Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a device and vehicle for detecting the status of a vehicle battery. Background Technology

[0002] In related technologies, in order to ensure that the vehicle can start normally, the system needs to be actively woken up at regular intervals to check the state of charge of the battery. This not only consumes the energy of the entire vehicle and causes unnecessary energy waste, but also makes it easy for users to forget to disconnect the battery power, resulting in the vehicle being depleted and reducing the battery's lifespan. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0004] Therefore, one objective of this invention is to provide a device for detecting the status of a vehicle battery. This device can remind the user to disconnect the battery power when the vehicle is parked, ensuring that the battery has sufficient energy reserves for the next start of the vehicle. This effectively prevents the battery from being depleted due to user negligence in forgetting to turn off the power, thus significantly extending the battery's lifespan and avoiding damage caused by frequent deep discharges. Furthermore, the control module, in sleep mode, can effectively reduce energy consumption and extend battery life.

[0005] Therefore, the second objective of this utility model is to provide a vehicle.

[0006] To achieve the above objectives, an embodiment of the first aspect of this utility model discloses a device for detecting the state of a vehicle battery, comprising: a sensor module connected to the battery for detecting the temperature and state of charge of the battery; and a control module connected to the sensor module for receiving the temperature and state of charge of the battery sent by the sensor module, and switching from a dormant state to an operating state when the state of charge is lower than or equal to a first alarm threshold and / or a second alarm threshold corresponding to the temperature of the battery, and sending a first prompt signal indicating that the state of charge is too low, and / or sending a second prompt signal indicating that the state of charge is too low, wherein the power consumption of the control module in the dormant state is lower than its power consumption in the operating state, and the first alarm threshold is greater than the second alarm threshold.

[0007] According to an embodiment of the present invention, a device for detecting the state of a vehicle battery includes a sensor module connected to both the battery and a control module. The sensor module detects the battery's temperature and state of charge (SOC), transmitting these values ​​to the control module. Based on the current battery temperature and its corresponding SOC, the control module compares the SOC with a first alarm threshold and / or a second alarm threshold. When the SOC is lower than or equal to the first and / or second alarm thresholds, the control module adaptively wakes up, switching from a low-power sleep state to a working state. It then issues a first warning signal indicating a low SOC and / or a second warning signal indicating an excessively low SOC, reminding the user to disconnect the battery power when the vehicle is parked. This ensures the battery has sufficient energy reserves for the next vehicle start-up, effectively preventing battery depletion due to user negligence in forgetting to turn off the power, thus significantly extending battery life and avoiding damage caused by frequent deep discharges. Furthermore, the control module effectively reduces energy consumption and extends battery life when in sleep mode.

[0008] In addition, the device for detecting the state of a vehicle battery according to the above embodiments of the present invention may also have the following additional technical features:

[0015] In some embodiments, the data platform is also communicatively connected to a user terminal to transmit the first alarm notification information and / or the second alarm notification information to the user terminal so that the user terminal can display the first alarm notification information and / or the second alarm notification information.

[0016] In some embodiments, the control module is further configured to: switch from the operating state to the dormant state when the state of charge is higher than a first alarm threshold and / or a second alarm threshold corresponding to the temperature of the battery.

[0017] To achieve the above objectives, a second aspect of the present invention discloses a vehicle including a device for detecting the state of a vehicle battery as described in the first aspect of the present invention.

[0018] According to the vehicle embodiment of this utility model, the sensor module is connected to both the battery and the control module. It can detect the battery's temperature and state of charge (SOC), and transmit these measurements to the control module. The control module compares the SOC with a first alarm threshold and / or a second alarm threshold based on the current battery temperature and its corresponding SOC. When the SOC is lower than or equal to the first and / or second alarm thresholds, the control module adaptively wakes up, switching from a low-power sleep state to a working state. It then issues a first warning signal indicating a low SOC and / or a second warning signal indicating an excessively low SOC, reminding the user to disconnect the battery power when the vehicle is parked. This ensures the battery has sufficient energy reserves for the next vehicle start-up, effectively preventing battery depletion due to user negligence in forgetting to turn off the power, thus significantly extending battery life and avoiding damage caused by frequent deep discharges. Furthermore, the control module effectively reduces energy consumption and extends battery life when in sleep mode.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:

[0021] Figure 1 This is a schematic diagram of a device for detecting the state of a vehicle battery according to an embodiment of the present invention;

[0022] Figure 2 This is a structural block diagram of a vehicle according to an embodiment of the present invention. Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0024] The following is for reference. Figure 1 This invention describes an apparatus for detecting the state of a vehicle battery according to an embodiment of the present invention.

[0025] Figure 1 This is a schematic diagram of a device for detecting the state of a vehicle battery according to an embodiment of the present invention. Figure 1 As shown, the device 100 for detecting the status of a vehicle battery includes a sensor module 110 and a control module 120.

[0026] Specifically, such as Figure 1 As shown, sensor module 110 is connected to the battery and is used to detect the battery temperature and state of charge (SOC). Control module 120 is connected to sensor module 110 and is used to receive the battery temperature and SOC sent by sensor module 110. When the SOC is lower than or equal to a first alarm threshold and / or a second alarm threshold corresponding to the battery temperature, control module 120 switches from sleep state to working state and sends a first alert signal indicating low SOC, and / or sends a second alert signal indicating excessively low SOC. The power consumption of control module in sleep state is lower than its power consumption in working state, and the first alarm threshold is greater than the second alarm threshold.

[0027] Among them, the state of charge refers to the remaining amount of electricity in the battery.

[0028] In an embodiment, such as Figure 1 As shown, the sensor module 110 is connected to the battery to continuously monitor the battery temperature and the remaining battery power.

[0029] The control module 120 is connected to the sensor module 110 to receive real-time data on the battery's temperature and state of charge transmitted by the sensor module 110. Based on this data, the control module 120 can intelligently determine the current condition of the battery.

[0030] Specifically, when the state of charge of the battery drops to or below an alarm threshold, the alarm threshold includes two levels: a first alarm threshold and a second alarm threshold. As the battery temperature changes, the first alarm threshold and the second alarm threshold will also be continuously adjusted. In other words, the battery will have its own corresponding first alarm threshold and / or second alarm threshold at different temperatures, thereby ensuring that the state of charge of the battery under different temperature conditions can be reflected more accurately, and the first alarm threshold is higher than the second alarm threshold.

[0031] Once the battery's state of charge (SCC) falls below or equals the first alarm threshold and / or the second alarm threshold, the control module 120, which was originally in a low-power sleep state, will be activated and switch to a higher-power operating state. In this state, the control module 120 will immediately issue an alarm signal. If the SCC is low, a first alarm signal will be sent; if the SCC is already too low, a second alarm signal will be sent, or both alarm signals may be sent simultaneously depending on the situation. These alarm signals are used to remind the user to disconnect the battery, ensuring sufficient energy for the vehicle's next start. This effectively prevents the battery from running out of power due to the user forgetting to disconnect the power, thus effectively extending the battery's lifespan.

[0032] In a specific embodiment, the control module 120 stores the correspondence between the temperature of the battery and the alarm threshold, and different battery temperatures correspond to different first alarm thresholds and / or second alarm thresholds.

[0033] Specifically, multiple batteries of the same specification are prepared, with varying degrees of aging to simulate the diversity of real-world use. Next, through a series of tests, alarm thresholds for the state of charge (SOC) required for the starter motor to operate normally at different battery temperatures are identified. These SOC alarm thresholds are then input into the control module 120, enabling the sensor module 110 to detect the SOC corresponding to the current battery temperature and transmit it to the control module 120. When the SOC is lower than or equal to the first alarm threshold and / or the second alarm threshold stored in the control module 120 for the current battery temperature, the control module 120 automatically wakes up, switching from a dormant state to an operating state and simultaneously activating the vehicle network to promptly take charging or other maintenance measures.

[0034] Furthermore, to verify and expand the applicability of the results, another set of batteries of the same specification with different aging levels will be prepared to repeat the above test. Finally, based on these test data, alarm thresholds will be determined for batteries of different specifications and aging levels. These alarm thresholds will be used as the adaptive wake-up thresholds of the control module 120, thereby achieving accurate monitoring and intelligent management of the battery status.

[0035] Therefore, the aforementioned device 100 for detecting the vehicle battery status, with sensor module 110 connected to the battery and control module 120 respectively, can detect the battery temperature and state of charge (SOC), and transmit the detected SOC to control module 120. Based on the current battery temperature and its corresponding SOC, control module 120 compares the SOC with a first alarm threshold and / or a second alarm threshold. When the SOC is lower than or equal to the first alarm threshold and / or the second alarm threshold, control module 120 adaptively wakes up, that is, switches from a low-power sleep state to a working state, and issues a first warning signal indicating a low SOC, and / or a second warning signal indicating an excessively low SOC, to remind the user to disconnect the battery power in time when the vehicle is parked. This ensures that the battery has sufficient energy reserves for the next start of the vehicle, thereby effectively preventing the battery from being depleted due to the user's negligence in forgetting to turn off the power, thus significantly extending the battery's service life and avoiding damage caused by frequent deep discharge. In addition, the control module 120 can effectively reduce energy consumption and extend the battery life when in sleep mode.

[0036] In one embodiment of this utility model, the sensor module 120 is mounted on the negative terminal of the battery.

[0037] In this embodiment, the sensor module 120 is mounted on the negative terminal of the battery, forming a direct electrical connection between the sensor module 120 and the negative terminal of the battery. This allows for real-time and accurate monitoring of the current, voltage, or other relevant electrical parameters of the battery's negative terminal. By directly mounting the sensor module 120 on the negative terminal of the battery, not only is the immediacy and accuracy of data acquisition ensured, but errors and delays that may occur during wiring or signal transmission are also effectively reduced. Furthermore, this mounting method helps save space, making the overall design more compact and efficient, while also facilitating maintenance and replacement.

[0038] In one embodiment of this utility model, such as Figure 1 As shown, the device 100 for detecting the status of a vehicle battery also includes a communication module 130, which is connected to the control module 120 via a bus, for receiving and forwarding a first alert signal and / or a second alert signal.

[0039] In an embodiment, such as Figure 1As shown, the communication module 130 establishes a stable data transmission channel with the control module 120 via a bus. When the remaining battery power is lower than or equal to the first alarm threshold, the communication module 130 receives a first prompt signal sent by the control module 120, and / or when the remaining battery power is lower than or equal to the second alarm threshold, the communication module 130 receives a second prompt signal sent by the control module 120, and forwards the first and / or second prompt signals to notify the user of the battery's state of charge. This allows the user to take corresponding measures based on the prompt signals, thereby ensuring that the vehicle battery is always in optimal working condition, and thus improving the overall performance and safety of the vehicle.

[0040] In one embodiment of the present invention, the communication module 130 includes a gateway.

[0041] In this embodiment, the gateway, through its powerful protocol conversion capabilities, achieves seamless integration between the device's internal data and the control module 120 or other modules. It can not only receive the first and second alert signals from the vehicle battery status detection device, but also convert and encapsulate these signals according to the target system's protocol requirements, ensuring accurate information transmission. Simultaneously, the gateway possesses packet filtering and security functions, providing security for data transmission. Furthermore, the gateway's routing and data forwarding capabilities enable efficient and stable information transmission in complex network environments, thereby improving the overall performance and reliability of the detection device. This not only enhances the device's communication capabilities but also improves the security and efficiency of data transmission, providing strong support for real-time monitoring and maintenance of the vehicle battery status.

[0042] In one embodiment of this utility model, such as Figure 1 As shown, the device 100 for detecting the status of a vehicle battery also includes: an alarm module 140, connected to the communication module 130, for receiving a first prompt signal and / or a second prompt signal, displaying corresponding first alarm prompt information and / or second alarm prompt information, and issuing corresponding alarm prompt signals.

[0043] In this embodiment, the alarm module 140 is connected to the communication module 130. When the communication module 130 receives a first and / or second alert signal from the control module 120, it forwards these alert signals to the alarm module 140. Upon receiving the first alert signal, the alarm module 140 immediately displays a first alarm message on the display interface, such as clearly indicating "Battery power is low" in text or an icon. It also issues a low battery warning signal via sound, light, or other means, providing a dual reminder to the user that the battery is low and needs to be charged promptly. Similarly, if the alarm module 140 receives a second alert signal, it displays a second alarm message on the display interface, such as "Battery power is too low," accompanied by a strong alarm signal, warning the user that the battery power is severely insufficient and immediate action must be taken to prevent vehicle breakdown or other potential safety issues caused by a depleted battery, thus ensuring the user can respond quickly and take appropriate action.

[0044] In one embodiment of this utility model, the alarm module 140 includes a vehicle dashboard.

[0045] In this embodiment, using the vehicle dashboard to display and issue alarms not only improves the integration of vehicle information but also greatly enhances safety and convenience during driving.

[0046] For example, when the sensor module 110 detects an abnormal situation such as low or excessively low remaining battery power, the vehicle's instrument panel can immediately display corresponding alarm information, such as through character displays, clearly conveying the battery's current status to the driver. Simultaneously, the instrument panel may also be equipped with an audible alarm function, emitting a clear and recognizable alarm sound to further alert the driver to battery issues. This allows the driver to quickly grasp the battery's status without being distracted by checking other devices or displays, enabling timely charging or other necessary maintenance measures to ensure driving safety and enhance the driving experience.

[0047] In one embodiment of this utility model, such as Figure 1 As shown, the device 100 for detecting the status of a vehicle battery further includes a processing module 150 and a data platform 160. The processing module 150 is connected to the communication module 130 and is used to receive a first prompt signal and / or a second prompt signal, and to forward the corresponding first alarm prompt information and / or second alarm prompt information. The data platform 160 is communicatively connected to the processing module 150 and is used to receive the first alarm prompt information and / or the second alarm prompt information, and to store and display the first alarm prompt information and / or the second alarm prompt information.

[0048] The processing module 150 is, for example, a T-BOX (Telematics BOX, vehicle communication terminal).

[0049] In this embodiment, the processing module 150 serves as the hub for information processing and is connected to the communication module 130. When the communication module 130 receives the first prompt signal and / or the second prompt signal, it forwards the signal to the processing module 150. The processing module 150 quickly analyzes these signals and generates corresponding first alarm prompt information and / or second alarm prompt information accordingly.

[0050] Meanwhile, the processing module 150 is also connected to the data platform 160 to forward the generated first alarm message and / or second alarm message to the data platform 160. After receiving the first alarm message and / or second alarm message, the data platform 160 will not only store these alarm messages securely and reliably for subsequent data analysis and fault diagnosis, but also display these alarm messages in an intuitive and clear manner through its user interface, so that vehicle maintenance personnel or drivers can quickly understand the current state of charge of the battery and take necessary maintenance measures in a timely manner to ensure the normal operation of the vehicle battery and driving safety.

[0051] In one embodiment of this utility model, such as Figure 1 As shown, the data platform 160 is also connected to the user terminal for transmitting the first alarm prompt information and / or the second alarm prompt information to the user terminal so that the user terminal can display the first alarm prompt information and / or the second alarm prompt information.

[0052] User terminals include, for example, smartphones, tablets, or dedicated monitoring equipment.

[0053] In this embodiment, the data platform 160 is not only capable of efficiently processing and analyzing various types of data, but also has the ability to establish real-time communication connections with user terminals. This enables the data platform 160 to quickly generate a first alarm message and / or a second alarm message when it detects specific conditions or abnormal situations, and push the first alarm message and / or the second alarm message to the user terminal.

[0054] Once the user terminal receives these alarm notifications, they will be displayed clearly and intuitively on the screen immediately, ensuring that the user receives the alarm notifications as soon as possible. This greatly improves the timeliness and accuracy of information transmission, enabling the user to react quickly and effectively deal with possible emergencies or problems, thereby ensuring the stability and safety of the vehicle.

[0055] In one embodiment of the present invention, the control module 120 is further configured to switch from the working state to the dormant state when the state of charge is higher than a first alarm threshold and / or a second alarm threshold corresponding to the temperature of the battery.

[0056] In this embodiment, when the state of charge of the battery is higher than a first alarm threshold and / or a second alarm threshold corresponding to the current battery temperature, the control module 120 can adaptively and smoothly switch from the normal operating state to a low-power sleep state.

[0057] Specifically, the control module 120 stores the correspondence between battery temperature and alarm thresholds. Based on the battery temperature and state of charge detected by the sensor module 110, the control module 120 can determine the corresponding first alarm threshold and / or second alarm threshold. When the battery's state of charge exceeds the first alarm threshold and the second alarm threshold, the control module 120 will adaptively enter a sleep state.

[0058] In hibernation mode, most vehicle components cease operation except for necessary monitoring and maintenance functions, thereby effectively reducing energy consumption, extending battery life, and providing additional safety protection for the vehicle.

[0059] In summary, according to the embodiment of the present invention, the device 100 for detecting the state of a vehicle battery has a sensor module 110 connected to both the battery and the control module 120. It can detect the battery's temperature and state of charge (SOC), and transmit these to the control module 120. The control module 120 compares the SOC with a first alarm threshold and / or a second alarm threshold based on the current battery temperature and its corresponding SOC. When the SOC is lower than or equal to the first and / or second alarm thresholds, the control module 120 adaptively wakes up, switching from a low-power sleep state to a working state, and issues a first warning signal indicating a low SOC, and / or a second warning signal indicating an excessively low SOC. This reminds the user to disconnect the battery power when the vehicle is parked, ensuring the battery has sufficient energy reserves for the next start of the vehicle. This effectively prevents battery depletion due to user negligence in forgetting to turn off the power, significantly extending battery life and avoiding damage caused by frequent deep discharges. In addition, the control module 120 can effectively reduce energy consumption and extend the battery life when in sleep mode.

[0060] The present invention also proposes a vehicle 200 in the embodiments.

[0061] like Figure 2The diagram shown is a structural block diagram of a vehicle according to an embodiment of the present invention. The vehicle 200 includes a device 100 for detecting the state of the vehicle battery as described in any of the above embodiments of the present invention.

[0062] It should be noted that when the vehicle 200 performs vehicle battery status detection, its specific implementation method is similar to that of the device 100 for detecting vehicle battery status in any of the above embodiments of this utility model. Therefore, for a detailed exemplary description of the process of the vehicle 200 performing vehicle battery status detection, please refer to the relevant description of the device 100 for detecting vehicle battery status mentioned above. To reduce redundancy, it will not be repeated here.

[0063] According to the vehicle 200 of this embodiment, the sensor module 110 is connected to both the battery and the control module 120. It can detect the battery temperature and state of charge (SOC), and transmit the detected SOC to the control module 120. The control module 120 compares the SOC with a first alarm threshold and / or a second alarm threshold based on the current battery temperature and its corresponding SOC. When the SOC is lower than or equal to the first and / or second alarm thresholds, the control module 120 adaptively wakes up, switching from a low-power sleep state to a working state, and issues a first warning signal indicating a low SOC, and / or a second warning signal indicating an excessively low SOC. This reminds the user to disconnect the battery power when the vehicle is parked, ensuring the battery has sufficient energy reserves for the next vehicle start-up. This effectively prevents battery depletion due to user negligence in forgetting to turn off the power, significantly extending battery life and avoiding damage caused by frequent deep discharges. Furthermore, in sleep mode, the control module 120 effectively reduces energy consumption and extends battery life.
