[0002] Due to various reasons, the electrode components in the battery may experience insufficient upper electrolyte in the late or even early stages of the cycle, resulting in poor wetting, which in turn causes lithium plating and seriously affects the safety of the battery.

[0003] Summary of the Invention

[0004] In view of the above problems, embodiments of the present application provide a method and device for installing a battery, as well as an operating device, which can improve the safety of the battery.

[0005] In a first aspect, a method for installing a battery is provided, comprising: obtaining first installation information of the battery, the first installation information including information of the first side of the battery facing upward when the battery was last installed or removed; generating second installation information of the battery based on the first installation information, the second installation information being used to indicate that the second side of the battery should be facing upward for the next installation, wherein the second side is the side opposite to the first side.

[0006] In an embodiment of the present application, by obtaining the first side of the battery that was facing upward when it was last installed or removed, second installation information can be generated to instruct the battery to be installed next time with the second side opposite to the first side facing upward. This allows the first side and the second side of the battery to be installed alternately facing upward, which is beneficial to solving the problem of insufficient electrolyte at the upper end of the electrode assembly in the battery, thereby improving the safety of the battery.

[0007] In some embodiments, when the first surface is facing upward, the second installation information indicates that the battery should be turned 180 degrees along a first direction, where the first direction is perpendicular to the direction of gravity.

[0008] In this embodiment, the battery is flipped 180 degrees along the first direction according to the second installation information, so that the battery can be flipped from the first side facing up to the second side opposite to the first side facing up, thereby enabling the first side and the second side of the battery to be installed alternately facing up, which is beneficial to solving the problem of insufficient electrolyte at the upper end of the electrode assembly in the battery and improving the safety of the battery.

[0009] In some embodiments, the second installation information indicates that the battery should be turned 180 degrees along the first direction after the battery was last removed.

[0010] In this way, you only need to flip the battery after the last disassembly, and the others do not need to be flipped again.

[0011] In some embodiments, the second installation information indicates that the battery should be turned 180 degrees along the first direction before the battery is installed again.

[0012] In this way, the battery only needs to be turned over before the battery is installed next time, and does not need to be turned over at other times.

[0013] In some embodiments, the method further includes: determining the first direction according to a setting position of a same-polarity electrical interface of the battery.

[0014] In this embodiment, the first direction of battery flipping is determined based on the setting position of the same-polarity electrical interface of the battery, so that after the battery is flipped 180 degrees along the first direction, the battery still has an electrical interface of corresponding polarity at the position where it is electrically connected to the electrical device, so as to be electrically connected to the electrical device, thereby providing electrical energy to the electrical device.

[0015] In some embodiments, determining the first direction based on the setting position of the same-polarity electrical interface of the battery includes: if the same-polarity electrical interface of the battery is symmetrically arranged on the wall of the battery box along the center line of the length direction of the battery, the first direction is the length direction of the battery.

[0016] In this embodiment, when the same-polarity electrical interfaces of the battery are symmetrically arranged on the wall of the battery along the center line of the length direction, after the battery is flipped 180 degrees along the length direction, the battery still has an electrical interface of the corresponding polarity at the position where it is electrically connected to the electrical device, so as to be electrically connected to the electrical device, thereby providing electrical energy to the electrical device.

[0017] In some embodiments, determining the first direction based on the setting position of the same-polarity electrical interface of the battery includes: if the same-polarity electrical interface of the battery is symmetrically arranged on the wall of the battery box along the center line of the width direction of the battery, the first direction is the width direction of the battery.

[0018] In this embodiment, when the same-polarity electrical interfaces of the battery are symmetrically arranged on the wall of the battery along the center line in the width direction, after the battery is flipped 180 degrees in the width direction, the battery still has an electrical interface of corresponding polarity at the position where it is electrically connected to the electrical equipment, so as to be electrically connected to the electrical equipment, thereby providing electrical energy to the electrical equipment.

[0020] In this embodiment, the second installation information can be generated only when the battery status information meets specific conditions, and it does not have to be generated before each battery installation. In this way, there is no need to flip the battery before each battery installation, which can improve the mechanical strength and life of the operating device used to install or remove the battery.

[0021] In some embodiments, generating the second installation information according to the first installation information and the battery status information includes: generating the second installation information when the cumulative depth of discharge of the battery after the last flip is greater than 200%.

[0022] This allows the electrolyte to evenly penetrate the entire electrode assembly, thereby solving the problem of lithium deposition caused by excessive depth of discharge and improving battery safety. In addition, this eliminates the need to flip the battery before each reinstallation, which can improve the mechanical strength and life of the operating device.

[0023] In some embodiments, generating the second installation information according to the first installation information and the battery status information includes: generating the second installation information when a sampling temperature of a battery cell in the battery is greater than 40 degrees or less than 10 degrees.

[0024] This allows the electrolyte to evenly penetrate the entire electrode assembly, thus resolving the problem of uneven electrolyte solution caused by excessively high battery cell temperatures and improving battery safety. Furthermore, this eliminates the need to flip the battery before each reinstallation, which improves the mechanical strength and lifespan of the operating device.

[0025] In some embodiments, generating the second installation information according to the first installation information and the status information of the battery includes: generating the second installation information when the number of fast charges of the battery reaches 2 times after the last flip.

[0026] This allows the electrolyte to evenly penetrate the entire electrode assembly, thereby resolving the lithium deposition problem caused by excessive fast charging and improving battery safety. Furthermore, this eliminates the need to flip the battery before each reinstallation, which improves the mechanical strength and lifespan of the operating device.

[0027] In some embodiments, generating the second installation information according to the first installation information and the status information of the battery includes: generating the second installation information when the battery has been stationary for more than 500 hours since the last flip.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0079] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by technicians in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0080] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0081] With the development of new energy technologies, the application areas of batteries are becoming more and more extensive. For example, they can be used as a power source to provide power for electrical equipment, reducing the use of non-renewable resources. When the power of the battery in the electrical equipment is not enough to support the continued driving of the electrical equipment, the electrical equipment can be charged using charging equipment such as charging piles, that is, the battery in the electrical equipment can be directly charged to achieve the charge and discharge cycle of the battery. Alternatively, battery replacement services can be provided for electrical equipment through battery swap stations, that is, the battery can be quickly removed or installed from the electrical equipment. The battery removed from the electrical equipment can be placed in the battery storage mechanism of the battery swap station for charging, so that it can be replaced with power for subsequent electrical equipment entering the battery swap station.

[0082] However, after the battery has been used in the same state for a period of time or a certain number of cycles, due to various reasons, such as gravity, there will be insufficient electrolyte at the upper end of the electrode assembly within the battery cell, resulting in poor wetting, which in turn causes lithium plating and seriously affects the safety of the battery.

[0083] In view of this, an embodiment of the present application provides a method for installing a battery. By alternately installing the first side of the battery and the second side opposite to the first side facing upward, it is helpful to solve the problem of insufficient electrolyte at the upper end of the electrode assembly in the battery and improve the safety of the battery.

[0084] The battery referred to in the embodiments of this application refers to a single physical module consisting of one or more battery cells with a higher voltage and capacity. For example, the battery referred to in this application may include a battery pack. A battery generally includes a housing for enclosing one or more battery cells. The housing prevents liquids or other foreign matter from affecting the charging and discharging of the battery cells.

[0085] A battery cell includes an electrode assembly and an electrolyte. The electrode assembly consists of a positive electrode sheet, a negative electrode sheet, and a separator. A battery cell primarily operates by the movement of metal ions between the positive and negative electrode sheets. The positive electrode sheet comprises a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive current collector. The current collector uncoated with the positive active material layer protrudes from the current collector coated with the positive active material layer, and the current collector uncoated with the positive active material layer serves as the positive electrode tab. For lithium-ion batteries, for example, the positive current collector can be made of aluminum, and the positive active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide. The negative electrode sheet comprises a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative current collector. The current collector uncoated with the negative active material layer protrudes from the current collector coated with the negative active material layer, and the current collector uncoated with the negative active material layer serves as the negative electrode tab. The negative current collector can be made of copper, and the negative active material can be carbon or silicon, among others. To ensure that high currents can flow without melting, the positive electrode tabs are multiple and stacked together, and the negative electrode tabs are multiple and stacked together. The separator can be made of polypropylene (PP) or polyethylene (PE).

[0086] To meet different power requirements, a battery can include multiple battery cells, where the multiple battery cells can be connected in series, parallel, or in a hybrid connection. Hybrid connection refers to a mixture of series and parallel connections. Optionally, multiple battery cells can first be connected in series, parallel, or in a hybrid connection to form a battery module, and multiple battery modules can then be connected in series, parallel, or in a hybrid connection to form a battery. In other words, multiple battery cells can be directly combined into a battery, or they can first be combined into battery modules, and then the battery modules can be combined into a battery. The battery is further installed in an electrical device to provide power to the device.

[0087] Figure 1 shows a schematic diagram of an application scenario of battery replacement according to an embodiment of the present application. As shown in Figure 1, the application scenario of battery replacement may involve a battery swap station 11, an electrical device 12, and a battery.

[0088] The battery swap station 11 may refer to a location that provides battery swap services for electrical equipment. For example, the battery swap station 11 may be a fixed location, or the battery swap station 11 may be a mobile device such as a mobile battery swap device, which is not limited here.

[0089] The power-consuming device 12 can be detachably connected to the battery. In some examples, the power-consuming device 12 can be a car, truck, motorcycle, special vehicle, or other vehicle powered by a power battery, or a device powered by a power battery, such as a battery-swappable ship or aircraft.

[0090] The battery may include a battery provided in the electric device 12 and a battery located in the battery swap station 11 for battery swapping. For ease of distinction, as shown in FIG1 , the battery to be replaced in the electric device 12 is recorded as battery 141, and the battery used for battery swapping in the battery swap station is recorded as battery 142. The battery may be a lithium-ion battery, a lithium metal battery, a lead-acid battery, a nickel-cathode battery, a nickel-hydrogen battery, a lithium-sulfur battery, a lithium-air battery or a sodium-ion battery, etc., but is not limited here. In terms of scale, the battery may be a battery cell, a battery module or a battery pack, but is not limited here. In addition to being used as a power source to power the motor of the electric device 12, the battery can also power other electric devices in the electric device 12. For example, the battery can also power the air conditioner, the car player, etc. in the car.

[0091] When the electric device 12 equipped with battery 141 enters the battery swap station 11, the battery swap station 11 removes the battery 141 from the electric device 12 through the battery swap device, removes the battery 142 from the battery swap station 11, and then installs the battery 142 on the electric device 12. The electric device 12 equipped with battery 142 can then leave the battery swap station 11. This battery swap technology allows electric devices to be quickly recharged in minutes or even tens of seconds, improving the user experience.

[0092] As shown in Figure 1, a battery swap cabinet 13 may be provided in the battery swap station 11. The battery swap cabinet 13 includes a first battery management module 131 and a charging module 132. The battery swap cabinet 13 may also be provided with multiple charging compartments 133, and the batteries used for battery swapping may be placed in the charging compartments 133 of the battery swap cabinet 13 of the battery swap station 11. The first battery management module 131 may be a battery management module provided in the battery swap cabinet 13. For example, the first battery management module 131 may be referred to as a central battery management module (CBMU). The charging module 132 may charge the batteries in the charging compartment 133. In some examples, the charging module may include an AC / DC module, i.e., an AC / DC module, and other components, devices, or equipment with charging functions, which are not limited here. The charging module 132 may be provided in a one-to-one correspondence with the charging compartment 133, or multiple charging compartments 133 may share one charging module 132, which is not limited here.

[0093] The battery may be provided with a corresponding second battery management module 143. For example, the second battery management module 143 may be referred to as a slave battery management module (SBMU).

[0094] The electric device 12 is further provided with a third battery management module 121. The third battery management module 121 can be used to manage multiple batteries 141 installed on the electric device. For example, the third battery management module 121 can be called a main battery management unit (MBMU).

[0095] In some embodiments, the SBMU may be implemented using the battery management system (BMS) of the corresponding battery; the MBMU may be implemented through a control module of a battery disconnect unit (BDU) or through the BMS of one of the batteries.

[0096] The battery swap station 11 may also be provided with a corresponding management device. The management device may be a centralized structure or a distributed structure, which is not limited here. The management device may be arranged inside the battery swap station 11 or outside the battery swap station 11. In the case where the management device is a distributed structure, the management device may also be partially arranged inside the battery swap station 11 and partially arranged outside the battery swap station 11. For example, as shown in Figure 1, the management device may include a station control system 151 inside the battery swap station 11 and a cloud server 152 outside the battery swap station 11, which is not limited here. The station control system 151 can also be referred to as a battery management module in the battery swap station 11, which is used to manage and control the batteries 142 in the battery swap station 11.

[0097] Optionally, the first battery management module 131 can communicate and interact with other modules, modules, devices, etc. via wired or wireless means. The second battery management module 143 can communicate and interact with other modules, modules, devices, etc. via wired or wireless means. The third battery management module 121 can communicate and interact with other modules, modules, devices, etc. via wired or wireless means. The station control system 151 can communicate and interact with other modules, modules, devices, etc. via wired or wireless means. Wired communication means include, for example, a CAN communication bus. Wireless communication means include, for example, Bluetooth communication, WiFi communication, ZigBee communication, and various other means, which are not limited herein.

[0098] For example, the first battery management module 131 can communicate with the second battery management module 143 to control the charging of the battery 142 in the battery compartment 133. For another example, the third battery management module 121 can communicate with the second battery management module 143 to centrally manage multiple batteries 141 on the power-consuming device 12. For another example, the station control system 151 can communicate with the first battery management module 131, the second battery management module 143, or the third battery management module 121 to obtain relevant information about the battery 141 on the power-consuming device 12 or the battery 142 in the charging compartment 133. For another example, the station control system 151 can also communicate with the cloud server 152 to obtain relevant information about the battery 141 on the power-consuming device 12 or the battery 142 in the charging compartment 133.

[0099] Figure 2 is a schematic flow chart of a method 200 for installing a battery provided in an embodiment of the present application. The method 200 for installing a battery can realize flipping the battery once every period of time, so that every part of the electrode assembly in the battery can be fully infiltrated by the electrolyte at intervals, reducing the lithium plating phenomenon caused by insufficient infiltration of the electrode assembly, thereby improving the safety of the battery. The method 200 for installing a battery can be executed by the battery management system of the battery, or the station control system 151 and the cloud server 152 in the battery swap station 11 in Figure 1 above. As shown in Figure 2, the method 200 for installing a battery includes some or all of the following contents.

[0103] As shown in FIG3 , the battery 300 may include a first surface 301 and a second surface 302 . The first surface 301 and the second surface 302 may be arranged relative to each other along a gravity direction Z when the battery 300 is installed in an electrical device.

[0104] In one embodiment, when the battery 300 was last installed or removed, the upward-facing side of the battery 300 may be recorded as the first side 301, thereby obtaining first installation information of the battery 300. When it is determined that the upward-facing side of the battery 300 during the last installation or removal was the first side 301, second installation information may be generated. This second installation information may instruct the battery 300 to be installed with the second side 302 facing upward for the next installation, thereby controlling the battery 300 to be installed alternately with the first side 301 and the second side 302.

[0105] Accordingly, in an optional embodiment, the operating device may actively obtain the second installation information, and then operate the battery 300 according to the second installation information, so that the battery 300 is installed with the second surface 302 facing upward.

[0106] In an embodiment of the present application, the operating device can be a device specifically used to install or remove batteries in the battery swap station 11 of Figure 1, or it can be an independent device for installing or removing batteries, such as an automated guided vehicle (AGV).

[0107] Accordingly, in another optional embodiment, the operating device may receive the second installation information, and then operate the battery 300 according to the second installation information, so that the battery 300 is installed with the second surface 302 facing upward.

[0108] In an embodiment of the present application, by obtaining the first side of the battery that was facing upward when it was last installed or removed, second installation information is generated to instruct the battery to be installed next time with the second side opposite to the first side facing upward. This allows the first side and the second side of the battery to be installed alternately facing upward, which is beneficial for solving the problem of insufficient electrolyte at the upper end of the electrode assembly in the battery, thereby improving the safety of the battery.

[0109] According to some embodiments of the present application, optionally, when the first surface is facing upward, the second installation information indicates that the battery should be flipped along a first direction, where the first direction is perpendicular to the direction of gravity.

[0110] It should be understood that the first side facing upwards refers to the first side that was facing upwards when the battery was last installed or removed.

[0111] Optionally, as shown in FIG3 , when the battery 300 is a rectangular parallelepiped structure, the first direction may be a length direction X or a width direction Y of the battery 300 .

[0112] In an optional embodiment, the operating device can flip the battery 180 degrees along the first direction according to the second installation instruction, so that the battery changes from the first side facing up to the second side facing up, and then the battery 300 is installed again.

[0113] In an optional embodiment, the operating device can flip the battery 180 degrees along the first direction by holding the flipping device of the battery so that the upward side of the battery is the second side, and then the battery is installed on the electrical device.

[0114] Optionally, the battery may be flipped clockwise or counterclockwise along the first direction, which is not limited in this application.

[0115] In the above embodiment, the battery is flipped 180 degrees along the first direction according to the second installation information, so that the battery can be flipped from the first side facing up to the second side facing up, thereby realizing the alternating installation of the first side and the second side of the battery facing up, which is beneficial to solving the problem of insufficient electrolyte at the upper end of the electrode assembly in the battery and improving the safety of the battery.

[0116] According to some embodiments of the present application, optionally, the second installation information may indicate that the battery is flipped 180 degrees along the first direction after the battery was last disassembled.

[0117] That is, the second installation information may indicate that the battery should be flipped 180 degrees in the first direction immediately after the last removal of the battery so that the second side of the battery faces upward.

[0118] In this embodiment, the second installation information can be used to instruct the battery to flip 180 degrees in the first direction immediately after the last removal, so that the battery is flipped from the first side facing upward to the second side facing upward. This eliminates the need for flipping at other times, and allows the battery to be installed with the first and second sides facing upward alternately, which helps resolve the problem of insufficient electrolyte at the top of the electrode assembly within the battery and improves battery safety.

[0119] According to some embodiments of the present application, optionally, the second installation information may indicate that the battery should be flipped 180 degrees along the first direction before the battery is installed next time.

[0120] That is, the second installation information may instruct the battery to flip 180 degrees along the first direction only when the battery is about to be reinstalled, so that the battery is flipped from the first side facing upward to the second side facing upward. In this way, flipping is not required at other times, and the battery can be installed with the first and second sides facing upward alternately, which helps to solve the problem of insufficient electrolyte at the top of the electrode assembly in the battery, thereby improving battery safety.

[0121] Of course, the second installation information may indicate that the battery should be flipped 180 degrees along the first direction at any time before the battery is installed next time, for example, indicating that the battery should be flipped 180 degrees along the first direction after each battery charging is completed. This application does not limit this.

[0122] According to some embodiments of the present application, optionally, the method 200 may further include: determining the first direction according to the setting position of the same-polarity electrical interface of the battery.

[0123] It should be understood that a pair of electrical interfaces generally includes a positive electrical interface and a negative electrical interface. Within the battery, the positive electrical interface can be connected to the positive output terminal of a battery cell, and the negative electrical interface can be connected to the negative output terminal of a battery cell. Similarly, a battery-powered electrical device is also provided with a pair of electrical interfaces. When the battery is installed in the electrical device, the positive electrical interface on the electrical device can be electrically connected to the positive electrical interface of the battery, and the negative electrical interface on the electrical device can be electrically connected to the negative electrical interface of the battery, thereby enabling the battery to provide electrical energy to the electrical device.

[0124] In the embodiment of the present application, the battery is provided with at least one pair of electrical interfaces, which can realize electrical connection with the electrical equipment, thereby providing electrical energy to the electrical equipment.

[0125] In order for the battery to remain electrically connected to the electrical device after being flipped, it is necessary that after the battery is flipped 180 degrees in the first direction, the battery still has an electrical interface with the corresponding polarity at the location where it is electrically connected to the electrical device, so that the electrical device can function normally. Therefore, the first flip direction of the battery can be determined based on the location of the same-polarity electrical interface of the battery.

[0126] When the same-polarity electrical interfaces are symmetrically arranged on the wall of the battery housing along the centerline of the battery in a first direction, flipping the battery 180 degrees in the first direction allows the flipped battery to still have the corresponding polarity electrical interfaces at the location where it is electrically connected to the electrical device, thereby providing electrical energy to the electrical device through the electrical interfaces. In other words, the same-polarity electrical interfaces of the battery can be symmetrically arranged on the wall of the battery housing along any direction perpendicular to the direction of gravity Z of the battery. Before installing the battery, the battery can be flipped 180 degrees in this direction to still be able to normally electrically connect to the electrical device.

[0127] Optionally, the battery may be in any shape, such as a square battery, a rectangular battery, a cylindrical battery, etc.

[0128] In this embodiment, the first direction of battery flipping is determined based on the setting position of the same-polarity electrical interface of the battery, so that after the battery is flipped 180 degrees along the first direction, the battery still has an electrical interface of corresponding polarity at the position where it is electrically connected to the electrical device, so as to be electrically connected to the electrical device, thereby providing electrical energy to the electrical device.

[0129] According to some embodiments of the present application, optionally, determining the first direction based on the setting position of the battery's electrical interface may include: if the same-polarity electrical interfaces of the battery are symmetrically arranged on the wall of the battery box along the center line of the battery's length direction, the first direction is the length direction of the battery.

[0130] Alternatively, the battery 300 may be in the shape of a rectangular parallelepiped. Figures 4 to 6 illustrate one configuration of electrical interfaces in the battery 300. Alternatively, as shown in Figures 4 to 6, the battery 300 includes two pairs of electrical interfaces, namely a first pair of electrical interfaces 310 and a second pair of electrical interfaces 320. The first pair of electrical interfaces 310 and the second pair of electrical interfaces 320 may be disposed on two opposing surfaces of the battery 300, such as the first surface 301 and the second surface 302.

[0131] Optionally, the first pair of electrical interfaces 310 includes a first positive electrical interface 311 and a first negative electrical interface 312 , and the second pair of electrical interfaces 320 includes a second positive electrical interface 321 and a second negative electrical interface 322 .

[0132] As shown in Figure 6, the first positive electrical interface 311 and the second positive electrical interface 321 are symmetrically arranged on the wall of the battery 300 casing along the centerline CO1 of the battery 300's length direction X. The first negative electrical interface 312 and the second negative electrical interface 322 are symmetrically arranged on the wall of the battery 300 casing along the centerline CO1 of the battery 300's length direction X. Assuming that the battery 300 is currently installed on an electrical device with its first surface 301 facing upward, the electrical device has a pair of electrical interfaces at positions corresponding to the first pair of electrical interfaces 310. The battery 300 provides electrical energy to the electrical device through the first pair of electrical interfaces 310. When the battery 300 is rotated 180 degrees along the length direction X, the position of the second pair of electrical interfaces 320 of the battery 300 is flipped to the position of the first pair of electrical interfaces 310, allowing the second pair of electrical interfaces 320 to connect to the electrical interfaces of the electrical device, and the battery 300 can provide electrical energy to the electrical device through the second pair of electrical interfaces 320.

[0133] In this embodiment, when the electrical interfaces of the battery 300 with the same polarity are symmetrically arranged on the wall of the battery 300 along the center line CO1 in the longitudinal direction X, after the battery 300 is flipped 180 degrees along the longitudinal direction X, the battery 300 still has an electrical interface with the corresponding polarity at the position electrically connected to the electrical device, so as to be electrically connected to the electrical device, thereby providing electrical energy to the electrical device.

[0134] According to some embodiments of the present application, optionally, determining the first direction based on the setting position of the electrical interface of the battery may include: if the same-polarity electrical interfaces of the battery are symmetrically arranged on the wall of the battery box along the center line of the width direction of the battery, the first direction is the width direction of the battery.

[0135] Alternatively, the battery may be in the shape of a rectangular parallelepiped. Figures 4, 7, and 8 illustrate another arrangement of electrical interfaces in the battery 300. Alternatively, as shown in Figures 4, 7, and 8, the battery 300 includes two pairs of electrical interfaces, namely a first pair of electrical interfaces 310 and a second pair of electrical interfaces 320. The first pair of electrical interfaces 310 and the second pair of electrical interfaces 320 may be disposed on two opposing surfaces of the battery 300.

[0136] Optionally, the first pair of electrical interfaces 310 includes a first positive electrical interface 311 and a first negative electrical interface 312 , and the second pair of electrical interfaces 320 includes a second positive electrical interface 321 and a second negative electrical interface 322 .

[0137] As shown in Figure 8, the first positive electrical interface 311 and the second positive electrical interface 321 are symmetrically arranged on the wall of the battery 300 casing along the centerline CO2 in the width direction Y of the battery 300. The first negative electrical interface 312 and the second negative electrical interface 322 are symmetrically arranged on the wall of the battery 300 casing along the centerline CO2 in the width direction Y of the battery 300. Assuming that the battery 300 is currently installed on an electrical device with its first surface 301 facing upward, the electrical device has a corresponding pair of electrical interfaces at positions corresponding to the first pair of electrical interfaces 310. The battery 300 provides electrical energy to the electrical device through the first pair of electrical interfaces 310. When the battery 300 is rotated 180 degrees along the width direction Y, the position of the second pair of electrical interfaces 320 of the battery 300 is flipped to the position of the first pair of electrical interfaces 310, allowing the second pair of electrical interfaces 320 to connect to the electrical interfaces of the electrical device, and the battery 300 can provide electrical energy to the electrical device through the second pair of electrical interfaces 320.

[0138] In this embodiment, when the same-polarity electrical interfaces of the battery are symmetrically arranged on the wall of the battery 300 along the center line CO2 in the width direction Y, after the battery 300 is flipped 180 degrees in the width direction Y, the battery 300 still has an electrical interface of corresponding polarity at the position where it is electrically connected to the electrical device, so as to be electrically connected to the electrical device, thereby providing electrical energy to the electrical device.

[0139] It should be understood that Figures 4 to 8 are merely exemplary arrangements of the battery's electrical interfaces, and this application does not limit the number and arrangement positions of the battery's electrical interfaces.

[0140] In the above embodiments, flipping the battery before reinstalling it each time can effectively solve the problem of insufficient electrolyte at the upper end of the electrode assembly in the battery. However, the more times the battery is flipped, the more adverse effects it has on the mechanical strength and life of the operating device.

[0141] Based on this, according to some embodiments of the present application, optionally, method 200 further includes: obtaining battery status information, and the above step S220 may specifically be: generating second installation information according to the first installation information and the battery status information.

[0142] Optionally, the battery status information may include the discharge depth of the battery after the last flip, the sampled temperature of the battery cells in the battery, the number of fast charges of the battery after the last flip, the rest time of the battery after the last flip, and other information.

[0143] The depth of discharge (DOD) of a battery refers to the ratio of the battery's discharge volume to its nominal capacity. Fast charging involves high-power DC charging, typically exceeding 40 kW. The DC input voltage for fast charging is typically 380V. However, the output voltage varies across charging platforms, and currently ranges from 300 to 700V.

[0144] In one embodiment, the second installation information may be generated based on the first installation information only when the battery status information meets a specific condition, to instruct the battery to be installed next time with the second side facing upward.

[0145] The above embodiment can generate the second installation information when the battery status information meets specific conditions, and it does not need to be generated before each battery installation. In this way, there is no need to flip the battery before each battery installation, which can improve the mechanical strength and life of the operating device used to install or remove the battery.

[0146] According to some embodiments of the present application, optionally, generating the second installation information based on the first installation information and the battery status information may include: generating the second installation information when the cumulative depth of discharge of the battery after the last flip is greater than 200%.

[0147] The greater the depth of discharge of the battery, the easier it is for the electrolyte to volatilize, and the lower the concentration, the larger the range of electrolyte deficiency in the electrode assembly will be, and the more likely lithium plating will occur, thus affecting the safety of the battery.

[0148] Therefore, in the above embodiment, when the cumulative depth of discharge of the battery exceeds 200%, a second installation message is generated, so that the battery is installed again with the second side facing upward, opposite the first side that was facing upward during the previous installation or removal. This allows the electrolyte to evenly penetrate the entire electrode assembly, thereby solving the problem of lithium plating caused by excessive depth of discharge and improving battery safety. In addition, this eliminates the need to flip the battery before each reinstallation, which can improve the mechanical strength and life of the operating device.

[0149] Of course, the second installation information may also be generated when the cumulative depth of discharge of the battery is greater than other values, such as 300%. This value may be set as needed based on the safety requirements of the battery and the mechanical strength requirements of the operating device.

[0150] According to some embodiments of the present application, optionally, generating the second installation information based on the first installation information and the battery status information may include: generating the second installation information when the sampling temperature of the battery cell of the battery is greater than 40 degrees or less than 10 degrees.

[0151] The higher the sampling temperature of the battery cells within the battery, the more easily the electrolyte will volatilize. If the battery is left in one state for a long time, the upper end of the electrode assembly will remain in one state for a long time, which will increase the scope of electrolyte deficiency and make lithium precipitation more likely, further affecting battery safety. If the battery sampling temperature is too low, the electrolyte may form a nickel interlayer, resulting in an uneven electrolyte solution, affecting battery safety and performance.

[0152] In the above embodiment, when the temperature of a battery cell within the battery is greater than 40°C or less than 10°C, second installation information is generated to install the battery with the second side facing upward, opposite the first side that faced upward during the previous installation or removal. This allows the electrolyte to evenly penetrate the entire electrode assembly, thereby resolving the problem of uneven electrolyte solution caused by excessively high battery cell temperatures and improving battery safety. Furthermore, this eliminates the need to flip the battery before each reinstallation, thereby improving the mechanical strength and lifespan of the operating device.

[0153] Of course, the second installation information may also be generated when the temperature of the battery cell in the battery is in another range, such as greater than 50 degrees. The temperature range may be set as needed based on the safety requirements of the battery and the mechanical strength requirements of the device for installing the battery.

[0154] According to some embodiments of the present application, optionally, generating the second installation information based on the first installation information and the battery status information may include: generating the second installation information when the number of fast charges of the battery reaches 2 times after the last flip.

[0155] When the battery is fast charged, excessive current and voltage will cause the battery to heat up, thereby reducing the internal electrolyte. At this time, if the battery is left in one state for a long time, the range of insufficient electrolyte in the electrode assembly will become larger, and lithium plating will be more likely to occur, further affecting the safety of the battery.

[0156] In the above embodiment, when the battery has been fast-charged twice, second installation information is generated, so that the battery can be installed again with the second side facing up, opposite the first side that was facing up during the previous installation or removal. This allows the electrolyte to evenly penetrate the entire electrode assembly, thereby resolving the problem of lithium deposition caused by excessive fast charging and improving battery safety. Furthermore, this eliminates the need to flip the battery before each reinstallation, which can improve the mechanical strength and lifespan of the operating device.

[0157] Of course, the second installation information can also be generated when the number of fast charging times of the battery reaches other times, such as 4 times. The number of times can be set as needed based on the safety requirements of the battery and the mechanical strength requirements of the device for installing the battery.

[0158] According to some embodiments of the present application, optionally, generating the second installation information based on the first installation information and the battery status information may include: generating the second installation information when the battery has been stationary for more than 500 hours since its last flip.

[0159] When batteries are left idle for too long, gravity can cause insufficient electrolyte at the top of the electrode assembly, leading to insufficient wetting and causing electrolyte bridge failure, which can lead to severe lithium deposition. Testing has shown that when batteries are left idle for more than 500 hours, purple or circular spots will begin to appear on the top of the electrode assembly, indicating lithium deposition points.

[0160] In the above embodiment, when the battery has been inactive for more than 500 hours since its last flip, second installation information is generated, urging the battery to be installed again with the second side facing upward, opposite the first side that faced upward during the previous installation or removal. This allows the electrolyte to evenly penetrate the entire electrode assembly, thereby resolving the problem of lithium deposition caused by prolonged battery inactivity and improving battery safety. Furthermore, this eliminates the need to flip the battery before each reinstallation, thereby improving the mechanical strength and lifespan of the operating device.

[0161] Of course, the second installation information may be generated only when the battery's standing time is greater than other values, for example, 600 hours. This value may be set as needed based on the battery's safety and the mechanical strength requirements of the device for installing the battery.

[0162] According to some embodiments of the present application, optionally, method 200 may further include: sending second installation information.

[0163] Accordingly, in one embodiment, the operating device may receive the second installation information and may operate the battery according to the second installation information.

[0164] By sending the second installation information, the operating device that performs installation or removal of the battery can be instructed to install the battery with the second side facing up for the next installation, thereby realizing alternating installation with the first and second sides of the battery facing up, which is beneficial to solving the problem of insufficient electrolyte at the upper end of the electrode assembly in the battery, thereby improving the safety of the battery.

[0165] FIG9 illustrates another method 400 for installing a battery provided herein. The method may be performed by an operating device, such as the aforementioned device specifically for installing or removing a battery. As shown in FIG9 , the method 400 includes at least some of the following:

[0166] S410, obtaining second installation information of the battery, where the second installation information is used to instruct the second side of the battery to face upward for the next installation, wherein the second side is the side opposite to the first side of the battery, and the first side is the side that faced upward when the battery was last installed or removed.

[0167] S420: Operate the battery according to the second installation information.

[0168] In an optional embodiment, the operating device may actively obtain the second installation information, and then operate the battery according to the second installation information, so that the battery is installed with the second surface facing upward.

[0169] In another optional embodiment, the operating device may receive the second installation information, and then operate the battery according to the second installation information, so that the battery is installed with the second surface facing upward.

[0170] In an embodiment of the present application, the battery can be installed for the next time with the second side facing upward, which is opposite to the first side facing upward during the previous installation or removal, according to the second installation information. This allows the first side and the second side of the battery to be installed alternately facing upward, which is beneficial to solving the problem of insufficient electrolyte at the upper end of the electrode assembly in the battery, thereby improving the safety of the battery.

[0171] According to some embodiments of the present application, optionally, when the first surface is facing upward, the second installation information indicates that the battery should be flipped 180 degrees along a first direction, where the first direction is perpendicular to the direction of gravity.

[0172] In an embodiment of the present application, the battery is flipped 180 degrees along the first direction according to the second installation information, so that the battery can be flipped from the first side facing up to the second side facing up, thereby realizing the alternating installation of the first side and the second side of the battery facing up, which is beneficial to solving the problem of insufficient electrolyte at the upper end of the electrode assembly in the battery, thereby improving the safety of the battery.

[0173] According to some embodiments of the present application, optionally, the above step S420 may include: after the battery is last disassembled, turning the battery 180 degrees along the first direction.

[0174] In this embodiment, based on the second installation information, the battery can be flipped 180 degrees in the first direction immediately after the last removal, so that the battery is flipped from the first side facing upward to the second side facing upward. This eliminates the need for further flipping and allows the battery to be installed in the electrical device with the first and second sides alternately facing upward, thereby resolving the problem of insufficient electrolyte at the top of the electrode assembly within the battery and improving battery safety.

[0175] According to some embodiments of the present application, optionally, the above step S420 may include: before the battery is installed for the next time, turning the battery 180 degrees along the first direction.

[0176] In this embodiment, based on the second installation information, the battery can be flipped 180 degrees along the first direction just before reinstallation, so that the battery is flipped from the first side facing upward to the second side facing upward. This allows the battery to be flipped only before the next installation and not at other times. Furthermore, the battery can be installed in electrical equipment with the first and second sides alternately facing upward, which helps resolve the problem of insufficient electrolyte at the top of the battery's electrode assembly and improves battery safety.
