Description

A battery for a vehicle Technical Field

[0001] This specification relates to the field of battery technology, and in particular to a battery for a vehicle. Background Art

[0002] With the advancement of technology, a wide variety of mobility vehicles have emerged, bringing significant convenience to people's lives. In particular, the use of short-distance mobility vehicles, such as scooters, tricycles, and self-balancing scooters, is increasing. Some common mobility vehicles often incorporate batteries to power them or add auxiliary functions, such as timing, pedometers, heart rate monitoring, and weather forecasts.

[0003] Currently, commuter vehicles use either a fixed battery system, where the battery is integrated into the vehicle. Another approach uses a battery swap system, where the battery is removably mounted on the vehicle. However, with the battery swap system, a single battery model can only be used in a single vehicle model, resulting in poor versatility and high cost.

[0031] The following description provides specific application scenarios and requirements for this specification, with the goal of enabling those skilled in the art to make and use the contents of this specification. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but is intended to be accorded the broadest scope consistent with the claims.

[0032] The terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. For example, as used herein, the singular forms "a," "an," and "the" may also include the plural forms unless the context clearly indicates otherwise. When used in this specification, the terms "comprise," "include," and / or "contain" are intended to refer to the presence of the associated integers, steps, operations, elements, and / or components, but do not preclude the presence of one or more other features, integers, steps, operations, elements, components, and / or groups or the addition of other features, integers, steps, operations, elements, components, and / or groups in the system / method.

[0033] In this application, "X includes at least one of A, B, or C" means that X includes at least A, or X includes at least B, or X includes at least C. In other words, X may include only any combination of A, B, and C, or may include any combination of A, B, and C as well as other possible contents / elements. The arbitrary combination of A, B, and C may be A, B, C, AB, AC, BC, or ABC.

[0034] In this application, unless explicitly stated otherwise, the association relationship between structures can be a direct association relationship or an indirect association relationship. For example, when describing "A is connected to B", unless it is explicitly stated that A is directly connected to B, it should be understood that A can be directly connected to B or indirectly connected to B; for another example, when describing "A is above B", unless it is explicitly stated that A is directly above B (AB are adjacent and A is above B), it should be understood that A can be directly above B or indirectly above B (AB is separated by other elements and A is above B). And so on.

[0035] These and other features of this specification, as well as the operation and function of the associated elements of the structure, and the economical assembly and manufacture of the components, can be significantly improved with consideration of the following description. Reference is made to the accompanying drawings, all of which form a part of this specification. However, it should be expressly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0036] In a battery-swap vehicle, the compatibility of the battery with the vehicle and / or charging device depends on the compatibility of the battery interface with the vehicle and / or charging device. In existing technologies, batteries typically have a single battery interface, which makes them less versatile. They can only connect to a single vehicle and / or charging device compatible with the battery interface, and cannot connect to other vehicles and / or charging devices that do not match that battery interface. This also makes it impossible to meet the charging needs of different scenarios.

[0037] Figure 1 shows a schematic diagram of the assembly of a battery compartment 1000, a mobility vehicle 001, and a charging device 002 according to some exemplary embodiments of the present application. As shown in Figure 1 , some embodiments of the present application provide a vehicle battery 2000 that is adaptable to different types of mobility vehicles 001 and / or charging devices 002.

[0038] The vehicle for walking 001 can be any means of transportation used for short-distance travel, commuting, or leisure and entertainment. For example, the vehicle for walking 001 can be an electric bicycle, which combines the riding method of a traditional bicycle with an electric auxiliary system, and the rider can move forward by pedaling manually or by battery power. For example, the vehicle for walking 001 can be an electric scooter, which is powered by electricity, and some models can be folded and carried. For example, the vehicle for walking 001 can be an electric balance car, which is provided with two parallel wheels, powered by a battery, and has a built-in balance control system so that the rider can ride while standing. For another example, the vehicle for walking 001 can be an electric four-wheeled scooter, which has a stable four-wheel structure, powered by a battery, and the user can sit on the seat and travel smoothly. It should be noted that those skilled in the art should understand that other vehicles for walking 001 are also within the scope of protection of this specification.

[0039] The charging device 002 can be any device capable of replenishing the battery. For example, the charging device 002 can be a portable charger that can be installed on the vehicle to replenish the battery at any time. For example, the charging device 002 can be a fixed charging device installed in a charging area, where the battery can be replenished after being removed from the mobility vehicle 001. This specification does not limit the type of charging device 002.

[0040] The mobility scooter 001 and / or the charging device 002 may include a battery compartment 1000. The battery compartment 1000 may be a mounting base for the battery 2000. The battery compartment 1000 may be a thin-walled shell structure with a hollow interior. The battery 2000 may be installed inside the battery compartment 1000. The battery compartment 1000 may be of any ergonomic shape, such as a rectangular parallelepiped, a cube, a cylinder, or a combination thereof. The following content is described using the battery compartment 1000 as a rectangular parallelepiped as an example. The material of the battery compartment 1000 may be any material, such as aluminum alloy, magnesium alloy, stainless steel, carbon fiber composite material, and the like. This specification does not limit the shape and material of the battery compartment 1000.

[0041] FIG2 shows a schematic diagram of the installation of a battery compartment 1000 and a battery 2000 according to some exemplary embodiments of the present application. As shown in FIG1 and FIG2 , in some embodiments, the battery compartment 1000 may include a main compartment body 110 and a compartment cover 130. The main compartment body 110 and the compartment cover 130 are thin-walled parts. The main compartment body 110 and the compartment cover 130 are installed together to form a hollow shell structure, which contains a storage compartment 150. The storage compartment 150 can accommodate the battery 2000 to protect and prevent dust from entering the battery 2000. The main compartment body 110 and the compartment cover 130 can be connected by a detachable connection to facilitate replacement of the battery 2000. The detachable connection can be a snap connection, a hinge connection, etc. This specification is not limited to this. In some embodiments, the battery compartment 1000 can also be assembled by two or more shells, which is not described in detail in this specification.

[0042] When the battery compartment 1000 is a rectangular parallelepiped, the main compartment body 110 includes a bottom surface 111 and four side walls 113. The bottom surface 111 and the four side walls 113 are located on the side of the main compartment body 110 close to the storage compartment 150. The bottom surface 111 is arranged opposite to each other and intersects with the side walls 113 and the compartment cover 130 respectively. At least one peripheral interface is fixedly provided on the main compartment body 110. Specifically, the peripheral interface is fixedly provided on the bottom surface 111 and / or the side walls 113. There are many ways to set up the peripheral interface. For example, the peripheral interface can be provided on the bottom surface 111; the peripheral interface can also be provided on the side walls 113; or when the main compartment body includes multiple peripheral interfaces, the multiple peripheral interfaces can also be provided on the bottom surface 111 and the side walls 113 respectively. Each peripheral interface can be compatible with the battery 2000. These peripheral interfaces have the same functions and can both transmit power and communicate data. The at least one peripheral interface may be any number, such as 1, 2, 3, 4, etc. Those skilled in the art should know that the locations of other peripheral interfaces are also within the scope of protection of this specification.

[0043] In some embodiments, the battery compartment 1000 includes a first peripheral interface 115. When the battery 2000 is inserted into the battery compartment 1000, the first peripheral interface 115 couples with the battery 2000 to complete power transmission. In some embodiments, the battery compartment 1000 includes a second peripheral interface 117. When the battery 2000 is inserted into the battery compartment 1000, the second peripheral interface 117 couples with the battery 2000 to complete power transmission. This allows the battery 2000 to be compatible with various types of electric scooters or charging devices with different interfaces.

[0044] Figure 3 shows a schematic structural diagram of a battery 2000 for a vehicle provided in this specification from a first perspective. As shown in Figure 3, this specification provides a battery 2000 for a vehicle. The battery 2000 is the main power source of the mobility vehicle 001, and can store electrical energy and convert it into mechanical energy when the electric vehicle is running, thereby driving the mobility vehicle 001 to move. The battery 2000 can be installed on the mobility vehicle 001 and / or the charging device 002. Specifically, the battery 2000 can be adapted to the above-mentioned storage compartment 150. When the battery 2000 is installed with the mobility vehicle 001 and / or the charging device 002, the battery 2000 is installed in the storage compartment 150 of the above-mentioned battery compartment 1000. The adaptation can be adaptation in shape and size. The type of the battery 2000 can be at least one of a lead-acid battery, a lithium-ion battery, a lithium iron phosphate battery or a nickel-metal hydride battery.

[0045] In Figure 3, the battery 2000 includes an interface unit 210, a power supply unit 230, an operating unit 250, and a control circuit (not shown). The power supply unit 230 stores energy through chemical reactions and converts chemical energy into electrical energy during the operation of the battery 2000. The interface unit 210 can transmit the electrical energy of the power supply unit 230 to other electrical components of the mobility vehicle 001 or connect to the charging device 002 for electrical energy replenishment. The operating unit 250 can display the status of the battery 2000 and can also control the opening and closing of the battery 2000, thereby improving the user experience. The control circuit can receive control commands from the operating unit 250 and can also transmit status information of the battery 2000 to the operating unit 250. The normal operation of the battery 2000 is achieved through the mutual cooperation of the interface unit 210, the power supply unit 230, the operating unit 250, and the control circuit.

[0046] Furthermore, the power supply unit 230 and the control circuit are first electrically connected, and the control circuit is then electrically connected to the operating unit 250 and the interface unit 210, respectively. The interface unit 210 is then electrically connected to the mobility vehicle 001 and / or the charging device 002, thereby completing the monitoring of the battery 2000 status, controlling the battery 2000 to be turned on and off, and transmitting data between the battery 2000 and the mobility vehicle 001 and / or the charging device 002. On the one hand, the control circuit can monitor the status of the power supply unit 230 in real time and output appropriate control signals to the operating unit 250 based on the monitoring data. The operating unit 250 receives this control signal and displays it. On the other hand, the operating unit 250 can connect or close the circuit between the control circuit and the interface unit 210, thereby controlling the flow of current from the power supply unit 230 to other electrical components or prohibiting the flow of current from the power supply unit 230 to other electrical components. On the other hand, the power supply unit 230 can transmit power and communicate with the mobility vehicle 001 and / or the charging device 002 through the control circuit and the interface unit 210 .

[0047] The control circuit can be installed inside the battery 2000, for example, inside the interface unit 210 or the operating unit 250. The control circuit includes multiple ports, through which the control circuit can connect to the power supply unit 230, the operating unit 250, and the interface unit 210. The multiple ports may include a battery connection port, a communication port, a switch control port, an indicator light port, and the like. As described above, electrical connections between the power supply unit 230, the control circuit, the operating unit 250, and the interface unit 210 can be made through the multiple ports described above.

[0048] Specifically, the control circuit can be electrically connected to the power supply unit 230 through the battery connection port. The battery connection port may include a positive connection terminal and a negative connection terminal. The positive connection terminal of the battery connection port is connected to the positive power output of the power supply unit 230, and the negative connection terminal is connected to the negative power output of the power supply unit 230, so as to realize the monitoring of the status of the power supply unit 230. Specifically, the control circuit can monitor various status parameters of the power supply unit 230 through the positive connection terminal and the negative connection terminal, such as battery voltage, power state, charging state, discharging state, etc. Those skilled in the art should understand that monitoring of other status parameters is also within the scope of protection of this specification.

[0049] The control circuit can be electrically connected to the operating unit 250 via the indicator port and the switch control port. Specifically, the indicator port is electrically connected to the display component of the operating unit 250 to display the status of the battery 2000. The indicator port can transmit the status parameters of the power supply unit 230 monitored by the control circuit to the display component of the operating unit 250. The switch control port is electrically connected to the switch control component of the operating unit 250 to control the opening and closing of the battery 2000.

[0050] The control circuit can be electrically connected to the interface unit 210 through the communication port, the ground authentication hard wire detection port, and the charging wake-up port. The communication port can be electrically connected to the interface unit 210 so that the power supply unit 230 can exchange data with the mobility vehicle 001 and / or the charging device 002 through the interface unit 210. Specifically, the control circuit can use multiple communication ports to exchange data and transmit control instructions with the mobility vehicle 001 and / or the charging device 002. The multiple communication ports can be CAN (Controller Area Network) communication ports, I 2 One of the following communication ports: C (Inter-Integrated Circuit) communication port, SPI (Serial Peripheral Interface) communication port, UART (Universal Asynchronous Receiver-Transmitter) communication port, or LIN (Local Interconnect Network) communication port.

[0051] The ground authentication hard-wire detection port can be electrically connected to the interface portion 210. On the one hand, when the battery 2000 is connected to the vehicle for walking 001 and / or the charging device 002, the ground authentication hard-wire detection port can provide a specific safety authentication mechanism. In this mechanism, the ground authentication hard-wire detection port of the control circuit can be used to check the identity authentication between the battery 2000 and the vehicle for walking 001 and / or the charging device 002. Only the verified vehicle for walking 001 and / or the charging device 002 can access the battery 2000 and perform data exchange with the battery 2000. On the other hand, the ground authentication hard-wire detection port can be used to detect whether the battery 2000 is well grounded to ensure electrical safety. When the ground is poor or disconnected, the control circuit can quickly detect and take corresponding protective measures, such as stopping charging or discharging operations, to avoid potential safety hazards.

[0052] The charging wake-up port can be electrically connected to the interface unit 210. In certain scenarios, the control circuit can control the battery 2000 to execute a wake-up procedure through the charging wake-up port. For example, in a battery 2000 that has not been used for a long time, the control circuit can periodically perform a charging wake-up through the charging wake-up port to maintain the activity of the battery 2000. For example, when the battery 2000 is connected to the mobility vehicle 001 and / or the charging device 002, the mobility vehicle 001 and / or the charging device 002 will send a charging signal through the charging wake-up port. The control circuit detects the charging signal and initiates the charging procedure. For example, when the battery 2000 is connected to the mobility vehicle 001 and / or the charging device 002, the control circuit detects a change in the battery 2000 state and pulls the DET (Detection) signal low as a notification signal of the state change. At this time, the battery 2000 executes the charging wake-up procedure. For another example, when the battery 2000 is connected to the mobility vehicle 001, the battery 2000 outputs a preset output voltage through the control circuit. After a preset duration, the control circuit reduces the output voltage to 0, thereby actively waking up the battery for charging. Those skilled in the art should understand that other charging wake-up scenarios are also within the scope of protection of this specification.

[0053] The interface portion 210, power supply portion 230, and operating portion 250 connected to the control circuit can be integrally formed, or they can be formed separately as independent units and then assembled together to form the battery 2000. When the interface portion 210, power supply portion 230, and operating portion 250 are formed separately as independent units and then assembled to form the battery 2000, the power supply portion 230 serves as a mounting base for the other components. Specifically, the power supply portion 230 includes a first end 235 and a second end 237. The interface portion 210 is mounted on the first end 235 of the power supply portion 230. The mounting method can be a fixed connection or a detachable connection. The operating portion 250 is mounted on the second end 237 of the power supply portion 230, and the mounting method can be a fixed connection or a detachable connection. Furthermore, the fixed connection can be a threaded connection, welding, riveting, bonding, a snap connection, a mortise and tenon connection, etc. The detachable connection can be a snap connection, a hinge connection, a key connection, etc. This specification does not limit this.

[0054] Figure 4 shows a schematic structural diagram of the power supply unit 230 of the battery 2000 provided according to some embodiments of this specification. As shown in Figure 4, the power supply unit 230 may be the main energy storage component of the battery 2000. The power supply unit 230 may include a first shell 231 and a battery body 233. The first shell 231 may be a mounting base for the battery body 233, which supports the battery body 233. The battery body 233 is at least partially fixedly mounted inside the first shell 231. The first shell 231 may be adapted to the above-mentioned battery compartment 1000, and the adaptation may be adaptation in shape and size. The material of the first shell 231 may be stainless steel, aluminum, hard plastic, etc. This specification does not limit the shape and material of the first shell 231.

[0055] The battery body 233 includes at least one battery cell. The at least one may be 1, 2, 3, 4, 6, etc., and is not limited here. When the number of battery cells is multiple, in some embodiments, the multiple battery cells are connected in series via internal conductors to form the battery body 233. For example, if the target battery body 233 has a voltage of 48V and a current of 40A, then four battery cells with a voltage of 12V and a current of 40A can be selected and connected in series. In some embodiments, the multiple battery cells are connected in parallel via internal conductors to form the battery body 233. For example, if the target battery body 233 has a voltage of 48V and a current of 40A, then four battery cells with a voltage of 48V and a current of 10A can be selected and connected in parallel. The positive and negative poles of the battery power output are located on the first shell 231 and face the side of the interface portion 210.

[0056] The interface unit 210 is the port through which the power supply unit 230 outputs power. The power supply unit 230's power and status can be output through the interface unit 210. Specifically, at least a portion of the interface unit 210 is electrically connected to the battery body 233 of the power supply unit 230, and at least a portion of the interface unit 210 is electrically connected to the control circuit. When the battery 2000 is connected to the mobility vehicle 001 and / or charging device 002, the battery body 233 and the control circuit are electrically connected to the battery compartment 1000 of the mobility vehicle 001 and / or charging device 002 through the interface unit 210 to exchange data and transmit commands.

[0057] Figure 5 illustrates a schematic structural diagram of the interface portion 210 of the battery 2000 described in Figure 3 of this specification; Figure 6 illustrates a right side view of the battery 2000 provided in accordance with some embodiments of this specification; and Figure 7 illustrates a top view of the battery 2000 provided in accordance with some embodiments of this specification. As shown in Figures 5-7, the interface portion 210 includes a second housing 211, a first battery interface 213, a second battery interface 215, a first interface surface 217, a second interface surface 218, and a recessed space 219. The second housing 211 may serve as a mounting base for the interface portion 210, providing support. Other components of the interface portion 210 may be mounted on the second housing 211, such as the first battery interface 213, the second battery interface 215, the first interface surface 217, the second interface surface 218, and the recessed space 219. The second housing 211 may be integrally formed with the first housing 231, or may be formed separately and then assembled. When the second shell 211 and the first shell 231 are separately molded and then assembled, the second shell 211 can be connected to the first shell 231. Specifically, the second shell 211 can be fixedly connected to the first shell 231 or detachably connected. The fixed connection and detachable connection methods are the same as those described above and are not described here. The material of the second shell 211 can be stainless steel, aluminum, hard plastic, etc. This specification does not limit the shape and material of the second shell 211.

[0058] The first interface surface 217 is provided on the second shell 211 and is located on the end surface of the interface portion 210 away from the power supply portion 230. When the battery 2000 is installed in the battery compartment 1000, the position of the first interface surface 217 corresponds to the position of the bottom surface 111 of the battery compartment 1000. The first battery interface 213 is installed on the first interface surface 217 and is adapted to the first peripheral interface 115. When the battery 2000 is inserted into the battery compartment 1000, the first battery interface 213 provided on the first interface surface 217 is coupled with the first peripheral interface 115 provided on the bottom surface 111 of the battery compartment 1000 and completes the electrical connection. The adaptation can be adaptation in shape and size.

[0059] The first battery interface 213 includes a base 2131, which provides a mounting carrier for other parts of the first battery interface 213. The base 2131 includes a contact area 2131-1 and a first protective wall 2131-3. The first protective wall 2131-3 is adapted to the contact area 2131-1 and is arranged around the contact area 2131-1. The adaptation can be adaptation in shape and size. Among them, a plurality of contacts are distributed on the contact area 2131-1. The plurality of contacts are raised conductors with a first height. The first protective wall 2131-3 has a second height. The second height is greater than the first height, thereby forming protection for the plurality of contacts in the contact area 2131-1 from the side and front of the contact area 2131-1. The material of the plurality of contacts can be a metal alloy, such as a copper alloy or other material with good conductivity. This specification does not limit the material of the contacts.

[0060] The presence of multiple contacts can enable the battery 2000 to achieve circuit connectivity with the mobility vehicle 001 and / or the charging device 002. The multiple contacts include at least one communication contact array and at least one power contact array. The at least one communication contact array can enable communication between the battery 2000 and the mobility vehicle 001 and / or a third-party communication device. The at least one power contact array can enable the output of electrical energy from the battery 2000 and the input of electrical energy from the charging device 002. It should be noted that the at least one communication contact array can include one communication contact array, two communication contact arrays, three communication contact arrays, and so on. The at least one power contact array can include one power contact array, two power contact arrays, three power contact arrays, and so on.

[0061] For ease of illustration, the following description uses the example of a first battery interface 213 including one power contact array and two communication contact arrays. In this case, the two communication contact arrays are located on either side of the power contact array. Those skilled in the art will appreciate that other numbers of power contact arrays and communication contact arrays are also within the scope of this specification.

[0062] The power contact array is electrically connected to the battery body 233 and includes two first negative contacts 2133-1 and one first positive contact 2133-3. The two first negative contacts 2133-1 are each electrically connected to the negative power output terminal of the battery body 233, while the first positive contact 2133-3 is electrically connected to the positive power output terminal. The first positive contact 2133-3 is located between the two first negative contacts 2133-1. When the battery 2000 is connected to the mobility vehicle 001 and / or the charging device 002, one of the two first negative contacts 2133-1 communicates with the battery body 233 and, together with the first positive contact 2133-3, completes the circuit. The other first negative contact 2133-1 serves as a backup connection, preventing poor contact or damage to the first negative contact 2133-1 and increasing connection reliability.

[0063] The at least one communication contact array is electrically connected to the control circuit. Specifically, as described above, taking two communication contact arrays as an example, the two communication contact arrays are distributed on either side of a power contact array. When the battery 2000 is electrically connected to the mobility vehicle 001 and / or the charging device 002, the two communication contact arrays can be used differently in different scenarios. For example, one of the two communication contact arrays can be used for communication transmission, while the other serves as a backup. If one communication contact array fails, the other communication contact array can continue to transmit data, maintaining the stability of data transmission. For another example, when the battery 2000 needs to process a large amount of data, the two communication contact arrays can share the load, each responsible for different data streams. This can avoid data saturation caused by a single communication contact array, which would affect data transmission efficiency and response speed. For another example, when the mobility vehicle 001 and / or the charging device 002 are upgraded or new features are added, one of the two communication contact arrays can be assigned new communication tasks or support new communication protocols as needed. When the number of communication contact arrays is other, the functions and usage scenarios of the multiple communication contact arrays are the same as described above and are not further described here.

[0064] Each of the two communication contact arrays includes four contacts. The four contacts can be used for data transmission, security protection, and charging wake-up, respectively. Specifically, the four contacts include a first contact 2135-1, a second contact 2135-3, a third contact 2135-5, and a fourth contact 2135-7. Among them, the first contact 2135-1 and the second contact 2135-3 are electrically connected to the CAN communication port of the control circuit. Specifically, the first contact 2135-1 is electrically connected to the CAN communication H port of the control circuit, and the second contact 2135-3 is electrically connected to the CAN communication L port of the control circuit. The battery 2000 is connected to the mobility vehicle 001 and / or the charging device 002 through the first contact 2135-1 and the second contact 2135-3. Each node on the CAN bus interprets data and communicates by detecting the voltage difference between the CAN communication H port and the CAN communication L port. Among them, the first contact 2135-1 and the second contact 2135-3 can feed back the battery 2000 status information, control instructions and configuration data, fault diagnosis information, system synchronization and coordination information monitored by the control circuit to the replacement vehicle 001 and / or the charging device 002, and receive control instructions and configuration information from the replacement vehicle 001 and / or the charging device 002.

[0065] Third contact 2135-5 is electrically connected to the control circuit's ground authentication hardwire detection port. As described above, third contact 2135-5 functions as an authentication contact, verifying the identity of the mobility vehicle 001 and / or charging device 002 connected to battery 2000. Only authenticated mobility vehicles 001 and / or charging devices 002 can access and exchange data with battery 2000. Furthermore, third contact 2135-5 functions as a ground monitoring contact, detecting whether battery 2000 is properly grounded to ensure electrical safety.

[0066] The fourth contact 2135-7 is electrically connected to the charging wake-up port in the control circuit. When the battery 2000 is connected to the mobility vehicle 001 and the battery 2000 is low on power, the mobility vehicle 001 sends a charging signal to the fourth contact 2135-7. The fourth contact 2135-7 transmits the charging signal to the control circuit, which detects the charging signal and initiates the charging process. When the battery 2000 is connected to the mobility vehicle 001, the control circuit first outputs an output voltage of a preset voltage value through the fourth contact 2135-7. After a preset duration, the control circuit reduces the output voltage to 0 through the fourth contact 2135-7, thereby actively waking up the battery for charging. When the battery 2000 is connected to the charging device 002, the control circuit detects a change in the battery 2000 state through the fourth contact 2135-7, pulls the DET pin of the battery 2000 low, and initiates the charging process. Those skilled in the art will appreciate that other charging wake-up scenarios are also within the scope of this specification.

[0067] As described above, in addition to the first battery interface 213, the interface portion 210 also includes a second set of battery interfaces to provide a connection method for the battery 2000 that is different from the first battery interface 213. This second set of battery interfaces includes a second battery interface 215, a second interface surface 218, at least one side surface 216, and a recessed space 219. The recessed space 219 is provided on the second housing 211. The at least one side surface 216 is at least one of the four side surfaces that intersect with the end surface of the interface portion 210 facing away from the power supply portion 230. The recessed space 219 is formed by any two intersecting side surfaces of the four side surfaces. The second interface surface 218 is located within the recessed space 219. The second battery interface 215 is mounted on the second interface surface 218. As a second solution for charging and discharging the battery 2000, the second battery interface 215 is compatible with the second peripheral interface 117. The second battery interface 215 is coupled to the second peripheral interface 117 and electrically connected. The adaptation can be in terms of shape and size.

[0068] Specifically, at least one side surface 216 includes a first side surface 2161 and a second side surface 2163. The first side surface 2161 and the second side surface 2163 intersect and form a recessed space 219. The recessed space 219 includes a second interface surface 218. The recessed space 219 includes a first opening 2191 and a second opening 2193. The first opening 2191 is opened on the first side surface 2161 and is arranged opposite to the second interface surface 218, and the second opening 2193 is opened on the second side surface 2163. When the second battery interface 215215 is connected to the second peripheral interface 117, the second peripheral interface 117 enters the recessed space 219 from the first opening 2191 and couples with the second battery interface 215 located on the second interface surface 218, while the second opening 2193 allows the wires of the second peripheral interface 117 to enter the recessed space 219.

[0069] The recessed space 219 further includes a second protective wall 2195 , which extends from the first side surface 2161 to the second interface surface 218 and surrounds the second interface surface 218 . The second protective wall 2195 protects the second battery interface 215 from the side of the second interface surface 218 .

[0070] The second battery interface 215 is different in form from the first battery interface 213 described above but has the same function, and can realize the charging and discharging of the battery 2000 and the communication transmission between the battery 2000 and the third-party device. The second battery interface 215 includes at least one communication contact array and at least one power contact array. The at least one communication contact array can realize the communication between the battery 2000 and the mobility vehicle 001 and / or the third-party communication device. The at least one power contact array can realize the output of electrical energy from the battery 2000 and the input of electrical energy from the charging device 002. It should be noted that the at least one communication contact array may include one communication contact array, two communication contact arrays, three communication contact arrays, and so on. The at least one power contact array may include one power contact array, two power contact arrays, three power contact arrays, and so on. Figure 6 shows a schematic diagram of the structure of the second battery interface provided according to some embodiments of this specification. For ease of presentation, the following description takes the example of the second battery interface 215 including one power contact array and one communication contact array. At this time, a communication contact array is set on one side of the power contact array. Those skilled in the art should understand that other numbers of power contact arrays and communication contact arrays are also within the protection scope of this specification.

[0071] The at least one power contact array is electrically connected to the battery body 233. Specifically, as described above, taking one power contact array as an example, one power contact array includes one second negative contact 2151-1 and one second positive contact 2151-3. The one second negative contact 2151-1 is electrically connected to the negative power output terminal of the battery body 233, and the second positive contact 2151-3 is electrically connected to the positive power output terminal.

[0072] The at least one communication contact array is electrically connected to the control circuit. Specifically, as described above, taking a communication contact array as an example, a communication contact array is distributed on one side of a power contact array. A communication contact array includes four contacts. The four contacts can respectively perform data transmission, security protection, and charging wake-up. Specifically, the four contacts include a fifth contact 2153-1, a sixth contact 2153-3, a seventh contact 2153-5, and an eighth contact 2153-7. Among them, the fifth contact 2153-1 is electrically connected to the CAN communication H port of the control circuit, the sixth contact 2153-3 is electrically connected to the CAN communication L port of the control circuit, the seventh contact 2153-5 is electrically connected to the ground authentication hard-line detection port of the control circuit, and the eighth contact 2153-7 is electrically connected to the charging wake-up port in the control circuit. The fifth contact 2153-1, the sixth contact 2153-3, the seventh contact 2153-5, and the eighth contact 2153-7 have the same functions and connection relationships as the first contact 2135-1, the second contact 2135-3, the third contact 2135-5, and the fourth contact 2135-7, respectively, and are not further described here.

[0073] In addition, the battery 2000 also includes a guide device 270. When the first battery interface 213 is coupled to the first peripheral interface 115, the guide device 270 can guide the first battery interface 213. The guide device 270 can be of various types. For example, in some embodiments, either the battery 2000 or the battery compartment 1000 includes a linear bearing, and the other includes a guide rail. The linear motion guidance is achieved through the cooperation of the linear bearing and the guide rail. In some embodiments, either the battery 2000 or the battery compartment 1000 includes a guide post, and the other includes a guide sleeve. The cooperation of the guide post and the guide sleeve enables the movement of the battery 2000 along a preset path. In some embodiments, either the battery 2000 or the battery compartment 1000 includes a dovetail groove, and the other includes a T-slot. The cooperation between the dovetail groove and the T-slot enables the horizontal and vertical positioning and guidance of the battery 2000, and so on. It should be understood by those skilled in the art that other types of guide devices 270 are also within the scope of protection of this specification.

[0074] The interface portion 210 also includes a second battery interface cover 220. When the battery 2000 is closed, the second battery interface cover 220 covers the first opening 2191 and the second opening 2193, preventing moisture, dust, or other impurities from entering and affecting the performance of the second battery interface 215. The second battery interface cover 220 is movably connected to the second interface surface 218 or the second protective wall 2195. This movably connected connection can be a snap-fit ​​connection, a magnetic connection, a spring connection, a hinge connection, etc. This is not limited to this comparison in this specification.

[0075] The operating unit 250 facilitates user installation and removal of the battery 2000. Figure 7 shows a schematic structural diagram of the operating unit 250 for a vehicle battery 2000, as provided in this specification. As shown in Figure 7, the operating unit 250 includes a third housing 251, a handle 253, a switch button 255, and an indicator light 257. The third housing 251 serves as a mounting base for the other components of the operating unit 250, and these components (such as the handle 253, switch button 255, and indicator light 257) are mounted relative to the third housing 251. The third housing 251 can be integrally molded with the first housing 231, or it can be separately molded and then assembled with the first housing 231. When the third housing 251 and the first housing 231 are separately molded and then assembled, the third housing 251 can be connected to the first housing 231. Specifically, the third housing 251 can be fixedly connected to the first housing 231, or it can be detachably connected. The fixed and detachable connection methods are the same as those described above and are not further described here. The material of the third housing 251 can be stainless steel, aluminum, hard plastic, etc. This specification does not limit the shape and material of the third housing 251.

[0076] The handle 253 serves as the carrying portion of the battery 2000, making it convenient for the user to handle and place the battery 2000, and to remove and install the battery 2000. The handle 253 is mounted on the third housing 251 and mechanically connected thereto. The handle 253 can be mounted anywhere on the third housing 251, for example, on the end face of the third housing 251 away from the power supply unit 230. For another example, the handle 253 can be mounted on any of the four side faces of the operating portion 250 that intersect with the end face of the operating portion 250 away from the power supply unit 230. The mechanical connection can be at least one of a threaded connection, a keyed connection, a welded connection, a riveted connection, a pin connection, a snap-fit ​​connection, or an adhesive connection. The shape of the handle 253 can be any shape, for example, at least one of a C-shaped handle, an L-shaped handle, or a recessed handle. This specification does not limit the mounting position of the handle 253, the connection method between the handle 253 and the third housing 251, or the shape of the handle 253.

[0077] The switch button 255 can be mounted on the third housing 251. Specifically, the switch button 255 can be mounted anywhere on the third housing 251. For example, the switch button 255 can be mounted on the third housing 251 and located on the end surface away from the power supply unit 230. For another example, the switch button 255 can be mounted on any of the four side surfaces that intersect with the end surface of the operating unit 250 away from the power supply unit 230. This specification does not limit this. The switch button 255 can control the opening and closing of the battery 2000. Specifically, the switch button 255 is electrically connected to the switch control port of the control circuit, and the control circuit is electrically connected to the power supply unit 230. When the switch button 255 is triggered, the circuit between the power supply unit 230 and the interface unit 210 is connected, allowing current to flow from the power supply unit 230 to other electrical components. When the switch button 255 is in the off state, the circuit between the power supply unit 230 and the interface unit 210 is disconnected, and current cannot flow from the power supply unit 230 to other electrical components.

[0078] The indicator light 257 can be mounted on the third housing 251. Specifically, the indicator light 257 can be mounted anywhere on the third housing 251, for example, on the end surface of the third housing 251 away from the power supply unit 230. Another example is that the indicator light 257 can be mounted on any of the four side surfaces intersecting the end surface of the operating unit 250 away from the power supply unit 230. This specification is not limited to this. The indicator light 257 can be used to display the status of the battery 2000. The battery 2000 status can be at least one of the battery charge level, battery operating status, battery charging status, or battery discharge status. Furthermore, the indicator light 257 is electrically connected to an indicator port of the control circuit, which is electrically connected to the power supply unit 230. The control circuit detects the battery cell status signal and activates the indicator light 257 to display the status. The indicator light 257 can display the battery status in various ways, for example, by using different brightness levels to indicate the battery status according to the battery status. Another example is that the light changes color to indicate the battery status according to the battery status. This specification is not limited to this.

[0079] It should be noted that the electrical connection described above can be achieved in a variety of ways, such as wire connection, plug and socket connection, contact connection, direct welding, etc.
