[0001] This application relates to the field of battery technology, and in particular to a battery wake-up system and a battery. Background Technology

[0002] In existing technologies, batteries are kept in shipping mode during transportation or storage. If maintenance (such as firmware upgrades) or fixing internal software vulnerabilities is required, the battery needs to be woken up. Common wake-up methods include charger insertion, load connection, button activation, wired communication, and Bluetooth Low Energy (BLE) mobile communication. All of these require the battery to be connected to a physical cable or in direct contact with the battery itself, meaning the outer packaging needs to be removed to wake the battery and switch it to working mode. Unpacking the battery is labor-intensive and can easily compromise the integrity of the packaging; repackaging the battery afterwards also incurs additional costs. Summary of the Invention

The components of the embodiments of this application described and illustrated herein can typically be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0025] In existing technologies, battery maintenance (such as firmware upgrades) or fixing internal software vulnerabilities requires waking up the battery while it is in transit. Common wake-up methods include charger insertion, load connection, button activation, and wired communication, all of which require the battery to be connected to a physical cable or in direct contact with the battery itself. Even when using external devices such as Bluetooth or wireless communication modules for battery maintenance or vulnerability repair, the battery still needs to be woken up during storage or transportation before the internal software can be upgraded wirelessly. However, since the battery remains unopened during storage or transportation, connecting it to a physical cable or allowing direct contact with the battery requires unpacking, resulting in a significant workload and potentially affecting the integrity of the packaging, thus impacting the user experience.

[0026] Based on this, this application provides a battery wake-up system and a battery. By incorporating a sensing module and a power module within the battery, after the wake-up module generates an AC signal and correspondingly produces a magnetic field, the radio frequency sensing device of the sensing module generates an induced electromotive force to produce a wake-up signal. Upon receiving the wake-up signal, the power module provides a preset power supply to the battery management system within the battery, causing the battery management system to exit transport mode, thus waking up the battery. This solves the technical problem of high costs caused by unpacking the battery to wake it up in the prior art, achieving the technical effects of reducing the cost of battery wake-up and improving efficiency. Specifically: Please see Figure 1 , Figure 1 This is a schematic diagram of a battery wake-up system provided in an embodiment of this application. Figure 1 As shown, the battery wake-up system provided in this application embodiment includes: a wake-up module 101 configured to generate an AC signal and generate a magnetic field according to the AC signal, the wake-up module being located outside the battery BAT; the battery BAT includes a sensing module 102 and a power module 103, the sensing module including a radio frequency sensing device, the number of wake-up modules being the same as the number of radio frequency sensing devices, and the wake-up modules and the radio frequency sensing devices corresponding one-to-one, wherein the radio frequency sensing device is configured to generate an induced electromotive force in response to the magnetic field generated by its corresponding wake-up module, so that the sensing module generates a wake-up signal, the power module providing a preset power supply in response to the wake-up signal, the preset power supply being used to supply power to the battery management system of the battery to wake up the battery.

[0027] In this application, the battery is in transport mode during transportation or storage in a warehouse. During this time, the internal modules of the battery are not operational to prevent power consumption. In other words, when the battery is in transport mode, the battery management system switches to transport mode, the battery management system is not operational, and the power module does not supply power to the battery management system.

[0028] In other words, the wake-up module is independently located outside the battery, while the sensing module and power module are encapsulated inside the battery. The wake-up module and the sensing module are not directly connected. Technicians can place the wake-up module outside the battery. The AC signal generated by the wake-up module creates a magnetic field that radiates to the sensing module. The sensing module then generates an induced electromotive force and produces a wake-up signal. This means that the sensing module can wake up the battery without direct contact with it.

[0029] Then, the sensing module sends the generated wake-up signal to the power module. After receiving the wake-up signal, the power module generates a preset power supply. The power of the preset power supply is transferred to the battery management system of the battery so that the power module can supply power to the battery management system. The battery management system is powered on and exits the transport mode, thereby waking up the battery.

[0030] Please see Figure 2 , Figure 2 This is a circuit diagram of the wake-up module provided in an embodiment of this application. Figure 2 As shown, the wake-up module includes: a power supply V1; an activation signal source V2 connected to the power supply for generating the AC signal; and a transmitting resonant circuit 201 connected to the activation signal source and the power supply for generating a magnetic field in response to the AC signal.

[0031] Specifically, the activation signal source generates an AC signal, and this AC signal matches the frequency of the sensing module, enabling the sensing module to generate a wake-up signal. Furthermore, the power supply provides electrical energy to the transmitting resonant circuit, which includes an inductor L and a capacitor C connected in parallel, allowing the transmitting resonant circuit to radiate the AC signal generated by the activation signal source. For example, the inductor in the transmitting resonant circuit can be understood as a wake-up coil, which converts the AC signal into an alternating magnetic field and radiates it outwards.

[0032] Among them, such as Figure 2 As shown, the wake-up module further includes: an amplifying element Q1, the control terminal of which is connected to the activation signal source, the first connection terminal of which is connected to the positive terminal of the power supply, and the second connection terminal of which is connected to the transmitting resonant circuit; and a current-limiting resistor R0, which is disposed between the control terminal of the amplifying element and the activation signal source.

[0033] For example, the amplifying element can be a transistor or a field-effect transistor with amplification function, thereby amplifying the AC signal provided by the activation signal source. A current-limiting resistor is placed between the control terminal of the amplifying element and the activation signal source to limit the current. Furthermore, the AC signal provided by the activation signal source is amplified by the amplifying element and then radiated externally through the transmitting resonant circuit to form a magnetic field. Wherein, such as Figure 2 As shown, the amplifying element is an NPN transistor.

[0034] Specifically, the positive terminal of the power supply is connected to the collector of the transistor, the emitter of the transistor is connected to one side of the inductor of the emitter resonant circuit, the other side of the inductor of the emitter resonant circuit is grounded to GND, the capacitor of the emitter resonant circuit is connected in parallel across the inductor, the signal output terminal of the activation signal source is connected to one side of the current limiting resistor, the ground terminal of the activation signal source is grounded, and the other side of the current limiting resistor is connected to the base of the transistor.

[0035] Please see Figure 3 , Figure 3 This is a circuit diagram of the sensing module provided in an embodiment of this application. Figure 3As shown, the sensing module 102 includes: a first radio frequency sensing device and a second radio frequency sensing device, used to respond to the AC signal and generate an induced electromotive force; and a logic circuit U, which outputs the wake-up signal when it simultaneously receives the induced electromotive force generated by the first radio frequency sensing device and the second radio frequency sensing device.

[0036] In other words, when the first radio frequency sensor senses the magnetic field generated by the AC signal of its corresponding wake-up module, it generates an induced electromotive force and provides a high-level signal to the logic circuit. When the second radio frequency sensor senses the magnetic field generated by the AC signal of its corresponding wake-up module, it generates an induced electromotive force and provides another high-level signal to the logic circuit, so that the logic circuit outputs a wake-up signal when it receives two high-level signals at the same time.

[0037] The radio frequency sensing device is positioned to match the direction of the magnetic field lines of the magnetic field generated by its corresponding wake-up module, so as to limit the radio frequency sensing device to generate an induced electromotive force only in response to the magnetic field generated by its corresponding wake-up module.

[0038] In other words, the first radio frequency sensing device is positioned such that it generates an induced electromotive force within the magnetic field generated by the corresponding wake-up module, and the second radio frequency sensing device is positioned such that it generates an induced electromotive force within the magnetic field generated by the corresponding wake-up module. Furthermore, the radio frequency sensing device generates an induced electromotive force only in response to the magnetic field of its corresponding wake-up module. This restricts the first and second radio frequency sensing devices of a battery to generate an induced electromotive force only in response to their corresponding wake-up module, thereby preventing the wake-up module from simultaneously waking up multiple batteries.

[0039] For example, the wake-up module includes a first wake-up coil and a second wake-up coil. The first radio frequency sensing device includes a first induction coil, and the second radio frequency sensing device includes a second induction coil. The magnetic field lines of the first induction coil are aligned with the magnetic field lines of its corresponding first wake-up coil, and the magnetic field lines of the second induction coil are aligned with the magnetic field lines of its corresponding second wake-up coil. The magnetic field lines of the first induction coil and the magnetic field lines of the second induction coil are perpendicular to each other, so that the first wake-up coil and the second wake-up coil simultaneously excite their respective corresponding induction coils within a battery to wake up only one battery.

[0040] In other words, the number of induction coils and wake-up coils are the same and correspond one-to-one. The first induction coil corresponds to the first wake-up coil, and the second induction coil corresponds to the second wake-up coil. The first induction coil is located in the magnetic field generated by the first wake-up coil and generates an induced electromotive force. The second induction coil is located in the magnetic field generated by the second wake-up coil and generates an induced electromotive force. Due to the limitations of the logic circuit, a wake-up signal can only be output when both the first and second induction coils generate induced electromotive forces. At this time, the power module receives the wake-up signal and provides the preset power to the battery management system to wake up the battery. Thus, a battery can only be woken up when the first and second wake-up coils act synchronously on their corresponding induction coils.

[0041] Furthermore, when the frequency of the magnetic field provided by the first radio frequency sensing device and its corresponding wake-up module is matched, the first radio frequency sensing device can generate an induced electromotive force with maximum efficiency; similarly, when the frequency of the magnetic field provided by the second radio frequency sensing device and its corresponding wake-up module is matched, the second radio frequency sensing device can generate an induced electromotive force with maximum efficiency. To prevent a wake-up module from simultaneously waking up the first and second radio frequency sensing devices, the magnetic field lines of the first induction coil should be perpendicular to the magnetic field lines of the second induction coil, i.e., the magnetic field lines of the two induction coils should be at 90 degrees to each other.

[0042] In other words, the magnetic field generated by the first wake-up coil only induces an electromotive force in the first induction coil of one battery, and the magnetic field generated by the second wake-up coil only induces an electromotive force in the second induction coil of one battery, thus preventing a single wake-up coil from simultaneously waking up the first and second induction coils. For example, the first and second induction coils can be positioned diagonally opposite each other on the battery to further reduce the possibility of a single wake-up module simultaneously waking up the first and second radio frequency sensing devices.

[0043] Alternatively, the resonant circuit of the wake-up module and its corresponding RF sensing device can be understood as a transformer. The resonant circuit of the wake-up module can be understood as the primary side of the transformer, and the RF sensing device can be understood as the secondary side of the transformer. In this way, the RF sensing device generates an induced electromotive force in response to the magnetic field generated by the AC signal of the wake-up module.

[0044] Specifically, such as Figure 3As shown, the logic circuit U is an AND gate logic circuit. The first radio frequency sensing device includes a first induction coil L1, and the second radio frequency sensing device includes a second induction coil L2. The sensing module also includes a first resistor R1, a first capacitor C1, a second resistor R2, and a second capacitor C2. The first resistor and the first induction coil are connected in series, the first capacitor is connected in parallel with the first resistor and the first induction coil, the second resistor and the second induction coil are connected in series, and the second capacitor is connected in parallel with the second resistor and the second induction coil. One side of the first capacitor is connected to one input pin of the AND gate logic circuit, and the other side of the first capacitor is grounded. One side of the second capacitor is connected to the other input pin of the AND gate logic circuit, and the other side of the second capacitor is grounded.

[0045] In other words, the magnetic field generated by the first wake-up coil based on the received AC signal acts on the first induction coil L1, and the magnetic field generated by the second wake-up coil based on the received AC signal acts on the second induction coil L2. The induced electromotive force generated by the first induction coil L1 provides a high-level signal to one input pin of the AND gate logic circuit through the first resistor and the first capacitor. The induced electromotive force generated by the second induction coil L2 provides a high-level signal to the other input pin of the AND gate logic circuit through the second resistor and the second capacitor. The two input pins of the AND gate logic circuit simultaneously receive the high-level signal and output a high-level wake-up signal, so that the power supply module 103 provides power supply when it receives the wake-up signal.

[0046] The first induction coil can be an inductor or a PCB induction inductor (printed inductor) drawn through PCB (printed circuit board) traces. The second induction coil can also be an inductor or a PCB induction inductor (printed inductor) drawn through PCB (printed circuit board) traces. This application does not impose any restrictions on this, as long as the first and second induction coils can generate induced electromotive force according to the magnetic field.

[0047] Furthermore, the first induction coil and the first capacitor form a receiving resonant circuit, and the second induction coil and the second capacitor form another receiving resonant circuit. Thus, when the resonant frequency of the transmitting resonant circuit in a wake-up module is the same as that of the receiving resonant circuit in the battery, the wake-up coil only needs a small excitation current, and the receiving resonant circuit can generate an induced electromotive force accordingly. Even if there is a certain angle between the axes of the wake-up coil and the induction coil, energy can still be transferred, thereby improving the wake-up efficiency.

[0048] The first resistor, the first capacitor, the second resistor, and the second capacitor are used to adjust the sensitivity of the response to the AC signal and the duration of the output induced electromotive force.

[0049] In other words, the sensitivity of the RF sensing device in generating the induced electromotive force is adjusted by setting the resistance values ​​of the first resistor, the capacitance values ​​of the first capacitor, the resistance values ​​of the second resistor, and the capacitance values ​​of the second capacitor. Furthermore, the duration of the high-level signal provided to the input pin of the AND gate logic circuit, or the duration of the wake-up signal provided by the output pin of the AND gate logic circuit, is also adjusted. Specifically, the duration of the wake-up signal provided by the output pin of the AND gate logic circuit should ensure that the power module can provide power for a preset time period, which is not less than the minimum power-on time required for the battery management system to exit transport mode. Therefore, the duration of the wake-up signal provided by the AND gate logic circuit must be sufficient for the battery management system to exit transport mode in order to wake up the battery.

[0050] Furthermore, if only one radio frequency (RF) sensor is installed in a preset position within each battery, and since batteries are stacked during transportation or storage, with each RF sensor close to a fixed surface of the battery, placing a wake-up module on the side of the battery could lead to multiple batteries being woken up in batches. However, since battery firmware upgrades require individual operations, batch wake-ups would cause some batteries to prematurely exit the transportation mode, increasing battery power consumption and affecting storage time. Additionally, batteries being abnormally woken up by contact with magnetic fields generated by other electronic devices while in transportation mode would also cause additional power consumption, affecting storage time. Therefore, this application avoids batch wake-ups of multiple batteries and prevents abnormal battery wake-ups by using two RF sensors and requiring both sensors to simultaneously generate induced electromotive force to output a wake-up signal.

[0051] For example, after the battery is packaged, the first and second radio frequency (RF) sensors can both be positioned on a surface close to the battery package, or they can be positioned on different surfaces of the battery package. However, since the magnetic lines of force generated by the first and second RF sensors are perpendicular to each other, and the magnetic lines of force of the RF sensors and their corresponding wake-up modules are aligned, the wake-up modules for waking up the first and second RF sensors should be positioned on two mutually perpendicular surfaces of the battery to enable each module to wake up its corresponding RF sensor. Therefore, when one wake-up module wakes up the first RF sensor, it needs to be positioned near a surface after the battery package, and when the other wake-up module wakes up the second RF sensor, it needs to be positioned near another surface after the battery package to avoid mutual interference during the wake-up process.

[0052] For example, the axis of the first induction coil is vertically arranged inside the battery so that the magnetic field lines of the first induction coil are perpendicular to the horizontal plane of the battery; the axis of the second induction coil is horizontally arranged inside the battery so that the magnetic field lines of the first induction coil are perpendicular to the vertical plane of the battery; the axis of the first wake-up coil is vertically arranged outside the battery and the corresponding magnetic field lines are perpendicular to the horizontal plane of the battery; the axis of the second wake-up coil is horizontally arranged outside the battery and the corresponding magnetic field lines are perpendicular to the vertical plane of the battery.

[0053] In this design, the axis of the coil is perpendicular to the coil plane, and according to Ampere's law, the direction of the magnetic field lines should be the same as the direction of the coil's axis. Therefore, if the axis of the first induction coil is vertical, it is a coil wound vertically, its plane is horizontal, and its magnetic field lines should be vertical. Similarly, if the axis of the second induction coil is horizontal, it is a coil wound horizontally, its plane is vertical, and its magnetic field lines should be horizontal. Furthermore, to induce an electromotive force in the induction coil by the magnetic field generated by the waking coil, the magnetic field lines of the first induction coil and the second induction coil should be aligned, with the magnetic field lines of the waking coil and the magnetic field lines of the second waking coil. The magnetic field lines of the first waking coil should also be vertical, and the magnetic field lines of the second waking coil should be horizontal.

[0054] Please see Figure 4 and Figure 5 , Figure 4 A schematic diagram of the first and second induction coils provided in the embodiments of this application. Figure 1 , Figure 5 A schematic diagram of the first and second induction coils provided in the embodiments of this application. Figure 2 .like Figure 4 As shown, the magnetic field lines of the first induction coil L1 are perpendicular to the printed circuit board (PCB) on which it is located, while the magnetic field lines of the second induction coil L2 are horizontal to the PCB on which it is located. In this case, the magnetic field lines of the first and second RF sensing devices are perpendicular to each other. Figure 5As shown, a first induction coil L1 and a second induction coil L2 are disposed inside the battery BAT package. The first induction coil is positioned near the first preset surface 501 of the battery package, and the second radio frequency sensing device is positioned near the second preset surface 502 of the battery package. The first preset surface is a horizontal surface of the battery, and the second preset surface is a vertical surface of the battery. The first and second preset surfaces are adjacent to and perpendicular to each other, and the first and second induction coils are diagonally arranged inside the battery package. For example, the first and second induction coils are located at opposite corners inside the battery package. Thus, one wake-up module is positioned near the mapped position of the first radio frequency sensing device on the first preset surface to induce an electromotive force in the first radio frequency sensing device, and another wake-up module is positioned near the mapped position of the second radio frequency sensing device on the second preset surface to induce an electromotive force in the second radio frequency sensing device.

[0055] In other words, a horizontal plane of the battery package closest to the first induction coil is designated as the first preset plane, and a vertical plane of the battery package closest to the second induction coil is designated as the second preset plane. The first wake-up coil is positioned close to the projection of the first induction coil on the first preset plane, causing the first induction coil to be located within the magnetic field generated by the first wake-up coil, thereby inducing an electromotive force (EMF) in the first induction coil. Similarly, the second wake-up coil is positioned close to the projection of the second induction coil on the second preset plane, causing the second induction coil to be located within the magnetic field generated by the second wake-up coil, thereby inducing an EMF in the second induction coil.

[0056] Furthermore, in the actual battery production process, it is not necessary to force the first induction coil and the second induction coil to be placed on the same printed circuit board. It is only necessary to restrict the first induction coil and the second induction coil to be placed inside the battery package and the direction of the magnetic lines of force of the two induction coils, so as to provide a setting position for other modules inside the battery package.

[0057] Furthermore, during battery transportation and storage, the sealed batteries are packaged in boxes. The location where an induced electromotive force can be generated can be marked on the outer packaging of the battery to guide technicians to place the wake-up module in the marked location to wake up the battery.

[0058] One of the wake-up modules is placed outside the battery and close to the mapping position of its corresponding radio frequency sensing device, so that the magnetic field generated by the wake-up module acts only on the radio frequency sensing device and causes the radio frequency sensing device to generate an induced electromotive force.

[0059] Furthermore, when a wake-up module is brought near the mapped position of its corresponding radio frequency (RF) sensor, the magnetic field generated by the wake-up model acts only on that RF sensor, causing it to generate an induced electromotive force (EMF). Thus, a technician holds one wake-up module in each hand and brings them near their respective mapped positions on the battery packaging, causing both RF sensors inside the battery to simultaneously generate an induced EMF and produce a wake-up signal, which then wakes the battery. Because each of the two RF sensors within a battery needs to receive the magnetic field generated by its corresponding wake-up module to generate an induced EMF, a technician can only simultaneously contact both mapped positions of a battery with each wake-up module, thus preventing the accidental wake-up of other batteries when waking up one.

[0060] Please see Figure 6 , Figure 6 This is a schematic diagram of the battery outer packaging provided in an embodiment of this application. Figure 6 As shown, the first induction coil L1 and the second induction coil L2 are arranged diagonally at different heights. Furthermore, the first external packaging mapping position 601 and the second external packaging mapping position 602 are at different heights and located on different sides of the packaging box. The first external packaging mapping position 601 for generating an induced electromotive force in the first induction coil L1 and the second external packaging mapping position 602 for generating an induced electromotive force in the second induction coil L2 are marked on the outer packaging 60 of the battery BAT. The first and second external packaging mapping positions are respectively placed on two adjacent faces of the battery's outer packaging. A first perpendicular line is drawn from the first external packaging mapping position 601 to the edge where the two adjacent faces intersect, and a second perpendicular line is drawn from the second external packaging mapping position 602 to the edge where the two adjacent faces intersect. The intersection point of the first perpendicular line and the edge does not coincide with the intersection point of the second perpendicular line and the edge. Furthermore, the first wake-up coil L3, corresponding to the first induction coil, is close to the first external packaging mapping position 601, and the axis of the first wake-up coil is perpendicular to the first external packaging mapping position 601. At this time, the magnetic field generated by the first wake-up coil acts on the first induction coil, causing the first induction coil to generate an induced electromotive force. Similarly, the second wake-up coil L4, corresponding to the second induction coil, is close to the second external packaging mapping position 602, and the axis of the second wake-up coil is perpendicular to the second external packaging mapping position 602. At this time, the magnetic field generated by the second wake-up coil acts on the second induction coil, causing the second induction coil to generate an induced electromotive force. Moreover, the projection surfaces obtained by projecting the first wake-up coil and the first induction coil onto the first preset surface should at least overlap with the first external packaging mapping position, and the projection surfaces obtained by projecting the second wake-up coil and the second induction coil onto the second preset surface should at least overlap with the second external packaging mapping position. This ensures that when the wake-up coil is close to the induction coil outside the battery, the induction coil generates an induced electromotive force.

[0061] Furthermore, the sensing element used in this application is small in size and low in cost, having a minimal impact on the battery's size and manufacturing cost. Moreover, this application's solution does not increase the battery's additional power consumption; instead, it provides an AC signal and generates a magnetic field through an external wake-up module. This prevents the battery from being prematurely or being woken up in batches, reducing power consumption loss and increasing battery storage time. Additionally, it utilizes an induced electromotive force method to achieve non-contact battery wake-up, allowing maintenance without removing the battery's external packaging, facilitating battery maintenance during storage and transportation. The dual-sensor method avoids mutual interference between the two radio frequency sensing devices, requiring both devices to simultaneously sense the magnetic field and generate an induced electromotive force to wake the battery, preventing abnormal battery wake-up.

[0062] Based on the same application concept, this application also provides a wake-up device corresponding to the battery wake-up system provided in the above embodiments. Since the principle of the device in this application is similar to that of the battery wake-up system in the above embodiments of this application, the implementation of the device can refer to the implementation of the battery wake-up system, and the repeated parts will not be described again.

[0063] This application also provides a wake-up device, which is applied to a battery wake-up system as described in any of the above embodiments, wherein the wake-up device is the packaged wake-up module and is located outside the battery.

[0064] In other words, the wake-up module is independently packaged as a wake-up device, so that one battery corresponds to two independent wake-up devices, and neither device directly contacts the battery during the wake-up process. During battery application, since users need to unpack the battery before use, the battery can be woken up by a button, plugging in a charger, or connecting a load. Therefore, the wake-up device does not need to be provided to the user; it is only used to switch the battery out of transport mode to wake it up. Thus, the wake-up device only needs to be provided by battery maintenance technicians, avoiding additional costs for the user.

[0065] Based on the same application concept, this application also provides a battery corresponding to the battery wake-up system provided in the above embodiments. Since the principle of the battery in this application embodiment is similar to that of the battery wake-up system in the above embodiments of this application, the implementation of the battery can refer to the implementation of the battery wake-up system, and the repeated parts will not be described again.

[0066] This application embodiment also provides a battery, which is applied to a battery wake-up system as described in any of the above embodiments. The battery includes: a sensing module, including a radio frequency sensing device for responding to the AC signal and generating an induced electromotive force, wherein the sensing module generates a wake-up signal in response to the induced electromotive force of the radio frequency sensing device, wherein the number of wake-up modules is the same as the number of radio frequency sensing devices, and the wake-up modules and the radio frequency sensing devices correspond one-to-one; a power module, which provides a preset power supply in response to the wake-up signal; a battery management system, which exits the transport mode to wake up the battery when it receives electrical energy from the preset power supply; and a packaging shell, wherein the sensing module, the power module, and the battery management system are all disposed within the packaging shell.

[0067] In other words, the wake-up module is not installed inside the battery. Instead, the sensing module, power module, and battery management system (BMS) are housed within the battery package. Using the induced electromotive force (EMF) method, a passive sensing module is placed on the circuitry used to wake up the battery management system. When a certain power electromagnetic field is provided by the external wake-up module, the sensing module generates an induced EMF due to the electromagnetic field, thereby waking up the power module. The power module then wakes up the battery management system, thus waking up the battery.
