[0042] Developing new energy and replacing traditional energy with new energy is the main way to solve the current energy supply and demand bottleneck and reduce environmental pressure, and is also the basic guarantee for sustainable development. As an important part of sustainable development, new energy vehicles will become the mainstream direction of the vehicle industry.

[0043] At present, battery replacement technology can be used to replace batteries in electric vehicles such as heavy trucks to replenish energy for electric vehicles with insufficient energy. When replacing batteries, for example, after the battery system such as part of the battery module is disassembled, or when the battery system is installed and the electric vehicle is not started, quickly and accurately obtaining the status information of the battery system is one of the current issues of concern.

[0044] In view of this, an embodiment of the present application provides a high-voltage box and a control method for the high-voltage box. The high-voltage box is applied to a battery system, and the battery system also includes a battery cell connected to the high-voltage box.

[0051] It should be understood that the technical solutions described in the embodiments of the present application are not limited to the devices described above, but can also be applied to all devices using batteries. However, for the sake of simplicity, the following embodiments are described using electric vehicles as examples.

[0052] Figure 1 A schematic diagram of an electric vehicle provided in an embodiment of the present application.

[0053] The vehicle 1 may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended range vehicle, etc. A motor 40, a controller 30 and a battery system 10 may be arranged inside the vehicle 1, and the controller 30 is used to control the battery system 10 to supply power to the motor 40. For example, the battery system 10 may be arranged at the bottom, front or rear of the vehicle 1.

[0054] The battery system 10 can be used to power the vehicle 1. In some embodiments, the battery system 10 can be used as an operating power source for the vehicle 1 and for the circuit system of the vehicle 1, for example, for starting, navigating, and operating the vehicle 1.

[0055] In some embodiments, the battery system 10 may also serve as a driving power source for the vehicle 1 , replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1 .

[0056] In order to meet different power requirements, the battery system 10 may include multiple battery cells, wherein the multiple battery cells may be connected in series, in parallel, or in hybrid connection, where hybrid connection refers to a mixture of series connection and parallel connection. For example, multiple battery cells may be connected in series, in parallel, or in hybrid connection to form a battery module, and multiple battery modules may be connected in series, in parallel, or in hybrid connection to form a battery. In other words, multiple battery cells may be directly connected to form a battery, or may be first connected to form a battery module, and then the battery module may be connected to form a battery.

[0057] Figure 2 This is an architectural diagram of the battery system provided in an embodiment of the present application.

[0058] The battery system 10 may include a battery cell 11 and a high voltage box 12 .

[0059] In some embodiments, the battery unit 11 may include one or more battery cells.

[0060] In some embodiments, the high voltage box 12 may be disposed on the battery cell 11. For example, the battery cell 11 may include a box body and a box cover, and the high voltage box 12 may be disposed on the box cover of the battery cell 11.

[0061] In some embodiments, the high voltage box 12 may be connected to the battery cell 11, and the connection method may include one or more of mechanical connection, electrical connection, or communication connection. For example, the high voltage box 12 may be connected to the battery cell 11 by mechanical connection methods such as welding, riveting, or gluing. Of course, the high voltage box 12 may be directly connected to the battery cell 11, or the high voltage box 12 may be indirectly connected to the battery cell 11 through other components.

[0062] In some embodiments, the high voltage box 12 may include high voltage components such as high voltage relays, high voltage fuses, etc., through which high voltage input and output of the battery unit 11 can be achieved.

[0063] In some embodiments, the high voltage box 12 may include a battery control module for implementing management and monitoring of the battery. For example, the battery control module may include a battery management unit (BMU) that can determine state parameters such as current, voltage, or state of charge (SOC) of the battery cell 11 to control charging or discharging of the battery system 10.

[0064] In some embodiments, the battery unit 11 may further include a slave management unit for collecting information such as current, voltage or SOC of the battery cells in the battery unit 11 .

[0065] The battery control module can communicate with the slave battery management unit to obtain information such as the battery cell current, voltage or SOC in the battery unit 11, so as to determine the state parameters such as the current, voltage or SOC of the battery unit 11. Optionally, the battery control module can also obtain the state parameters such as the current, voltage or SOC of the battery unit 11 by communicating with the high-voltage component.

[0066] In some embodiments, the battery control module may also communicate with other components of the high voltage box 12 , such as a direct current / direct current (DC / DC) conversion module, to implement charge and discharge control of the battery system 10 .

[0067] That is, in the embodiment of the present application, the high voltage box 12 may be used in the battery system 10 , and the battery system 10 may further include a battery cell 11 connected to the high voltage box 12 .

[0068] like Figure 3 As shown, the high voltage box 12 may include: a processing module 121 and a display module 122. The processing module 121 is used to determine the state parameters of the battery system 10 and send the state parameters to the display module 122; the display module 122 is used to receive the state parameters and display the state parameters.

[0069] The state parameters of the battery system 10 may be understood as the state parameters in the battery unit 11 , for example, SOC information and current information of the battery unit 11 or temperature information of the battery cells in the battery unit 11 .

[0070] The high voltage box 12 provided in the embodiment of the present application can accurately and quickly display the status parameters of the battery system 10 through the display module 122, thereby improving the user experience. At the same time, the status parameters of the battery system 10 can be presented without the need for an external high voltage box 12 or any device other than the battery system 10.

[0071] In some embodiments, Figure 4As shown, the battery unit 11 may also include a slave management unit 112, which may be used to collect information such as the SOC, current, and temperature of the battery cell 111. The processing module 121 may communicate with the slave management unit 112 to obtain information such as the SOC, current, and temperature of the battery cell 111, thereby determining the state parameters of the battery system 10.

[0072] In some embodiments, the processing module 121 may communicate with a battery management unit in the high voltage box 12 to obtain state parameters of the battery system 10. Alternatively, the processing module 121 may be a battery management unit.

[0073] The processing module 121 may be integrated with the battery management unit, or may be provided separately.

[0074] In an embodiment of the present application, the processing module 121 is a circuit with signal processing capability. In one implementation, the processing module 121 may be a circuit with instruction reading and execution capability, such as a central processing unit (CPU), a microprocessor, etc.; in another implementation, the processing module 121 may implement certain functions through the logical relationship of a hardware circuit, and the logical relationship of the hardware circuit is fixed or reconfigurable, such as a hardware circuit in which the processor is implemented as an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field programmable gate array (FPGA).

[0075] In some embodiments, the processing module 121 is further used to control the battery unit 11 to supply power to the display module 122 .

[0076] Or, if Figure 5 As shown, the high voltage box 12 may further include a low voltage battery 123 , and the processing module 121 is further used to control the low voltage battery 123 to supply power to the display module 122 .

[0077] The display module 122 needs electricity when receiving the status parameters of the battery system 10 and displaying the status parameters. Therefore, the energy of the battery unit 11 can be transmitted to the display module 122 to power the display module 122 .

[0078] The voltage of the low-voltage battery 123 is relatively low, generally much lower than the voltage of the electric box 11. For example, the voltage of the low-voltage battery 123 is 12V, and the voltage of the electric box 11 can be between 200V and 700V. The power and voltage required by the display module 122 are generally relatively low, and the power supply of the low-voltage battery 123 can basically guarantee the power demand of the display module 122.

[0079] As an example, when there is a low-voltage battery 123 in the high-voltage box 12 , the display module 122 may be powered by only the low-voltage battery 123 .

[0080] In an embodiment of the present application, in an embodiment of the present application, the battery unit 11 or the low-voltage battery 123 can be used to power the display module 122, so that the display module 122 can promptly receive the status parameters of the battery system 10 and promptly display the status parameters of the battery system 10, thereby improving the user experience.

[0081] In some embodiments, the processing module 121 is used to: when the low-voltage battery 123 is in a non-undervoltage state, control the low-voltage battery 123 to supply power to the display module 122; or, when the low-voltage battery 123 is in an undervoltage state, control the battery unit 11 to supply power to the display module 122.

[0082] When the low-voltage battery 123 is in an undervoltage state, the low-voltage battery 123 cannot supply power to the display module 122. As an example, when the voltage of the low-voltage battery 123 is less than or equal to the undervoltage threshold, the low-voltage battery 123 is in an undervoltage state; otherwise, the low-voltage battery 123 is in a non-undervoltage state. Alternatively, when the power of the low-voltage battery 123 is less than the undervoltage power (such as the SOC of the low-voltage battery 123 < 5%), the low-voltage battery 123 is in an undervoltage state; otherwise, the low-voltage battery 123 is in a non-undervoltage state.

[0083] When the low-voltage battery 123 is not in an undervoltage state, the display module 122 can be powered by the low-voltage battery 123. When the low-voltage battery 123 is in an undervoltage state, the display module 122 can be powered by the battery unit 11.

[0084] In an embodiment of the present application, a low-voltage battery 123 in a non-undervoltage state can be used to promptly and stably supply power to the display module 122, so that the display module can promptly receive the status parameters of the battery system 10 and display the status parameters in a timely manner; or, when the low-voltage battery 123 is in an undervoltage state, that is, the low-voltage battery 123 cannot supply power to the display module 122, the battery cell 11 can also be used to supply power to the display module 122, so that the display module 122 can present the status parameters of the battery system 10 to the user, thereby improving the user experience.

[0085] In some embodiments, the high-voltage box 12 also includes a first DC / DC conversion module 124, which is arranged between the battery unit 11 and the display module 122, and the processing module 121 is used to control the battery unit 11 to supply power to the display module 122 through the first DC / DC conversion module 124.

[0086] Since the voltage provided by the battery unit 11 is relatively high, while the voltage required by the display module 122 is relatively low, the first DC / DC conversion module 124 is required to convert the high voltage into a low voltage to meet the use requirement of the display module 122 .

[0087] In the embodiment of the present application, the first DC / DC conversion module 124 is used to realize the power supply of the battery unit 11 to the display module 122 to meet the power demand of the display module 122, so that the display module 122 receives the status parameters of the battery system 10 and displays the status parameters, thereby improving the user experience.

[0088] In some embodiments, the processing module 121 is further used to control the battery unit 11 to charge the low-voltage battery 123 .

[0089] As an example, when the low-voltage battery 123 is in an undervoltage state, the low-voltage battery 123 may be charged by using the battery unit 11 .

[0090] If the display module 122 also needs electricity at this time, for example, the display module 122 needs to display the status parameters of the battery system 10, the battery unit 11 can be controlled to supply power to the low-voltage battery 123 and the display module 122 at the same time. Optionally, the battery unit 11 can be controlled to supply power to the display module 122 first, and after the display module 122 is powered, the battery unit 11 is controlled to supply power to the low-voltage battery 123.

[0091] In an embodiment of the present application, when the low-voltage battery 123 is in an undervoltage state, the battery unit 11 is used to charge the low-voltage battery 123 so that the low-voltage battery 123 can meet the power requirements of the display module 122, etc., thereby improving the user experience.

[0092] In some embodiments, Figure 5 As shown, the high voltage box 12 includes a second DC / DC conversion module 125, which is arranged between the battery unit 11 and the low voltage battery 123, and the processing module 121 is used to control the battery unit 11 to charge the low voltage battery 123 through the second DC / DC conversion module 125.

[0093] Since the voltage provided by the battery unit 11 is relatively high, and the voltage of the low-voltage battery 123 during charging is relatively low, it is necessary to utilize the second DC / DC conversion module 125 to convert the high voltage into a low voltage to meet the charging requirement of the low-voltage battery 123 .

[0094] In the embodiment of the present application, the second DC / DC conversion module 125 is used to realize the charging of the low-voltage battery 123 by the battery unit 11, thereby reducing the damage when the battery unit 11 directly charges the low-voltage battery 123, thereby improving the performance and life of the low-voltage battery 123.

[0095] In some embodiments, Figure 6 As shown, the high-voltage box 12 also includes a third DC / DC conversion module 126, which is arranged between the battery unit 11 and the display module 122 and between the battery unit 11 and the low-voltage battery 123. The processing module 121 is used to control the battery unit 11 to supply power to the display module 122 and / or the low-voltage battery 123 through the third DC / DC conversion module 126.

[0096] The battery unit 11 can supply power to the display module 122 or the low-voltage battery 123 alone through the third DC / DC conversion module 126, or the battery unit 11 can supply power to the display module 122 or the low-voltage battery 123 at the same time through the third DC / DC conversion module 126. For example, when the low-voltage battery 123 is in an undervoltage state and the display module 122 has no power demand, the battery unit 11 can supply power to the low-voltage battery 123 through the third DC / DC conversion module 126; or, when the low-voltage battery 123 is in an undervoltage state and the display module 122 has a power demand, the battery unit 11 can supply power to the display module and the low-voltage battery 123 at the same time through the third DC / DC conversion module 126.

[0097] In the embodiment of the present application, the third DC / DC conversion module 126 can be used to realize the battery unit 11 to power the display module 122 and / or the low-voltage battery 123, which can reduce the damage when the battery unit 11 directly powers the display module 122 and / or the low-voltage battery 123, improve the performance and life of the display module 122 and / or the low-voltage battery 123, and can also reduce the occupancy of the internal space of the high-voltage box 12 by the DC / DC conversion module, thereby reducing the size of the high-voltage box 12.

[0098] In some embodiments, the processing module 121 is used to: determine the state parameters of the battery system 10 in response to a user's operation and send the state parameters to the display module 122, wherein the operation is used to request display of the state parameters.

[0099] Accordingly, the display module 122 may receive the status parameter and display the status parameter.

[0100] As an example, a button may be set on the battery system 10, and the user may operate by pressing the button. For example, the user may request to display the state parameters of the battery system 10 by pressing the button on the display module 122. The display module 122 may send the information requesting to display the state parameters to the processing module 121, and the processing module 121 may determine the current state parameters of the battery system 10 and send the state parameters to the display module 122 for display.

[0101] As another example, the user may also operate on a terminal device associated with the battery system 10 , such as a mobile phone, to request the display of status parameters.

[0102] In the embodiment of the present application, the status parameters of the battery system 10 can be displayed through the display module 122 in response to the user's request to present the status parameters of the battery system 10, thereby meeting the user's needs and improving the user experience.

[0103] In some embodiments, the processing module 121 is further used to: in response to another operation of the user, stop sending the state parameter to the display module 122, where the other operation is used to request to stop displaying the state parameter.

[0104] Accordingly, the display module 122 stops receiving the status parameter.

[0105] As an example, a button may be set on the battery system 10, and the user may perform the other operation by pressing the button. For example, the user may request to stop displaying the status parameter by pressing a button on the display module 122. The display module 122 may send the request information to the processing module 121, and the processing module 121 may stop determining the current status parameter of the battery system 10, and send the stop status parameter to the display module 122.

[0106] As another example, the user may also perform another operation on a terminal device associated with the battery system 10 to implement an operation of requesting to stop displaying the status information.

[0107] In the embodiment of the present application, by responding to the user's request to present the status parameters of the battery system 10 and stopping sending the status parameters from the processing module 121 to the display module 122, the data overhead between the processing module 121 and the display module 122 can be reduced.

[0108] In some embodiments, the processing module 121 is further used to: in response to another operation of the user, control the battery unit 11 to stop supplying power to the display module 122 , where the other operation is used to request to stop displaying the status parameters.

[0109] In the case that the display module 122 is powered only by the battery unit 11 , when the user performs the other operation, the processing module 121 may control the battery unit 11 to stop supplying power to the display module 122 .

[0110] As an example, a button may be set on the battery system 10, and the user may operate by pressing the button. For example, the user may request to stop displaying the status parameter by pressing a button on the display module 122. The display module 122 may send the information requesting to stop displaying the status parameter to the processing module 121, and the processing module 121 may control the battery unit 11 to stop supplying power to the display module 122.

[0111] As another example, the user may also operate on a terminal device associated with the battery system 10 to stop supplying power to the display module 122 .

[0112] The processing module 121 may stop the battery unit 11 from supplying power to the display module 122 by disconnecting the circuit between the battery unit 11 and the display module 122 , for example, by disconnecting the switch of the first DC / DC conversion module 124 .

[0113] In the embodiment of the present application, when the user requests to stop displaying the status parameters of the battery system 10 , the power supply from the battery unit 11 to the display module 122 may be disconnected to save energy.

[0114] In some embodiments, the processing module 121 is further used to: in response to another operation of the user, control the low-voltage battery 123 to stop supplying power to the display module 122 , and the other operation is used to request to stop displaying the status parameters.

[0115] In the case that the display module 122 is powered only by the low-voltage battery 123 , when the user performs the other operation, the processing module 121 may control the low-voltage battery 123 to stop supplying power to the display module 122 .

[0116] As an example, a button may be set on the battery system 10, and the user may perform the other operation by pressing the button. For example, the user may request to stop displaying the status parameter by pressing a button on the display module 122. The display module 122 may send the information requesting to stop displaying the status parameter to the processing module 121, and the processing module 121 may control the low-voltage battery 123 to stop supplying power to the display module 122.

[0117] As another example, the user may also perform an operation on a terminal device associated with the battery system 10 to stop supplying power to the display module 122 .

[0118] The processing module 121 can stop the battery unit 11 from supplying power to the display module 122 by disconnecting the circuit between the low-voltage battery 123 and the display module 122 , for example, turning off the power of the low-voltage battery 123 .

[0119] In the embodiment of the present application, when the user requests to stop displaying the status parameters of the battery system 10 , the power supply of the low-voltage battery 123 to the display module 122 can be disconnected to save energy consumption.

[0120] In some embodiments, the processing module 121 is used to: in response to another operation of the user, determine the power supply source of the display module 122, the power supply source is the low-voltage battery 123 or the battery cell 11 in the high-voltage box 12, and the other operation is used to request to stop displaying the status parameters; when the power supply source of the display module 122 is the low-voltage battery 123, control the low-voltage battery 123 to stop supplying power to the display module 122; or, when the power supply source of the display module 122 is the battery cell 11, control the battery cell 11 to stop supplying power to the display module 122.

[0121] In the case where the battery unit 11 or the low-voltage battery 123 can both supply power to the display module 122, it is necessary to determine whether the battery unit 11 or the low-voltage battery 123 is currently supplying power to the display module 122. As an example, the power supply source of the display module 122 can be determined by judging whether the battery unit 11 and / or the low-voltage battery 123 is currently in a working state. For example, if the low-voltage battery 123 is in a working state, it can be considered that the low-voltage battery 123 is currently supplying power to the display module 122, and the processing module 121 can control the low-voltage battery 123 to stop supplying power to the display module 122.

[0122] In an embodiment of the present application, when the user requests to stop displaying the status parameters of the battery system 10, it is possible to first determine whether the power supply source of the display module 122 is the battery cell 11 or the low-voltage battery 123, so that the battery cell 11 or the low-voltage battery 123 can be accurately controlled to stop supplying power to the display module 122 to save energy.

[0123] In some embodiments, the battery cell 11 includes a battery cell, and the status parameter includes one or more of the following parameters: fault information of the battery cell 11, voltage information of the battery cell 11, SOC of the battery cell 11, power of the battery cell 11, voltage information of the battery cell 111 in the battery cell 11, and temperature information of the battery cell 111 in the battery cell 11.

[0124] In an embodiment of the present application, by presenting to the user one or more of the fault information of the battery cell 11, the voltage information of the battery cell 11, the state of charge SOC information of the battery cell 11, the power information of the battery cell 11, the voltage information of the battery cell 11 in the battery cell 11, and the temperature of the battery cell 111 in the battery cell 11, the performance and life of the battery system 10 can be accurately determined, which facilitates determining whether the battery system 10 can meet the power demand of the electrical equipment, thereby improving the user experience.
