A charge pump chip is a converter capable of reducing voltage and increasing current, and is used as one of components of a charging module in an electronic device to achieve fast charging. When the charging power exceeds 100W, the capacity conversion loss of the charge pump chip is high, resulting in a rapid increase in temperature of the electronic device. The body of the electronic device being hot affects hand feeling of a user.

In addition, when the temperature in the electronic device is excessively high, the charge pump chip is suppressed from generating heat by reducing the charging current. In this manner, a length of time of charging at a large current is shortened, charging speed is slowed down, and the fast charging experience is affected.

The charging control method and apparatus provided by embodiments of the present invention may be adapted to a charging solution with a charging power of more than 100W. In addition, the length of time of charging at the large current may be extended in a charge only state and a screen-on charging state, and heat generated by charge pump chips may be effectively suppressed, thereby optimizing the user experience.

Before introducing the charging control method provided by embodiments of the present invention, the charging circuit applicable to the charging control method is first described. <FIG> is a schematic diagram of a charging circuit according to an exemplary embodiment.

As illustrated in <FIG>, the charging circuit includes a first circuit board <NUM>, a second circuit board <NUM>, a charge pump chipset, and a control component <NUM>.

The second circuit board <NUM> is provided on the first circuit board <NUM>. The charge pump chip set includes at least two charge pump chips (<NUM>, <NUM>) provided on the first circuit board <NUM> and at least two charge pump chips (<NUM>, <NUM>) provided on the second circuit board <NUM>. <FIG> is an example in which two charge pump chips (<NUM>, <NUM>) are provided on the first circuit board <NUM>, and two charge pump chips (<NUM>, <NUM>) are provided on the second circuit board <NUM>. The charge pump chips on the first circuit board <NUM> and the charge pump chips on the second circuit board <NUM> are arranged in parallel.

In this manner, current distribution is realized by a plurality of charge pump chips connected in parallel, which is beneficial to reduce heat generated by each charge pump chip. In addition, the charge pump chips on the second circuit board <NUM> and the charge pump chips on the first circuit board <NUM> form relatively isolated heat sources, avoiding a local high temperature of the electronic device resulted from concentrated heat generation of the charge pump chips.

The control component <NUM> is connected to the charge pump chips provided on the first circuit board <NUM> and the second circuit board <NUM> to control the charge pump chips to be turned on or off and thereby to control the working state of the charge pump chips. Optionally, the control component <NUM> includes a processor and a temperature detection component. The temperature detection component is configured to detect temperatures of the charge pump chips on the first circuit board <NUM> and the second circuit board <NUM>. The processor is configured to control the charge pump chips on the first circuit board <NUM> and the second circuit board <NUM> to be turned on or off and thereby to control the working state of the charge pump chips based on temperatures of the charge pump chips detected by the temperature detection component.

<FIG> is a flowchart of a charging control method according to an exemplary embodiment. The method is implemented based on the charging circuit provided above. In addition, the charging control method provided by embodiments of the present invention is applicable to the charge only state and the screen-on charging state of the electronic device. The charge only state refers to a pure charging state of the electronic device. In the charge only state, functional modules of the electronic device except the charging module are in a disabled state. The screen-on charging state means that the electronic device is charged in a working state, and the functional modules of the electronic device except the charging module are also in an enabled state.

As illustrated in <FIG>, the charging control method according to the embodiment of the present invention includes the following.

At block S201, one charge pump chip on the first circuit board and at least one charge pump chip on the second circuit board are controlled to be in a working state simultaneously or at the same time.

The charge pump chips on the first circuit board and the second circuit board form two relatively isolated heat sources in an enabled/working state, and the second circuit board is closer to a rear cover or middle bezel of the electronic device than the first circuit board. That is, heat dissipation condition of the second circuit board is better than that of the first circuit board.

Therefore, through a combination of the one charge pump chip on the first circuit board and the at least one charge pump chip on the second circuit board, at least two relatively isolated heat sources are formed in the body of the electronic device. In addition, with the advantage of the good heat dissipation condition of the second circuit board, a local temperature rise in the body of the electronic device is slowed down.

During the charging process, specific implementations of step S201 in the charge only state and the screen-on charging state are different, which will be explained in the following with reference to different situations.

In the charge only state, step S201 includes controlling one charge pump chip on the first circuit board and one charge pump chip on the second circuit board to be in the working state simultaneously or at the same time.

In the charge only state, modules (such as a display screen module, a radio frequency module, most of the circuits of the CPU, and the like. ) with high energy consumption in the electronic device are in a disabled state. At this time, a power supply output of a power supply of the electronic device is negligible. Therefore, using two charge pump chips in the working state meets charging requirements. Optionally, in the charge only state, in order to ensure the charging speed, a maximum charging current outputted by the two simultaneously enabled charge pump chips is 10A.

According to the invention, with continued reference to <FIG>, the two charge pump chips (<NUM>, <NUM>) are provided on the first circuit board <NUM>, and the two charge pump chips (<NUM>, <NUM>) are provided on the second circuit board <NUM>. The charge pump chips on the first circuit board <NUM> and the second circuit board <NUM> are located at four vertices of a quadrilateral, respectively. In step S201, two charge pump chips located on the same diagonal of the quadrilateral are in the working state at the same time. For example, the charge pump chip <NUM> and the charge pump chip <NUM> are in the working state at the same time, and the charge pump chip <NUM> and the charge pump chip <NUM> are in the working state at the same time.

In the charge only state, the charge pump chips in the working state are main heat sources in the body of the electronic device. Therefore, when the two charge pump chips located on the same diagonal line work at the same time, the two charge pump chips form two dispersed heat sources, avoiding the local high temperature in the electronic device.

In the screen-on charging state, step S201 specifically includes controlling one charge pump chip on the first circuit board and at least two charge pump chips on the second circuit board to be in the working state at the same time.

In the screen-on charging state, the electronic device is in a normal use state, and modules such as the radio frequency module and the display screen module are in the working state. At this time, while the battery of the electronic device receives a charging current outputted by the charge pump chips, the battery also outputs a supply current to other enabled functional modules. In the screen-on charging state, in order to ensure the service life of the battery, the maximum charging current outputted by the charge pump chips in the working state may be preferably 5A.

In addition, since there are many heat sources inside the electronic device in the screen-on charging state, a relatively low charging current is used to take into account the heat dissipation capacity of the electronic device itself, thereby avoiding the situation that the charging current must be reduced as temperatures of the charge pump chips rise too fast.

In the screen-on charging state, at least three charge pump chips are switched to the working state at the same time to share the current and to reduce the heat generated by each charge pump chip. In addition, considering that the heat dissipation condition of the second circuit board is better, preferably, the charge pump chips on the second circuit board are switched to the working state. Optionally, when two charge pump chips are provided on the second circuit board, in the screen-on charging state, both the two charge pump chips on the second circuit board are controlled to be in the working state.

With continued reference to <FIG>, after step S201, the method further includes the following.

At block S202, in response to a temperature of a charge pump chip in the working state on the first circuit board being higher than a set threshold, any charge pump chip on the first circuit board with the temperature lower than the set threshold is switched to the working state.

Optionally, the charge pump chip with the lowest temperature on the first circuit board is switched to the working state. In this case, the charge pump chip with the lowest temperature on the first circuit board that is not in the working state is determined based on temperatures of charge pump chips detected by the temperature detection component.

As the working time is extended, the temperature of the charge pump chip in the working state will gradually increase. When the temperature of the charge pump chip in the working state reaches the set threshold, the charge pump chip with the temperature lower than the set threshold is switched to work. In this manner, dynamically distributed heat sources are formed inside the electronic device. With the charge pump chips that work in turn, the local temperature inside the electronic device being too high is avoided, the length of time for the charge pump chips to charge the battery with a large charging current is prolonged, and the charging speed is increased.

Specific implementations of step S202 in the charge only state and the screen-on charging state are different, which will be explained in the following with reference to different situations.

In the charge only state, step S202 includes, in response to the temperature of each of the charge pump chip in the working state on the first circuit board and the at least one charge pump chip in the working state on the second circuit board being higher than the set threshold (which may be set as <NUM> in the charge only state), switching any charge pump chip on the first circuit board with the temperature lower than the set threshold and any charge pump chip on the second circuit board with the temperature lower than the set threshold to the working state.

Taking the situation illustrated in <FIG> as an example, the charge pump chips (<NUM>, <NUM>) on the first circuit board <NUM> and the charge pump chips (<NUM>, <NUM>) on the second circuit board <NUM> are located at four vertices of a quadrangle. In step S201, the charge pump chip <NUM> and the charge pump chip <NUM> work at the same time. In step S202, in response to temperature of each of the charge pump chip <NUM> and the charge pump chip <NUM> is higher than the set threshold, the charge pump chip <NUM> and the charge pump chip <NUM> are turned off and thereby switched to the non-working state, and the charge pump chip <NUM> and the charge pump chip <NUM> are switched to the working state.

In the charge only state, the heat generated by other functional modules is very low, and the charge pump chips in the working state are the main heat sources. At this time, the heat dissipation capacity of the whole electronic device is good. In view of the good heat dissipation condition, even if the temperature of one of the two charge pump chips in the working state is higher than the set threshold of the charge only state, it is impossible that the local temperature of the electronic device is too high. Therefore, the temperature of each of the two charge pump chips in the working state being higher than the set threshold of the charge only state is determined as a trigger condition for switching the charge pump chips. In this manner, under the premise of improving the hand feeling of the user, the length of time of charging the charge pump chips with the large current is further prolonged, and the charging speed is increased.

In the screen-on charging state, step S202 includes, in response to the temperature of the charge pump chip in the working state on the first circuit board being higher than the set threshold (which may be set as <NUM> in the screen-on charging state), switching any charge pump chip on the first circuit board with the temperature lower than the set threshold to the working state, and keeping the at least two charge pump chips on the second circuit board in the working state.

Taking the situation illustrated in <FIG> as an example, two charge pump chips are provided on the first circuit board <NUM> and two charge pumps are provided on the second circuit board <NUM>. In step S201, the charge pump chip <NUM> and the charge pump chips <NUM>, <NUM> are in the working state at the same time. In step S202, in response to the temperature of the charge pump chip <NUM> being higher than the set threshold of the screen-on charging state, the charge pump chip <NUM> is turned off and thereby switched to the non-working state, and the charge pump chip <NUM> and the charge pump chips <NUM>, <NUM> are switched to the working state at the same time.

In the screen-on charging state, at least three charge pump chips are in the working state at the same time, and the charging current is weaker than the charging current in the charge only state. Therefore, the two charge pump chips on the second circuit board generate little heat. For example, the charging current is 5A in the screen-on charging state. When three charge pump chips work at the same time, the current shared by each charge pump chip on the second circuit board is <NUM>. 66A, and thus it is difficult for the temperature of the charge pump chip to increase to the set threshold of the screen-on charging state. In addition, since the first circuit board has other heat sources (functional modules on the first circuit board), the temperature of the charge pump chip on the first circuit board rises quickly.

Based on the above, in the screen-on charging state, the temperature of the charge pump chip on the first circuit board being higher than the set threshold is determined as the trigger condition for switching the charge pump chip.

In addition, the set threshold of the screen-on charging state is higher than the set threshold of the charge only state. In the screen-on charging state, temperatures of the charge pump chips rise relatively quickly due to several heat sources on the first circuit board. Therefore, the set threshold of the screen-on charging state is higher than the set threshold of the charge only state, so as to ensure that there is a reasonable climbing space for the temperature of the charge pump chip on the first circuit board in the screen-on charging state, avoiding frequent switches of the working state of the charge pump chips.

In summary, the charging control method provided by embodiments of the present invention controls different charge pump chips on the first circuit board and the second circuit board to work at different periods of time based on the temperatures of the charge pump chips. In this manner, on the one hand, the length of time for the charge pump chipset to charge the power supply with a large current is prolonged, and the charging speed of fast charging is increased. On the other hand, dynamically distributed heat sources are formed during the charging process to effectively control the heat generation of the charge pump chips and to optimize the user experience.

In addition, it should also be noted that, in step S201, the charge pump chip with the lowest temperature on the first circuit board is controlled as the charge pump chip used for the first time. In this manner, the charge pump chip with the lowest temperature has the largest climbing space for the temperature to rise to the set threshold in step S202, which ensures that the charge pump chip has a long continuous working time, avoids frequent switches, and increases the charging speed.

As the charging proceeds, the heat inside the electronic device gradually accumulates, and the temperatures of the charge pump chips also gradually increase. In an implementation of the present invention, when the temperature of each of at least two charge pump chips on the first circuit board is higher than the set threshold, the charging current outputted by the charge pump chips is lowered to reduce the heat generation of the charge pump chips and to protect the battery.

In detail, in the charge only state, in response to the temperatures of each of the at least two charge pump chips on the first circuit board and the at least two charge pump chips on the second circuit board being higher than the set threshold, the charging current outputted by the charge pump chips in the working state is reduced. In the screen-on charging state, in response to the temperature of each of the at least two charge pump chips on the first circuit board being higher than the set threshold of the screen-on charging state, the charging current outputted by the charge pump chips in the working state is reduced.

There is no specific limit to a reduction extent of the charging current.

Illustratively, the screen-on charging state is taken as an example. When the temperature of each of the at least two charge pump chips on the first circuit board is higher than the set threshold, the charging current is directly reduced to a safe current (for example, 2A). In this manner, the heat dissipation effect is optimized and the safety of charging is guaranteed.

The above example only uses the screen-on charging state as an example for description, rather than as a limitation that the example method of reducing the charging current is only applicable to the screen-on charging state.

Illustratively, the electronic device being in the charge only state is taken as an example. The set threshold includes a first threshold and a second threshold. In response to the temperature of each of the charge pump chips on the first circuit board and the second circuit board being higher than the first threshold (for example, <NUM>), the charging current is controlled to be reduced to a first charging current (for example, to be reduced from 10A to 7A). In response to the temperature of each of the charge pump chips on the first circuit board and the second circuit board being higher than the second threshold (for example, <NUM>), the charging current is controlled to be reduced to a second charging current (for example, to be reduced from 7A to 5A).

The above example only uses the charge only state as an example for description, rather than as a limitation that the example method of reducing the charging current is only applicable to the charge only state.

<FIG> is a flowchart of a charging control method according to another exemplary embodiment. In an embodiment, as illustrated in <FIG>, after step S201 and step S202, as charging proceeds, the method further includes the following.

At block S203, in response to the temperature of each of the at least two charge pump chips on the first circuit board and the at least two charge pump chips on the second circuit board being higher than a safe critical threshold, all the at least two charge pump chips on the first circuit board and the at least two charge pump chips on the second circuit board are controlled to be in the working state, and a charging current output by charge pump chips in the working state is reduced to a safe current.

In such a situation, the charge pump chips are in an emergency state. At this time, reducing the heat generation of the charge pump chips is a priority goal. Therefore, by increasing the number of the charge pump chips in the working state, the current shared by each charge pump chip is reduced. In addition, the safe current (for example, 2A) is used as the charging current to further reduce the heat generation of each charge pump chip. In this manner, the temperature of the body of the electronic device is prevented from increasing, avoiding affecting the user experience.

Based on the above charging control method, embodiments of the present invention further provide a charging control apparatus. <FIG> is a block diagram of a charging control apparatus according to an exemplary embodiment.
