Description

Charging method, device and equipment

technical field

The present invention relates to the field of battery charging, and in particular, to a charging method, device and equipment.

Background technique

Based on the development trend of smart phones, batteries are still a weak link. Although some super batteries and batteries of new materials reported in the news can solve the charging problem in the long run, the possibility of commercial use in the short term is not very large. Therefore, traditional lithium/polymer batteries must be used. The standard batteries of recent smart terminals are basically 3000mAH. The ordinary charging scheme is far from meeting the needs. For example, the previous 5V/1A charging, the charging time is as long as After 4 hours, even if 5V/1.5A is used for charging later, simply increasing the current will cause the charger to be too bulky and inconvenient to carry. The charging time is still about 3 hours, and the improvement is not obvious. For the important role of smartphones in people's lives, the shorter the charging time, the better. Followed by the fast charging introduced by various manufacturers, the essence of charging is to increase the current, from 1A to 3A, or even 4A, which can reduce the charging time to a certain extent.

However, there are various disadvantages caused by high current, and the most obvious one is the problem of heat generation. Semiconductor devices are more sensitive to temperature. Generally, if the temperature is 10 degrees higher, the lifespan will be reduced by half. In addition, the high current also brings a lot of inconvenience to the device selection. The high current device is often too large, which will affect the ID design. Therefore, the latest solutions all adopt dual IC (or multi-integrated circuit (Integrated Circuit)) charging solutions. For example, the charging current is 3A, and the charging current of each IC is only 1.5A. On the surface, it can solve the drawbacks caused by high current.

In the related art, a fast charging scheme is basically used, and a dual IC parallel charging scheme is used, and a 2-point relationship is basically adopted in current distribution, that is, the current distributed by each IC is the same. In the parallel charging scheme of the related art, the distribution of the charging current is allocated according to a fixed ratio, and it is written once during the boot process, and it cannot be dynamically adjusted during the system operation process, and cannot meet the requirements of different loads. Figure 1 is related to the present invention. The schematic diagram of the circuit connection in the technology, as shown in Figure 1, DC/USB are two different inputs, namely DC and USB power supply, and Vsys is the system power. In this way, the existing technology cannot dynamically realize current adjustment, and the system stability and battery life cannot be better reflected.

For the above problems existing in the related art, no effective solution has been found so far.

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

The solution of this embodiment includes a battery, a main chip, multiple power management chips, and some pure charging function circuits (charging IC and integrated charging IC).

Optionally, one or more batteries can be combined in various series-parallel manners. Batteries can include lithium batteries, lithium polymer batteries, and various other batteries that can store electricity.

Charging IC: A chip with a simple charging function, which can be a simple step-down circuit or a DC source.

Integrated charging IC: provide external power supply while providing charging function, or integrate other management functions.

Current detection (module): Detect the charging current of each charging IC. Among them, if the integrated IC itself has a communication interface and a current detection function, it is not necessary to use a current detection module. For an independent pure module without communication function and detection function, the current detection module needs to be reported to the main chip.

Main chip: Receive the effective information transmitted by the device as a whole, such as the working status of each charging IC and the power consumption demand of each module, and adjust it according to the preset priority.

Optionally, the application scenarios of this embodiment may be but are not limited to the following:

1. The device has two charging chips to charge a battery to achieve fast charging.

2. The device has more than two charging chips to charge one battery to achieve fast charging.

3. The device has two or more charging chips to charge one battery pack.

The implementation scenario of this embodiment includes all scenarios in which multiple charging ICs or multiple modules supply power.

The first implementation case is described in detail below, and the second and third are similar.

The two charging tube chips used in this embodiment, one is a chip for charging only, set as IC1, and the other is a management chip with integrated charging function, and the integrated function chip will also supply power to the system, set as IC2 . The original current distribution is a relationship of 2 points. For example, the maximum input current of the charger is 2A, which is set to I.

In the initial setup, the input current of both chips is 1A, and the charging current is the same. After debugging, it was found that for IC2, the input current of 1A did not meet the needs of the system, and was finally adjusted to 1.5A, and IC1 was adjusted to 0.5A. However, the writing settings are all set at one time when the system is powered on, and cannot be dynamically adjusted during system operation.

Suppose the output current of IC1 is sampled at R1, and the output current of IC2 is sampled at resistor R2. If the input current meets the requirements, the currents flowing through R1 and R2 are positive values, which are set as I1 and I2 respectively. That is, R1*I1=U1, R2*I2=U2. Both U1 and U2 are positive values. If both of them are positive, the system is powered normally. If U2 is found to be less than 0, adjust the corresponding I2, using an increment of 0.1A (which can be arbitrary), that is, ΔI. Priority is given to adjusting the current of I1, using I1(new)=I1-N*ΔI, and adjusting I2(new)=I2+N*ΔI until U2 is greater than 0, where N is 1.2.3….

If it is found that U2 is always positive, if it is relatively close to U2max (preset threshold). Then use the opposite method to the above to adjust its current size. Set the output current of IC1 to sample R1, and the output current of IC2 to sample resistor R2. When the input current meets the requirements, the current flowing through R1 and R2 is a positive value. Set as I1, I2 respectively. That is, R1*I1=U1, R2*I2=U2. Both U1 and U2 are positive values. If both are positive, the system is powered normally, but if it is found that U2 is greater than 0 and exceeds U2max, adjust the corresponding I2, using an increment of 0.1A (can be arbitrary), that is, ΔI. Priority is given to adjusting the current of I1, using I1(new)=I1+N*ΔI, and adjusting I2(new)=I2-N*ΔI until U2 is less than U2max, where N is 1.2.3….

For the above three implementation cases, all of them can be implemented by using their variant technical solutions.

Through this embodiment, compared with the prior art, the charging current and the currents of other modules can be reasonably allocated according to the application scenario of the device, which is beneficial to the system temperature and the improvement of battery life to a greater extent.

FIG. 7 is a basic flow chart of current adjustment according to an embodiment of the present invention, as shown in FIG. 7 , including:

S71: Each related module reports demand information, such as current, power, temperature and power consumption;

S72: The main chip conducts overall regulation of the chips under its jurisdiction according to the reported information;

S73: Adjust the current condition of one of the chips according to the information, and then judge whether the result is valid and whether it reaches the expected result. If the result is satisfied, continue to wait, and if the result is not satisfied, adjust the module associated with it;

S74: If adjusting its related modules still fails to achieve its effect, it means that the adjustment strength in the first step is not enough, increase the adjustment strength, and still carry out the effect judgment.

In this embodiment, when the device has multiple charging chips, the size of the load current is reasonably arranged according to the application scenario. When the device has multiple battery packs, the current can be distributed reasonably according to the overall environment of the device (power consumption of the whole machine, heat generation).
