the power module 100 is provided with a first anti-theft port 110, the first anti-theft port 110 is provided with two short-circuit pins, and the two short-circuit pins are in short circuit in the port;
the energy storage battery module 200 is provided with a second anti-theft port 210 and a third anti-theft port 220, the second anti-theft port 210 and the third anti-theft port 220 are respectively provided with two short-circuit pins, the two short-circuit pins of the second anti-theft port 210 are in two-to-two short-circuit with the two short-circuit pins of the third anti-theft port 220, the two short-circuit pins of the second anti-theft port 210 are correspondingly connected with the two short-circuit pins of the first anti-theft port 110, and the two short-circuit pins of the third anti-theft port 220 are respectively connected with the two detection ends of the anti-theft DTU module 300;
the anti-theft DTU module 300 is configured to detect a connection state of the energy storage battery module 200, and when two detection end loops are disconnected, send alarm information to the background cloud server, so that the background cloud server sends the alarm information to the user terminal in time.
The first antitheft port 110, the second antitheft port 210 and the third antitheft port 230 are electric connector sockets or plugs, and are used for connecting lines seen by each module and transmitting electric signals.
Alternatively, the power supply module 100 may be a switched mode power supply (SwitchingModePowerSupply, SMPS).
Specifically, two short-circuit pins are respectively arranged on the three anti-theft ports, namely a first short-circuit pin and a second short-circuit pin. The two shorting pins of the second anti-theft port 210 and the two shorting pins of the third anti-theft port 220 are shorted in pairs to form two parallel shorting lines, and two connection schemes can be implemented. In the first scheme, the first shorting pin of the second anti-theft port 210 is connected with the first shorting pin of the third anti-theft port 220, and the second shorting pin of the second anti-theft port 210 is connected with the second shorting pin of the third anti-theft port 220.

The two shorting pins of the second anti-theft port 210 are correspondingly connected with the two shorting pins of the first anti-theft port 110, where the corresponding connection refers to one-to-one connection, and there may be two connection modes. The first type is that the first shorting pin of the second anti-theft port 210 is correspondingly connected to the first shorting pin of the first anti-theft port 110, and the second shorting pin of the second anti-theft port 210 is correspondingly connected to the second shorting pin of the first anti-theft port 110.

When the energy storage battery module 200 is normally in place, the two detection ends of the anti-theft detection circuit 320 form a short-circuited anti-theft loop through the connection of the three anti-theft ports when the two detection ends are seen from the power module 100. Once the energy storage battery module 200 is removed, the connection between the first antitheft port 110 and the second antitheft port 210 is disconnected, the connection between the second antitheft port 210 and the third antitheft port 220 is also disconnected, and the two detection ends of the antitheft DTU module 300 are disconnected, so that a loop cannot be formed. Based on this change, the anti-theft DTU module 300 detects the connection state of the energy storage battery module 200 and reports to the background cloud server.
In summary, in this embodiment, by setting the anti-theft ports on the power module 100 and the energy storage battery module 200 and constructing the short-circuited anti-theft loop, when the energy storage circuit module is stolen, the anti-theft loop is broken, and the broken condition is detected by the anti-theft DTU module 300 and reported to the background cloud server, so that the background cloud server and the user terminal can learn in time. Whether the energy storage battery module 200 is stolen or not is judged through the mechanical action of whether the anti-theft loop is disconnected, the principle is direct and simple, the influence of other factors such as communication faults among the modules or low-voltage dormancy of the battery is avoided, and the high reliability is realized.
In one embodiment, as shown in fig. 2, the number of energy storage battery modules 200 is at least two; the positions of the short-circuit pins on the first antitheft port 110, the second antitheft port 210 and the third antitheft port 220 are correspondingly arranged;
each energy storage battery module 200 is connected in series through a second anti-theft port 210 and a third anti-theft port 220 to form a series short circuit of the energy storage battery modules, wherein one end of the series short circuit is the second anti-theft port and the other end of the series short circuit is the third anti-theft port; the energy storage battery module series short circuit is connected with the first anti-theft port 110 of the power module 100 through the second anti-theft port 210 at one end, and the energy storage battery module series short circuit is respectively connected with the two detection ends of the anti-theft DTU module 300 through the two short-circuit pins of the third anti-theft port 220 at the other end.
Specifically, the positions of the shorting pins on the first antitheft port 110, the second antitheft port 210, and the third antitheft port 220 are correspondingly set, which means that the two shorting pins are set at the same position, that is, the first shorting pins on the first antitheft port 110, the second antitheft port 210, and the third antitheft port 220 are all set at the same position, and the second shorting pins on the first antitheft port 110, the second antitheft port 210, and the third antitheft port 220 are all set at the same position. When the first antitheft port 110 is connected with the second antitheft port 210, the first shorting pin of the first antitheft port 110 is connected with the first shorting pin of the second antitheft port 210, and the second shorting pin of the first antitheft port 110 is connected with the second shorting pin of the second antitheft port 210.

The second anti-theft port 210 of the first energy storage battery module 200 is connected with the first anti-theft port 110 of the battery module, and the third anti-theft port 220 is connected with the second anti-theft port 210 of the second energy storage battery module 200; the third anti-theft port 220 of the second energy storage battery module 200 is connected with the second anti-theft port 210 of the third energy storage battery module 200, and so on until the last energy storage battery module 200, the second anti-theft port 210 of the last energy storage battery module 200 is connected with the third anti-theft port 220 of the last energy storage battery module 200, and two shorting pins of the third anti-theft port 220 of the last energy storage battery module 200 are respectively connected with two detection ends of the anti-theft DTU module 300.
The energy storage battery module series short circuit is connected with the first anti-theft port 110 of the battery module through the second anti-theft port 210 at one end, so as to form an anti-theft loop. When one or more of the energy storage battery modules 200 are stolen, the anti-theft circuit is broken, so that anti-theft monitoring and timely alarming of the plurality of energy storage battery modules 200 are realized. The anti-theft alarm can be flexibly implemented in the case of one to a plurality of energy storage battery modules 200.
In one embodiment, as shown in fig. 4, the antitheft DTU module 300 includes: a fourth antitheft port 310, an antitheft detection circuit 320, a DTU processing unit 330, and a wireless communication unit 340;
two detection pins are arranged on the fourth anti-theft port 310, and the two detection pins are correspondingly arranged with the positions of the two short-circuit pins of the third anti-theft port 220; one end of the fourth anti-theft port 310 outside the port is connected with the third anti-theft port 220 of the energy storage battery module series short circuit, and the other end inside the port is connected with two anti-theft detection ends of the anti-theft detection circuit 320;
the anti-theft detection circuit 320 is connected with the DTU processing unit 330 and is used for detecting the connection state of each energy storage battery module 200, and sending an alarm signal to the DTU processing unit 330 when the two anti-theft detection end loops are disconnected;
the DTU processing unit 330 is connected to the wireless communication unit 340, and drives the wireless communication unit 340 to send alarm information to the background cloud server when receiving the alarm signal.
The fourth anti-theft port 310 is also an electrical connector socket or plug, and is used for connecting lines among modules and transmitting electrical signals. In a preferred embodiment, the first through fourth anti-theft ports are selected from the same class or model of electrical connector receptacles.
Specifically, the meaning of the corresponding arrangement of the positions of the port pins in the previous embodiment is the same, and the corresponding arrangement of the positions of the two detection pins of the fourth anti-theft port 310 and the two shorting pins of the third anti-theft port 220 means that the first shorting pin on the third anti-theft port 220 and the first detection pin on the fourth anti-theft port 310 are arranged at the same position, and the second shorting pin on the third anti-theft port 220 and the second detection pin on the fourth anti-theft port 310 are arranged at the same position. When the third anti-theft port 220 is connected to the fourth anti-theft port 310, the first shorting pin of the third anti-theft port 220 is connected to the first detection pin of the fourth anti-theft port 310, and the second shorting pin of the third anti-theft port 220 is connected to the second detection pin of the fourth anti-theft port 310.
The fourth anti-theft port 310 is connected to the third anti-theft port 220 of the last energy storage battery module 200 in the energy storage battery module series short circuit at one end outside the port, and forms a short-circuited anti-theft loop when seen from the fourth anti-theft port 310 to the power module 100. Therefore, when the anti-theft circuit is disconnected, the two detection pins of the fourth anti-theft port 310 and the two anti-theft detection terminals of the anti-theft detection circuit 320 are changed from the short circuit state to the open circuit state, and the anti-theft detection circuit 320 determines whether the energy storage battery module 200 is stolen according to the state of the anti-theft detection terminals. When the two anti-theft detection terminals are detected to be broken, an alarm signal is sent to the DTU processing unit 330.
Preferably, the DTU processor may be an MCU. The wireless communication unit 340 may be of a single communication system or a hybrid communication system, for example, a 4G communication system wireless communication unit 340 and a 4G/5G hybrid system wireless communication unit 340.
In one embodiment, as shown in fig. 5, the first antitheft port 110, the second antitheft port 210, the third antitheft port 220 and the fourth antitheft port 310 are further correspondingly provided with communication pins, and the communication pins of the fourth antitheft port 310 are connected with the DTU processing unit 330 in the ports;
the energy storage battery module 200 further includes a battery unit, a battery BMS control unit, and a communication encoding unit; in each energy storage battery module 200, the communication pin of the second anti-theft port 210 is respectively connected to the communication pin of the third anti-theft port 220 and the output end of the communication coding unit, and the battery BMS control unit is respectively connected to the input ends of the battery unit and the communication coding unit.

The battery unit can be provided with a plurality of batteries, and the plurality of batteries can be connected in parallel or in series.
Specifically, the communication pins of each module are used for outputting the state information of the module and receiving the control instruction of the background cloud server.

Resistor R1, resistor R2, resistor R3, resistor R4, resistor R5, resistor RPTC, triode Q1, triode Q2, diode D1, bidirectional voltage regulator ESD1 and capacitor C1
In this embodiment, the bi-directional voltage regulator ESD1 plays a role of ESD protection, and guides the ESD signal to GND to protect the whole circuit. The resistor RPTC plays a role in limiting current and prevents the port from being connected with high voltage by mistake, so that the ESD (electro-static discharge) is burnt out by excessive current. Diode D1 has unidirectional single pass characteristics and prevents high voltage from damaging transistor Q1. R1 and R2 are bias resistors of the triode Q1, and voltage division and current limitation are provided for EC conduction of the triode Q1. The transistor Q1 converts the mechanical characteristics of whether the anti-theft circuit is open or shorted into a weak current switching signal. The resistor R3 serves as a base current limiting resistor of the Q2 and plays a role in current limiting. The resistor R4 is a bypass resistor of the triode Q2, the triode Q1 is conducted when the circuit is broken, a loop is provided for releasing current of the capacitor C1, and the base electrode of the triode Q2 is pulled down. The capacitor C1 is a bypass capacitor of the transistor Q2, and can prevent false triggering caused by external interference. The transistor Q2 converts the electric signal of the transistor Q1 into a high-low level signal recognizable by the MCU (DTU processing unit 330). Resistor R5 is the pull-up resistor of MCU-I/O port.
