Description

Technical Field

[0001] The utility model relates to the technical field of battery starting, in particular to a starting battery with a wake-up function. Background Art

[0002] Finished battery products (i.e., battery modules in the present invention) refer to battery products that have been manufactured through a series of production process flows. They can be directly used in various electronic devices. Usually, finished battery products include battery packs and battery management systems. Among them, a battery pack refers to an assembly in which multiple battery cells are combined in series and parallel, and packaged, encapsulated, and assembled according to the shape required by the customer; a battery management system (BMS) can manage, control, and use the battery, improve the utilization rate of the battery, and prevent the battery from being overcharged and over-discharged. The BMS usually activates over-discharge protection when the battery cell is almost fully discharged, and the battery pack no longer outputs power to the outside to prevent the battery cell from being damaged by over-discharge. Usually, a battery pack with discharge protection can only be restored to normal operation by charging.

[0003] Starting batteries are used to start gasoline and diesel internal combustion engines in cars, motorcycles, and general-purpose vehicles. When a car, motorcycle, or general-purpose vehicle is not in use, some onboard electronic equipment continues to operate, requiring the starting battery to provide a low current. Prolonged inactivity can cause the starting battery to become depleted. When the battery management system activates over-discharge protection, it interrupts power flow, rendering the vehicle unable to start again and forcing the user to seek a jump-start.

[0004] To address this issue, batteries with sleep-wakeup functions are available on the market. These functions automatically enter a sleep state when the battery is depleted to a certain level or has not been used for a period of time, suspending power. To start the vehicle, the user must activate the battery's built-in button to restore power and start the vehicle. However, this solution is difficult to implement, as the starting battery is typically installed inside the vehicle or device, particularly on motorcycles, making direct access difficult and inconvenient.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] Example 1:

[0028] The present invention provides a starting battery with a wake-up function, comprising a battery management module and a grounding wake-up wire, wherein the battery management module comprises a battery pack, a battery management system and a low-battery switch. The controlled path of the low-battery protection switch is connected between the negative electrode of the battery pack and a frame, and the frame is made of an electrically conductive material such as conductive metal, conductive fiber, conductive plastic, etc. The frame is connected to the first end of the mechanical electrical system, and the second end of the mechanical electrical system is connected to the positive terminal of the battery module; at the same time, the fixed end of the grounding wake-up wire is connected to the wake-up end of the battery management system, and the wake-up output end of the battery management system is connected to the control end of the low-battery protection switch, that is, the battery pack and the battery management system establish a communication connection, and the battery management system and the low-battery protection switch exchange information through data signals.

[0029] At the same time, according to existing technologies, when the battery management system detects that the battery pack power has dropped to a certain level and persisted for a certain period of time, that is, the battery power has been depleted to a certain level or the battery has not been used for a period of time, the battery automatically enters a dormant state and the low-power protection switch is disconnected. At this point, the rack and the positive terminal of the battery module are at the same potential.

[0030] Since the free end of the grounding wake-up wire can extend to any position on the rack or extend inside or outside the rack, when the free end of the grounding wake-up wire touches and connects with the conductive rack, the grounding wake-up wire transmits a wake-up signal to the wake-up end of the battery management system. The battery management system controls the low-power protection switch to close, the battery starts working, and the battery pack starts to output voltage.

[0031] The working principle of battery self-starting: The low-battery protection switch is in the off state, and the battery management system is in the dormant state. Because the rack and the mechanical and electrical system are connected and short-circuited, the mechanical and electrical system is equivalent to a large resistor. Therefore, the positive terminal of the rack and the battery module are at the same potential. When the battery needs to be self-started, the free end of the grounding wake-up wire is connected to the conductive rack. Because the fixed end of the grounding wire is connected to the wake-up terminal of the battery management system, the battery management system receives the voltage signal from the positive terminal of the battery module. The battery management system is triggered to wake up by this voltage signal and sends a control signal to the low-battery protection switch, controlling the low-battery switch to close and establish the conductive state, and the battery pack resumes outputting voltage.

[0032] In some embodiments, the frame and the mechanical and electrical system have a one-to-one correspondence. When the frame is a robot frame, the mechanical and electrical system is the robot electrical system; when the frame is a vehicle frame, the mechanical and electrical system is the vehicle electrical system. The connection method of the above one-to-one corresponding frame, mechanical and electrical system and battery pack is the same as that in Example 1, and the battery self-starting principle is also the same.

[0033] In some embodiments, the free end of the grounding wake-up wire can extend outside the rack, that is, extend to any position on the rack, inside the rack, or outside the rack. A position for storing the free end of the grounding wake-up wire can also be set inside or outside the rack, such as a storage box that comes with the rack.

[0034] Example 2:

[0035] like Figure 1 As shown, in this embodiment, the frame adopts the vehicle frame, and the mechanical system adopts the vehicle electrical system. The connection method between the battery pack and the vehicle frame and the vehicle electrical system is the same as that in Example 1, and the battery self-starting principle is also the same. After the battery self-starts, and with the cooperation of the vehicle electrical system, the car starts to start.

[0036] In this embodiment, the starting battery also includes a battery housing, and a grounding wake-up wire interface is provided on the battery housing. The fixed end of the grounding wake-up wire is connected to the grounding wake-up wire interface, and the free end of the grounding wake-up wire can extend outside the vehicle frame.

[0037] In this embodiment, the free end of the ground wake-up wire can extend to any position on the vehicle frame, inside the vehicle frame, or outside the vehicle frame.

[0038] In some embodiments, the free end of the grounding wake-up wire is passed through the interior of the vehicle frame and placed in the glove box or the trunk.

[0039] In some embodiments, the free end of the grounding wake-up wire is stored in the vehicle. For example, the user sticks a storage box on the vehicle, and the free end of the grounding wake-up wire is stored in the stuck storage box.

[0040] Example 3:

[0041] Based on Example 2, in this embodiment, a detachable insulating sheath is provided at the free end of the grounding wake-up wire. If the insulating sheath is snap-connected with the grounding wake-up wire, when the grounding wake-up wire needs to be contacted with the vehicle frame or the machine frame, the insulating sheath can be removed. When not in use, the insulating sheath can be put on the free end of the grounding wake-up wire.

[0042] In some embodiments, the insulating sleeve may include a sleeve top and a sleeve edge, the sleeve edge and the grounding wake-up wire are integrally formed, and the sleeve top and the sleeve edge are snap-connected, such as providing a mutually engaging snap-connecting structure; when the sleeve edge is removed, the free end of the grounding wake-up wire in the sleeve top is exposed from the opening at the sleeve top.

[0043] It should be noted that in order to achieve the insulation effect and reduce production costs, it can be considered to use cross-linked polyethylene material for the insulating sheath.

[0044] Example 4:

[0045] On the basis of the second embodiment, in this embodiment, a grounding wake-up switch button is provided on the vehicle frame, one end of the grounding wake-up switch button is electrically connected to the free end of the grounding wake-up wire, and the other end of the grounding wake-up switch is connected to the vehicle frame.

[0046] When the battery has entered the dormant state, the low-power protection switch is in the disconnected state; when the user presses the ground wake-up button, the frame touches and connects with the free end of the ground wake-up wire. At this time, the ground wake-up wire transmits a wake-up signal to the wake-up end of the battery management system. The battery management system controls the low-power protection switch to close, the battery starts working, and the battery pack starts to output voltage.

[0047] In some embodiments, a grounding wake-up button similar to that in this embodiment may be provided on the robot frame, and the battery self-starting implementation principle thereof is the same as that in this embodiment.

[0048] Embodiment 5:

[0049] In this embodiment, the frame also adopts the vehicle frame, and the mechanical system adopts the vehicle electrical system. The connection method between the battery pack and the frame and the vehicle electrical system is the same as that in the first embodiment, and the battery self-starting principle is also the same.

[0050] In this embodiment, the grounding wake-up wire interface is a metal connecting element, which can be a plug-in connector or a screw-on connector.

[0051] When the metal connecting element is a plug connector, the plug connector can be a metal plug that fits between a metal socket and a metal socket; the rotary connector can be a metal connector body that fits between a metal rotary joint and a metal rotary joint. In a specific embodiment, the grounding wake-up wire interface is a metal socket, and the grounding wake-up wire fixed end is fixedly connected to the metal plug, such as by inserting the grounding wake-up wire fixed end into a socket inside the plug and then securing it with a screw or a clamp; or by directly pressing the grounding wake-up wire fixed end onto the terminal of the plug and applying pressure using a crimping tool to ensure a tight connection between the grounding wake-up wire fixed end and the plug.

[0052] When the metal connecting element is a rotating part, the rotating part can be a metal rotary joint and a metal joint body that cooperates with the metal rotary joint. In a specific embodiment, the grounding wake-up wire interface is a metal rotary joint, and the fixed end of the grounding wake-up wire is fixedly connected to the metal joint body, such as by welding the fixed end of the grounding wake-up wire to the metal joint body, or by crimping the fixed end of the grounding wake-up wire to a metal portion of the metal joint body using a specialized crimping tool.

[0053] In some embodiments, the metal connecting elements can also be metal nuts and metal screws. When the grounding wake-up wire interface is a metal nut, such as an M2 metal nut, a hexagonal nut, a square nut, a butterfly nut and other metal nuts, the fixed end of the grounding wake-up wire is fixed to the metal nut by a screw, and the free end of the grounding wake-up wire extends out of the frame or vehicle frame. The structure is simple and easy to implement.

[0054] In some embodiments, the grounding wake-up interface may also be an M2 metal nut embedded in the battery housing, wherein the fixed end of the grounding wake-up wire is fixed to the M2 metal nut on the battery housing through an M2 metal screw.

[0055] In some other embodiments, the rack may also be a robot or other intelligent device that can use a self-starting battery.

[0056] Example 6:

[0057] In this application, if Figure 2As shown in the circuit diagram of the battery management system for starting the battery, the battery management system consists of U1 and U2, where U1 is the AFE, or analog front end, which is responsible for analog signals such as battery voltage, current, and temperature, and converts them into digital signals for U2 to process. It also has functions such as signal conditioning, isolation, and protection. These functions enable U1 to have higher performance and lower power consumption in the battery management system; U2 is the MCU, or microcontroller, which is the core control unit of the battery management system and is responsible for the control and management of the entire system; U2 receives data from U1 and other sensors, and performs corresponding processing according to preset algorithms and logic to achieve precise control and management of the battery status. It has functions such as data processing and decision-making, communication and interaction, and the implementation of the above functions are all existing technologies.

[0058] exist Figure 2 In the battery management system, U2 (MCU) calculates the remaining battery power by detecting the battery voltage obtained by PI N5 pin RA2. When the power is lower than the set threshold, the PI N2 pin CTLD of U1 (AFE) is controlled to be low through the PI N1 pin RA6 of U2 (MCU). At this time, the PI N6 pin DSG (Discharge Switch Gate) of U1 (AFE) will force the output to be low, thereby pulling down the gate voltage of Q6. Q6 is a MOS tube. At this time, the MOS tube is in the disconnected state, the battery stops outputting, and enters the sleep state.

[0059] When the user touches the free end of the ground to the frame or vehicle frame, the PIN11 pin RB1 of U2 (MCU) receives a rising edge signal, and U2 (MCU) is awakened. At the same time, U2 (MCU) restores the high-level output of the PIN1 pin RA6, causing the PIN6 pin DSG of U1 (AFE) to output a high level. Since Q6 is a MOS tube, at this time, the MOS tube is in the on state again, and the battery resumes normal output.

[0060] The internal wake-up circuit of the battery management system described above is only one implementation method for the battery management system to start up from sleep mode. Other circuits in the prior art that can realize battery self-wake-up can be applied to this embodiment.

[0061] Embodiment seven:

[0062] In this application, the low-power protection switch adopts a MOS tube, or a relay, or a contactor. When the low-power protection switch is in the off state, the battery management system is in the dormant state.

[0063] When using MOS tubes, the battery management system is triggered and awakened by the voltage signal, and sends a control signal to the low-power protection switch to control the closing of the low-power switch and form a conductive state, so that the battery pack outputs voltage again.

[0064] When a relay is used, the control coil of the relay is connected to the wake-up output end of the battery management system. When the battery management system is triggered to wake up by the voltage signal, the relay control coil is energized, causing the relay contacts to close and form a conductive state, and the battery pack outputs voltage again.

[0065] When a contactor is used, the control coil of the contactor is connected to the wake-up output of the battery management system. When the battery management system is triggered to wake up by the voltage signal, the contactor control coil is energized, the main contacts of the contactor are closed and form a conductive state, and the battery pack outputs voltage again.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
