Description
Technical Field
The invention relates to the field of battery charging, in particular to a charging method, a charging device and charging equipment.
Background
Based on the development trend of intelligent machines, batteries are still weak links, and although some super batteries reported by news and batteries of new materials can solve the charging problem in the long term, the possibility of short-term commercial use is not very high. Therefore, the traditional lithium/polymer battery is also needed to be adopted, the battery matched with the recent intelligent terminal is basically 3000mAH, and the common charging scheme is far from meeting the requirement, such as the previous 5V/1A charging, the charging time is as long as 4 hours, even if the 5V/1.5A charging is used later, the simple increase of the current causes the volume of the charger to be too large, the charger is inconvenient to carry, the charging time is still about 3 hours, and the improvement is not obvious. For the important position of the intelligent machine in the life of people, the shorter the charging time is, the better the charging time is. The quick charging is carried out by various manufacturers, the charging is carried out by increasing the current from 1A to 3A or even 4A, and the charging time can be reduced to a certain extent.
However, the disadvantages caused by large current are obvious problems of heat generation, and the semiconductor device is sensitive to temperature, generally 10 ℃ higher temperature, and the service life is reduced by half. In addition, the selection of the device is inconvenient due to the large current, and the design of the ID is influenced due to the fact that the device with the large current is too large. Therefore, the latest scheme adopts a dual-IC (or multi-integrated circuit IC) charging scheme, such as charging current 3A, and each IC charging current only needs 1.5A, which apparently can solve the disadvantages caused by large current.
In the related art, the fast charging scheme is basically used, and the dual-IC parallel charging scheme is used, and the relationship of 2 minutes is basically adopted in the current distribution, that is, the current distributed by each IC is the same. In the parallel charging scheme of the related art, the charging current is distributed according to a fixed proportion, the charging current is written once in the starting process, the system cannot be dynamically adjusted in the running process, and the requirements of different loads cannot be realized, fig. 1 is a schematic diagram of circuit connection in the related art according to the invention, as shown in fig. 1, a DC/USB is two different inputs, namely a DC power supply and a USB power supply, and Vsys is system power. Thus, the existing technology cannot dynamically realize current regulation, and the system stability and the battery life cannot be better embodied.
In view of the above problems in the related art, no effective solution has been found at present.

Fig. 6 is a schematic block diagram of a circuit according to an embodiment of the invention, as shown in fig. 6,

Current detection (block): the charging current of each charging IC is detected. Wherein if the integrated IC itself has a communication interface and a current detection function, the current detection module is not required to be used. For an independent pure module, the communication function and the detection function are not available, and the current detection module is required to report to the main chip.
A main chip: and receiving effective information transmitted by the whole equipment, such as the working condition of each charging IC and the power consumption demand condition of each module, and comprehensively adjusting according to the preset priority.
Optionally, the application scenario of this embodiment may be, but is not limited to, the following:
1. the device has two charging chips, and a battery is charged, so that quick charging is realized.
2. The device has more than two charging chips, and a battery is charged, so that quick charging is realized.
3. The device has two or more charging chips for charging one battery pack.
The implementation scenario of the embodiment includes a scenario where all of the plurality of charging ICs or the plurality of modules are powered.
The first embodiment will be described in detail below, and the second and third embodiments are similar.
In the present embodiment, two charging tube chips are used, one of which is a charging only chip and is set as IC1, and the other is a management chip integrating a charging function and a chip integrating a charging function, and is also set as IC2 for supplying power to the system. The original current distribution is 2 minutes, for example, the maximum charger input current is 2A, and is set as I.
In the initial setup, the input current of both chips is 1A, and the charging current is the same. Later debugging finds that the input current of 1A does not meet the requirements of the system for IC2, and finally the input current is adjusted to 1.5A, and IC1 is adjusted to 0.5A. However, the write setting is completed by one-time setting at the starting time, and cannot be dynamically adjusted in the system operation process.
When the output current of the IC1 is sampled at R1 and the output current of the IC2 is sampled at the resistor R2, the currents flowing through R1 and R2 are positive values and are I1 and I2, respectively, when the input current meets the requirement. I.e. R1I 1 ═ U1, R2I 2 ═ U2. Both U1 and U2 are positive values. If both are positive values, the system is powered normally, and if it is found that U2 is less than 0, the corresponding I2 is adjusted using increments of 0.1A (which may be arbitrary), i.e., Δ I. The current magnitude of I1 is preferably adjusted by using I1(new) ═ I1-N × Δ I, and adjusting I2(new) ═ I2+ N × Δ I until U2 is greater than 0, where N is 1.2.3 ….
If it is found that U2 is always positive, if the comparison is close to U2max (a preset threshold). Then, using the method opposite to the above, the current magnitude is adjusted, assuming that the output current of IC1 is sampled at R1, the output current of IC2 is sampled at resistor R2, and when the input current meets the requirement, the currents flowing through R1 and R2 are positive values, and are respectively set as I1 and I2. Namely, R1 × I1 ═ U1, and R2 × I2 ═ U2. Both U1 and U2 are positive values. If both are positive then the system is powered normally but if it is found that where U2 is greater than 0 and exceeds U2max, the corresponding I2 is adjusted using increments of 0.1A (as may be arbitrary) or Δ I. The current of I1 is preferably adjusted to be large and large by using I1(new) ═ I1+ N Δ I, and I2(new) ═ I2-N Δ I is adjusted until U2 is smaller than U2max, wherein N is 1.2.3 ….
The three implementation cases can be realized by using the technical scheme of the deformation.
Through this embodiment, compare with prior art, can be according to the reasonable distribution charging current of equipment application scene and the electric current of other modules, the bigger degree is favorable to system temperature and improvement battery life.

s71: each relevant module reports demand information, such as current, electric quantity, temperature and power consumption conditions;
s72: the main chip integrally regulates and controls the chip managed by the main chip according to the reported information;
s73: adjusting the current condition of one chip according to the information, then judging whether the result is effective and whether the result reaches the expected result, if the result is satisfied, continuing to wait, and if the result is not satisfied, adjusting the module associated with the result;
s74: if the relevant modules are adjusted and still do not reach the effect, the adjustment strength in the first step is not enough, the adjustment strength is increased, and the effect judgment is still carried out.
