Description

TECHNICAL FIELD

[0001] The present application relates to the field of water sports equipment, in particular to a battery charging and discharging device for water sports equipment. BACKGROUND

[0002] The existing battery charging and discharging device of water sports equipment generally adopts a single charging socket design, and the main function is to manage the charging or discharging of the device battery individually. These devices generally achieve the charging and discharging process through simple circuit control, with the advantages of low design cost and easy operation. However, with the development of water sports equipment towards higher performance and longer endurance, the limitations of single socket design in efficiency, balance and safety are increasingly apparent, making it difficult to meet the diversified needs of modern water sports equipment.

[0003] In the prior art, the single socket charging device in the use environment of multiple battery packs is prone to cause unbalanced charging of the batteries. Due to the differences in the amount of electricity, internal resistance or aging degree between individual batteries, overcharging of some batteries or undercharging of some batteries often occurs during charging, thereby affecting the overall performance and service life of the battery pack. In addition, most traditional charging devices lack effective multi-battery coordinated charging function, resulting in low energy distribution efficiency, which is not conducive to the stable operation of long-time high-load equipment. Especially in water sports equipment, this problem may directly cause equipment failure or accidents, posing a great safety hazard.

[0004] On the other hand, the safety of battery storage and transportation in the non-use state has not been fully considered in the prior art. Since the batteries of water sports equipment usually have high energy density, if the batteries are stored for a long time without being properly discharged or are affected by the outside world during transportation, there may be a risk of spontaneous combustion or explosion. Most existing charging and discharging devices lack built-in safety discharge function, and this design defect makes it necessary for device users to use professional discharge equipment or spend a lot of time for manual processing when storing and transporting batteries, which is neither convenient nor economical.

[0005] In addition, long-term full-charge storage of batteries is also one of the important factors affecting the service life. Long-term storage of lithium-ion batteries in high-charge state can easily cause irreversible damage to battery materials, thereby shortening the service life of the battery. Studies have shown that the optimal storage capacity of the battery is usually around 80%, which can avoid the material aging problem caused by high-charge state and maintain the stability of battery performance. However, the existing charging and discharging device lacks precise capacity control function in daily use, and users often have difficulty in achieving reasonable storage capacity management, thereby accelerating the aging of the battery and affecting the long-term performance and use economy of the equipment.

[0006] Therefore, it is necessary to develop a battery charging and discharging device with a multi-jack design, which can effectively solve the problem of charging balance of multiple battery groups and improve the safety in non-use state through the built-in discharging function.

[0007] It should be understood that the disclosure of the above background art is only used to assist in understanding the inventive concept and technical solutions of the utility model, and it does not necessarily belong to the prior art of the utility model. In the absence of explicit evidence that the above content has been disclosed before the application date of the utility model, the above background art should not be used to evaluate the novelty and inventiveness of the utility model. Utility model content

[0008] The purpose of the present application is to overcome at least one deficiency in the prior art, provide a battery charging and discharging device for water sports equipment, which can realize cooperative charging between multiple battery groups through multiple jacks, ensure the balance of the power distribution between the batteries, prolong the service life of the equipment battery, and further improve the reliability and efficiency of the equipment operation. At the same time, the built-in discharging function can help users quickly handle the energy release problem before storing or transporting the battery, greatly reducing the safety hazards, thereby providing a more convenient and safer use experience for users of water sports equipment, and having important technical value and market potential.

[0009] To achieve the above-mentioned purpose, the present application discloses a battery charging and discharging device suitable for water sports equipment, which comprises a body with at least two battery charging and discharging positions and a power adapter connected to the body through a detachable electrical connection mode; wherein the body is internally provided with a control panel and a discharging assembly connected to the control panel to realize the charging and discharging control of the charged batteries.

[0010] In the specific structure, each battery charging and discharging position of the body is provided with a group of connection terminals, and each group of connection terminals and the control panel form an independent charging and discharging branch, thereby ensuring the independence and safety of each battery unit.

[0011] The control panel is integrated with a monitoring circuit, which can be connected to each group of connection terminals and at least monitor the voltage of the charged batteries in the battery charging and discharging position in real time. Through the voltage value of the charged batteries, the control panel can accurately judge the power state of each charged battery. When the voltages of different battery charging and discharging positions are different, the control panel can intelligently adjust the charging state of each charging and discharging position according to the detected voltage data to realize the balanced adjustment of the voltages of each charged battery, thereby effectively avoiding the overcharging or undercharging of a certain battery.

[0012] The body is provided with a control switch connected to the control panel, and the user can manually or automatically control the charging or discharging operation of the battery through the switch to provide a convenient use interface.

[0013] To achieve charging, the discharging assembly includes a resistive heater and a heat sink opposite to it. The resistive heater generates heat during discharging, and the heat sink effectively dissipates excess heat to prevent overheating of the device and ensure stable operation.

[0014] In some embodiments, the body is provided with a heat dissipation port corresponding to the heat sink, which is designed as a porous array to increase the air flow area and improve the heat dissipation efficiency.

[0015] In some embodiments, each battery charging and discharging position on the body is provided with a corresponding indicator light, which is designed as a multi-color LED for displaying the battery charging and discharging status. For example, a green indicator light indicates that the battery is fully charged, a red indicator light indicates that the battery is charging, and a yellow indicator light indicates that the battery is low or in an abnormal state.

[0016] The indicator light is connected to the control board and can update the display status in real time according to the battery voltage, current and temperature data collected by the monitoring circuit. Preferably, the indicator light can also be configured with a flashing mode to prompt the user that the battery is about to be fully charged, charging abnormally or needs maintenance. In addition, the brightness of the indicator light can be adjusted to meet the visibility requirements in different lighting environments.

[0017] In some embodiments, the connection terminal set includes a positive terminal and a negative terminal, each of which is made of a corrosion-resistant and highly conductive material, such as gold-plated or silver-plated copper alloy, to ensure long-term stability and low contact resistance. The connection terminal set further includes an elastic contact sheet to ensure close contact with the battery electrode and prevent poor contact caused by vibration or impact. In addition, preferably, the connection terminal set is configured with a reverse connection protection circuit to prevent damage to the device or battery when the battery polarity is reversed.

[0018] In some embodiments, the monitoring circuit includes a voltage sampling module, a current sampling module and a temperature sampling module for real-time collection of voltage, current and temperature data of the battery being charged. The monitoring circuit further includes an analog-to-digital converter for converting analog signals to digital signals and transmitting them to the control board. Preferably, the monitoring circuit also integrates overvoltage, undervoltage, overcurrent and overtemperature protection functions, which automatically cut off the charging and discharging circuit when abnormal data is detected to ensure the safety of the battery and the device.

[0019] In some embodiments, the discharge assembly includes at least one power resistor and a MOSFET switch connected in series, for controlling the magnitude and on-off of the discharge current. The power resistor is made of high-heat-resistant materials such as ceramics or metal alloys to ensure stability during high-power discharge. The discharge assembly further includes a current feedback circuit for real-time monitoring of the discharge current and feeding back data to the control board to achieve precise discharge control. In addition, the discharge assembly can be configured with multiple discharge modes, automatically adjusting the discharge rate according to the battery state to prolong the battery life.

[0020] In some embodiments, the control board includes a microcontroller unit (MCU) and a storage unit connected thereto, which is used to store charging and discharging parameters, fault logs, and user settings. The control board further integrates a PWM control module for adjusting the charging current and voltage to achieve constant current charging, constant voltage charging, and multi-stage charging modes. The control board can also be configured with a communication interface such as UART, I2C, or SPI for data interaction with external devices or host computers, enabling remote monitoring and control.

[0021] In some embodiments, the heat sink includes aluminum or copper heat dissipation fins that are tightly connected to the resistance heater through thermal conductive glue or welding to maximize heat conduction efficiency. The heat sink further includes a fan module connected to the control board, which can automatically adjust the fan speed according to the feedback data of the temperature sensor to achieve dynamic heat dissipation control. In some embodiments, the surface of the heat sink can be coated with an anti-oxidation coating to enhance its durability in humid environments. In addition, the heat sink can be designed as a detachable structure for easy cleaning and maintenance by users.

[0039] See attached document Figs. 1 to 4 This embodiment provides a battery charging and discharging device suitable for water sports equipment. This device aims to meet the balanced management needs of charging and discharging multiple battery packs, providing users with an efficient, safe, and reliable battery charging and discharging solution. Through independent charging and discharging branches, monitoring circuits, discharging components, and indicator lights, the device achieves intelligent control and dynamic feedback of battery status, thereby effectively improving the overall performance of the battery pack, extending battery life, and reducing the risks of equipment operation under high loads and special environments.

[0040] In terms of specific structure, the main body 1 is the main structure of the device, and it has at least two battery charging / discharging positions 2 inside. Each battery charging / discharging position 2 is equipped with a connection terminal group, which consists of several connection terminals arranged at intervals, for electrical connection with the battery 4 being charged. Through the circuit connection between these connection terminals and the control board 5, each battery charging / discharging position 2 forms an independent charging / discharging branch, so as to ensure that each battery cell does not interfere with each other during operation, thereby effectively avoiding the shortened service life and performance degradation caused by uneven battery power distribution.

[0041] In some embodiments, the connection terminal group further comprises a reverse connection protection circuit to prevent damage to the device or the battery when the battery polarity is reversed.

[0042] The power adapter 3 is detachably connected to the body 1 to provide the required power for the battery. In a typical design, the power adapter 3 includes an input end, a conversion circuit (such as a rectifier circuit, a filter circuit, a voltage conversion module, and a voltage stabilizing module), and an output end. The input end can be connected to a conventional power supply, and the output end provides a stable voltage and current to meet the specific needs of the battery 4 being charged. In this embodiment, the internal circuit design, component selection, heat dissipation method, and related electrical safety protection measures (such as overvoltage protection, overcurrent protection, overtemperature protection, and electromagnetic compatibility design) of the power adapter 3 are known to those skilled in the art, and their specific implementation methods do not need to be described in detail here. Based on ordinary technical knowledge, those skilled in the art can reasonably design the input and output parameters and internal structure of the power adapter 3 according to the actual application requirements and the characteristics of the battery. Therefore, the detailed disclosure of this part will not affect the complete implementation of this embodiment.

[0043] The control board 5 is an important part of the device, which integrates monitoring circuits and related electrical elements for real-time detection of the voltage state of the battery in each charging and discharging position 2. The control board 5 can intelligently adjust the charging current and voltage of each charging and discharging position based on the detected battery voltage information. When the voltage of any battery is too high, the control board 5 reduces the charging current or temporarily interrupts the charging to prevent overcharging; when the battery voltage is too low, it increases the charging current or extends the charging time to make up for the lack of power. Through this real-time balancing and adjustment, the control board 5 can ensure more balanced distribution of power among the batteries, significantly reducing the aging rate of the batteries and extending the overall service life of the battery pack. In some embodiments, the control board 5 also integrates a temperature sensor for real-time monitoring of the internal temperature of the device and automatically adjusting the charging and discharging rate or starting the radiator 7 (fan) for active cooling according to temperature changes.

[0044] In terms of control operation, the control board 5 is connected to the control switch exposed on the body 1, allowing users to choose automatic or manual control mode. For example, an automatic mode or a manual mode can be set, in which the control board 5 automatically adjusts the charging and discharging process according to the battery voltage changes without human intervention; in manual mode, users can freely switch the charging and discharging state according to their actual needs. This flexible control strategy improves the convenience and applicability of the device. In some embodiments, the control board 5 can also communicate with external devices (such as smartphones or tablets) through Bluetooth or Wi-Fi modules to achieve remote monitoring and control.

[0045] The embodiment also provides a discharging assembly to meet the requirement of energy release before storage or transportation of the battery. The discharging assembly includes a resistance heater 6 and a heat sink 7, wherein the heat sink 7 is a fan structure in the embodiment. During the discharging process, the resistance heater 6 converts electrical energy into heat energy, and the heat sink 7 (fan) is used to quickly discharge excess heat to maintain the system within a safe temperature range, thereby preventing safety risks and performance degradation caused by overheating. To further improve the heat dissipation effect, the body 1 is provided with a heat dissipation port corresponding to the heat sink 7, which effectively enhances the cooling performance by strengthening air circulation, ensuring stable operation of the device under high load operating conditions. In some embodiments, the heat sink 7 can also use liquid cooling to further improve the heat dissipation efficiency.

[0046] To facilitate users to know the battery status in real time, the embodiment configures an indicator light on the battery charging and discharging position 2. In actual work, the user can be shown the current battery working condition through the color and state change of the indicator light, for example: green represents normal charging or working state, yellow represents charging or discharging process, and red represents abnormal state or low power. Through the dynamic display of the indicator light, the user can intuitively master the running condition of each battery charging and discharging position, so as to make corresponding operation adjustment in time, reducing the possibility of safety hazards and misoperation. In some embodiments, the indicator light can also be configured with brightness adjustment function to adapt to the visibility requirements in different lighting environments.

[0047] In summary, the embodiment realizes efficient charging and discharging management and safety protection of multiple battery packs through the independent branch design of multiple battery charging and discharging positions, intelligent voltage balance regulation, discharging assembly and heat dissipation port configuration, indicator light state display, and reasonable selection of power adapter 3 and detachable electrical connection mode.

[0048] It should be emphasized that the conventional technical means and well-known structures known to those skilled in the art, such as the internal circuit design of the power adapter 3, the circuit principle of the control board 5 and related safety protection measures, are not described in detail in the embodiment, and these contents will not affect the complete implementation of the embodiment even if they are not disclosed. The embodiment finally provides a safer, more efficient and easier battery management scheme for users, which brings significant technical progress and economic value to water sports equipment and other occasions with strict requirements for battery management.

[0049] Although the exemplary embodiments of the present disclosure have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the protection scope of the present disclosure defined by the claims.
