[0030] refer to Figures 1 to 5 A novel DC system charging power supply device, comprising:

[0031] The input rectifier unit is used to convert AC power to DC power.

[0032] The intelligent voltage divider unit is connected to the output terminal of the input rectifier module. By dynamically adjusting the ratio of the internal resistor network, it enables the adaptive charging of DC devices with different voltage levels.

[0033] The DC-DC conversion unit is connected to the output terminal of the intelligent voltage divider unit and is used to convert the adjusted DC voltage into a stable charging voltage and output it to the charging interface.

[0034] The feedback adjustment unit monitors the charging current and charging voltage respectively, and feeds back the monitoring data to the intelligent voltage divider unit in real time. The intelligent voltage divider unit adjusts the working state of the DC-DC conversion unit according to the feedback data.

[0035] In this embodiment, by dynamically adjusting the ratio of the internal resistance network through the intelligent voltage divider unit, the device can adapt to the charging needs of DC devices with different voltage levels. Whether it's a high-voltage or low-voltage DC device, this charging device can be used, greatly expanding its applicability. The feedback adjustment unit monitors the charging current and voltage in real time and feeds the monitoring data back to the intelligent voltage divider unit. This real-time feedback mechanism ensures that any abnormal changes during the charging process can be quickly detected. The intelligent voltage divider unit then adjusts the operating state of the DC-DC conversion unit to maintain the stability of the charging process. The intelligent voltage divider unit precisely adjusts the operating state of the DC-DC conversion unit based on the feedback data, ensuring that the charging voltage and current remain within the optimal range, thereby improving charging efficiency.

[0036] Preferably, the input rectifier unit includes:

[0037] A bridge rectifier circuit is used to convert AC power to DC power.

[0038] Filter capacitors are used to smooth out ripple during the charging process.

[0039] In this embodiment, the bridge rectifier circuit utilizes a bridge structure composed of four diodes to achieve efficient conversion from AC to DC power. This conversion not only ensures unidirectional current flow but also effectively utilizes each half-cycle of the AC power through the alternating conduction of the diodes, improving energy conversion efficiency. The addition of a filter capacitor plays a crucial role in smoothing ripple during the charging process. Although the AC power is converted to DC after bridge rectification, it still contains a certain pulsating component, i.e., ripple. The filter capacitor, through its charging and discharging characteristics, can absorb and release these pulsating components, making the output voltage more stable and reducing the impact on subsequent circuits. The combination of the bridge rectifier circuit and the filter capacitor not only improves energy conversion efficiency but also enhances the stability of the entire charging circuit. The stable DC output provides a reliable power foundation for the subsequent intelligent voltage divider unit and DC-DC conversion unit, ensuring the smooth progress of the entire charging process. The filter capacitor not only smooths ripple but also protects subsequent circuits from damage caused by overvoltage and overcurrent to a certain extent. When the input voltage or current changes abruptly, the filter capacitor can absorb this extra energy, thereby reducing the impact on subsequent circuits.

[0040] Preferably, the intelligent voltage divider unit includes:

[0041] A voltage divider circuit is used to reduce the input voltage to a voltage level suitable for charging different DC devices;

[0042] The control circuit is used to receive and process data from the current sensor and voltage sensor, and adjust the operating state of the voltage divider circuit according to this data.

[0043] In this embodiment, the voltage divider circuit, through dynamic adjustment of its internal resistor network, can reduce the input voltage to a level suitable for charging different DC devices. This flexible voltage adaptation capability allows the charging device to be widely used in DC devices with various voltage requirements, improving the device's versatility and practicality. The control circuit is responsible for receiving and processing real-time feedback data from the current and voltage sensors. This data reflects the current and voltage status during the charging process. Based on this data, the control circuit precisely adjusts the operating state of the voltage divider circuit to ensure the safety and stability of the charging process. This precise charging control mechanism can avoid potential safety hazards such as overcharging and overcurrent, protecting the health of the device and the battery. Through the dynamic adjustment of the intelligent voltage divider unit, the charging device can provide appropriate voltage and current according to the actual charging needs of the device, avoiding unnecessary energy waste. This efficient energy utilization method not only improves charging efficiency but also extends battery life and reduces user charging costs. It should be noted that the control circuit uses an STM8L chip and its peripheral circuitry.

[0044] Preferably, the control circuit in the intelligent voltage divider unit is also connected to a wireless communication module for remotely receiving charging commands or uploading charging status information to an external monitoring platform.

[0045] In this embodiment, the wireless communication module enables the charging device to remotely receive charging commands. This allows users or administrators to send charging commands, such as starting charging, stopping charging, and adjusting charging parameters, from a location far from the charging device via an external monitoring platform or mobile device. This remote command receiving capability improves the flexibility and convenience of the charging process, making charging management more efficient. The wireless communication module can also upload the charging status information of the charging device to the external monitoring platform in real time. This information includes key parameters such as charging current, charging voltage, charging time, and battery status. By monitoring these parameters in real time, administrators can understand the progress of the charging process and the status of the device, thereby making corresponding adjustments or taking necessary maintenance measures. Through connection with the external monitoring platform, the charging device can achieve a higher level of automation and intelligent management, such as automatically adjusting charging strategies, predicting charging time, and optimizing charging efficiency. These intelligent functions not only improve the reliability and safety of the charging process but also provide users with a more personalized charging experience.

[0046] Preferably, the feedback adjustment unit includes:

[0047] A current sensor is used to monitor the magnitude of the charging current in real time.

[0048] A voltage sensor is used to monitor the charging voltage in real time.

[0049] The signal processing circuit is used to amplify, filter, and perform analog-to-digital conversion on the electrical signals output by the current sensor and voltage sensor.

[0050] In this embodiment, the application of current and voltage sensors enables the feedback regulation unit to monitor the current and voltage levels during the charging process in real time. This real-time monitoring capability provides crucial operational data for the charging device and is fundamental to ensuring the safe and stable operation of the charging process. The signal processing circuit amplifies, filters, and performs analog-to-digital conversion on the electrical signals output by the current and voltage sensors. This process ensures the accuracy and reliability of the data. The amplification circuit enhances the signal strength, the filtering circuit removes noise interference, and the analog-to-digital conversion converts the analog signal into a digital signal, facilitating subsequent digital processing and analysis. The data processed by the signal processing circuit can be quickly received and processed by other parts of the feedback regulation unit (such as the control circuit of the intelligent voltage divider unit). This rapid response mechanism allows the charging device to quickly adjust the charging strategy based on the real-time monitored current and voltage data, ensuring the safety and efficiency of the charging process.

[0051] Preferably, the charging power supply device further includes an indicator light and a buzzer for alarming when a fault is detected, and the indicator light and buzzer are electrically connected to the control circuit respectively.

[0052] In this embodiment, when the charging device detects any fault, such as overcharging, overcurrent, short circuit, or battery abnormality, the control circuit will immediately activate the indicator light and buzzer. The flashing of the indicator light or the illumination of a specific color, as well as the sounding of the buzzer, can quickly attract the user's attention and alert the user that the charging device is currently faulty. The visual and auditory feedback provided by the indicator light and buzzer can help users or technicians quickly locate the source of the fault. Different flashing patterns of the indicator light or the sounding frequency of the buzzer can represent different types of faults, thereby simplifying the fault diagnosis process.
