Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, not all, of the embodiments provided in the present application. All other embodiments that can be derived by a person skilled in the art from the embodiments given herein without making any creative effort shall fall within the protection scope of the present application.
Fig. 1 is a schematic structural diagram of a power supply device provided according to an embodiment of the present application. The power supply device 100 of fig. 1 includes: a battery pack 110 and an anti-theft device 120, wherein the battery pack 110 comprises at least one output end 111, at least one battery cell 112, a circuit switch 113 and a control unit 114. The at least one battery cell 112 is connected to the output end 111 via the circuit switch 113.
The control unit can control the on-off of the circuit switch to enable the circuit between the at least one battery cell and the output end to be connected or the circuit between the at least one battery cell and the output end to be disconnected. The circuit switch may include two states, state a and state B, in which when the circuit switch is in state a, the circuit between the at least one battery cell and the output terminal is connected, and the power supply apparatus 100 can provide power through the output terminal; when the circuit switch is in the state B, the circuit between the at least one battery cell and the output terminal is broken, and the power supply device 100 cannot provide power through the output terminal. The state a may be a closed state of the circuit switch, the state B may be an open state of the circuit switch, and both the state a and the state B may be closed states of the circuit switch (for example, a single-pole double-throw switch), which is not limited in this application.
In a specific implementation, the control unit and the circuit switch may be separate physical devices, or may be implemented by one physical device, such as an electromagnetic relay, a sensor, and the like, but the application is not limited thereto.
The control unit may control the circuit switch to be switched to the state a according to the detected first signal sent by the anti-theft device, or, when the original state of the circuit switch is the state a, the control unit may keep the circuit switch in the state a or keep the control unit not operating the circuit switch, that is, connect the at least one electrical core and the output terminal, and the power supply device 100 may provide power through the output terminal; the control unit controls the circuit switch to the state B when the control unit does not detect the first signal sent by the anti-theft device within a first time interval, or the control unit may keep the circuit switch in the state B or keep the control unit not operating the circuit switch when the original state of the circuit switch is the state B, that is, the circuit between the at least one battery cell and the output terminal is disconnected, and the power supply device 100 cannot provide power through the output terminal. The anti-theft device may periodically transmit the first signal, the first time interval being greater than or equal to a transmission period of the first signal.
In one embodiment, the initial state of the circuit switch in the power supply device is state B, for example, the circuit switch is in state B at the time of factory shipment or the circuit switch is switched to state B at the time of installation. In case the power supply device is required to provide power, the circuit switch switches to state a and the anti-theft device periodically sends a first signal so that the power supply device can provide power through the output. When the state of the circuit switch is kept in the state A, the anti-theft device periodically transmits the first signal, so that the control unit can judge the state of the power supply device according to the first signal.
Alternatively, the control unit may control the circuit switch to the state a when detecting the first signal sent by the anti-theft device, or other signals may instruct the control unit to control the circuit switch to the state a, or other ways to switch the circuit switch to the state a, which is not limited in this application.
When the control unit does not detect the first signal within a first time interval, the control unit controls the state of the circuit switch to be transferred to the state B, so that the power supply device can not provide power through the output end.
For example, the power supply may be a backup power supply of a base station in the mobile communication network or may also be referred to as a backup battery. When the power supply device is not started to supply power, the circuit switch keeps the state B, so that the power supply device cannot supply power outwards, the probability of stealing the power supply device can be reduced, and a thief finds that the battery cannot supply power, the utilization value is low, and stealing action cannot be taken. When the standby power supply device is started to provide power, namely the circuit switch is switched to the state A, the anti-theft device periodically sends a first signal, the control unit detects the first signal to judge whether the power supply device is stolen, and when the control unit does not detect the first signal within a first time interval, the control unit controls the circuit switch to be switched to the state B, so that the power supply device cannot provide power outwards. The power supply device can not provide value for a thief after being stolen, and if the power supply device is recovered, the loss caused by being stolen can be reduced because the power supply device is not used.
In another embodiment, the initial state of the circuit switch in the power supply device is state a, the anti-theft device periodically transmits the first signal, and the control unit does not perform any operation on the circuit switch, i.e., does not change the state of the circuit switch, and maintains state a of the circuit switch in the case that the control unit can detect the first signal in the first time interval. When the control unit does not detect the first signal within a first time interval, the control unit controls the state of the circuit switch to be transferred to the state B, so that the power supply device can not provide power through the output end.
The control unit does not detect the first signal within a first time interval, the control unit cannot detect the first signal due to the fact that the connection between the battery pack and the anti-theft device is cut off, or the connection between the anti-theft device and the external equipment is cut off, the anti-theft device stops sending the first signal, and the control unit cannot detect the first signal.
In one embodiment, the anti-theft device detects a second signal transmitted by the external device, and stops transmitting the first signal if the second signal is not detected within a second time interval, which may be a periodic signal, the second time interval being greater than or equal to a transmission period of the second signal. Optionally, the anti-theft device sends a third signal for instructing the control unit to control the circuit switch to the state B in case the second signal is not detected within a second time interval. When the control unit detects the third signal, the control circuit switch is switched to the state B, so that the power supply device cannot provide power to the outside.
According to the scheme of the application, the power supply device can not supply power to the outside under the condition of not being started, so that the probability that the power supply device is stolen can be reduced. After the power supply device is stolen, the control unit can control the circuit switch to prevent the power supply device from supplying power outwards, so that the value of a thief caused by the power supply device after being stolen can be weakened, the situation that a battery is stolen in future can be prevented, and when the power supply device is stolen and recovered, the power supply device is not used, so that the loss caused by the theft can be reduced.
In this application, the first signal, the second signal or the third signal may be a wired signal transmitted through a connection line between the signal transmitting end and the signal receiving end, or may also be a wireless signal between the signal transmitting end and the signal receiving end, for example, the second signal transmitted by the external device is a wireless signal, and the anti-theft device also has a function of processing the wireless signal, which is not limited in this application.
By way of example and not limitation, the first signal and/or the third signal include first identification information for the control unit to identify the anti-theft device. That is, the control unit and the anti-theft device are matched, or the battery pack and the anti-theft device are matched. The first identification information can uniquely identify the anti-theft device matched with the control unit, and signals transmitted by other anti-theft devices or other signals cannot enable the control unit to control the opening and closing of the circuit switch. The power supply device can be prevented from supplying power through a forged signal after being stolen. Alternatively, the signal including the first identification information can trigger the control unit to control the circuit switch to be opened or closed, that is, the first identification information is the only identification information that the control unit controls the circuit switch to be opened or closed.
By way of example and not limitation, the second signal includes second identification information for the anti-theft device to identify the external device. That is, the anti-theft device and the external device are matched. The second identification information can uniquely identify the external device matching the antitheft apparatus.
The identification information (the first identification information or the second identification information) may be a period length of the signal (the first signal, the third signal or the second signal), a waveform of the signal, or bit information carried in the signal. The first identification information or the second identification information may be set by a user or may be set by the power supply apparatus 100 at the time of factory shipment, but the present application is not limited thereto.
The signal includes identification information specific to the power supply device, and even if another signal is input to the control unit after the power supply device 100 is stolen, or another anti-theft device that transmits a signal is connected to the control unit, the control unit control circuit switch cannot be switched to the state a. On the other hand, inputting a second signal that does not include the second identification information to the anti-theft device does not trigger the anti-theft device to transmit the first signal. The power supply device can be weakened to bring value to thieves after being stolen.
For example, the first identification information is a waveform of a first signal, the power supply device 100 sets the first signal transmitted by the antitheft device in the power supply device 100 as the signal of the first waveform at the time of factory shipment, and the control unit of the power supply device 100 controls the circuit switch to be in the state a only when the signal of the first waveform is detected. For example, the first waveform may be a waveform including three short pulses within one period, or the first waveform may be a waveform having a specified frequency, but the present application is not limited thereto. After the power supply device is stolen, even if a signal with other waveform is input to the control unit or the control unit is connected with other anti-theft devices, the control unit cannot control the opening and closing of the circuit switch so that the power supply device can supply power.
For another example, the second identification information may be a period length of the second signal, the second signal with the period X may be set at the time of factory shipment of the power supply device 100 to trigger the anti-theft device to transmit the first signal, and the anti-theft device keeps transmitting the first signal only when the anti-theft device can detect the second signal with the period X within one second time interval. The anti-theft device which cannot be triggered by other signals transmits the first signal. Thus, even if another signal is input to the antitheft device after the power supply device is stolen, the antitheft device cannot be triggered to transmit the first signal, and the power supply apparatus cannot supply power.
As an example and not by way of limitation, the anti-theft device may be a Battery Management System (BMS), and the external device may be a network management device, but the present application is not limited thereto.
In one embodiment, a battery pack in a power supply apparatus may include at least one prosthetic core, such as shown in fig. 2. The false body core is packaged with at least one battery core in the battery pack and comprises a positive pole column, a negative pole column and a shell. The circuit switch and the control unit are arranged in at least one prosthesis core, wherein two ends of the circuit switch and/or the control unit are respectively connected with a positive pole column and a negative pole column of the prosthesis core. The circuit switch and the control unit may be built in the same prosthesis core, as shown in fig. 3, or may be separately built in different prosthesis cores, which is not limited in the present application.
According to the scheme, the circuit switch and/or the control unit are/is encapsulated in the same outer part as the battery cell, so that the concealment of the circuit switch and the control unit can be improved, and the circuit switch and/or the control unit cannot be stolen easily.
