Description

Technical Field

[0001] This specification relates to the technical field of batteries, and particularly to a battery for a vehicle. Background Art

[0002] With the development of technology, various types of commuting vehicles have emerged in people's lives, bringing great convenience to people's lives. In particular, the use of short-distance commuting vehicles is increasing day by day, such as scooters, tricycles, balance bikes, and so on. In some common commuting vehicles, batteries are often added to provide power for these commuting vehicles or add some auxiliary functions, such as timing, step counting, heart rate detection, weather forecast, and so on.

[0003] Currently, one type of commuting vehicle uses a fixed battery, which is fixedly integrated in the commuting vehicle. Another type is the battery swapping method, where the battery is detachably installed on the vehicle body. In the battery swapping method, one type of battery can only be adapted to a single model of vehicle, and the versatility of the battery is poor, with a low usage frequency and high cost.

[0030] The following description provides specific application scenarios and requirements of this specification, aiming to enable those skilled in the art to manufacture and use the content in this specification. For those skilled in the art, various partial modifications to the disclosed embodiments are obvious, and without departing from the spirit and scope of this specification, the general principles defined here can be applied to other embodiments and applications. Therefore, this specification is not limited to the shown embodiments, but has the broadest scope consistent with the claims.

[0031] The terms used here are only for the purpose of describing specific example embodiments and are not restrictive. For example, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" used here may also include the plural forms. When used in this specification, the terms "comprising", "including", and / or "containing" mean that the associated integers, steps, operations, elements, and / or components exist, but do not exclude the existence 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.

[0032] 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. That is to say, X can include only any combination of A, B, and C, or can include any combination of A, B, and C as well as other possible content / elements at the same time. Any combination of A, B, and C can be A, B, C, AB, AC, BC, or ABC.

[0033] In this application, unless otherwise explicitly stated, the associated relationship generated between structures can be a direct associated relationship or an indirect associated 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 can be indirectly connected to B; for another example, when describing "A is above B", unless it is explicitly stated that A is directly above B (A and B are adjacent and A is above B), it should be understood that A can be directly above B, or A can be indirectly above B (there are other elements between A and B and A is above B). And so on.

[0034] In view of the following description, these features of this specification and other features, as well as the operations and functions of the related components of the structure, and the combination and manufacturing economy of the components can be significantly improved. Referring to the attached drawings, all of these form a part of this specification. However, it should be clearly understood that the drawings are only for the purpose of illustration and description and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0035] In a battery-swapping electric vehicle, whether the battery is compatible with the electric vehicle and / or the charging device depends on whether the battery interface is compatible with the electric vehicle and / or the charging device. In the prior art, usually only one battery interface is provided for the battery, which results in poor universality of the battery. It can only be connected to a single electric vehicle and / or charging device that is compatible with the battery interface, and cannot be connected to other electric vehicles and / or charging devices that are not compatible with this battery interface, nor can it meet the charging requirements in different scenarios.

[0036] Figure 1 The assembly schematic diagram of the battery compartment 1000, the electric vehicle 001, and the charging device 002 provided in some exemplary embodiments according to this application is shown. As Figure 1 shown, some embodiments of this application provide a battery 2000 for a vehicle, enabling the battery 2000 to be compatible with different types of electric vehicles 001 and / or charging devices 002.

[0037] The commuting vehicle 001 can be any kind of transportation means for short-distance travel, commuting, leisure and entertainment, etc. For example, the commuting vehicle 001 can be an electric bicycle, which combines the riding mode of a traditional bicycle with an electric assistance system, and the rider can move forward by pedaling manually or being driven by a battery. For example, the commuting vehicle 001 can be an electric scooter, which is powered by electricity, and some models can also be folded for carrying. For example, the commuting vehicle 001 can be an electric unicycle, which is provided with two parallel wheels, powered by a battery, and also has a built-in balance control system for the rider to ride while standing. For another example, the commuting vehicle 001 can be an electric four-wheel commuting vehicle, which has a stable four-wheel structure, powered by a battery, and the user can travel smoothly while sitting on the seat. It should be noted that those skilled in the art should understand that other commuting vehicles 001 are also within the protection scope of this specification.

[0038] The charging device 002 can be any device that can replenish electrical energy to the battery. For example, the charging device 002 can be a portable charger, which can be equipped with the vehicle to replenish electrical energy to the battery at any time. For example, the charging device 002 can be a fixed charging device installed in the charging area, and the battery can be replenished with electrical energy in the charging area after being removed from the commuting vehicle 001. This specification does not limit the type of the charging device 002.

[0039] The commuting vehicle 001 and / or the charging device 002 can include a battery compartment 1000. The battery compartment 1000 can be the installation base for the battery 2000. The battery compartment 1000 can be a thin-walled shell structure with a hollow interior. The battery 2000 can be installed inside the battery compartment 1000. The battery compartment 1000 can be in any ergonomic shape, such as a cuboid, a cube, a cylinder, or a combination thereof. The following content will be described by taking the battery compartment 1000 as a cuboid as an example. The material of the battery compartment 1000 can be any material, such as aluminum alloy, magnesium alloy, stainless steel, carbon fiber composite material, etc. This specification does not limit the shape and material of the battery compartment 1000.

[0040] Figure 2 Shows an installation schematic diagram of the battery compartment 1000 and the battery 2000 provided by some exemplary embodiments in the present application. As Figure 1 and Figure 2As shown, 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 jointly form a hollow shell structure, and an accommodation compartment 150 is formed inside the shell structure. The accommodation compartment 150 can accommodate the battery 2000 to play a role in protecting the battery 2000 and preventing dust. The main compartment body 110 and the compartment cover 130 can be connected by a detachable connection method to facilitate the replacement of the battery 2000. The detachable connection can be a snap connection, a hinge connection, etc. This specification does not limit this. In some embodiments, the battery compartment 1000 can also be formed by installing two or more shells together, and this specification will not elaborate on this.

[0041] When the battery compartment 1000 is a cuboid, the main compartment body 110 includes a bottom surface 111 and four side walls 113. Among them, the bottom surface 111 and the four side walls 113 are located on the side of the main compartment body 110 close to the accommodation compartment 150. The bottom surfaces 111 are arranged opposite to each other and intersect with the side walls 113 and the compartment cover 130 respectively. At least one peripheral interface is fixedly arranged on the main compartment body 110. Specifically, the peripheral interface is fixedly arranged on the bottom surface 111 and / or the side walls 113. There can be various ways to set the peripheral interface. For example, the peripheral interface can be set on the bottom surface 111; the peripheral interface can also be set on the side walls 113; or when the main compartment body includes multiple peripheral interfaces, these multiple peripheral interfaces can also be respectively set on the bottom surface 111 and the side walls 113. Each peripheral interface can be adapted to the battery 2000. The functions of these peripheral interfaces are the same, and both can perform power transmission and data communication. The at least one peripheral interface can be any number, such as 1, 2, 3, 4, etc. Those skilled in the art should know that the setting positions of other peripheral interfaces are also within the protection scope of this specification.

[0042] In some embodiments, the battery compartment 1000 includes a first peripheral interface 115. At this time, after the battery 2000 is inserted into the battery compartment 1000, the first peripheral interface 115 is coupled with the battery 2000 to complete the power transmission. In some embodiments, the battery compartment 1000 includes a second peripheral interface 117. At this time, after the battery 2000 is inserted into the battery compartment 1000, the second peripheral interface 117 is coupled with the battery 2000 to complete the power transmission. Thus, the battery 2000 can be adaptively connected to various types of electric scooters or charging devices with different interfaces.

[0043] Figure 3 The structure diagram of a battery 2000 of a vehicle provided in this specification is shown from a first perspective. As Figure 3As shown in the figure, this specification provides a battery 2000 for a vehicle. The battery 2000 is the main power source of the scooter 001, capable of storing electrical energy and converting it into mechanical energy when the electric vehicle is running, thereby driving the scooter 001 to move. The battery 2000 can be installed on the scooter 001 and / or the charging device 002. Specifically, the battery 2000 can be adapted to the above-mentioned accommodation bin 150. When the battery 2000 is installed on the scooter 001 and / or the charging device 002, the battery 2000 is installed in the accommodation bin 150 of the above-mentioned battery compartment 1000. The so-called "adaptation" can be the adaptation of shape and size. The type of the battery 2000 can be at least one of lead-acid batteries, lithium-ion batteries, lithium iron phosphate batteries, or nickel-metal hydride batteries.

[0044] In Figure 3 it, the battery 2000 includes an interface part 210, a power supply part 230, an operation part 250, and a control circuit (not shown in the figure). Among them, the power supply part 230 stores energy through chemical reactions and converts chemical energy into electrical energy during the operation of the battery 2000. The interface part 210 can transmit the electrical energy of the power supply part 230 to other electrical components of the scooter 001 or be connected to the charging device 002 for electrical energy replenishment. The operation part 250 can display the state of the battery 2000 and can also control the opening and closing of the battery 2000, improving the user experience. The control circuit can receive the control commands of the operation part 250 and can also transmit the state information of the battery 2000 to the operation part 250. Through the mutual cooperation of the interface part 210, the power supply part 230, the operation part 250, and the control circuit, the normal operation of the battery 2000 is realized.

[0045] Furthermore, the power supply part 230 and the control circuit are first electrically connected, then the control circuit is respectively electrically connected to the operation part 250 and the interface part 210, and then the interface part 210 is electrically connected to the scooter 001 and / or the charging device 002 to complete the monitoring of the state of the battery 2000, the control of the opening and closing of the battery 2000, and the data transmission between the battery 2000 and the scooter 001 and / or the charging device 002. On the one hand, the control circuit can monitor the state of the power supply part 230 in real time and output appropriate control signals to the operation part 250 according to the monitoring data, and the operation part 250 receives this control signal and displays it. On the other hand, the operation part 250 can make the circuit between the control circuit and the interface part 210 be connected or closed to control the current to flow from the power supply part 230 to other electrical components or prohibit the current from flowing from the power supply part 230 to other electrical components. On the third hand, the power supply part 230 can perform electrical energy transfer and communication transmission with the scooter 001 and / or the charging device 002 through the control circuit and the interface part 210.

[0046] The control circuit can be installed inside the battery 2000, for example, inside the interface part 210, inside the operating part 250. The control circuit includes a plurality of ports, and the control circuit can be connected to the power supply part 230, the operating part 250, and the interface part 210 through the plurality of ports. The plurality of ports may include a battery connection port, a communication port, a switch control port, and an indicator light port, etc. As described above, the electrical connection between the power supply part 230, the control circuit, the operating part 250, and the interface part 210 can be connected through the plurality of ports.

[0047] 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 pole of the power output of the power supply unit 230, and the negative connection terminal is connected to the negative pole of the power output of the power supply unit 230, so as to realize the monitoring of the state of the power supply unit 230. Specifically, the control circuit can monitor various state 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 other state parameter monitoring is also within the scope of protection of this specification.

[0048] The control circuit can be electrically connected to the operating part 250 through the indicator port and the switch control port. Specifically, the indicator port is electrically connected to the display component of the operating part 250 to display the state of the battery 2000. The indicator port can transmit the state parameters of the power supply part 230 monitored by the control circuit to the display component of the operating part 250. The switch control port is electrically connected to the switch control component of the operating part 250 to control the opening and closing of the battery 2000.

[0049] The control circuit can be electrically connected to the interface unit 210 through a communication port, a ground authentication hard-wire detection port, and a 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 vehicle 001 and / or the charging device 002 through the interface unit 210. Specifically, the control circuit can use a variety of communication ports to exchange data and transmit control instructions with the vehicle 001 and / or the charging device 002. The various communication ports can be CAN (Controller Area Network) communication ports, I 2 One of the 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.

[0050] The ground authentication hard-wire detection port can be electrically connected to the interface part 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 exchange data 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.

[0051] The charging wake-up port can be electrically connected to the interface part 210. In some specific scenarios, the control circuit can control the battery 2000 to execute the wake-up program 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 perform charging wake-up regularly through the charging wake-up port to maintain the activity of the battery 2000. For example, when the battery 2000 is connected to the vehicle 001 and / or the charging device 002, the vehicle 001 and / or the charging device 002 will send a charging signal through the charging wake-up port, and the control circuit detects the charging signal and starts the charging program. For example, when the battery 2000 is connected to the vehicle 001 and / or the charging device 002, the control circuit detects that the state of the battery 2000 has changed, and DET (Detection) is pulled down as a notification signal of the state change, and the battery 2000 executes the charging wake-up program. For another example, when the battery 2000 is connected to the vehicle 001, the battery 2000 outputs an output voltage of a preset voltage value through the control circuit, and the control circuit reduces the output voltage to 0 after a preset duration, thereby actively waking up the charging. Those skilled in the art should understand that other charging wake-up scenarios are also within the protection scope of this specification.

[0052] The interface unit 210, power supply unit 230, and operation unit 250 connected to the control circuit can be integrally formed or can be formed as independent units and then assembled together to form the battery 2000. When the interface unit 210, power supply unit 230, and operation unit 250 are formed as independent units and then assembled to form the battery 2000, the power supply unit 230 serves as the mounting base for other components. Specifically, the power supply unit 230 includes a first end 235 and a second end 237. The interface unit 210 is mounted on the first end 235 of the power supply unit 230. The mounting method can be a fixed connection or a detachable connection. The operation unit 250 is mounted on the second end 237 of the power supply unit 230, and the mounting method can be a fixed connection or a detachable connection. Further, the fixed connection can be a threaded connection, welding, riveting, bonding, snap connection, mortise and tenon connection, etc. The detachable connection can be a snap connection, hinge connection, and key connection, etc. This specification does not limit this.

[0053] Figure 4 The structural schematic diagram of the power supply unit 230 of the battery 2000 provided according to some embodiments of this specification is shown, as Figure 4 shown, the power supply unit 230 can be the main energy storage component of the battery 2000. The power supply unit 230 can include a first housing 231 and a battery body 233. The first housing 231 can be the mounting base of the battery body 233 and play a supporting role for the battery body 233. The battery body 233 is at least partially fixedly installed inside the first housing 231. The first housing 231 can be adapted to the above-mentioned battery compartment 1000, and the adaptation can be the adaptation of shape and size. The material of the first housing 231 can be stainless steel, aluminum, hard plastic, etc. This specification does not limit the shape and material of the first housing 231.

[0054] The battery body 233 includes at least one battery cell. The at least one can be 1, 2, 3, 4, 6, etc., and this is not limited here. When the number of battery cells is multiple, in some embodiments, the multiple battery cells are connected in series through internal conductors to form the battery body 233. For example, if the voltage of the target battery body 233 is 48V and the current is 40A, then 4 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 through internal conductors to form the battery body 233. For example, if the voltage of the target battery body 233 is 48V and the current is 40A, then 4 battery cells with a voltage of 48V and a current of 10A can be selected and connected in parallel. Among them, the positive and negative electrodes of the battery power output are located on the first housing 231 and face the side of the interface unit 210.

[0055] The interface part 210 is the port for the power output of the power supply part 230, and the electric energy and status of the power supply part 230 can be output through the interface part 210. Specifically, at least a part of the interface part 210 is electrically connected to the battery body 233 of the power supply part 230, and at least a part of the interface part 210 is electrically connected to the control circuit. When the battery 2000 is connected to the mobility vehicle 001 and / or the 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 the charging device 002 through the interface part 210 to perform data exchange and command transmission.

[0056] Figure 5 shows according to this specification Figure 3 a schematic structural view of the interface part 210 of the battery 2000; Figure 6 shows a right view of the battery 2000 provided according to some embodiments of this specification; Figure 7 shows a top view of the battery 2000 provided according to some embodiments of this specification. As Figures 5 - 7 shown, the interface part 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. Among them, the second housing 211 can be the mounting base of the interface part 210 and play a supporting role. Other parts of the interface part 210 can be mounted with the second housing 211 as a carrier. For example, 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 can be provided on the second housing 211. The second housing 211 can be integrally formed with the above-mentioned first housing 231, or can be formed separately from the first housing 231 and then assembled. When the second housing 211 is formed separately from the first housing 231 and then assembled, the second housing 211 can be connected to the first housing 231. Specifically, the second housing 211 can be fixedly connected to the first housing 231 or can be detachably connected. The fixed connection and detachable connection methods are the same as those in the above-mentioned specification and will not be elaborated here. The material of the second housing 211 can be stainless steel, aluminum, hard plastic, etc. This specification does not limit the shape and material of the second housing 211.

[0057] The first interface surface 217 is arranged on the second shell 211 and is located on the end surface of the interface part 210 away from the power supply part 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 arranged on the first interface surface 217 is coupled with the first peripheral interface 115 arranged on the bottom surface 111 of the battery compartment 1000 and completes the electrical connection. Among them, the adaptation can be adaptation in shape and size.

[0058] The first battery interface 213 includes a base 2131, and the base 2131 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, so that protection is formed 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.

[0059] The presence of multiple contacts can enable the battery 2000 to achieve circuit connectivity with the vehicle for mobility 001 and / or the charging device 002. The multiple contacts include at least one communication contact array and at least one power contact array. At least one communication contact array can enable communication between the battery 2000 and the vehicle for mobility 001 and / or a third-party communication device. 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 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.

[0060] For the convenience of illustration, the following description takes the first battery interface 213 including one power contact array and two communication contact arrays as an example. In this case, the two communication contact arrays are distributed on both sides of one 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 scope of protection of this specification.

[0061] The power contact array is electrically connected to the battery body 233, including two first negative contacts 2133-1 and one first positive contact 2133-3. The two first negative contacts 2133-1 are electrically connected to the power output negative pole of the battery body 233, the first positive contact 2133-3 is electrically connected to the power output positive pole, and the first positive contact 2133-3 is between the two first negative contacts 2133-1. When the battery 2000 is connected to the vehicle 001 and / or the charging device 002, any one of the two first negative contacts 2133-1 is connected to the battery body 233, and completes the circuit conduction together with the first positive contact 2133-3, and the other first negative contact 2133-1 becomes a standby connection to prevent the first negative contact 2133-1 from poor contact or damage, thereby increasing the reliability of the connection.

[0062] 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 both sides of a power contact array. When the battery 2000 is electrically connected to the walking vehicle 001 and / or the charging device 002, the use of the two communication contact arrays may be different in different scenarios. For example, one of the two communication contact arrays is used for communication transmission, and the other is designed as a backup. When one communication contact array fails, the other communication contact array can still 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 and be responsible for different data streams respectively, so that the data saturation processed by a single communication contact array can be avoided, affecting the data transmission efficiency and response speed. For another example, when the walking vehicle 001 and / or the charging device 002 are upgraded or new functions are added, one of the two communication contact arrays can be assigned new communication tasks or support new communication protocols according to demand. When the number of communication contact arrays is other numbers, the functions and usage scenarios of multiple communication contact arrays are also as described above, and will not be repeated here.

[0063] Each of the two communication contact arrays includes four contacts. The four contacts can be used for data transmission, safety 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 ports 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 communicates with 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 feedback the battery 2000 status information, control instructions, configuration data, fault diagnosis information, system synchronization and coordination information monitored by the control circuit to the mobility vehicle 001 and / or the charging device 002, and receive control instructions and configuration information from the mobility vehicle 001 and / or the charging device 002.

[0064] The third contact 2135-5 is electrically connected to the ground authentication hard wire detection port of the control circuit. As described above, on the one hand, the third contact 2135-5 serves as an identity verification contact to authenticate the mobility vehicle 001 and / or the charging device 002 connected to the battery 2000. Only the authenticated mobility vehicle 001 and / or charging device 002 can access the battery 2000 and perform data interaction with the battery 2000. On the other hand, the third contact 2135-5 can be used as a ground monitoring contact to detect whether the battery 2000 is properly grounded to ensure electrical safety.

[0065] The fourth contact 2135-7 is electrically connected to the charging wake-up port in the control circuit. In a scenario where the battery 2000 is connected to the mobility vehicle 001 and the battery 2000 has insufficient power, the mobility vehicle 001 will send a charging signal to the fourth contact 2135-7, and the fourth contact 2135-7 will transmit the charging signal to the control circuit. The control circuit detects the charging signal and starts the charging program. In a scenario where the battery 2000 is connected to the mobility vehicle 001, the control circuit first outputs an output voltage with 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 performing wake-up charging. When the battery 2000 is connected to the charging device 002, the control circuit detects a change in the state of the battery 2000 through the fourth contact 2135-7, and when the DET of the battery 2000 is pulled low, the charging program is started. Those skilled in the art should understand that other charging wake-up scenarios are also within the scope of protection of this specification.

[0066] As described above, in addition to the first battery interface 213, the interface portion 210 further includes a second set of battery interfaces to provide a connection method different from that of the first battery interface 213 for the battery 2000. The 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 face of the interface portion 210 away from the power supply portion 230. The recessed space 219 is formed by any two intersecting side surfaces among 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 set of solutions that can charge and discharge the battery 2000, the second battery interface 215 is adapted to the second peripheral interface 117. The second battery interface 215 is coupled to the second peripheral interface 117 and completes the electrical connection. Among them, the adaptation may be in terms of shape and size.

[0067] Specifically, the 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 to form the recessed space 219. The recessed space 219 includes the second interface surface 218. Among them, 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 disposed 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 is coupled to the second battery interface 215 on the second interface surface 218, and the second opening 2193 can allow the wire of the second peripheral interface 117 to enter the recessed space 219.

[0068] The recessed space 219 further includes a second protective wall 2195. The second protective wall 2195 extends from the first side surface 2161 to the second interface surface 218 and is disposed around the second interface surface 218. The second protective wall 2195 protects the second battery interface 215 from the side surface of the second interface surface 218.

[0069] The second battery interface 215 is different in form from the first battery interface 213 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. At least one communication contact array can realize the communication between the battery 2000 and the vehicle 001 and / or the third-party communication device. At least one power contact array can realize the output of electric energy of the battery 2000 and the input of electric energy of 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 A schematic diagram of the structure of the second battery interface provided according to some embodiments of the present specification is shown. For the convenience of presentation, the following description takes the second battery interface 215 including a power contact array and a communication contact array as an example. In this case, a communication contact array is arranged on one side of the power contact array. It should be understood by those skilled in the art that other numbers of power contact arrays and communication contact arrays are also within the scope of protection of the present specification.

[0070] 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 power output negative pole of the battery body 233, and the second positive contact 2151-3 is electrically connected to the power output positive pole.

[0071] The at least one communication contact array is electrically connected to the control circuit. Specifically, as described above, taking one communication contact array as an example, one communication contact array is distributed on one side of one power contact array. One communication contact array includes four contacts. The four contacts can respectively perform data transmission, safety 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 wire 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 will not be elaborated here.

[0072] In addition, the battery 2000 further includes a guiding device 270. When the first battery interface 213 is coupled to the first peripheral interface 115, the guiding device 270 can guide the first battery interface 213. The guiding 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, and linear motion guiding 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, and the movement of the battery 2000 along a preset path is achieved through the cooperation of the guide post and the guide sleeve.

Those skilled in the art should understand that other types of guiding devices 270 are also within the protection scope of this specification.

[0073] The interface portion 210 further includes a second battery interface cover 220. When the battery 2000 is closed, the second battery interface cover 220 can cover the first opening 2191 and the second opening 2193 to prevent moisture, dust, or other impurities from entering and affecting the performance of the second battery interface 215. Among them, the second battery interface cover 220 is movably connected to the second interface surface 218 or the second retaining wall 2195. The so-called movable connection can be snap connection, magnetic attraction connection, spring connection, hinge connection, and so on. This specification does not make a limitation in this regard.

[0074] The operation part 250 can facilitate the user to lift the battery 2000, thus completing the installation and disassembly.

As Figure 7 shown, the operation part 250 includes a third housing 251, a handle 253, a switch button 255, and an indicator light 257. Among them, the third housing 251 is the installation base for other parts of the operation part 250, and other parts (such as the handle 253, the switch button 255, and the indicator light 257) are installed based on the third housing 251. The third housing 251 can be integrally formed with the above-mentioned first housing 231, or the third housing 251 and the first housing 231 can be formed separately and then assembled.

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, enabling 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 cut off, and current cannot flow from the power supply unit 230 to other electrical components.

[0077] The indicator light 257 can be installed on the third housing 251. Specifically, the indicator light 257 can be installed at any position on the third housing 251.
