Whether the battery of the electric vehicle is stolen or not can be found in time, so that the risk of stealing the battery of the electric vehicle is effectively reduced. The following describes implementation details of the anti-theft system for an electric vehicle battery according to the present embodiment in detail, and the following description is provided only for the sake of understanding and is not necessary for implementing the present embodiment.
The anti-theft tag 101 is arranged on a battery of the electric vehicle and used for detecting data information of the battery and judging whether the data information is abnormal or not, and if so, the data information is marked as stolen information; the data information comprises a change value of voltage between the anode and the cathode of the battery and a change value of acceleration of the battery. Specifically, in practical application, the data can be marked as stolen information when the data is abnormal; and under the condition that the data is normal, the data information can be marked as normal information, so that the server can distinguish the data information conveniently. The running state of the electric vehicle, whether it is in a stationary state or in a running state, or in a coasting state, can be determined based on the acceleration change value of the battery.
In actual practice, the following situations may be encountered: in the first situation, when the voltage of a battery of the electric vehicle changes, the battery posture is detected through the acceleration of a battery, if the battery posture is not changed, the electric vehicle is in a static state, the electric vehicle is currently charged, and the state is a normal state; in the second situation, when the voltage of the battery of the electric vehicle changes, if the posture of the battery changes, namely the electric vehicle is in a running state, the current state is also a normal state. In the third situation, when the voltage of the battery of the electric vehicle is not changed, the attitude of the battery is detected through the acceleration of the battery, if the attitude of the battery is changed, the state of the electric vehicle before the current moment is detected, and if the state before the electric vehicle is a driving state, the state is sliding, namely the moment is in a normal state; if the electric vehicle is in a static state in the previous state and is in a motion state at the moment, the storage battery of the electric vehicle is stolen, and the data information is marked as stolen information. In another case, when the voltage of the battery of the electric vehicle is not changed, the posture of the battery is not changed, and the battery is in a static state, which is a normal state.
And the radar 102 is used for acquiring the mark of the data information and sending the mark of the data information to the server 103 after the battery enters the radiation range of the radar 102.
Specifically, the radar 102 is usually disposed at the roadside, and there is a radar at intervals, and since the security tag 101 is attached to the battery, the security tag 101 and the radar 102 can perform data communication by using the radio frequency identification technology. The radar 102 transmits an electromagnetic wave signal, and the electromagnetic wave signal is returned to the radar receiver after encountering the anti-theft tag 101, the carried target information can be understood as a mark for the radar 102 to acquire data information, the radar 102 can also acquire the data information, the data information comprises a mark for identifying the data information, the mark can be a mark for displaying normal data, and the mark can also be a stolen mark for displaying abnormal data. Or, after receiving the electromagnetic wave signal emitted by the radar 102, the security tag 101 enters the radiation range of the radar 102, and the security tag 101 sends data information to the radar 102. Contactless information transmission can be realized through the radio frequency identification technology, the operation and control are easy, the flexibility is higher, the identification speed is high, the anti-theft tag 101 can be identified as long as the anti-theft tag enters the radiation range of the radar 102, and the rapid and effective acquisition of the data information of the battery by the radar 102 is facilitated.

And the server 103 is used for sending alarm information after judging that the electric vehicle is stolen according to the mark of the data information. If the received data information with the mark indicating that the battery is stolen is received, the electric vehicle is judged to be stolen, and alarm information is sent. The alarm information can be sent to a public security department and also can be sent to the electric vehicle owner, so that related personnel can obtain the alarm information of the electric vehicle theft in time and take corresponding measures. The alarm information that server 103 sent can also carry radar 102's positional information, radar 102 can send the positional information of radar to server 103 after the battery gets into radar 102's radiation range, and the position of electric motor car battery is tracked to the positional information that carried in the alarm information that police department or electric vehicle owner can send according to server 103 to in time retrieve stolen electric motor car battery, improved the possibility of tracking stolen battery according to the positional information of radar greatly.

The steps are a judgment, the same data are cleared after the judgment is finished, the data are supplemented to 100 groups according to the time sequence, and the judgment steps are continued for 40 times. After the judging step is completed for 40 times, counting the count that the battery state is static and the count that the voltage state is stable, if the count that the battery state is static is more than 20, marking the state of the battery as unchanged, otherwise marking the state of the battery as changed; if the voltage status is stable, the count is greater than 25, the voltage of the battery is marked as unchanged, otherwise, the voltage is marked as changed, and if the voltage drop is 0.1V or the voltage of the battery is marked as changed, the voltage status is not stable. When the state mark of the battery is changed and the voltage state is a stable state, the battery is judged to be stolen.
