[0057] To make the objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0058] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0059] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1

[0060] Reference Figure 1 , Figures 3-7 , Figures 12-17 This is the first embodiment of the present utility model. This embodiment provides a fast emergency intelligent charging and testing device for power supply in high-altitude and cold environments without disassembly. It can realize the effect of charging the power supply DC on the spot in the field without disassembly and fast charging, simplifying the charging operation and maintenance of the storage battery 300. It includes a DC charging module 101 that uses the output voltage of the vehicle generator to charge the storage battery 300 and an emergency unit 200.

[0061] Specifically, the emergency unit 200 is used to control the charging process of the multi-channel batteries 300. The emergency unit 200 includes a charging control circuit 202, a CPU module 201, a voltage detection circuit 203, a current detection circuit 204, and an emergency power supply circuit 205. Under the control of the CPU module 201, the charging control circuit 202 outputs a PWM signal to control the on / off duty cycle of the solid-state relay 400 to realize the charging control of the batteries 300. The CPU module 201 realizes functions such as charging control, current and voltage monitoring, and switch signal control. The voltage detection circuit 203 and the current detection circuit 204 detect the voltage and charging current of the batteries 300 respectively and input the signals to the CPU module 201. When the capacity of the vehicle batteries 300 is insufficient, the emergency power supply circuit 205 uses the vehicle body batteries 300 as the vehicle power supply and can start the vehicle body generator.

[0062] Furthermore, the DC charging module 101 is used to charge the battery 300 using the output voltage of the vehicle generator. The DC charging module 101 includes a DC-DC power conversion submodule 101a, an input control circuit 101b, an input filter circuit 101c, and a DC conversion submodule 101d. The DC-DC power conversion submodule 101a converts the output voltage of the vehicle generator into a stable and adjustable charging voltage. The input control circuit 101b controls the input of the vehicle generator output voltage. The input filter circuit 101c eliminates spike pulses and ripple voltages in the generator output voltage. The DC conversion submodule 101d converts the input dynamic voltage into a stable and adjustable PWM pulse charging voltage.

[0063] Furthermore, the DC-DC power conversion submodule 101a uses the CDS6002428 model from COSEL Corporation of Japan. Its input voltage range is 18VDC to 36VDC, and its output voltage is 28VDC and adjustable, with a maximum output power of 600W. Ripple and noise are controlled to ≤150mV. This module acts as a voltage converter, transforming the output voltage of the vehicle's alternator into a stable voltage suitable for charging the 300mAh battery.

[0064] The input control circuit 101b consists of a high-power input fuse F3, a high-power contactor K5 (using a domestically produced JQ-41F type small contactor with a resistive load range of 1-50A, a maximum switching power of 1400W, a contact resistance ≤50mΩ, a coil power consumption ≤2.7W, and an operating time ≤15ms), a protection diode D43, and a DC power supply control switch S4. This circuit is mainly responsible for controlling the input of the car alternator's output voltage, acting like a "gate" that opens when charging is needed and closes when not.

[0065] Preferably, the input filter circuit 101c consists of an absorption circuit composed of a common-mode inductor, two X capacitors, two Y capacitors, and a transient voltage suppressor 1.5KE36A. Its function is to eliminate the 100V pulse voltage generated by the generator, acting like a "filter" to remove impurities in the voltage and protect subsequent circuits.

[0066] Preferably, the DC-DC conversion submodule 101d is based on the power conversion module N17, and includes components such as the digital potentiometer N15, output filter capacitors C59 and C62, and reverse protection diode D42. The power conversion module N17 converts the input 24V dynamic voltage into a stable and adjustable 28V charging voltage. The parameters of the digital potentiometer N15 can be adjusted by the CPU module 201 through three control signal lines, thereby changing the output voltage of the DC-DC power conversion submodule 101a, acting like a "regulator" to allow the output voltage to be adjusted according to demand.

[0067] Working principle: When the vehicle starts, the vehicle's generator begins to work and generate output voltage. This voltage first passes through the input control circuit 101b, and the operator controls the circuit's on / off state via the DC power supply control switch S4. Once the circuit is connected, current flows into the input filter circuit 101c, where components such as the common-mode inductor, X capacitor, and Y capacitor begin to filter the voltage, removing interference factors such as spike pulses and ripple voltage.

[0068] The filtered and stabilized voltage is sent to the DC-DC conversion submodule 101d. Here, under the command of the CPU module 201, the power conversion module N17 converts the dynamic 24V voltage into a stable and adjustable 28V charging voltage according to the settings of the digital potentiometer N15. This converted voltage is further stabilized by the output filter capacitors C59 and C62, and then output through the reverse protection diode D42 to charge the battery 300.

[0069] When the vehicle is driving in the field and the 24V battery 300 is found to be low on power, the DC charging module 101 is activated. The 24V voltage generated by the vehicle's alternator, after the above series of conversions and processing, finally charges the battery 300 with a stable 28V voltage. The charging current is automatically adjusted according to the actual situation of the battery 300, achieving fast and stable charging. This eliminates the cumbersome operation of removing the battery 300 for charging and improves the vehicle's mobility and operational efficiency in the field. Example 2

[0070] Reference Figure 1 , Figure 3 , Figures 8-17 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an AC charging module 102, which solves the problems of on-site charging of AC power supply in the field, no disassembly required, and fast charging.

[0071] Specifically, the AC charging module 102 is used to charge the battery 300 using 220V AC mains power. The AC charging module 102 includes an AC power supply conversion submodule 102a, an AC rectifier and filter circuit 102b, a high-voltage DC input filter circuit 102c, and a high-voltage step-down submodule 102d. The AC power supply conversion submodule 102a converts 220V AC into a stable charging voltage output. The AC rectifier and filter circuit 102b converts the input AC into a pulsating DC voltage and filters it. The high-voltage DC input filter circuit 102c eliminates electromagnetic interference in the AC mains power. The high-voltage step-down submodule 102d converts the high-voltage DC into the required charging voltage.

[0072] Furthermore, the AC power conversion submodule 102a uses the DBS700B12 and DBS700B28 models from COSEL Corporation of Japan. Its input voltage is 200VDC~400VDC, the output voltage is adjustable to 24V or 12V, the maximum output power is 700W, ripple and noise are ≤150mV, and the efficiency reaches 86%. This module is responsible for converting the high-voltage DC power, after a series of processing steps, into low-voltage DC power suitable for charging the 300mAh battery.

[0073] The AC rectifier and filter circuit 102b consists of an AC input switch S3, an AC input power filter L4, a rectifier bridge A1, and four high-voltage, high-capacity electrolytic capacitors. Its main function is to convert the input 220V AC power into 300V DC power, preparing for the subsequent step-down conversion.

[0074] Preferably, the high-voltage DC input filter circuit 102c includes a common-mode inductor L2, two differential-mode capacitors, and two common-mode capacitors. This circuit can eliminate electromagnetic interference in the AC mains power supply, acting like a "cleaner" to make the input high-voltage DC power purer. It also incorporates surge interference filtering and reverse protection circuits to prevent reverse voltage damage to the equipment.

[0075] Preferably, the high-voltage step-down submodule 102d is based on the power conversion module N7, and includes components such as the digital potentiometer N3, output filter capacitors C14 and C19, and reverse protection diode D8. The power conversion module N7 can directly step down 300V high-voltage DC to 28V or 12V DC. The output voltage can be adjusted by the digital potentiometer N3 and controlled by the CPU module 201.

[0076] The rest of the structure is the same as in Example 1.

[0077] Working principle: When charging the 300mAh battery using 220V AC mains power, the AC input switch S3 is first closed, and the 220V AC current flows into the AC input power filter L4, filtering out electromagnetic interference introduced by the input wires. Then, the current enters the rectifier bridge A1, converting the AC power into a pulsating DC voltage. Next, after being filtered by four high-voltage, high-capacity electrolytic capacitors in parallel, the pulsating DC voltage is converted into a stable 300V DC voltage.

[0078] The 300V DC voltage is fed into the high-voltage DC input filter circuit 102c, where components such as the common-mode inductor L2, differential-mode capacitor, and common-mode capacitor further eliminate interference and ensure voltage purity. The processed high-voltage DC then enters the high-voltage step-down submodule 102d. Under the control of the CPU module 201, the power conversion module N7, based on the parameters set by the digital potentiometer N3, steps down the 300V high voltage to a charging voltage of 28V or 12V.

[0079] When resting at the vehicle's parking location or performing routine maintenance, the vehicle's 220V AC power can be used to charge the battery 300. The AC charging module 102 converts the 220V AC power into 28V or 12V DC power suitable for charging the battery 300, enabling simultaneous charging of multiple batteries 300. This not only simplifies operation but also improves charging efficiency, providing a reliable power supply for the vehicle's normal use. Especially after the battery 300 has naturally discharged and depleted, it can quickly restore its charge, ensuring the vehicle is always in good working condition. Example 3

[0080] Reference Figures 1-20 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a power detection and display unit 500, which can quickly understand the power status of the battery 300 and the working status of the charging device, so as to facilitate timely charging operations or fault diagnosis and ensure the normal use of the vehicle in high-altitude and cold environments.

[0081] Specifically, the power detection and display unit 500 is used to detect and display the power of the battery 300 online, and includes a battery discharge circuit 501, a voltage display circuit 502, and a power display circuit 503 that are electrically connected to each other.

[0082] Furthermore, the battery discharge circuit 501 mainly consists of a discharge control relay, a protection diode, a discharge power resistor, and a relay control drive integrated circuit. This circuit discharges the battery 300 for a short time, detects the voltage drop slope, and qualitatively judges the battery's charge status by combining battery voltage detection. It acts like a "charge tester" and can quickly assess the remaining charge of the battery 300.

[0083] The voltage display circuit 502 consists of three three-digit common-cathode digital tubes N27, N28, and N29, and digital tube driver control chips N26 and N36. N26 drives and controls N28 and N29, while N36 controls the N27 digital tube, achieving accurate display of the battery 300 voltage and allowing users to intuitively understand the voltage status of the battery 300.

[0084] Preferably, the power display circuit 503 is composed of resistors and light-emitting diodes, with each light-emitting diode corresponding to a different status indication, such as charging indication, discharging indication, fault indication, etc. Through different combinations of on and off states, the working status of the charging device can be clearly displayed to the user.

[0085] The rest of the structure is the same as in Example 2.

[0086] Working principle: When it is necessary to detect the battery level of the storage battery 300, the CPU module 201 sends a command to the relay control driver integrated circuit in the discharge circuit of the storage battery 300, driving the discharge control relay to activate and connect the circuit from the storage battery 300 to ground through the discharge power resistor, causing the storage battery 300 to begin discharging for a short period of time. During this process, the discharge power resistor consumes the electrical energy of the storage battery 300, generating current. At the same time, the CPU module 201 controls the voltage detection circuit 203 to detect the discharge voltage of the storage battery 300 in real time.

[0087] After discharging for a period of time (e.g., 10 seconds), the CPU module 201 stops discharging and analyzes and calculates the voltage data before and after discharge to obtain the voltage drop slope. Combined with the currently detected battery voltage value, it is compared with the pre-set discharge curve of the battery 300 to qualitatively determine whether the battery 300's charge level is high, medium, or low.

[0088] Meanwhile, the digital tube driver control chip in the voltage display circuit 502 drives the corresponding digital tubes to display specific voltage values ​​based on the voltage data sent by the CPU module 201. For example, the voltage of the 24V battery 300 is displayed on digital tube N27, the voltage of the 12V1 battery 300 is displayed on digital tube N28, and the voltage of the 12V2 battery 300 is displayed on digital tube N29, allowing the user to intuitively see the voltage status of each battery 300.

[0089] The LEDs in the power display circuit 503 will also illuminate corresponding indicator lights according to the instructions of the CPU module 201. For example, when the 24V battery 300 has a high charge, the corresponding green LED lights up; when the charge is medium, the yellow LED lights up; and when the charge is low, the red LED lights up. In this way, users can quickly understand the charge status of the battery 300 and the working status of the charging device without complicated instruments or professional knowledge, which facilitates timely charging operations or troubleshooting and ensures the normal use of the vehicle in high-altitude and cold environments.

[0090] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
