[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0015] Referring to Figures 1-3 , a mobile power supply with stacking interfaces includes a plurality of mobile power supply bodies 1, wherein the power and capacity specifications of each mobile power supply body 1 are the same, and its power and capacity can be 45W / 10000mAh. The plurality of mobile power supply bodies 1 are stacked and assembled up and down. After stacking, the plurality of mobile power supply bodies 1 are connected through a parallel circuit to achieve the cumulative increase of capacity. For example, the total capacity reaches 20000mAh after two 10000mAh mobile power supplies are stacked;

[0016] A stacking interface is installed between two adjacent mobile power supply bodies 1. The stacking interface includes a plurality of POGO PIN pins 102 fixedly arranged on the left side of the top of the mobile power supply body 1 and a plurality of charging PIN pins 101 arranged on the left side of the bottom of the mobile power supply body 1. The charging PIN pins 101 are adapted to the corresponding POGO PIN pins 102. The charging PIN pins 101 are inserted into the corresponding POGO PIN pins 102. A plurality of magnets 2 are fixedly connected to the mutually adjacent sides of two adjacent mobile power supply bodies 1, and the two opposite magnets 2 are attracted to each other.

[0017] This embodiment also proposes an intelligent control circuit for a mobile power supply with stacking interfaces, including an MCU main control chip, a charge and discharge management circuit, a multi-source circuit input / output system, a microcontroller, a charging stacking control detection circuit, and an over-current and over-voltage protection circuit. The charge and discharge management circuit, the multi-source circuit input / output system, the microcontroller, the charging stacking control detection circuit, and the over-current and over-voltage protection circuit are all electrically connected to the MUC main control chip. Among them, the multi-channel power input / output system can ensure that the input and output of each mobile power supply unit can be independently controlled;

[0018] The charging stack control and detection circuit is used to monitor the current and voltage of each mobile power unit in real time, ensuring that they do not exceed the safety threshold and the voltage is stable. Each mobile power unit is integrated with a temperature sensor to monitor the temperature in real time and uses graphene materials for heat dissipation. The microcontroller is equipped with I / O ports, an ADC analog-to-digital converter, and a PWM pulse width modulation. The microcontroller realizes the real-time monitoring and control of current and voltage and the interaction with the user interface by programming firmware.

[0019] The charge and discharge management circuit is electrically connected to the battery. The charge and discharge management circuit can intelligently allocate current according to the remaining power and load demand of each mobile power unit, realizing the charge and discharge management function, ensuring that each unit can be evenly charged during charging and avoiding overcharging and over-discharging.

[0020] The battery is electrically connected to the over-current and over-voltage protection circuit. The over-current and over-voltage protection circuit is used to detect the voltage and current conditions. When the current exceeds the set threshold, the power supply is automatically cut off. In addition, it can also cut off the power supply immediately when a short circuit is detected.

[0021] The charging stack control and detection circuit is electrically connected to a display screen, a stacking interface, and a stacking detection interface. The display screen is used to display the current total power, real-time power, etc.

[0022] The stacking interface is the stacking interface mentioned above, which is composed of multiple POGO PIN pins 102 and multiple charging PIN pins 101. Communication is carried out between the MCU main control chip, the charge and discharge management circuit, the multi-source circuit input / output system, the microcontroller, the charging stack control and detection circuit, the over-current and over-voltage protection circuit, the display screen, the stacking interface, and the stacking detection interface through a communication protocol to realize information exchange. By stacking multiple mobile power bodies 1 through the stacking technology and the stacking interface, the power and capacity of the mobile power can be improved without increasing the volume and weight of a single mobile power, enabling users to flexibly adjust the power and capacity of the mobile power according to their needs, improving the use convenience. And with the setting of the intelligent control circuit, the safety and stability of the stacked mobile power can be ensured to meet the use requirements.

[0023] Working principle: During use, the adjacent two mobile power bodies 1 are stacked through the magnet 2 and the stacking interface. Through the stacking interface and the magnetic attraction fixation method, the accurate docking of the adjacent two mobile power bodies 1 can be realized, ensuring that the electrical interface can transmit sufficient current and voltage. The stacked mobile power bodies 1 can realize the cumulative increase of capacity through a parallel circuit. For example, the total capacity reaches 20000 mAh after two 10000 mAh mobile powers are stacked.

[0024] In addition, an intelligent control circuit is provided. Through communication protocols, it enables data exchange between various units. During use, a charging stack control detection circuit is used to monitor the current and voltage magnitudes of each mobile power supply unit in real time, ensuring that they do not exceed the safety threshold and the voltage is stable. Moreover, each mobile power supply unit is integrated with a temperature sensor to monitor the temperature in real time. When the temperature is high, graphene materials are used for heat dissipation. The microcontroller is used to achieve real-time monitoring and control of current and voltage, as well as interaction with the user interface. The detected information is displayed on the display screen;

[0025] At the same time, the charging and discharging management circuit provided can intelligently allocate current according to the remaining power and load requirements of each mobile power supply unit, realizing the charging and discharging management function, ensuring that each unit can be evenly charged during charging, avoiding overcharging and over-discharging, and detecting the voltage and current conditions and short-circuit conditions through the over-current and over-voltage protection circuit. When the current exceeds the set threshold or a short circuit occurs, the power supply is automatically cut off, thereby improving the safety and stability during the use of the stacked mobile power supply.
