Example one
An embodiment of the present invention provides a charging control method, please refer to fig. 1, which is a schematic flow chart of the charging control method according to the embodiment of the present invention, and as shown in the figure, the method includes the following steps:
101. the method comprises the steps of collecting the temperature of a first charging circuit and the temperature of a second charging circuit in the process of simultaneously charging a battery by utilizing the first charging circuit and the second charging circuit, wherein the current of the first charging circuit is larger than that of the second charging circuit.
In the embodiment of the invention, after the connection with the specified type of charger is detected, for example, when the electronic device detects that a quick-charging charger is inserted, the battery in the electronic device is charged simultaneously by using the first charging circuit and the second charging circuit according to the current of the default configuration. In this embodiment, a current of the first charging circuit is greater than a current of the second charging circuit, which is taken as a default configuration as an example for illustration.
Further, in the process of simultaneously charging the battery by using the first charging circuit and the second charging circuit, the temperature T _ board of a main board in the electronic device where the battery is located, the temperature T _ charge 1 of the first charging circuit and the temperature T _ charge 2 of the second charging circuit are collected.
For example, the current T _ charge 1 of the first charging circuit is 2.4A, and the current T _ charge 2 of the second charging circuit is 1.2A.
For example, the main board of the electronic device in which the battery is located may be the main board in which the first charging circuit and the second charging circuit are located.
Referring to fig. 2, which is an exemplary diagram of charging a battery by using a first charging circuit and a second charging circuit simultaneously according to an embodiment of the present invention, as shown in fig. 2, two charging circuits, i.e., a first charging circuit and a second charging circuit, are disposed in a motherboard, one end of each charging circuit is connected to a charger, and the other end is connected to the battery, and related control of the charging circuits is implemented by a control chip (not shown) in an electronic device.
In a possible implementation, the collecting of the temperature of the main board, the temperature of the first charging circuit, and the temperature of the second charging circuit may be performed periodically during the charging process, or may be performed periodically at a specified time interval during the charging process, which is not particularly limited in the embodiment of the present invention.
102. Detecting whether the temperature of the first charging circuit and the temperature of the second charging circuit satisfy a specified switching condition.
In the embodiment of the invention, after the temperature of the mainboard, the temperature of the first charging circuit and the temperature of the second charging circuit are collected, whether the temperature of the mainboard, the temperature of the first charging circuit and the temperature of the second charging circuit meet the specified switching condition or not is detected.
In one possible embodiment, a difference between the temperature T _ charge 1 of the first charging circuit and the temperature T _ board of the main board is calculated as the first difference Δ T _ 1. And calculating the difference between the temperature T _ charge 2 of the second charging circuit and the temperature T _ board of the main board as a second difference delta T _ 2.
Further, the first difference Δ T is compared1Obtaining a first comparison result with a preset first threshold value Limit High _ 1; and comparing the second difference value Δ T2And obtaining a second comparison result with a preset second threshold value Limit High _ 2.
In a possible embodiment, the first threshold Limit High _1 and the second threshold Limit High _2 may be set in advance according to the characteristics of the circuit, as the threshold values for the charging strategy conversion. The first threshold Limit High _1 is used as a threshold value corresponding to the first charging circuit, and the second threshold Limit High _2 is used as a threshold value corresponding to the second charging circuit.
Further, the first difference Δ T is compared1And a second difference DeltaT2。
It should be noted that if the first difference Δ T is smaller than the first threshold value Δ T1Greater than the second difference Δ T2The first charging circuit is a main cause of heat generation of the main board. Conversely, if the first difference Δ T is1Less than a second difference Δ T2The second charging circuit is a main cause of heat generation of the main board.
With the charging process, the device in the charging circuit, such as the charging chip, will generate heat continuously when the first difference Δ T1Greater than the second difference Δ T2And the second comparison result is a second difference Δ T2When the temperature is less than the second threshold Limit High _2, it is determined that the temperature of the motherboard, the temperature of the first charging circuit, and the temperature of the second charging circuit satisfy the specified switching condition.
Conversely, if the first difference Δ T is1Less than or equal to the second difference Δ T2Or, if said first difference Δ T is1Greater than the second difference Δ T2And the second comparison result is the second difference Δ T2And if the temperature is larger than or equal to the second threshold value Limit High _2, judging that the temperature of the mainboard, the temperature of the first charging circuit and the temperature of the second charging circuit do not meet the specified switching condition.
The first difference Δ T1Less than or equal to the second difference Δ T2Two cases are included:
first, first difference value DeltaT1Less than or equal to the second difference Δ T2Said first difference Δ T1Is smaller than a preset first threshold value Limit High _ 1.
Second, first difference DeltaT1Less than or equal to the second difference Δ T2Said first difference Δ T1Greater than or equal to a preset first threshold Limit High _ 1.
103. When the temperature of the first charging circuit and the temperature of the second charging circuit meet a specified switching condition, the current of the first charging circuit is reduced, and the current of the second charging circuit is increased.
In the embodiment of the present invention, when the temperature of the first charging circuit and the temperature of the second charging circuit satisfy the specified switching condition, a charging conversion policy needs to be executed, that is, the current of the first charging circuit is greater than the current of the second charging circuit, and the current of the first charging circuit is converted to be less than the current of the second charging circuit. The charging conversion strategy may be implemented by turning down the current of the first charging circuit and turning up the current of the second charging circuit. As the current of the first charging circuit decreases, the temperature of the first charging circuit also decreases.
For example, before the transition, the current T _ charge 1 of the first charging circuit is 2.4A, and the current T _ charge 2 of the second charging circuit is 1.2A. After the conversion, the current T _ charge 1 of the first charging circuit becomes 1.2A, and the current T _ charge 2 of the second charging circuit becomes 2.4A. After the conversion, the current of the second charging circuit is larger than that of the first charging circuit, at the moment, the second charging circuit is used as a main charging circuit, and the first charging circuit is used as an auxiliary charging circuit.
In the embodiment of the invention, when the temperature of the first charging circuit and the temperature of the second charging circuit do not meet the specified switching condition, the current of the first charging circuit and the current of the second charging circuit are kept unchanged.
In the embodiment of the present invention, after the current of the first charging circuit is decreased and the current of the second charging circuit is increased, step 101 is executed, so that the temperature of the second charging circuit will continuously increase, when the first difference Δ T is smaller than the second difference Δ T1Greater than the second difference Δ T2And the first comparison result is a first difference value DeltaT1When the temperature of the first charging circuit is lower than the first threshold value Limit High _1, the second charging circuit is the main reason causing the heating of the mainboard, the temperature of the first charging circuit and the temperature of the second charging circuit are judged to meet the specified switching condition, then the current of the first charging circuit is increased, and the current of the second charging circuit is decreased, so that the first charging circuit and the second charging circuit are circularly switched as a main charging circuit and an auxiliary charging circuit, when the temperature of one charging circuit is higher, the current of the charging circuit is decreased, the current of the other charging circuit is increased, when the temperature of one charging circuit is higher, the temperature of the charging circuit is decreased by decreasing the current of the charging circuit, and simultaneously, the current of the other charging circuit is increased in order to avoid the problem of charging speed reduction caused by the current reduction, therefore, the charging speed is ensured, and the problems that the device is damaged due to overhigh temperature, even the whole electronic equipment is burnt out and the life safety of a consumer is seriously dangerous caused by the overheating of the charging circuit are avoided.
It should be noted that the electronic device according to the embodiments of the present invention may include, but is not limited to, a Personal Computer (PC), a Personal Digital Assistant (PDA), a wireless handheld device, a Tablet Computer (Tablet Computer), a mobile phone, a wearable device, and the like.
The execution bodies 101 to 103 may be charging control devices, and the charging control devices may be located in electronic equipment.

Referring to fig. 3, another flow chart of the charging control method according to the embodiment of the invention is shown, as shown in fig. 3, the method includes:
301. when the insertion of the quick charging charger is detected, the battery in the electronic device is charged by the charging circuit 1 and the charging circuit 2 at the same time according to the default configuration current, the current T _ charge 1 of the charging circuit 1 is 2.4A, and the current T _ charge 2 of the charging circuit 2 is 1.2A.
The charging circuit 1 is a main charging circuit, and the charging circuit 1 is an auxiliary charging circuit.
302. The temperature T _ board of a main board in the electronic equipment where the battery is located, the temperature T _ charge 1 of the charging circuit 1 and the temperature T _ charge 2 of the charging circuit 2 are collected.
303. Calculating the difference between the temperature T _ charge 1 of the charging circuit 1 and the temperature T _ board of the main board to obtain a first difference value delta T _1, and calculating the difference between the temperature T _ charge 2 of the charging circuit 2 and the temperature T _ board of the main board to obtain a second difference value delta T _ 2.
304. The magnitude of the first difference Δ T _1 is compared with the magnitude of the second difference Δ T _ 2. If the first difference Δ T _1 is greater than the second difference Δ T _2, step 305 is performed. On the contrary, if the first difference Δ T _1 is less than or equal to the second difference Δ T _2, step 301 is executed to keep the present current of the charging circuit 1 and the present current of the charging circuit 2 unchanged.
305. And judging whether the second difference value Δ T _2 is smaller than a second threshold Limit High _2, if so, executing step 306, and if not, executing step 301, namely keeping the current of the charging circuit 1 unchanged and keeping the current of the charging circuit 2 unchanged.
306. The current T _ charge 1 of the charging circuit 1 was adjusted to 1.2A, and the current T _ charge 2 of the charging circuit 2 was adjusted to 2.4A.
