Problems solved by technology

However, although the USB-PD fast charging solution charges fast, it inevitably leads to high power consumption. For applications that charge 8 or even 10 devices at the same time in schools, companies, libraries and other office and learning places, It may cause the power supply load to be too high, causing tripping and other conditions to affect the normal and safe power consumption of the place. Therefore, there is an urgent need for an intelligent dynamic power distribution charging device that can charge multiple devices at the same time and control their power stability.

Embodiment 1

[0036] Such as figure 1 In this embodiment, an expandable intelligent dynamic power distribution charging device includes an AC-DC module, a control module, a plurality of charging modules, and electronically controlled switches connected to the charging modules in one-to-one correspondence.

[0037] Further, the control module at least includes an MCU, an ADC module and an LDO for supplying power to the MCU, the ADC module and the electric control switch.

[0038] Further, the AC-DC module is used to convert the 220V AC power of the mains into DC power for the charging module and the LDO on the control module.

[0039] Further, the electric control switch is controlled by the control module to control the connection between the charging module and the AC-DC module.

[0040] Further, the charging module adopts the USB-PD protocol, and is connected to an external charging device through a USB interface for charging.

[0041] Further, the ADC module includes a current-voltage ...

Embodiment 2

[0043] On the basis of Embodiment 1, this embodiment further proposes a scalable intelligent dynamic power allocation charging method, including the following steps:

[0044] S1. Start the system;

[0045] S2. Turn on the electric control switches one by one from one direction, and keep the state of the electric control switches that have been turned on;

[0046] S3. Calculate the total power of the charging module opened by the MCU, the total power of the charging module is the current value collected by the ADC module * the voltage value supplied to the charging module, and judge whether the total power of the charging module meets the set judgment Conditions, the judgment conditions are as follows:

[0047] A. Whether the total power of the charging module is below the rated power;

[0048] B. Whether the difference between the total power of the charging module and the rated power can charge a new device with the maximum power;

[0049] When the judgment conditions A ...

Embodiment 3

[0059] On the basis of Embodiment 2, this embodiment discloses an optimized practical scalable intelligent dynamic power distribution charging device for charging students' computers at school. The MCU of this charging device adopts STM32 series single-chip microcomputers, and The single-chip microcomputer integrates multiple ADC interfaces, so the ADC module does not use an additional ADC chip. The ADC module is only used to convert the current output by each charging module into a voltage signal of about 1.6V that can be input to the ADC interface of the microcontroller. After the MCU receives the voltage signal, it converts it into a digital signal, and performs inverse calculation and processing inside the MCU to obtain the current value. The current is multiplied by the voltage supplied to the charging module, and the power consumed by the charging module can be estimated. The power consumed by the charging module includes charging The power consumed by the module itself ...

Description

technical field [0001] The invention relates to the field of charging devices, in particular to an expandable intelligent dynamic power distribution charging device and method. Background technique [0002] With the popularity of USB Type-C, more and more devices (mobile phones, tablets, monitors, workstations, chargers, etc.) use the USB-PD fast charging solution. However, although the USB-PD fast charging solution charges fast, it inevitably leads to high power consumption. For applications that charge 8 or even 10 devices at the same time in schools, companies, libraries and other office and learning places, It may cause the power supply load to be too high, causing tripping and other conditions to affect the normal and safe power consumption of the place. Therefore, there is an urgent need for an intelligent dynamic power distribution charging device that can charge multiple devices at the same time and control their power stability.
