Referring to
When a startup of the personal mobility 1 is turned on, the controller 200 may measure a first voltage applied to the first switch S1 between the first test voltage source VS1 and the ground G and a second voltage applied to the second switch S2 between the second test voltage source VS2 and the ground G through the first sensor 100. The controller 200 may assign the user to one of a plurality of predetermined groups based on the weight information obtained through the second sensor 300, and compare the first voltage and the second voltage with a reference value previously allocated to a group to which the user is assigned. When at least one of the first voltage or the second voltage corresponds to a reference value or more, the controller 200 may control the alarm device 500 to provide a warning alarm to the user.
The alarm device 500 may include a display, and may also include various devices configured for providing an alarm to a user 2. The first test voltage source VS1 and the second test voltage source VS2 may refer to devices that pass a current to identify whether there is a short circuit. The first test voltage source VS1 may receive a power from the battery B, and may refer to a device which is separately present and transmits the current.
A first resistance R1 and a second resistance R2 may refer to a resistance located between the first test voltage source VS1 and a main body of the personal mobility 1 that a body of the user 2 contacts with. In the instant case, the first resistance R1 and the second resistance R2 are virtual resistances, and may refer to virtual resistances which may occur when a leakage current occurs.
The first resistance R1 and the second resistance R2 are virtually existing resistances that are connected in parallel to the first switch S1 and the second switch S2, respectively, when the leakage current occurs. This may refer to the virtual resistance for measuring a voltage measured by the occurrence of the leakage current in the switch S1 and the second switch S2. The first resistance R1 may refer to a resistance for identifying a current between the positive (+) electrode of the battery B and the main body of the personal mobility 1 by connecting with the positive (+) electrode of the battery B. The second resistance R2 may refer to a resistance for identifying a current between the negative (−) electrode of the battery B and the main body of the personal mobility 1 by connecting with the negative (−) electrode of the battery B. The first resistance R1 and the second resistance R2 may refer to virtual insulation resistances to express an insulation resistance between a chassis and the battery B in a circuit. The first resistance R1 and the second resistance R2 may refer to resistances for measuring the insulation resistance between the main body of the personal mobility 1 in which the positive electrode of the battery B and the body of the user 2 are in contact and the main body of the personal mobility 1 in which the negative electrode of the battery B and the body of the user 2 are in contact.
The first sensor 100 may detect the outputs of the first test voltage source VS1 and the second test voltage source VS2. At the instant time, the first sensor 100 may measure a voltage applied to all resistances in the detection circuit. The ground G may refer to a ground.
The detection circuit may refer to a circuit necessary to identify whether there is the short circuit. The detection circuit may include the third switch S3, the fourth switch S4, the first switch S1, the second switch S2, the fifth switch S5, and the sixth switch S6. The second sensor 300 may include a pressure sensor that detects a pressure.
The second sensor 300 may be located in the main body of the personal mobility 1, and the position may not be limited to the main body. The predetermined plurality of groups may be divided into an adult group and a child group. At the instant time, it is possible to subdivide the group by subdividing the group rather than the two groups of adults and children. When it is divided into the adult group and the child group, the weight may be measured through the second sensor 300, and those above a certain weight may be assigned as the adults and those below the certain weight may be assigned as the children. As will be described later, it may be divided into the adult group and the child group through a user authentication device as well as the second sensor. The pre-allocated reference value may refer to a value which is a pre-allocated reference value to each of a plurality of predetermined groups. For example, when it is divided into the adult group and the child group, the children may be more susceptible to the leakage current. Therefore, for safety, it is necessary to set the reference value low for the children, and for the adults, it may be safe even if the reference value is set relatively higher than for the children. Therefore, it is necessary to set different reference value for the group classified as the adults and the group classified as the children. Thereafter, the first voltage and the second voltage are compared with the reference value, and if at least one of the first voltage or the second voltage is greater than the reference value, it may be determined as the short circuit. A reference for determining the reference value is that in a case of the positive (+) electrode of the battery B, only the third switch S3 is closed and the voltage applied to the first switch S1 is measured. Thereafter, the third switch S3 and the first switch S1 are closed and the voltage applied to the first switch S1 is measured, compared, and then set. In a case of the negative (−) electrode of the battery B, only the fourth switch S4 is closed and the voltage applied to the second switch S2 is measured. Thereafter, the fourth switch S4 and the second switch S2 are closed and the voltage applied to the second switch S2 is measured, compared, and then set. A method of measuring the first voltage and the second voltage will be described in detail later.
When it is determined that there is the short circuit, the warning alarm may be provided through the alarm device 500. Closing the switch may mean allowing the current to be connected through the switch, as opposed to opening the switch. Also closing the switch may refer to shorting the switch. Looking particularly, the detection circuit may include the third switch S3, the fourth switch S4, the first switch S1, the second switch S2, the fifth switch S5, the sixth switch S6, the first resistance R1, the second resistance R2, a third resistance R3, a fourth resistance R4, the first test voltage source VS1, the second test voltage source VS2, the ground G, and the battery B. The third switch S3 may be located between the first test voltage source VS1 and the third resistance R3, and the fifth switch S5 may be located between the third resistance R3 and the positive (+) electrode of the battery B. The first resistance R1 and the fourth switch S4 may be connected in parallel between the fifth switch S5 and the ground G. The second switch S2 may be located between the second test voltage source VS2 and the fourth resistance R4, and the sixth switch S6 may be located between the negative (−) electrode of the battery B and the fourth resistance R4, and the second resistance R2 and the first switch S1 may be connected in parallel between the ground G and the sixth switch S6. When the first voltage and the second voltage come out higher than the reference value, the user 2 may be alerted through the alarm device 500, and furthermore, a warning signal may be transmitted to a management server 600 through a communicator 700.
The management server 600 may receive the warning signal from the personal mobility 1. The management server 600 may refer to a server that an administrator in charge of managing the personal mobility 1 may refer to, and may refer to a server that collects information related to the personal mobility 1. when an operation of the personal mobility 1 is restricted, a main contactor may be opened in a Battery Management System (BMS), and the administrator of the personal mobility 1 may be alerted that the insulation resistance has broken, and then repaired may be induced. Furthermore, when the personal mobility 1 stops for a predetermined time period or more while driving, the controller 200 may provide the warning alarm to the user 2 when at least one of the first voltage or the second voltage corresponds to the reference value or more. For example, if the user 2 is taking a rest for the predetermined time period while driving the personal mobility 1, it may be determined that the user 2 is taking a break or waiting. In the instant case, it is possible to check whether there is the leakage current again for the safety. The operation of determining whether there is the leakage current is as described above. The communicator may transmit the warning signal to the management server.
