In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0032] Combination Figures 1 to 2As shown, according to a specific embodiment of this application, a starting power supply device is provided, including: a module 200, at least one module 200 is disposed, the module 200 includes a plurality of individual battery cells 220, the plurality of individual battery cells 220 are connected in series via a series aluminum busbar 230 to form the module 200, a voltage sampling point 231 is disposed on the series aluminum busbar 230, a positive terminal of the module 200 is connected to a positive aluminum busbar 240, and a negative terminal of the module 200 is connected to a negative aluminum busbar 250, the positive aluminum busbar 240 is electrically connected to the positive terminal 510 of the starting power supply device through a first relay protector, and / or, the negative aluminum busbar 250... 250 is electrically connected to the negative terminal 610 of the starting power supply device through the second relay protector 620; the protection board 300 is electrically connected to the voltage acquisition point 231, the protection board 300 has an acquisition state of acquiring the voltage signal of the series aluminum busbar 230 through the voltage acquisition point 231, the protection board 300 has a first working state of controlling at least one of the first relay protector and the second relay protector 620 to be turned on according to the voltage signal, and the protection board 300 has a second working state of controlling at least one of the first relay protector and the second relay protector 620 to be turned off according to the voltage signal.

[0033] like Figure 2 A side view of a portion of the power supply unit is shown, illustrating the arrangement of individual battery cells 220 within the module 200, as follows: Figure 2 As shown, the direction perpendicular to the plane of the figure and pointing outward is defined as the first direction, and the direction perpendicular to the plane of the figure and pointing outward is defined as the second direction. Figure 2 The battery cells 220 are arranged in three rows, namely the first row, the second row, and the third row along the height. In the first row, the positive terminals of the two leftmost battery cells 220 are placed along a first direction, and the positive terminals of the other two are placed along a second direction. The positive terminals of the other two leftmost battery cells 220 are placed along a second direction, and the positive terminals of the other two are placed along a first direction. The four battery cells 220 in the first row are connected by a series aluminum busbar 230, on which voltage sampling points 231 are provided. The battery cells 220 in the second and third rows are arranged in the same way as in the first row.

[0034] By installing a first relay protector and a second relay protector 620 between the positive aluminum busbar 240 and the negative aluminum busbar 250 and the external terminals, damage to the starting power supply due to external circuit abnormalities or overloads can be effectively prevented. When the protection board 300 detects an abnormal voltage signal, it can immediately control the corresponding relay protector to shut down, cut off the power supply, and avoid potential safety accidents.

[0035] Voltage acquisition point 231 is set on the series aluminum busbar 230 to monitor the voltage status of each individual cell 220 in real time. This is crucial for ensuring the overall performance and health of the battery pack, as any voltage abnormality in a single cell can lead to a decline in the performance or failure of the entire battery pack.

[0036] The protection board 300 is not only responsible for acquiring voltage signals, but also can intelligently control the status of the first and second relay protectors 620 based on the acquired information. This enables the power supply device to automatically respond to changes in external conditions without manual intervention, improving the automation level and convenience of the equipment.

[0037] By employing the technical solution of the above embodiments, continuous monitoring and management of the voltage of the individual battery cells 220 can prevent overcharging and over-discharging, thereby extending the service life of the starting power supply. The combination of voltage acquisition and relay protection ensures that the battery operates within a safe operating range, reducing cell losses.

[0038] By applying the technical solution of this utility model, a voltage acquisition point 231 is set on the series aluminum busbar 230, and the protection board 300 controls at least one of the first relay protector and the second relay protector 620 to open or close according to the voltage signal. This enables the starting power supply to detect the voltage of the individual battery cells 220 in the module 200 for power protection, effectively improving the safety of the starting power supply. The technical solution of this application solves the problem of poor safety in existing starting power supply devices. Furthermore, the technical solution of this application can also transmit the voltage of the individual battery cells 220 to external analysts or equipment via the wireless transmission component 400.

[0039] Furthermore, the power supply device also includes a first temperature sensor 700, which is connected to one side of the module 200 and electrically connected to the protection board 300. The protection board 300 has a third operating state in which it controls at least one of the first relay protector and the second relay protector 620 to be turned on based on the voltage signal and the temperature signal detected by the first temperature sensor 700. The protection board 300 also has a fourth operating state in which it controls at least one of the first relay protector and the second relay protector 620 to be turned off based on the voltage signal and the temperature signal.

[0040] Besides voltage anomalies, temperature is also a crucial factor affecting battery performance and safety. By continuously monitoring the temperature of the individual battery cell 220 and its surrounding environment, the protection board 300 can intelligently control the relay protector when the temperature is too high or too low, preventing the battery from operating under extreme temperatures and thus avoiding the risk of thermal runaway or battery freezing.

[0041] The addition of the first temperature sensor 700 enables the power supply device to provide early warnings of overheating or overcooling, allowing users or the system to take preventative measures, such as activating the cooling or heating system, to keep the battery within its optimal operating temperature range and reduce potential malfunctions and maintenance needs.

[0042] Battery temperature has a direct impact on cell lifespan. By controlling the battery's operating temperature, the lifespan of individual cells can be significantly extended, thereby improving the overall durability of the starting power supply.

[0043] Batteries operate at higher efficiency and energy output when within a suitable temperature range. Therefore, by controlling the temperature, the starting power unit can supply the energy required for starting more efficiently, optimizing vehicle starting performance.

[0044] By combining voltage and temperature monitoring, the protection board 300 can more accurately determine the battery's status and achieve more intelligent power management. For example, when both battery temperature and voltage are within safe ranges, the starter power supply can provide optimal startup performance; once an abnormality is detected, immediate measures can be taken, such as activating the protection mechanism or sending an alarm to the user.

[0045] If the power supply is equipped with a Bluetooth module, the temperature signal can be transmitted wirelessly to the user's mobile device along with the voltage signal, allowing the user to not only monitor the voltage status but also to know the battery temperature at any time, thus achieving comprehensive remote monitoring of the power supply.

[0046] Furthermore, the power supply device also includes a wireless transmission component 400, which is connected to the module 200 and electrically connected to the protection board 300. The wireless transmission component 400 has a signal transmission mode that transmits at least one of voltage signal, temperature signal, and charge value signal to an external device. The charge value signal is obtained by the protection board 300 detecting the module 200.

[0047] By incorporating a wireless transmission component 400 into the power supply unit and electrically connecting it to the module 200 and protection board 300, the unit can transmit voltage signals, temperature signals, and State of Charge (SOC) signals to external devices. This design offers the following significant advantages:

[0048] The wireless transmission component 400 enables users or monitoring systems to obtain critical status information of the startup power supply in real time via external devices. This includes battery voltage, temperature, and state of charge, allowing users to remotely monitor and manage the startup power supply from anywhere.

[0049] With real-time monitoring by external devices, users can receive an immediate alarm and take necessary measures if the voltage, temperature, or charge value of the power supply exceeds safe limits. For example, if the temperature is too high, users can remotely control the power supply to enter cooling mode to avoid potential safety risks.

[0050] The signals received by external devices are not limited to real-time monitoring; they can also be used for data analysis to predict battery health and potential faults. By recording and analyzing voltage, temperature, and charge data over a long period, predictive models of battery performance can be established, allowing for proactive maintenance or battery replacement to avoid sudden failures.

[0051] Users can check the current charge level of the power bank using external devices, allowing them to better plan its usage and charging strategies. For example, when the charge level is low, it can be pre-charged to ensure the power bank is always fully charged when needed.

[0052] Wireless transmission allows users to access critical information without physical contact with a power source, significantly improving ease of use and security. This wireless monitoring and management capability is particularly beneficial in electric vehicles, greatly optimizing the user experience. Wireless monitoring reduces reliance on physical connections, lowering device complexity and cost. Simultaneously, remote diagnostics and maintenance capabilities reduce the need for on-site service, lowering maintenance costs.

[0053] Furthermore, there are multiple modules 200, including a first module and a second module. The first module and the second module are connected in series. The first module is formed by multiple battery cells 220 connected in series, and the second module is formed by multiple battery cells 220 connected in series. At least one battery cell 220 in the first module has a positive terminal at its end, and at least one battery cell 220 in the second module has a negative terminal at its end.

[0054] The voltage of each individual battery cell 220 is fixed, but by connecting multiple cells 220 in series, their voltages can be superimposed, thereby significantly improving the voltage output capability of the starting power supply. This is crucial for electric vehicle starting power supplies, as they need to provide sufficient voltage to start the motor and other high-power components.

[0055] The design using multiple modules (first module and second module) allows for dynamic adjustment of the number and configuration of modules according to the specific needs of the startup power supply, making the system design more flexible. If a higher voltage is required, more modules can be added in series; if a larger capacity is required, the number of individual cells within the module can be increased.

[0056] In a series-connected module setup, even if one module or individual cell fails, the other modules can continue to operate and provide the necessary voltage. This increases the reliability of the starting power supply, ensuring that the vehicle can still be started in critical situations.

[0057] Module 200 is designed as an independently operable unit, making maintenance and replacement easier. If a single cell in the first or second module fails, the faulty module can be replaced individually without replacing the entire starting power system.

[0058] By monitoring the voltage of the individual cells 220 in the first and second modules respectively, the protection board 300 can implement a more refined battery balancing management strategy. This balancing management ensures that all individual cells operate under similar conditions, avoiding overcharging or over-discharging of individual cells, thereby improving the overall battery pack performance and lifespan. Furthermore, the positive electrode aluminum busbar 240 is electrically connected to the positive terminal 510 via a fuse 520, and the negative electrode aluminum busbar 250 is electrically connected to the negative terminal 610 via a second relay protector 620.

[0059] As overcurrent protection devices, fuse 520 and second relay 620 can quickly melt or disconnect the circuit in the event of an abnormally large increase in current, preventing safety accidents such as overheating, fire, and short circuit. During startup or in the event of a battery failure, the current may suddenly increase to a dangerous level; the fuse and relay can promptly cut off the current, protecting equipment and personnel safety.

[0060] Fuses and relays provide an extra layer of isolation and protection between the positive and negative terminals. This design prevents direct short circuits between the positive and negative terminals and ensures that the internal circuitry of the battery remains undamaged even in extreme cases (such as when an external conductor short-circuits the positive and negative terminals), thus extending the lifespan of the starting power supply.

[0061] The design of the fuses and relays allows for rapid identification and replacement of the fuse or reset of the relay after an overcurrent event, without the need to replace the entire starting power supply or perform complex repairs. This not only reduces maintenance costs but also shortens repair time and improves equipment availability.

[0062] The second relay protector 620 acts as a controllable switch, which can be intelligently controlled by the protection board 300 based on battery status information (such as voltage and temperature) to dynamically adjust the current output. This intelligent management helps avoid battery overcharging or over-discharging, extends battery life, and optimizes starting performance.

[0063] Through the control of the protection board 300, the second relay protector 620 can participate in more complex circuit control logic, such as battery health status assessment, fault detection and early warning, and remote operation. This enables the starting power supply device to be better integrated into the intelligent vehicle management system, providing a higher level of functionality and user experience.

[0064] Furthermore, multiple battery cells 220 within the module 200 are arranged in an array. Multiple battery cells 220 located in the same row are connected in series via a series aluminum busbar 230. Multiple series aluminum busbars 230 connected to battery cells 220 in different rows are connected in series. At least one of the multiple series aluminum busbars 230 is provided with a voltage sampling point 231.

[0065] like Figure 1 and Figure 2 As shown, the module includes multiple cell groups, and each cell group includes multiple individual cells. The positive electrode of an individual cell located in the same cell group is electrically connected to the positive electrode of the other individual cells in the same cell group, and the negative electrode of an individual cell located in the same cell group is electrically connected to the negative electrode of the other individual cells in the same cell group.

[0066] Figure 2 This only illustrates one possible implementation of the cell arrangement. It should be noted that the cell arrangement is solely for improving the module's output parameters; for any arrangement, the power supply can be monitored and controlled using a protection board. To ensure the module's output parameters meet expectations, at least two cells (multiple cells connected positive-positive and negative-negative) are typically electrically connected to increase the output voltage. Such a group of at least two cells is called a cell group; multiple cell groups are connected in series via positive and negative connections to form a module. In this embodiment, the positive-positive and negative-negative connections within a cell group are achieved using a series aluminum busbar, and the positive and negative connections between multiple cell groups are also achieved using a series aluminum busbar. For example, if one cell group includes two cells, and another cell group also includes two cells, to achieve positive-positive and negative connections within the cell group, as well as series connections between the two cell groups, a series aluminum busbar connects four cells.

[0067] Furthermore, the power-starting device includes a cover 100 and a housing 800, which are connected and form a receiving cavity between them. The power-starting device includes a second temperature sensor, which is connected to at least one of the cover 100 and the housing 800 and is electrically connected to the protection plate 300.

[0068] Furthermore, the wireless transmission component 400 includes at least one of a WIFI component, an Ethernet component, a Bluetooth component, and a ZIGBEE component.

[0069] The Wi-Fi component enables the jump starter to communicate with nearby devices connected to Wi-Fi networks, such as home routers and in-vehicle Wi-Fi hotspots. This provides broader application scenarios for remote monitoring and data transmission of the jump starter, especially in environments with stable Wi-Fi networks, such as garages or repair shops. Users can monitor battery status via the network, achieving stable signal transmission and real-time data updates even when the jump starter is physically far from the user's device.

[0070] Ethernet components provide a wired communication method between power supply units and fixed network devices, such as connecting to a vehicle's central control system or a factory's monitoring system. This connection method typically offers higher data transmission rates and lower latency than wireless communication, making it suitable for applications requiring large amounts of data exchange or real-time control. The high stability of Ethernet communication also makes it a reliable choice for ensuring data transmission quality while the vehicle is in motion or in harsh environments.

[0071] Bluetooth components are a common choice for short-range wireless communication between power supply devices and user mobile devices. They enable real-time transmission of power supply status information (such as voltage, temperature, and charge), making them ideal for everyday vehicle status monitoring. Bluetooth's low-power characteristics mean it doesn't significantly impact the power supply's battery life, and its broad compatibility allows for seamless connectivity with most modern mobile devices.

[0072] ZIGBEE components offer a low-power, long-range, low-latency wireless communication method, particularly suitable for monitoring power supplies outdoors or when vehicles are far from user equipment. ZIGBEE networks maintain signal stability and security in complex environments, ensuring the transmission of critical data even with low battery levels. Furthermore, ZIGBEE's network topology allows for reliable data transmission within a large network of devices, making it ideal for centralized monitoring systems in fleet management or large vehicle maintenance centers.

[0073] By integrating wireless transmission technologies such as Wi-Fi, Ethernet, Bluetooth, and ZigBee into the wireless transmission component 400, the power supply unit can select the most suitable communication method according to different application environments and needs. For example, when the vehicle is parked in a home garage, it can be monitored in real time via Wi-Fi or Bluetooth; while the vehicle is in motion, it can switch to ZigBee or Bluetooth to maintain the connection; in repair shops or fleet management scenarios, Ethernet or ZigBee can provide high-bandwidth and high-stability data transmission services.

[0074] Furthermore, through intelligent software scheduling, the protection board 300 can automatically select the optimal communication method based on network conditions and data requirements, thereby achieving seamless, efficient, and safe remote monitoring and management of the starter power supply. This flexible and intelligent communication design greatly enhances the functionality and user-friendliness of the starter power supply, making it a significant innovation in the field of electric vehicle starter power supplies.

[0075] In one embodiment, the power supply device can preset a priority list, such as Bluetooth > WIFI > ZIGBEE > Ethernet. When the connection quality of the current optimal communication method (such as Bluetooth) is detected to be degraded, the protection board 300 can automatically switch to the next priority communication method (such as WIFI) to ensure the continuity and stability of data transmission.

[0076] In an optional embodiment, Figure 1 This is a schematic diagram of the power supply structure. Figure 1 As can be seen, the battery cell 220, the battery cell bracket 210, and the series aluminum busbar 230 are connected by screws to form the module 200; each of the series aluminum busbars 230 is provided with a voltage acquisition point 231, and the voltage acquisition point 231, the wireless transmission component 400, the first temperature sensor 700, and the protection board 300 are all connected by wires; the negative electrode component 600 includes a negative terminal 610 and a second relay protector 620, and the positive electrode component 500 includes a positive terminal 510 and a fuse 520; the negative electrode component 600 and the positive electrode component 500 are connected to the external load and the module 200; the outermost part of the battery is the cover 100 and the casing 800, which are connected by screws.

[0077] Working principle: Module 200 supplies power to protection board 300 via wires. Once powered on, protection board 300 controls the opening and closing of negative electrode assembly 600, thereby controlling the power supply to external loads. Simultaneously, voltage acquisition point 231 on the series aluminum busbar 230 provides a voltage signal to protection board 300 via wires. Protection board 300 calculates the voltage of each cell 220 by obtaining the voltage signals from both the positive and negative terminals. The first temperature sensor 700 provides real-time temperature information to protection board 300 after module 200 is powered on. Battery voltage and temperature information can be transmitted to a mobile phone via wireless transmission component 400, enabling data transfer.

[0078] like Figure 1As shown, individual battery cells 220 are placed on a battery cell support 210. The individual battery cells 220 are connected together using series aluminum busbars 230, and the series aluminum busbars 230 are fixed in place with nuts, thus forming a module 200. Similar modules 200 are placed nearby. Modules 200 are connected to each other via aluminum busbars. The two ends of two connected modules are respectively a positive aluminum busbar 240 and a negative aluminum busbar 250. The two modules 200 are fixed to the housing 800 using screws. Each series aluminum busbar 230 has a voltage acquisition point 231. A voltage acquisition line is connected to the series aluminum busbar 230 at the voltage acquisition point 231 using screws. The other end of the voltage acquisition line is connected to the protection board 3. The protection board 300 receives the voltage signal from the voltage acquisition line and calculates the voltage of the battery cell 220 by calculating the voltage difference between the positive and negative terminals of the battery cell 220. The first temperature sensor 700 is set on both sides of the module and is fixed by adhesive. The temperature signal is transmitted to the protection board 300 through wires. The protection board 300 is fixed to one side of the module by screws. The module 200 directly supplies power to the protection board 300. The wireless transmission component 400 is glued to the side of the module and connected to the protection board 300 through wires. External Bluetooth devices, such as mobile phones, can know the battery status information, such as voltage, temperature, and SOC, through Bluetooth connection.

[0079] The starting power supply has positive and negative terminals for connecting external devices. A fuse 520 is provided between the positive aluminum busbar 240 and the positive terminal 510 of the starting power supply for safety protection. Both connections are made using screws. The positive terminal 510 and the fuse 520 together form the positive terminal assembly 500. A second relay protector 620 is provided between the negative aluminum busbar 250 and the negative terminal 610. Both connections are made using screws. The second relay protector 620 is controlled by the protection board 300. By controlling the second relay protector 620, the starting power supply can be controlled. The negative terminal 610 and the second relay protector 620 together form the negative terminal assembly 600.

[0080] The lid 100 and the body 800 are connected by screws.

[0081] According to another aspect of the present invention, a vehicle is provided, including a starting power supply device, wherein the starting power supply device is the aforementioned starting power supply device.

[0082] Voltage and temperature are crucial technical parameters when using a power supply. However, due to the simple structure and limited functionality of existing starting power supplies, certain problems arise during installation and subsequent use.

[0083] 1. The internal temperature of the casing or the temperature of the battery cells cannot be determined during the use of the power supply;

[0084] 2. The voltage of a single battery cell cannot be determined during the use of the power supply;

[0085] 3. Communication between the user and the power supply is difficult during use.
