[0016] With the development of science and technology, the design requirements for vehicle batteries are getting higher and higher. Among them, the detection of vehicle battery abnormalities is a very important part of the vehicle battery design requirements. In related technologies, users directly check whether the vehicle battery is still installed in the vehicle to detect whether the vehicle battery is abnormal, but this inspection method has a high time cost and low detection efficiency.

[0017] The following specific embodiments are used to describe in detail the technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0018] Figure 1 The present invention provides a schematic diagram of the structure of a vehicle-mounted battery detection device provided by an exemplary embodiment of the present invention, which can be applied to electric vehicles, automobiles, and other devices equipped with batteries. The vehicle-mounted battery detection device 10 includes a battery pack 101 for powering a vehicle-mounted terminal 20, and a control module 102 connected to the battery pack 101 for determining whether the battery pack 101 is disconnected from the vehicle-mounted terminal 20.

[0019] If the control module 102 detects that the battery pack 101 and the vehicle terminal 20 are disconnected during the process of the battery pack 101 supplying power to the vehicle terminal 20 , it is determined that an abnormality exists in the battery pack 101 .

[0020] In some embodiments, taking a tram as an example, an on-board terminal and an on-board battery detection device are installed in the tram, such as Figure 2 As shown, during the normal power supply process of the battery pack 101 for the vehicle-mounted terminal 20, the user end can check the connection status of the battery pack 101 in the electric car 30 and the vehicle-mounted terminal 20 at any time. If the battery pack 101 can no longer normally supply power to the vehicle-mounted terminal 20, the battery pack 101 and the vehicle-mounted terminal 20 are disconnected, and it is determined that there is an abnormality in the battery pack 101 at this time.

[0021] In some embodiments, the vehicle-mounted battery detection device also includes a positioning module connected to the battery pack, and the positioning module is used to obtain the current position information of the battery pack 101 and the path information of the battery pack 101 being moved when it is determined that there is an abnormality in the battery pack 101, and send the position information and the path information to the user end.

[0022] In some embodiments, an abnormality in the battery pack 101 means that the battery pack is disconnected from the vehicle-mounted terminal 20 and the distance from the vehicle-mounted terminal 20 changes all the time. Therefore, in order to ensure the safety of the battery pack 101, the positioning module is used to obtain the current position information of the battery pack 101 and the path information of the battery pack 101 being moved when it is determined that there is an abnormality in the battery pack 101, and send the position information and the path information to the user end, so that the user can always grasp the position of the battery pack 101 through the user end, and can find the battery pack 101 according to the path information.

[0023] The positioning module is further provided with a wireless transmission module. After obtaining the current position information of the battery pack 101 and the path information of the battery pack 101 being moved, the position information and the path information are sent to the user end through the wireless transmission module.

[0024] In some embodiments, after the control module 102 detects that the battery pack 101 and the vehicle-mounted terminal 20 are disconnected, the control module 102 is further used to: detect whether a button on the battery pack 101 has been pressed within a first preset time period before the current moment, and if so, determine that the battery pack 101 is normal.

[0025] Specifically, when the battery pack 101 and the vehicle-mounted terminal 20 are disconnected, there may be no abnormality in the battery pack 101, because in actual operation, the relevant technicians remove the vehicle-mounted battery detection device by triggering the button on the battery pack 101. Therefore, after the control module 101 detects that the battery pack 101 and the vehicle-mounted terminal 20 are disconnected, it is also necessary to detect whether the button on the battery pack 101 is pressed. If it is pressed within a first preset time period before the current moment, it is determined that the battery pack 101 is normal.

[0026] In some embodiments, after the control module 102 detects that the battery pack 101 and the vehicle terminal 20 are disconnected, the control module 102 is further used to: determine that the battery pack 101 is normal if a confirmation message sent by the user terminal is received within a second preset time period before the current moment.

[0027] Specifically, when the battery pack 101 and the vehicle-mounted terminal 20 are disconnected, there may be no abnormality in the battery pack 101, because in actual operation, the relevant technicians send confirmation information through the user terminal to manipulate the switch on the battery pack 101 to remove the vehicle-mounted battery detection device. Therefore, after the control module 101 detects that the battery pack 101 and the vehicle-mounted terminal 20 are disconnected, it is also necessary to detect whether the confirmation information sent by the user terminal is received within the second preset time period before the current moment. If so, it is determined that the battery pack 101 is normal.

[0028] In some embodiments, the control module 102 is further used to: if it is detected that the voltage at the interface where the battery pack 101 and the vehicle terminal 20 are connected is zero, determine that the battery pack 101 and the vehicle terminal 20 are disconnected.

[0029] In some embodiments, the device also includes a backup power supply.

[0030] The control module 102 is further configured to: start the backup power supply to supply power to the vehicle-mounted battery device when the voltage at the interface where the battery pack 101 is connected to the vehicle-mounted terminal 20 is zero. The control module 12 is further configured to: determine that the battery pack is abnormal if it is detected that the vehicle-mounted terminal and the battery pack are disconnected.

[0031] Specifically, the control module 102 is also used to automatically start the backup power supply to power the various components in the vehicle-mounted battery detection device during actual operation in order to ensure that the various components in the vehicle-mounted battery detection device can be used normally when it is detected that the voltage at the interface connecting the battery pack 101 and the vehicle-mounted terminal 20 is zero.

[0032] In some embodiments, the device also includes a flash light; the control module 102 is also used to: control the flash light to flash when it is detected that the battery pack 101 and the vehicle-mounted terminal 20 are disconnected.

[0033] In some embodiments, the control module 102 is further used to: after the battery pack 101 and the vehicle-mounted terminal 20 are disconnected, when a flashing instruction sent by a user terminal is detected, control the flashing light to flash.

[0034] Specifically, when the battery pack 101 is disconnected from the vehicle-mounted terminal 20 , in order to ensure the safety of the battery pack, during actual operation, relevant technicians send a flashing light command through a user terminal to control the flashing light in the device.

[0035] In some embodiments, the device further includes a buzzer; the control module 102 is further configured to control the buzzer to sound an alarm when it is detected that the battery pack 101 and the vehicle-mounted terminal 20 are disconnected.

[0036] In some embodiments, the control module 102 is further used to: after the battery pack 101 and the vehicle-mounted terminal 20 are disconnected, when an alarm prompt tone playing instruction sent by a user terminal is detected, control the buzzer to alarm.

[0037] Specifically, when the battery pack 101 is disconnected from the vehicle-mounted terminal 20 , in order to ensure the safety of the battery pack, during actual operation, relevant technicians send an alarm prompt tone play instruction through the user terminal to control the buzzer alarm in the device.

[0038] The technical solution provided by the present disclosure includes a battery pack for powering a vehicle terminal, and a control module connected to the battery pack for determining whether the battery pack is disconnected from the vehicle terminal; if the control module detects that the battery pack is disconnected from the vehicle terminal during the process of the battery pack powering the vehicle terminal, it is determined that the battery pack is abnormal. By detecting that the battery pack is disconnected from the vehicle terminal by the control module, it is determined that the battery pack is abnormal, which can achieve the function of real-time detection of the connection status between the battery pack and the vehicle terminal, and reduce time cost and greatly improve detection efficiency.
