[0034] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein.

[0035] Currently, due to the relatively low cost of lead-acid batteries, they are widely used in vehicles, that is, mainly lead-acid batteries are used as the starting batteries of vehicles to provide electrical energy for vehicle starting.

[0036] However, the starting batteries composed of lead-acid batteries have many drawbacks. For example, they are large in volume, heavy in weight, have a relatively small number of cyclic discharges, short lifespan (generally 2 - 3 years), and their materials are not environmentally friendly; and currently, intelligent management cannot be achieved. In addition, when the vehicle is parked for a long time and the battery is forgotten to be turned off, it is easy to cause the battery to discharge, which brings great inconvenience to the vehicle owner.

[0037] Based on the above existing technical problems, the technical concept of the present invention is as follows: Lithium iron phosphate batteries have the advantages of long cycle life, the number of use times can reach three thousand to six thousand times, high safety, stable structure, not easy to have thermal runaway, and support for fast charging. If lithium iron phosphate batteries can be used as starting batteries, the above-mentioned drawbacks of lead-acid batteries can be solved;

[0038] Furthermore, for using lithium iron phosphate batteries as starting batteries, a method of connecting multiple switch units to functional units respectively can be adopted. The functional units can be devices for heating, cooling, using electrical energy, charging and discharging the battery, etc. And a controller is set. The controller obtains at least one of the attribute data of the lithium iron phosphate battery core and at least one of the user's operation instructions in real time, and generates a control instruction based on this, and sends it to the corresponding switch unit to enable or disable the switch unit, so as to realize the start-stop control of the corresponding functional unit and realize the management and control of the battery.

[0039] Next, the technical solutions of the present invention will be described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0040] Figure 1Structural diagram of the first embodiment of the management system for the starting battery provided by the present invention. As Figure 1 shown, the management system includes: a starting battery system, a control unit, at least one functional unit, and at least one switching unit. The at least one functional unit includes: at least one first functional unit and / or a second functional unit;

[0041] Among them, Figure 1 Taking 3 first functional units as an example for illustration, in actual implementation, based on the addition and reduction of usage functions, the quantity can be adjusted. Correspondingly, the quantity of the switching unit also changes accordingly.

[0042] The starting battery system is respectively connected to at least one functional unit through at least one switching unit, and is used to supply power to at least one first functional unit and / or obtain power from the second functional unit. The at least one functional unit is used to perform temperature regulation, charging management, and / or power consumption of the starting battery system;

[0043] Optionally, the starting battery system can be composed of lithium iron phosphate battery cells. Taking the implementation in a vehicle as an example, the voltage of the starting battery in the vehicle is 12V. Correspondingly, it can be designed as follows: the standard voltage of a single cell can be 3.2V, the capacity can be 2000mA, 10 single cells are connected in parallel as a group, and then 4 groups are connected in series to form a 12V starting battery voltage system.

[0044] The control unit is respectively connected to at least one functional unit through at least one switching unit, and is used to control the on / off state of the target switching unit based on at least one of the attribute data of the lithium iron phosphate battery cells in the starting battery system and at least one of the user's operation instructions, so as to control the state of the target functional unit connected to the target switching unit.

[0045] In this implementation, the control unit can be an STM32 core board RT_Thread OS; the type of the switching unit can be a relay; at least one first functional unit can be: an electrical device (i.e., a 12V device), a cooling device, a low-temperature prevention device (i.e., a heating device), etc.; the second functional unit can be: an in-vehicle charging device (such as an in-vehicle charger).

[0046] Correspondingly, the attribute data can be the temperature information and / or the power information of the lithium iron phosphate battery cells in the starting battery system; if it is temperature information, based on the temperature information, it is determined whether to start the cooling device and / or the low-temperature prevention device, that is, to perform the operation of changing the on / off state of the corresponding switching unit (i.e., the target switching unit); if it is power information, based on the power information, it is determined whether to start the in-vehicle charging device, that is, to perform the operation of changing the on / off state of the corresponding switching unit (i.e., the target switching unit).

[0047] The operation instruction of the user can be based on the function keys of the user in the vehicle, voice instructions, or instructions sent by the user's terminal to the control unit through the corresponding server. The operation instruction carries the identifier of the target functional unit. The control unit determines the corresponding target switch unit based on this identifier and performs on / off operations. For example, when the user needs to park the vehicle for a long time, at this time, the vehicle can be remotely controlled through the terminal to send an operation instruction to the control vehicle to disconnect the power supply to the electrical equipment (turn off the power supply of the starting battery system). At this time, the control unit receives this instruction and changes the on / off state of the switch unit corresponding to the electrical equipment to off.

[0048] Furthermore, Figure 2 It is the structure diagram of the second embodiment of the management system of the starting battery provided by the present invention. As Figure 2 shown, the starting battery system further includes: at least one sampling interface for attribute data ( Figure 2 taking 2 as an example, actually the quantity can be determined based on the number of single cells of the lithium iron phosphate battery or the number of parallel-connected groups); the management system further includes: an acquisition unit;

[0049] The acquisition unit is arranged between at least one sampling interface and the control unit, and is used to acquire at least one attribute data of the lithium iron phosphate battery cell;

[0050] Wherein, at least one attribute data includes: temperature information and / or power information.

[0051] In this implementation, taking the structure of the above starting battery system as an example, when at least one attribute data includes: temperature information, the sampling interface of the starting battery system can be 10 temperature acquisition ports set, that is, J3 in the following Figure 7 , correspondingly, the acquisition unit can include: 10 temperature acquisition sub-units, which acquire the temperature data of each group of batteries and send them to the control unit.

[0052] And, when at least one attribute data includes: power information, the sampling interface of the starting battery system can be two groups of voltage output interfaces set (that is, J1 and J2 in the following Figure 7 ), each group of voltage output interfaces can output 20 single-cell voltages. Correspondingly, the acquisition unit can include: 20 voltage acquisition sub-units, which acquire the voltage data of each group of batteries and send them to the control unit.

[0053] In a possible implementation, a sampling thread can be established in RT_Thread, and a preset frequency can be set (such as collecting once every 50 ms). After passing through the filter, the current temperature information and / or power information can be determined.

[0054] Optionally, the management system further includes: an Ethernet communication module and an external maintenance interface;

[0055] The external maintenance interface is connected to the third device by wire, used to receive the upgrade information in the third device, and send the upgrade information to the control unit through the Ethernet communication module, so that the control unit performs upgrade operations based on the upgrade information.

[0056] In this implementation, when the control strategy in the control unit changes, such as when the number of functional units changes, when the number of battery cells in the battery system starts to change, and when the trigger conditions for turning on and off the functional units are adjusted based on user habits, etc., there will be corresponding changes in the specific implementation of the control of the on-off switch unit (specifically, refer to the following Figures 3 - 6 embodiments).

[0057] In a possible implementation, the user can connect a data cable to the external maintenance interface based on the third device (such as an upgraded operation-related terminal, such as a computer, etc.), and then in response to the upgrade operation of the third device, the Ethernet communication module receives the upgrade information corresponding to the upgrade operation and sends the upgrade information to the control unit. The control unit performs upgrade operations according to the upgrade information to increase the real-time performance and personalized settings of the vehicle, etc.

[0058] Optionally, the management system further includes: a peripheral control circuit; each switch unit respectively includes: a relay and a contactor;

[0059] The control unit is used to generate an on-off instruction for controlling the on-off state of the corresponding target switch unit according to at least one of the attribute data of the lithium iron phosphate battery cells and the operation instruction of the user;

[0060] The peripheral control circuit is arranged between the control unit and at least one switch unit, and is used to provide an adapted voltage signal for executing the on-off of the target contactor by the target relay in the target switch unit according to the on-off instruction.

[0061] In this implementation, when the switch unit is in the form of a relay + contactor combination (that is, the switch unit uses a relay as the signal control device to control the direct on-off device of the contactor for the load), different voltage values need to be given to trigger different relays.

[0062] In a possible implementation, the control unit can generate an on-off instruction for the target switch unit (i.e., the target relay) connected to the functional unit controlled in the operation instruction based on the operation instruction of the user. Since the voltage for controlling the target relay switch is different from the logic level output by the control unit, it is necessary to amplify the signal corresponding to the on-off instruction to the adapted voltage required by the target relay through the peripheral control circuit (such as a triode, MOSFET drive module) to control the on-off of the target contactor.

[0063] It should be understood that for different switch units, that is, the corresponding relays require inconsistent adapted voltage signals, the signals corresponding to the on / off instructions received by the peripheral control circuit are also inconsistent, and the amplified adapted voltages are also inconsistent. Therefore, different relays can be adapted.

[0064] Optionally, a housing unit is externally provided for the management system, and the housing unit is used to protect the management system.

[0065] In this implementation, the housing unit serves as a physical protection layer for the management system and can provide full protection for the electronic components inside the management system (such as the control unit, switch unit, etc.). For example, high-strength materials (such as aluminum alloy, engineering plastics) or metal frame structures can be used to resist the bumps and collisions during vehicle driving (such as road impacts, component resonances), and prevent internal components from being damaged due to mechanical stress (such as circuit board fractures, connector loosening); heat-insulating materials (such as glass fiber-reinforced plastics) or internal heat-conducting silica gels can be selected to block the influence of extreme external temperatures (such as high-temperature engine compartments, low-temperature environments) on electronic components, and at the same time, assist in the dissipation of internal heat through heat dissipation holes or heat dissipation fins to prevent components from failing due to overheating, etc.

[0066] The management system provided by the embodiments of the present invention includes: a starting battery system, a control unit, at least one functional unit, and at least one switch unit. The at least one functional unit includes: at least one first functional unit and / or a second functional unit; the starting battery system is respectively connected to the at least one functional unit through the at least one switch unit, and is used to supply power to the at least one first functional unit and / or obtain power from the second functional unit. The at least one functional unit is used to perform temperature regulation, charging management, and / or power consumption of the starting battery system; the control unit is respectively connected to the at least one functional unit through the at least one switch unit, and is used to control the on / off state of the target switch unit based on at least one attribute data of the lithium iron phosphate battery cell in the starting battery system and / or at least one of the user's operation instructions, so as to control the state of the target functional unit connected to the target switch unit. In this technical solution, the lithium iron phosphate battery cell is used as the battery cell in the starting battery system, which has a long cycle life, can be used more times, has high safety, its structure is stable, is not prone to problems such as thermal runaway, and supports fast charging, etc.; furthermore, during the management of the starting battery system, at least one attribute data of the lithium iron phosphate battery cell and / or the user's operation instructions can be collected in real time, and based on this, the switch unit corresponding to the functional unit is controlled to achieve temperature regulation, charging management, and power consumption of the lithium iron phosphate battery cell in the starting battery system.

[0067] On the basis of the above embodiments, Figure 3 is the structural diagram of the third embodiment of the management system of the starting battery provided by the present invention. As Figure 3As shown, at least one first functional unit includes: an electrical device; the management system further includes: a 4G communication module; at least one switch unit includes: a first switch unit disposed between the electrical device and the starting battery system;

[0068] In this embodiment, in order to avoid events such as power loss caused by the long-term placement of the starting battery system in the vehicle, or when the user needs to use the vehicle after a long time, the power supply of the starting battery system in the vehicle can be cut off or powered on by means of remote control, that is, no electrical energy is supplied to the electrical device or electrical energy is supplied to the electrical device.

[0069] Optionally, the 4G communication module is used to send the operation instruction to the control unit after receiving the operation instruction from the user;

[0070] In this implementation, the user performs the operation of cutting off or supplying power to the electrical device in the terminal device, that is, sends a corresponding operation instruction to the server. The 4G communication module obtains the operation instruction from the server and forwards it to the control unit.

[0071] The control unit is used to control the on / off state of the first switch unit to be closed based on the opening of the electrical device indicated in the operation instruction, so as to control the starting battery system to start the state of supplying power to the electrical device;

[0072] In this implementation, the operation parsed by the control unit from the operation instruction is to turn on the electrical device. At this time, the first switch unit corresponding to the electrical device is controlled to be closed to realize inputting the power of the starting battery system to the electrical device side.

[0073] The control unit is used to control the on / off state of the first switch unit to be disconnected based on the operation instruction indicating that the electrical device is turned off, so as to control the starting battery system to stop supplying power to the electrical device.

[0074] In this implementation, the operation parsed by the control unit from the operation instruction is to turn off the electrical device. At this time, the first switch unit corresponding to the electrical device is controlled to be disconnected to realize disconnecting the input of the power of the starting battery system to the electrical device side.

[0075] It should be understood that in actual implementation, the on / off judgment of the following anti-low temperature device and temperature reduction device can be not considered here. This is because when the vehicle is in the flameout state, the starting battery system is generally in the unused state, and the probability of situations such as too high or too low temperature is relatively small.

[0076] Correspondingly, in some implementations, the on / off judgment of the following anti-low temperature device and temperature reduction device can also be designed and considered, and its implementation principle is similar.

[0077] In the management system provided by the embodiments of the present invention, at least one first functional unit includes: an electrical device; the management system further includes: a 4G communication module; at least one switch unit includes: a first switch unit disposed between the electrical device and the starting battery system; the 4G communication module is configured to send an operation instruction to the control unit after receiving an operation instruction from a user; the control unit is configured to control the on / off state of the first switch unit to be closed based on the electrical device being turned on indicated in the operation instruction, so as to control the starting battery system to turn on and supply power to the electrical device; the control unit is configured to control the on / off state of the first switch unit to be open based on the operation instruction indicating that the electrical device is turned off, so as to control the starting battery system to stop supplying power to the electrical device. In this technical solution, the 4G communication module receives the user operation instruction and transmits it to the control unit, and the control unit controls the on / off of the first switch unit disposed between the electrical device and the starting battery system according to the instruction, realizing the remote control of the power supply state of the starting battery system to the electrical device, enabling the user to remotely turn on or off the starting battery system without approaching the device, significantly improving the use convenience and flexibility, helping to extend the service life of the starting battery system, and enhancing the user experience.

[0078] Based on the above embodiments, Figure 4 is the structural diagram of the fourth embodiment of the management system of the starting battery provided by the present invention. As Figure 4 shown, the management system further includes: a CAN communication module, the second functional unit is an in-vehicle charging device, and at least one switch unit includes: a second switch unit disposed between the in-vehicle charging device and the starting battery system;

[0079] Wherein, at least one attribute data includes: power information.

[0080] The control unit is configured to control the on / off state of the second switch unit to be closed when the power information of the lithium iron phosphate battery cell is obtained to be less than a first power threshold, so as to control the in-vehicle charging device to turn on and supply power to the lithium iron phosphate battery cell;

[0081] In this implementation, after the control unit obtains the power information of the lithium iron phosphate battery cell, it compares it with the first power threshold. The first power threshold can be a power critical value for determining whether to turn on the in-vehicle charging device to supply power to the lithium iron phosphate battery cell (i.e., to prevent battery feed, maintain the battery health state, and improve the battery service life). When the power information is less than the first power threshold, the control unit controls the on / off state of the second switch unit corresponding to the in-vehicle charging device to be closed, thereby realizing charging the lithium iron phosphate battery cell using the in-vehicle charging device.

[0082] The control unit is further configured to control the on / off state of the second switch unit to be off when the power information of the lithium iron phosphate battery cell is greater than the second power threshold, so as to control the in-vehicle charging device to stop supplying power to the lithium iron phosphate battery cell;

[0083] In this implementation, after the control unit obtains the power information of the lithium iron phosphate battery cell, it compares it with the second power threshold. The first power threshold can be the power critical value for determining whether to stop the in-vehicle charging device from supplying power to the lithium iron phosphate battery cell (that is, to prevent overcharging of the battery, maintain the health state of the battery, and improve the service life of the battery). When the power information is greater than the second power threshold, the control unit controls the on / off state of the second switch unit corresponding to the in-vehicle charging device to be off, thereby stopping charging the lithium iron phosphate battery cell using the in-vehicle charging device.

[0084] In a possible implementation, the second power threshold can be 100%, and the first power threshold can be 35%; in actual implementation, the first power threshold and the second power threshold can be adjusted, that is, based on the above implementation of the maintenance interface.

[0085] The CAN communication module is used to send the power information of the lithium iron phosphate battery cell to the vehicle CAN, so that the display unit of the vehicle can display the power information;

[0086] In this implementation, in order to facilitate the user to perceive the power information of the starting battery system in real time, the power information can be sent to the vehicle CAN based on the CAN communication module, and the current power information (i.e., the remaining power information) of the starting battery system can be displayed on the vehicle instrument.

[0087] The management system provided by the embodiment of the present invention further includes: a CAN communication module, the second functional unit is an in-vehicle charging device, and at least one switch unit includes: a second switch unit disposed between the in-vehicle charging device and the starting battery system; the control unit is configured to control the on-off state of the second switch unit to be closed when the power information of the lithium iron phosphate battery cell is obtained to be less than the first power threshold, so as to control the in-vehicle charging device to start supplying power to the lithium iron phosphate battery cell; the control unit is further configured to control the on-off state of the second switch unit to be open when the power information of the lithium iron phosphate battery cell is obtained to be greater than the second power threshold, so as to control the in-vehicle charging device to stop supplying power to the lithium iron phosphate battery cell; the CAN communication module is configured to send the power information of the lithium iron phosphate battery cell to the vehicle CAN, so that the display unit of the vehicle displays the power information; wherein, at least one attribute data includes: power information. This technical solution obtains and transmits the power information of the lithium iron phosphate battery cell through the CAN communication module, and the control unit accurately controls the on-off of the second switch unit disposed between the in-vehicle charging device and the starting battery system based on the power threshold, realizing intelligent charging and discharging control of the lithium iron phosphate battery cell by the in-vehicle charging device. On the one hand, it can effectively avoid overcharging or undercharging of the battery, ensuring the safety performance and service life of the battery; on the other hand, the power information is transmitted to the vehicle CAN through the CAN communication module, enabling the display unit to display the power in real time, facilitating the user to intuitively master the battery state and improving the use convenience; at the same time, this intelligent charging and discharging management and information interaction mechanism enhances the automation and intelligence level of the battery management system and optimizes the vehicle energy management efficiency.

[0088] Based on the above embodiment, Figure 5 is a structural diagram of the fifth embodiment of the management system of the starting battery provided by the present invention. As Figure 5 shown, at least one first functional unit includes: a low-temperature prevention device; at least one switch unit includes: a third switch unit disposed between the low-temperature prevention device and the starting battery system;

[0089] wherein, at least one attribute data includes: temperature information

[0090] The control unit is configured to control the on-off state of the third switch unit to be closed when the temperature information of the lithium iron phosphate battery cell is obtained to be less than the first temperature threshold, so as to control the low-temperature prevention device to start heating the lithium iron phosphate battery cell;

[0091] In this implementation, after the control unit obtains the temperature information of the lithium iron phosphate battery cell in real time, it compares it with the first temperature threshold. When the temperature information is less than the first temperature threshold, it controls the on-off state of the third switch unit corresponding to the low-temperature prevention device to be closed, so that the starting battery system supplies power to the low-temperature prevention device, enabling the low-temperature prevention device to heat the starting battery system.

[0092] Among them, the first temperature threshold is the temperature critical value for determining whether it is necessary to turn on the low-temperature prevention device to heat the lithium iron phosphate battery cell.

[0093] The control unit is further configured to control the on / off state of the third switch unit to be off when the temperature information of the lithium iron phosphate battery cell is greater than the second temperature threshold, so as to control the low-temperature prevention device to stop heating the lithium iron phosphate battery cell;

[0094] In this implementation, after the control unit obtains the temperature information of the lithium iron phosphate battery cell in real time, it compares it with the second temperature threshold. The second temperature threshold can be the upper limit temperature set to maintain the operation of the battery system. When the temperature information is greater than the second temperature threshold, the control unit controls the on / off state of the third switch unit corresponding to the low-temperature prevention device to be off, so that the battery system stops supplying power to the low-temperature prevention device, and the low-temperature prevention device stops heating the battery system.

[0095] Among them, the second temperature threshold is the temperature critical value for determining whether it is necessary to stop the low-temperature prevention device from heating the lithium iron phosphate battery cell.

[0096] In a possible implementation, the second temperature threshold can be 3°C, and the first temperature threshold can be -5°C; in actual implementation, the first temperature threshold and the second temperature threshold can be adjusted, that is, based on the above implementation of the maintenance interface.

[0108] Based on the above embodiments, Figure 7 It is a structural diagram of the seventh embodiment of the management system of the starting battery provided by the present invention. As Figure 7 shown, a practical implemented management system structure is provided.

[0109] In this embodiment, the switching unit is exemplified in the form of a relay. Between the starting battery system and at least one functional unit, a current sensor is further provided. The current sensor is used to monitor the charging and discharging current of the starting battery, and a sensor with an accuracy of 0.4% and a measurement range of 0-800A can be used.

After passing through a filter, the current battery charge load (State of Charge, SOC), that is, the remaining power, is calculated. When the battery SOC reaches 100%, the contactor K1 is disconnected to prevent overcharging of the battery, maintain the healthy state of the battery, and extend the service life of the battery. Information such as battery power and voltage is sent to the vehicle CAN through CAN communication on the main control board, and the remaining power information of the current starting battery can be displayed on the vehicle instrument. When the SOC is lower than 35%, an alarm signal is issued. At the same time, the STM32 core board sends a charging signal to the vehicle through CAN, and the vehicle charges the starting battery through the on-vehicle charger. When the core board detects that the temperature is greater than 72 °C, the relay 2 is activated, the contactor K2 is closed, and the fan is turned on to cool the battery. When the temperature is lower than -5 °C in winter, the relay 3 is activated to start the heating device. When the temperature is higher than 3 °C, the relay 3 is turned off and the contactor K3 is disconnected to stop heating. The relay 4 is remotely controlled and can disconnect the connection path between the battery and 12V.
