Description

Technical Field

[0001] This invention relates to the field of fast-charging battery technology, and more particularly to a fast-charging battery and its module. Background Technology

[0002] Fast-charging batteries are energy storage devices with high-rate charging capabilities. By optimizing the cell material system and battery management system, they can replenish a large amount of electrical energy in a short time. They are widely used in smartphones, laptops, electric vehicles, portable energy storage devices, and other fields. Their core value lies in significantly shortening charging time, improving the ease of use and battery life of devices, and have become an important support for the development of the new energy and electronic information industries.

[0003] In existing technologies, the typical structure of a fast-charging battery module mainly includes a battery cell, a casing, an electrode lead-out structure, and a battery management unit. The battery cell, mostly using a lithium-ion system and manufactured through winding or stacking processes, is the core carrier for energy storage. The casing, usually made of metal or rigid plastic, is used to fix the battery cell and provide basic physical protection. The electrode lead-out structure enables the electrical connection between the battery cell and external charging equipment. The battery management unit collects parameters such as the battery cell's voltage and current to achieve safe monitoring and power regulation during the charging process.

[0004] However, in frigid regions such as northern China, winter temperatures can drop to -20°C or even lower, far below the optimal operating temperature range for fast-charging batteries. In such extreme low-temperature environments, the viscosity of the electrolyte inside the battery cell increases dramatically, and ion migration is almost completely blocked. This not only leads to a complete loss of fast-charging acceptance but also prevents normal charging from even starting. Long-term charging in this environment will accelerate the degradation of battery cell capacity and shorten its lifespan.

[0005] Accordingly, this application proposes a fast-charging battery and its module. Summary of the Invention

The drop protection component is used to prevent the battery from being damaged due to the battery box being dropped. The preheating and heat dissipation component is used to preheat the battery to ensure fast charging performance at low temperatures; the preheating and heat dissipation component is also used to dissipate heat from the battery in hot weather. The alarm component is used to issue an alarm when the battery cell assembly swells.

[0014] Preferably, the insulating box contains two charging cables, one end of which passes through the insulating box and the battery box and extends outward. The battery box has protective plates on both sides, and the protective plates have several heat dissipation holes located at the fan.

[0015] Preferably, a cover is fixedly installed on the top of the battery box by screws, and the cover is provided with two handles.

[0016] A fast-charging battery module includes the following modules: Integrated structural modules Integrating all mechanical structural components, through the assembly and linkage of components, it realizes the basic functions of cell support, drop protection, airflow conduction and mechanical linkage alarm, and provides stable physical support and mechanical action execution carrier for the other four modules; Fast charging control module Built-in fast charging protocol chip and current and voltage regulation chip. The fast charging protocol chip is compatible with mainstream fast charging protocols, automatically identifies the fast charging type of external charging devices and completes protocol matching. The current and voltage regulation chip dynamically adjusts the charging current and voltage according to the protocol requirements, and adopts a three-stage charging method of constant current, constant voltage and trickle charging, which improves the charging speed while avoiding damage to the battery cell due to overcurrent and overvoltage. Intelligent temperature control chip module It integrates a temperature sensing chip and a temperature control algorithm chip. The temperature sensing chip collects the internal ambient temperature data of the module in real time, and the temperature control algorithm chip has a built-in temperature threshold model. It analyzes and processes the temperature data through the algorithm. When the temperature is lower than the fast charging suitable threshold, it outputs a preheating start signal. When the temperature is higher than the safe working threshold, it outputs a heat dissipation start signal, and independently completes temperature monitoring and signal output. Battery cell health monitoring chip module The cell characteristic monitoring chip detects the core parameters of the cell in real time, such as voltage, internal resistance, and cycle count. The data processing chip analyzes the collected parameters and establishes a cell health status assessment model. When a potential health hazard such as abnormal increase in cell internal resistance or excessively rapid voltage decay is detected, a cell abnormality warning signal is output, thereby realizing the monitoring and assessment of the cell health status. Security protection chip module It includes overcurrent protection chip, overvoltage protection chip, overtemperature protection chip and short circuit protection chip. Each protection chip monitors the current, voltage, temperature and circuit continuity of the charging circuit in real time. When any parameter exceeds the safety threshold, the corresponding chip independently triggers the protection mechanism to quickly cut off the charging circuit and prevent safety accidents caused by overcurrent, overvoltage, overtemperature or short circuit of the battery cell.

[0017] The present invention has the following beneficial effects: 1. Through the anti-fall components, the electric telescopic rod drives the sliding rod and air plug to reciprocate inside the air cylinder. The air cylinder draws in air through the air inlet pipe and then delivers the air to the inflation bladder through the inflation pipe. At the same time, the one-way valve at the air cylinder can prevent the air inside the inflation bladder from flowing back. After the inflation bladder reaches the inflated state, it wraps and protects the battery box. When the battery box is hit or dropped, the inflation bladder can absorb the external impact force through its own deformation, preventing the battery box from being directly damaged by contact with the outside world.

[0018] Second, through the preheating and heat dissipation components, when the motor drives the guide tube to rotate and the air hole rotates to the through hole, the heating wire in the airbag generates heat. Under the action of the anti-drop component inflation, the air in the battery box is drawn into the airbag. The air in the airbag comes into full contact with the heat generated by the heating wire and heats up. The heated air then flows back into the battery box through the air hole of the guide tube and the through hole of the strip, forming an air circulation heating circuit to continuously heat the battery and prevent the local temperature of the battery cell group from being too low, which would affect the fast charging performance. At the same time, the one-way valve can prevent the air in the airbag from flowing back into the air cylinder or battery box through the air inlet pipe or inflation pipe, so that the airbag can always be kept in an inflated state, realizing the simultaneous operation of the preheating function and the anti-drop function.

[0019] Third, through the preheating heat dissipation components, when the fan is working, it draws hot air from the battery box. The motor drives the guide tube to rotate and adjusts the orientation of the air vents so that they are laterally biased towards the direction of hot air loss. With the continuous inflation of the anti-drop components, the air vents continuously generate airflow. The auxiliary airflow formed works in conjunction with the main airflow generated by the fan to accelerate the flow speed and discharge efficiency of hot air in the battery box, improve the overall heat dissipation efficiency, and prevent the battery cells from experiencing a decrease in fast charging performance or damage to the internal structure due to high temperature.

[0020] IV. Through the alarm component, when the battery cell assembly expands, the battery cell assembly pushes the insulation box to deform. The deformed insulation box bulges and pushes the slot block to slide on the battery box. The sliding of the slot block changes the relative position between the round hole and the light sensor. After the light sensor detects the position change, it sends a signal to the control system. The control system causes the motor to drive the air hole on the guide tube to rotate to the block's closed position, so that the airflow cannot be discharged from the air hole and can only be discharged from the buzzer. When the air enters the buzzer through the round hole, the buzzer connects to the outside, forming an airflow discharge channel. With the continuous inflation of the anti-drop component, the airflow is continuously discharged through the buzzer and emits a sound, so that the staff can promptly notice the abnormal expansion of the battery cell assembly and take corresponding measures to prevent the battery cell assembly from being damaged further.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Example 1: Reference Figure 1 , Figure 2 , Figure 5 and Figure 7 A fast-charging battery includes a battery box 1, an insulating box 27, a battery cell assembly 28, a drop protection component, a preheating and heat dissipation component, and several alarm components. Two charging cables 6 are installed inside the insulating box 27. One end of the charging cable 6 passes through the insulating box 27 and the battery box 1 and extends outward to realize the power transmission between the battery cell assembly 28 and the outside. A box cover 13 is fixedly installed on the top of the battery box 1 by screws to seal the internal space of the battery box 1. Two handles 30 are provided on the box cover 13 to facilitate the movement of the battery box 1. The battery cell assembly 28 is fixedly installed inside the insulating box 27 to provide power. The insulating box 27 is set inside the battery box 1 to insulate and protect the battery cell assembly 28. Supports 14 are fixedly connected to both sides of the insulating box 27 to support and fix the electric telescopic rod 9. The electric telescopic rod 9 is fixedly installed on the support 14 to provide power for the anti-fall component. Mounting frames 26 are set around the battery box 1 to fix the inflatable bag 2. The drop protection component is used to prevent battery damage caused by the battery box 1 being dropped. The preheating and heat dissipation component is used to preheat the battery to ensure fast charging performance at low temperatures; the preheating and heat dissipation component is used to dissipate heat from the battery when it is hot. The alarm component is used to trigger an alarm when cell group 28 bulges.

[0025] The anti-fall component includes four connecting pipes 5, four airbags 2, four bend pipes 3, two air cylinders 7, and two inflation pipes 25. The connecting pipes 5 are connected to the airbags 2 to enable airflow communication between adjacent airbags 2. The airbags 2 are fixedly installed in the mounting frame 26 to provide anti-fall protection for the battery box 1 through inflation. The four bend pipes 3 are interconnected through the four airbags 2 to enable overall airflow communication between the four airbags 2. The air cylinders 7 are fixedly installed on the battery box 1 to provide a cavity for inflating the airbags 2. One end of the inflation pipe 25 is connected to the air cylinder 7, and the other end is connected to the airbag 2 to deliver air from the air cylinder 7 to the airbag 2.

[0026] The anti-fall component also includes two air inlet pipes 8, two slide rods 23, and two air plugs 24. One end of the air inlet pipe 8 is connected to the battery box 1, and the other end is connected to the air cylinder 7. It is used to introduce air from the battery box 1 into the air cylinder 7. The slide rod 23 is slidably connected to the air cylinder 7 and is used to drive the air plug 24 to move. The air plug 24 is slidably connected inside the air cylinder 7 and is used to move inside the air cylinder 7 to realize the intake and exhaust of air. The slide rod 23 is fixedly connected to the air plug 24 and is used to transmit power. The slide rod 23 is fixedly connected to the output end of the electric telescopic rod 9 and is used to receive the power of the electric telescopic rod 9. One-way valves are provided at the connection points of the air inlet pipe 8 and the inflation pipe 25 with the air cylinder 7 to prevent air backflow and ensure the smooth inflation process.

[0027] In this embodiment, the electric telescopic rod 9 drives the slide rod 23 and the air plug 24 to reciprocate inside the air cylinder 7. The air cylinder 7 draws in air through the air inlet pipe 8 and then delivers the air to the airbag 2 through the inflation pipe 25. At the same time, the one-way valve at the air cylinder 7 can prevent the air inside the airbag 2 from flowing back. After the airbag 2 reaches the inflated state, it can wrap and protect the battery box 1. When the battery box 1 is hit or falls, the airbag 2 can absorb the external impact force through its own deformation, preventing the battery box 1 from being directly damaged by contact with the outside world.

[0028] Example 2: Unlike Example 1, referring to Figure 1 , Figure 2 and Figure 4 This embodiment also has the following further features: The preheating and heat dissipation assembly includes several guide pipes 10, four fans 11, several air holes 12, several through holes 22, and several strips 16. The four fans 11 are installed in pairs on both sides of the battery box 1 to realize air exchange between the inside and outside of the battery box 1 and to dissipate heat inside the battery box 1. The guide pipes 10 are connected to the airbag 2. The air holes 12 are set on the guide pipes 10 to realize air exchange between the inside and outside of the guide pipes 10. The several strips 16 are fixedly installed on the outside of the battery box 1.

[0029] A through hole 22 is provided on the strip 16 and is connected to the battery box 1 to enable airflow communication between the strip 16 and the battery box 1. The guide pipe 10 is provided on one side of the fan 11, and the air hole 12 is offset to the side of the fan 11. The air hole 12 and the through hole 22 are positioned to enable precise airflow connection between the guide pipe 10 and the battery box 1. A motor 15 is fixedly installed on the strip 16 to provide power for the rotation of the guide pipe 10. The drive shaft of the motor 15 is fixedly connected to the guide pipe 10 to transmit the power of the motor 15 to drive the guide pipe 10 to rotate.

[0030] The airbag 2 is equipped with a heating wire to generate heat for battery preheating. The battery box 1 is provided with protective plates 4 on both sides to protect the fan 11 and the side structure of the battery box 1. The protective plates 4 are provided with several heat dissipation holes 29, which are located at the fan 11 to allow airflow from the fan 11.

[0031] In this embodiment, when the motor 15 drives the guide pipe 10 to rotate, causing the air hole 12 to rotate to the through hole 22, the heating wire inside the airbag 2 generates heat. Under the inflation of the anti-drop component, air from the battery box 1 is drawn into the airbag 2. The air inside the airbag 2 comes into full contact with the heat generated by the heating wire and heats up. The heated air then flows back into the battery box 1 through the air hole 12 of the guide pipe 10 and the through hole 22 of the strip 16, forming an air circulation heating circuit to continuously heat the battery and prevent the local temperature of the cell assembly 28 from being too low, which would affect the fast charging performance. At the same time, the one-way valve can prevent air in the airbag 2 from passing through the air inlet pipe 8 or the inflation pipe 2. 5. The air flows back to the air cylinder 7 or the battery box 1, which can keep the airbag 2 in an inflated state at all times, so as to realize the simultaneous operation of the preheating function and the anti-drop function. When the fan 11 is working, it draws away the hot air from the battery box 1. The motor 15 drives the guide tube 10 to rotate and adjusts the orientation of the air hole 12 so that its side is biased towards the direction of the hot air flow. Under the continuous inflation of the anti-drop component, the air hole 12 continuously generates airflow. The auxiliary airflow formed and the main suction airflow generated by the fan 11 work together to accelerate the flow speed and discharge efficiency of the hot air in the battery box 1, improve the overall heat dissipation efficiency, and prevent the battery cell group 28 from degrading its fast charging performance or being damaged internally due to high temperature.

[0032] Example 3: Reference Figure 1 , Figure 3 and Figure 6 Compared to Embodiment 1 and Embodiment 2, in this embodiment: The alarm assembly includes a mounting block 21, a buzzer 19, a light sensor 20, a slot 17, and a round hole 18. The mounting block 21 is fixedly connected to the outside of the battery box 1 and is used to fix the light sensor 20. The light sensor 20 is fixedly mounted on the mounting block 21 and is used to detect the position change of the round hole 18 to trigger a signal. The buzzer 19 is connected to the bend tube 3 and is used to emit an audible alarm through the airflow.

[0033] The slot block 17 is slidably connected to the battery box 1 and is used to slide on the battery box 1 to transmit the deformation displacement of the insulating box 27. The slot block 17 is slidably connected to the buzzer 19 and is used to control the airflow channel of the buzzer 19 by sliding. The circular hole 18 is set on the slot block 17 and is used to cooperate with the optical sensor 20 to realize position detection. One end of the slot block 17 is fixedly connected to the insulating box 27 and is used to receive the deformation thrust of the insulating box 27 caused by the expansion of the battery cell assembly 28. The circular hole 18 corresponds to the position of the optical sensor 20 and is used to ensure that the optical sensor 20 can accurately detect the position change of the circular hole 18.

[0034] In this embodiment, when the battery cell assembly 28 expands, it pushes the insulating box 27 to deform. The deformation of the insulating box 27 causes the groove block 17 to slide on the battery box 1. The sliding of the groove block 17 changes the relative position between the circular hole 18 and the light sensor 20. After the light sensor 20 detects the position change, it sends a signal to the control system. The control system causes the motor 15 to drive the air hole 12 on the guide tube 10 to rotate to the closed position of the strip block 16, so that the airflow cannot be discharged from the air hole 12 and can only be discharged from the buzzer 19. When the circular hole 18 enters the buzzer 19, the buzzer 19 is connected to the outside, forming an airflow discharge channel. Under the continuous inflation of the anti-drop component, the airflow is continuously discharged through the buzzer 19 and emits a sound, so that the staff can promptly notice the abnormal expansion of the battery cell assembly 28 and take corresponding measures to prevent the damage to the battery cell assembly 28 from further expanding.

Intelligent temperature control chip module It integrates a temperature sensing chip and a temperature control algorithm chip. The temperature sensing chip collects the internal ambient temperature data of the module in real time, and the temperature control algorithm chip has a built-in temperature threshold model. It analyzes and processes the temperature data through the algorithm. When the temperature is lower than the fast charging suitable threshold, it outputs a preheating start signal. When the temperature is higher than the safe working threshold, it outputs a heat dissipation start signal, and independently completes temperature monitoring and signal output. Battery cell health monitoring chip module The cell characteristic monitoring chip detects the core parameters of the cell in real time, such as voltage, internal resistance, and cycle count. The data processing chip analyzes the collected parameters and establishes a cell health status assessment model. When a potential health hazard such as abnormal increase in cell internal resistance or excessively rapid voltage decay is detected, a cell abnormality warning signal is output, thereby realizing the monitoring and assessment of the cell health status.

When the temperature is higher than the safe working threshold, it outputs a heat dissipation start signal, and independently completes temperature monitoring and signal output. Battery cell health monitoring chip module The cell characteristic monitoring chip detects the core parameters of the cell in real time, such as voltage, internal resistance, and cycle count. The data processing chip analyzes the collected parameters and establishes a cell health status assessment model. When a potential health hazard such as abnormal increase in cell internal resistance or excessively rapid voltage decay is detected, a cell abnormality warning signal is output, thereby realizing the monitoring and assessment of the cell health status. Security protection chip module It includes overcurrent protection chip, overvoltage protection chip, overtemperature protection chip and short circuit protection chip. Each protection chip monitors the current, voltage, temperature and circuit continuity of the charging circuit in real time. When any parameter exceeds the safety threshold, the corresponding chip independently triggers the protection mechanism to quickly cut off the charging circuit and prevent safety accidents caused by overcurrent, overvoltage, overtemperature or short circuit of the battery cell.
