only the address information of the full-charge state cell needs to be acquired, and the full-charge state cell is controlled to be discharged. After the battery charging or discharging is completed, the battery state of the target unit battery may be updated into the battery state table, so that the power manager acquires the target unit battery for charging or discharging according to the latest battery state.
Thus, the charging and discharging speed of the target unit cell can be increased, and when some unit cells are damaged, other unit cells are not influenced, so that the normal operation of the cell is not influenced.
Optionally, the battery state further includes a damaged state, and before the step of obtaining the battery state of the cell in the preset cell state table, the method further includes:
judging whether a damaged cell exists in the battery;
and if the damaged cell exists, identifying the damaged cell as a damaged state in the preset cell state table according to the address information of the damaged cell.
In this embodiment, the damaged cell may be a cell that is incapable of being charged or discharged, for example, a cell whose amount of electricity does not change during charging, and the damaged cell may be represented by a negative level "-1". If there is the elementary battery of damage, can add the sign with the elementary battery of damage in elementary battery state table to make power manager select the elementary battery of damage earlier before charging to the battery, like this, the elementary battery of damage does not participate in the work of charging or discharging, can not cause the influence to the work of other elementary batteries, can not influence the normal work of battery, and can improve and charge and discharge efficiency. The state table of the battery cells can contain the full-charge state, the non-full-charge state and the damage state of the battery cells, and the battery manager can calculate the actual capacity and the residual capacity of the battery cells by counting the number of the battery cells in each state, thereby being beneficial to battery management.
Optionally, after the step of identifying the damaged cell as the damaged state in the preset cell state table according to the address information of the damaged cell, the method further includes:
acquiring the number of the elementary batteries in the damaged state according to the preset elementary battery state table;
and calculating the battery capacity of the battery according to the number of the damaged cells and the capacity of the cells.
In this embodiment, the damaged cells may be screened out by presetting the cell states of the cells recorded in the cell state table, acquiring the number of cells that can normally operate, and calculating the total battery capacity of the battery according to the rated capacities of the cells. Therefore, the calculation mode is simple, battery management is facilitated, and energy is saved. The battery capacity is output through the display screen of the mobile terminal, so that a user can master the battery capacity, and whether the battery needs to be replaced or not is judged.
The charging and discharging method of the battery in the embodiment of the invention can be applied to the battery of a mobile terminal, the battery of an automobile and the like.
