DETAILED DESCRIPTION

[0017] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0018] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0019] Embodiment 1: like Figure 1 As shown, a charging method supporting dynamic adjustment of multi-port PD fast charging power includes the following steps: S1, obtaining charging information of multiple connected charging devices and power information of multiple battery packs; S2, dividing the charging equipment into multiple levels of terminals to be charged according to the information to be charged, and dividing the multiple battery packs into multiple levels of power supply terminals according to the power information; S3, connecting the multi-stage charging terminals of the multiple charging devices and the multi-stage power supply terminals of the multiple battery packs using a dynamically adjusted charging power module; S4. The remaining power of the charging devices corresponding to the multi-level charging terminals is arranged from high to low, and the remaining power of the multi-level power supply terminals is arranged from low to high. S5, dynamically adjusting the charging power module to obtain the remaining power of the charging devices and the battery pack on both sides to adjust the charging power; In step S1, the charging information of multiple charging devices includes the remaining power, battery capacity and charging protocol, and the power information of multiple battery packs includes the battery pack discharge port protocol, remaining power, the first over-discharge threshold of the power supply terminal and the second over-discharge threshold of the power supply terminal.

[0020] Further, in step S2, a terminal to be charged at a certain level among the multiple levels of terminals to be charged includes one or more charging devices; Optionally, when the remaining power of two charging devices is the same, the two charging devices are rated as one level; For example, the remaining power of the charging equipment is rated as level 1 if less than 20%, level 2 if 20%-50%, level 3 if 50%-80%, and level 4 if more than 80%, for subsequent optional matching charging of the above levels through the system; Furthermore, a power supply terminal at a certain level in the multi-level power supply terminal includes one or more battery packs; Optionally, when the remaining power of two battery packs is the same, the two battery packs are also rated as one level; For example, the remaining power of the battery pack is rated as level 1 if less than 20%, level 2 if 20%-50%, level 3 if 50%-80%, and level 4 if more than 80%, for subsequent optional matching charging of the above levels through the system; Among them, a battery pack includes at least one battery, electronics, battery pack, etc., which are used to form a battery pack. In addition, if the power supply is directly connected to the power supply through the power cord, the port directly powered by the power cord is also evaluated as a battery pack with a remaining power of always fully charged.

[0021] In steps S3-S5, the matching method between the multi-stage charging terminal and the multi-stage power supply terminal includes the following: The remaining power of one of the multi-level charging terminals increases dynamically, matching the multiple power supply terminals whose remaining power is arranged in descending order; The remaining power of one of the multi-stage charging terminals is dynamically reduced, and the corresponding remaining power is arranged as multiple power supply terminals that increase in sequence.

[0022] For example, when there is only one charging device and the remaining power is less than 20%, a battery pack of any level will be matched, preferably a battery pack greater than 80% or always fully charged; When there are two charging devices, one of which has a remaining power of less than 20% and the other has a remaining power of more than 80%, the charging device with a remaining power of less than 20% is connected to a battery pack with a remaining power of more than 80% or always fully charged through a dynamic adjustment of the charging power module, and the other charging device with a remaining power of more than 80% preferentially matches a battery pack with a remaining power of 20%-50%; When the remaining power of a charging device with less than 20% is charged to more than 80%, the charging power module will be dynamically adjusted to call its charging interface to a battery pack with a remaining power of 20%-50%.

[0023] The reason is that when the remaining power of the battery pack decreases, the internal resistance of the battery increases, resulting in a decrease in its internal voltage and charging efficiency. If the internal current is forced to be transmitted to the charging device, it will be affected by the resistance and the charging efficiency will also be reduced. When the remaining power of the battery is sufficient, its internal voltage and current are stable, and the charging protocol can be matched to achieve the ideal fast charging effect. Therefore, by charging the low-power battery pack to the charging device that is about to be fully charged, the use of low voltage and low current charging can effectively improve the utilization of electric energy, and dynamic power output can be achieved by dynamically adjusting the charging power module to avoid over-discharge of the battery pack and ensure the safety of the battery pack. In addition, by charging the high-power battery pack to the low-power charging device, the fastest protocol charging speed can be achieved, which can avoid waste in the power transmission process and improve charging efficiency.

[0024] In addition, in order to avoid over-discharge of the battery pack, a first over-discharge threshold and a second over-discharge threshold are set for the power supply terminal. For example, when the battery pack's power reaches 20%, the first over-discharge threshold prompt is triggered and charging is stopped. If an emergency occurs, the first over-discharge threshold permission is enabled to allow the power to be over-discharged to the second over-discharge threshold, or exceed the second over-discharge threshold, thereby protecting the battery life.

[0025] In addition to the above-mentioned adjustment method, the dynamically adjustable charging power module is also used to power the charging equipment in an emergency state through its series interface with multiple battery packs, and the parallel state of the above-mentioned dynamically adjustable charging power module is a plurality of parallel connection positions as independent interfaces. For example, the independent connection and disconnection of multiple independent battery packs, or the parallel connection of multiple independent battery packs can be realized by dynamically adjusting the circuit board where the charging power module is located.

[0026] Embodiment 2: See attached Figure 2 The method for dynamically adjusting the charging power module to dynamically adjust the dynamic adjustment between the multi-stage charging terminal and the multi-stage power supply terminal includes the following steps: S6. Obtain the quantitative relationship between the number of current charging devices and the battery pack, and obtain power information respectively; S71, arranging the remaining power of the multi-level terminals to be charged in the charging information in order from low to high, and setting the corresponding ports of the terminals to be charged; S72, arranging the remaining power of the multi-level power supply terminals in the power information in descending order, and setting the corresponding power supply terminal ports; S8. The charging power module is dynamically adjusted to connect the charging terminal ports in the above arrangement state to the power supply terminal ports accordingly.

[0027] Specifically, the connection methods include: Method 1: The terminal ports to be charged are arranged from low to high and the power supply terminal ports are arranged from high to low in a step-by-step manner. At this time, the charging efficiency is as follows: the power supply terminal port with high power charges the terminal port to be charged with low power, and the charging power is fully charged according to the protocol of the terminal port to be charged. At this time, the power supply terminal port with low power charges the terminal port to be charged with high power, and the charging power is slowly charged according to the protocol of the terminal port to be charged, the remaining required full power and the first over-discharge threshold of the power supply terminal; Method 2: When a new terminal to be charged is connected, it is connected to a power supply terminal in an undischarged state, and the power information of the terminal to be charged is obtained, and the charging method according to method 1 is dynamically adjusted; Method 3: The port of the terminal to be charged corresponds to any port of the power supply terminal, and the terminal to be charged is charged according to the acquired port protocol of the terminal to be charged and the remaining required full power until the first over-discharge threshold of the power supply terminal is reached. When the charging terminal is in the over-discharge state, the charging is stopped, and the remaining power supply terminals are connected to realize continuous charging; Method 4: Any charging method from Method 1 to Method 3: When in the emergency power supply state, after multiple power supply terminals are at the first over-discharge threshold, start the emergency power supply of the remaining power to make the remaining power of each power supply terminal drop to the second over-discharge threshold state.
