[0050] A control panel (13) may be provided for communication between the battery exchange system (1) and a user. According to an embodiment, the control panel (13) may be an input / output device that receives a request from a user and outputs information. According to an embodiment, the control panel (13) may be a device capable of both input and output (e.g., a touch screen display). According to an embodiment, the control panel (13) may include an input device (e.g., a keyboard, a card reader, a scanner, a camera, etc.) or an output device (e.g., a display, a speaker, a video card, an audio card, a printer, or other external devices).

[0051] An integrated controller (14) can control a plurality of battery exchange devices (11-1, 11-2, ..., 11-n), a power source (12), and a control panel (13). The integrated controller (14) can control the operation of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n) to manage the use of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n).

[0052] According to an embodiment, the integrated controller (14) can manage the battery charging operation of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n). According to an embodiment, the integrated controller (14) can control each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n) to start battery charging and control to stop charging.

[0053] According to an embodiment, the integrated controller (14) can manage the insulation status of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n). To manage the insulation status, the integrated controller (14) can measure the insulation resistance of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n). In addition, the integrated controller (14) can determine the insulation status of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n) based on the measured insulation resistance. The integrated controller (14) can determine the insulation status as a normal insulation status or an insulation breakdown status.

[0054] According to an embodiment, the integrated controller (14) can manage the use of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n) based on the insulation status of each of the determined plurality of battery exchange devices (11-1, 11-2, ..., 11-n). In addition, the integrated controller (14) can determine whether maintenance is required for each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n) based on the insulation status.

[0055] In addition to the above-described disclosure, the integrated controller (14) can control the overall operation of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n). For example, the integrated controller (14) can open or close the doors of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n).

[0056] Additionally, the integrated controller (14) can communicate with a server (not shown) or other control module located outside the battery exchange system (1) via wires or wirelessly.

[0057] According to an embodiment, the operation of the integrated controller (14) can be described as follows. When a battery insertion request is input from a user to the control panel (13), the integrated controller (14) can check whether there is a battery exchange device that does not accept a battery among a plurality of battery exchange devices (11-1, 11-2, ..., 11-n). When a battery exchange device that does not accept a battery (e.g., 11-1, 11-2, and 11-3) is determined, the integrated controller (14) can determine the insulation status of the battery exchange devices (11-1, 11-2, and 11-3). The integrated controller (14) can select one or more of the battery exchange devices (e.g., 11-1 and 11-2) that are determined to be in a normal insulation status among the battery exchange devices (11-1, 11-2, and 11-3) that do not accept a battery. For example, if the integrated controller (14) selects the battery exchange device (11-1), the integrated controller (14) can open the door of the battery exchange device (11-1). After a battery is received in the slot of the opened battery exchange device (11-1), the integrated controller (14) can close the door of the battery exchange device (11-1) and charge the received battery.

[0058] As described above, since the integrated controller (14) controls the operation of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n) and measures insulation resistance to manage use, the battery exchange system (1) can independently evaluate the safety of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n). In addition, the battery exchange system (1) can maintain the battery exchange system (1) and ensure the safety of the user by managing each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n).

[0059] According to an embodiment, the power line (111) and the ground line (112) are configured to transmit power of the power source (12) to components within the battery exchange system (1) that consume power. For example, the power of the power source (12) may be transmitted to a plurality of battery exchange devices (11-1, 11-2, ..., 11-n) via the power line (111). The ground line (112) may be a reference line that generates a potential difference with respect to the power line (111).

[0060] According to an embodiment, the power line (111) may have a different voltage than the ground line (112). For example, the voltage of the power line (111) may be higher than the voltage of the ground line (112). In addition, the power line (111) and the ground line (112) within the battery exchange system (1) may not be grounded but may be in a floating state. Accordingly, the voltages of both the power line (111) and the ground line (112) may be different from the ground voltage of the power supply of the battery exchange system (1) (the chassis ground voltage of the battery exchange system (1)).

[0061] The communication line (113) is configured to enable communication between different components of the battery exchange system (1). According to an embodiment, a plurality of battery exchange devices (11-1, 11-2, ..., 11-n) and a control panel (13) can communicate with an integrated controller (14) via the communication line (113).

[0062] According to an embodiment, various types of control commands may be transmitted through the communication line (113). The control commands that may be transmitted through the communication line (113) may include user requests and electrical signals between internal components of the battery exchange system (1).

[0063] According to the embodiment of FIG. 1, the communication line (113) is illustrated as a wired communication line, but according to another embodiment, the communication line (113) may be configured wirelessly.

[0064] Hereinafter, a battery exchange device (11-1) will be described with reference to FIGS. 2 and 3.

The controller (104) can control the power switch (102) and the measurement unit (103) to measure the insulation resistance of at least one of the power line (111) and the ground line (112). According to an embodiment, the controller (104) can control the power switch (102) to be opened before measuring the insulation resistance. The insulation resistance measurement will be described with reference to FIGS. 3 and 4 below.

[0074] The controller (104) can determine the insulation status of the battery exchange device (11-1) based on the insulation resistance measured by the measuring unit (103). For example, the controller (104) can determine the insulation status of the power line (111) and / or the ground line (112) based on the measured insulation resistance of the power line (111) and / or the ground line (112). Through this, the controller (104) can manage the status of the battery exchange device (11-1).

[0075] According to an embodiment, if the controller (104) determines that the power line (111) is in an insulation breakdown state, the controller may request maintenance of the battery exchange device (11-1) to a higher controller (e.g., an integrated controller (14)). According to an embodiment, if the controller (104) determines that either the power line (111) or the ground line (112) is in an insulation breakdown state, the controller (104) may request maintenance of the battery exchange device (11-1) to a higher controller (e.g., an integrated controller (14)). Accordingly, the controller (104) may measure the insulation resistance of the power line (111) or the ground line (112) to manage the battery exchange device (11-1).

[0076] The controller (104) can transmit the determined insulation status of the battery exchange device (11-1) to the integrated controller (14). Based on the insulation status of the battery exchange device (11-1) transmitted from the controller (104), the integrated controller (14) can determine whether the battery exchange device (11-1) can be used for battery exchange. In addition, the integrated controller (14) can determine whether maintenance of the battery exchange device (11-1) is required based on the insulation status of the battery exchange device (11-1).

[0077] Through the controller (104) and the integrated controller (14), the battery exchange system (1) can independently evaluate the safety of the battery exchange device (11-1). In addition, the battery exchange system (1) can ensure the safety of users of the battery exchange device (11-1) and efficiently maintain the battery exchange device (11-1).

[0078] The controller (104) can be connected wirelessly or wiredly to components within the battery exchange system (1). The controller (104) can be connected to the integrated controller (14), the connection unit (101), the power switch (102), and the measurement unit (103) via a communication line (113).

[0080] Referring to FIG. 3, the voltage / current measurement unit (121) can apply voltage or current to the battery exchange device (11-1) to measure the insulation resistance of the battery exchange device (11-1). In addition, the voltage / current measurement unit (121) can measure the current flowing in the battery exchange device (11-1) or the voltage of the battery exchange device (11-1) based on the voltage or current applied to the battery exchange device (11-1). Therefore, the voltage / current measurement unit (121) can calculate the insulation resistance of the battery exchange device (11-1) based on the measured voltage or current.

[0081] According to an embodiment, the voltage / current measuring unit (121) can measure the AC current flowing in the battery exchange device (11-1) or the AC voltage of the battery exchange device (11-1) based on the AC voltage or AC current applied to the battery exchange device (11-1).

[0087] The controller (104) can open the power switch (102) before measuring the insulation resistance of the battery exchange device (11-1). As the switch (S0) is opened by the controller (104), the electrical connection between the power source (12) and the connection part (101) can be cut off. That is, as the power switch (S0) is opened before measuring the insulation resistance, the power supplied from the power source (12) to the connection part (101) can be cut off. Accordingly, the battery can be electrically separated from the measurement part (103) before measuring the insulation resistance. This allows for accurate measurement of the insulation resistance of the battery exchange device (11-1). In addition, even when the battery is connected to the connection part (101), the electrical connection can be cut off by opening the power switch (S0), so that the insulation resistance can be measured only by controlling the power switch (102) without physically removing the battery. Through this, the safety of the battery exchange device (11-1) can be evaluated, and the battery exchange device (11-1) can be maintained efficiently.

[0088] The power line (111) may be placed between the voltage / current measuring unit (121) and the first connection terminal (P1) of the connection unit (101). According to an embodiment, the power line (111) may be electrically connected to the first pole of the battery.

[0089] A ground line (112) may be placed between the voltage / current measuring unit (121) and the second connection terminal (P2) of the connection unit (101). According to an embodiment, the ground line (112) may be electrically connected to the second pole of the battery.

[0090] According to an embodiment, the power line (111) and the ground line (112) may have different voltages. Also, according to an embodiment, both the power line (111) and the ground line (112) may have different voltages from the ground voltage of the power supply of the battery exchange system (1) (the chassis ground voltage of the battery exchange system (1)).

[0091] The voltage / current measuring unit (121) can measure the insulation resistance of the line of the battery exchange device (11-1).

[0092] According to an embodiment, the first insulation resistance measuring unit (122) may include a first reference resistor (R1) connected between a power line (111) and a ground terminal, a first switch (S1) connected to the first reference resistor (R1), and a second switch (S2) connected between a ground line (112) and the ground terminal. The ground terminal may be the same as the ground voltage of the power of the battery exchange system (1) (the chassis ground voltage of the battery exchange system (1)).

[0093] The first switch (S1) and the second switch (S2) can switch the current flowing to the first insulation resistance measuring unit (122). For example, the first switch (S1) and the second switch (S2) can be at least one of a relay or a FET. The first switch (S1) and the second switch (S2) can be controlled by a controller (104, see FIG. 2).

[0094] The first reference resistance (R1) may be an insulation resistance that serves as a standard for judging the insulation state of the power line (111) of the battery exchange device (11-1). According to an embodiment, when the power line (111) is in a normal insulation state, the first insulation resistance value measured by the first insulation resistance measuring unit (122) may be the same as the first reference resistance (R1) value or a value within an equal range. The first reference resistance (R1) value is n*10 3 Ω (kΩ) to n*10 6 It can be between Ω (MΩ) (where n is a number between 1 and 1000), but is not limited thereto.

[0095]

[0096] According to the embodiment, when the insulation of the power line (111) is broken, the insulation resistance value of the power line (111) is a resistance (R) having a value smaller than the first reference resistance (R1) x , not shown) can be measured as if they were connected in parallel. In this case, the resistance (R x ) may be less than the value of the first reference resistor (R1). Resistance (R x ) has a value of nΩ to n*10 3 It may be between Ω (kΩ) (where n is a number between 1 and 1000), but is not limited thereto. According to an embodiment, when the power line (111) is in an insulation breakdown state, the measured first insulation resistance value may be less than half of the first reference resistance (R1) value.

[0097] The voltage / current measuring unit (121) can measure the second insulation resistance through the second insulation resistance measuring unit (123). According to an embodiment, the second insulation resistance measuring unit (123) can include a second reference resistor (R2) connected between the ground line (112) and the ground terminal, a third switch (S3) connected to the second reference resistor (R2), and a fourth switch (S4) connected between the power line (111) and the ground terminal. The ground terminal can be the same as the ground voltage of the power of the battery exchange system (1) (the chassis ground voltage of the battery exchange system (1)).

[0098] The third switch (S3) and the fourth switch (S4) can switch the current flowing to the second insulation resistance measuring unit (123). For example, the third switch (S3) and the fourth switch (S4) can be at least one of a relay or a FET. The third switch (S3) and the fourth switch (S4) can be controlled by a controller (104, see FIG. 2).

[0099] The second reference resistance (R2) may be an insulation resistance that serves as a standard for judging the insulation state of the ground line (112) of the battery exchange device (11-1). According to an embodiment, when the ground line (112) is in a normal insulation state, the second insulation resistance value measured by the second insulation resistance measuring unit (123) may be the same as the second reference resistance (R2) value or a value within an equal range. The second reference resistance (R2) value is n*10 3 Ω (kΩ) to n*10 6 It can be between Ω (MΩ) (where n is a number between 1 and 1000), but is not limited thereto.

[0100] According to the embodiment, when the insulation of the ground line (112) is broken, the insulation resistance value of the ground line (112) is a resistance (R) having a value smaller than the second reference resistance (R2) y , not shown) can be measured as if they were connected in parallel. In this case, the resistance (R y ) may be less than the value of the second reference resistor (R2). Resistance (R y ) has a value of nΩ to n*10 3 It may be between Ω (kΩ) (where n is a number between 1 and 1000), but is not limited thereto. In an embodiment, when the ground line (112) is in an insulation breakdown state, the measured second insulation resistance value may be less than half of the second reference resistance (R2) value.

[0101] In the embodiment of Fig. 4, four SPST (Single Pole Single Through) type switches (i.e., the first to fourth switches (S1, S2, S3, and S4)) are exemplified to switch the current flowing through the first insulation resistance measuring unit (122) and the second insulation resistance measuring unit (123), but the embodiment of the present invention is not limited to the embodiment of Fig. 4. According to other embodiments, the type, structure, number, etc. of the switches (or relays or FETs) can be changed according to ordinary creative ability. In this regard, an embodiment of an alternative switch is described with reference to Fig. 5 to be described later.

[0102] Continuing with reference to the embodiment of FIG. 4, the voltage / current measuring unit (121) can measure the insulation resistance of the first insulation resistance measuring unit (122) or the second insulation resistance measuring unit (123) by applying a current. According to the embodiment, the voltage / current measuring unit (121) can measure the insulation resistance through the first insulation resistance measuring unit (122) or the second insulation resistance measuring unit (123) under the control of the controller (104). For example, the controller (104) can control so that the current flows only to the first insulation resistance measuring unit (122) including the first reference resistor (R1), and so that the current does not flow to the second insulation resistance measuring unit (123) including the second reference resistor (R2).

[0103] The controller (104) can measure the first insulation resistance based on the current flowing through the first insulation resistance measuring unit (122). In this case, no current may flow through the second insulation resistance measuring unit (123).

[0104] The controller (104) can control the operations of the first switch (S1), the second switch (S2), the third switch (S3), and the fourth switch (S4) so ​​that current flows only to the first insulation resistance measurement unit (122). Specifically, the controller (104) can control the first to fourth switches (S1 to S4) so ​​that the first switch (S1) and the second switch (S2) are short-circuited and the third switch (S3) and the fourth switch (S4) are opened. In this case, a closed circuit (closed loop) including the voltage / current measurement unit (121), the power line (111), the first insulation resistance measurement unit (122), and the ground line (112) can be formed. Thereafter, the voltage / current measurement unit (121) can apply current to the insulation resistance measurement unit. In this case, current may flow in the closed circuit including the first insulation resistance measuring unit (122), and no current may flow in the second insulation resistance measuring unit (123). The voltage / current measuring unit (121) may measure the current passing through the first insulation resistance measuring unit (122) or the voltage across the first insulation resistance measuring unit (122). The voltage / current measuring unit (121) may measure the first insulation resistance, which is the insulation resistance of the power line (111), based on the current or voltage measured by the first insulation resistance measuring unit (122).

[0105] According to an embodiment, when the voltage / current measurement unit (121) includes an electrochemical impedance spectroscopy measurement system (EIS Measurement System), the voltage / current measurement unit (121) can measure the impedance of the first insulation resistance measurement unit (122).

[0106] The controller (104) can determine the insulation status of the power line (111) based on the first insulation resistance (or impedance) value measured by the first insulation resistance measuring unit (122). The controller (104) can compare the first insulation resistance value measured by the first insulation resistance measuring unit (122) with the first reference resistance (R1) value of the power line (111) to determine whether the power line (111) is in a normal insulation state or an insulation breakdown state.

[0107] If the measured first insulation resistance value is greater than or equal to the first reference resistance (R1) value, the controller (104) can determine that the power line (111) is in a normal insulation state. If the measured first insulation resistance value is less than the first reference resistance (R1) value, the controller (104) can determine that the power line (111) is in an insulation breakdown state.

[0108] As described above, when the insulation of the power line (111) is broken, a resistance (R) smaller than the first reference resistance (R1) is applied to the power line (111). x ) can be measured as if they are connected in parallel. Therefore, when measuring the insulation resistance of a power line (111) whose insulation has been broken, a first insulation resistance having a value smaller than the first reference resistance (R1) can be measured.

[0109] If the power line (111) is in an insulation breakdown state, maintenance of the battery exchange device (11-1) may be required. Even if the power line (111) is in a normal insulation state, if the ground line (112) is in an insulation breakdown state, maintenance of the battery exchange device (11-1) may be required. Therefore, the controller (104) can measure both the insulation resistance of the power line (111) and the insulation resistance of the ground line (112) to ensure safe use of the battery exchange device (11-1).

[0110] In a similar manner to the insulation resistance measurement of the power line (111) described above, the insulation resistance of the ground line (112), i.e., the second insulation resistance, can be measured.

[0111] According to an embodiment, the controller (104) can control so that current flows only to the second insulation resistance measuring unit (123) including the second reference resistor (R2) and so that current does not flow to the first insulation resistance measuring unit (122) including the first reference resistor (R1). The controller (104) can control so that current flows only to the second insulation resistance measuring unit (123) by controlling the operations of the first switch (S1), the second switch (S2), the third switch (S3), and the fourth switch (S4).

[0112] Specifically, the controller (104) can control the first to fourth switches (S1 to S4) so ​​that the third switch (S3) and the fourth switch (S4) are short-circuited and the first switch (S1) and the second switch (S2) are opened. In this case, a closed circuit (closed loop) including the voltage / current measuring unit (121), the power line (111), the second insulation resistance measuring unit (123), and the ground line (112) can be formed. Thereafter, the voltage / current measuring unit (121) can apply current to the insulation resistance measuring unit. In this case, current may flow in the closed circuit including the second insulation resistance measuring unit (123), and no current may flow in the first insulation resistance measuring unit (122). The voltage / current measuring unit (121) can measure the current passing through the second insulation resistance measuring unit (123) or the voltage across the second insulation resistance measuring unit (123). The voltage / current measuring unit (121) can measure the second insulation resistance, which is the insulation resistance of the ground line (112), based on the current or voltage measured by the second insulation resistance measuring unit (123).

[0113] According to an embodiment, when the voltage / current measurement unit (121) includes an electrochemical impedance spectroscopy measurement system (EIS Measurement System), the voltage / current measurement unit (121) can measure the impedance of the second insulation resistance measurement unit (123).

[0114] The controller (104) can determine the insulation status of the ground line (112) based on the second insulation resistance (or impedance) value measured by the second insulation resistance measuring unit (123). The controller (104) can compare the second insulation resistance value measured by the second insulation resistance measuring unit (123) with the second reference resistance (R2) value of the ground line (112) to determine whether the ground line (112) is in a normal insulation state or an insulation breakdown state.

[0115] If the measured second insulation resistance value is greater than or equal to the second reference resistance (R2) value, the controller (104) can determine that the ground line (112) is in a normal insulation state. If the measured second insulation resistance value is less than the second reference resistance (R2) value, the controller (104) can determine that the ground line (112) is in an insulation breakdown state.

[0116] As described above, when the insulation of the ground line (112) is broken, a resistance (R) smaller than the second reference resistance (R2) is applied to the ground line (112). y ) can be measured as if they are connected in parallel. Therefore, when measuring the insulation resistance of the ground line (112) whose insulation is broken, a second insulation resistance having a value smaller than the second reference resistance (R2) can be measured.

[0117] If the ground line (112) is in an insulation breakdown state, maintenance of the battery exchange device (11-1) may be required. Even if the ground line (112) is in a normal insulation state, if the power line (111) is in an insulation breakdown state, maintenance of the battery exchange device (11-1) may be required.

[0118] As described above, if the insulation of either the power line (111) or the ground line (112) is broken, problems may arise in charging and discharging the battery due to high current or high voltage. Furthermore, damage may occur to the battery exchange system (1). Therefore, measuring and managing the insulation resistance of the battery exchange system (1) may be important for maintenance of the battery exchange system (1) or for the safety of users of the battery exchange system (1).

[0119] In addition, according to an embodiment of the present invention, the controller (104) can measure the insulation resistance of the power line (111) and the insulation resistance of the ground line (112) by controlling the switching of the switch (S0) and the first to fourth switches (S1, S2, S3, and S4), respectively. Therefore, even while the battery exchange system (1) is in operation, the insulation resistance of the battery exchange device (11-1) can be easily measured and maintained without external manipulation.

[0120] FIG. 5 is a circuit diagram showing a battery exchange device according to another embodiment disclosed in this document.

[0121] Referring to Fig. 5, a fifth switch (S5) and a sixth switch (S6) are illustrated as alternative embodiments of the first to fourth switches (S1, S2, S3, and S4). The fifth switch (S5) and the sixth switch (S6) can switch the current flowing to the first insulation resistance measuring unit (122) and the second insulation resistance measuring unit (123). According to an embodiment, the fifth switch (S5) and the sixth switch (S6) can be SPDT (Single Pole Double Through) type switches.

[0122] Figure 6 is a flowchart illustrating the operation of a battery exchange system according to one embodiment disclosed in this document. Figure 6 can be interpreted with reference to Figures 1 to 5.

[0123] Referring to FIG. 6, in operation S101, the battery exchange system (1) can receive a battery exchange request from a user. The battery exchange system (1) can receive a battery exchange request input via a control panel (13). In addition, the battery exchange system (1) can receive a battery exchange request transmitted via a server via an integrated controller (14). The integrated controller (14) can receive a battery exchange request from a user via a wired or wireless connection.

[0124] Next, in operation (S102), the battery exchange system (1) can check whether there is a battery exchange device that does not accept a battery among the plurality of battery exchange devices (11-1, 11-2, ..., 11-n). The integrated controller (14) can check whether a battery is connected to the connection part (101). The integrated controller (14) can determine a battery exchange device (e.g., 11-1) that does not accept or occupy a battery as a battery exchange device that does not accept a battery.

[0125] Next, in operation (S103), the integrated controller (14) can transmit a request for measuring the insulation resistance of the battery exchange device (11-1) in which the battery is not received to the controller (104) of the battery exchange device (11-1). The controller (104) can control the measuring unit (103) to measure the insulation resistance of the battery exchange device (11-1). The measuring unit (103) can measure at least one of the first insulation resistance of the power line (111) and the second insulation resistance of the ground line (112). The method for measuring the insulation resistance is the same as described above and is therefore not described again herein.

[0126] Next, in operation (S104), the controller (104) can determine the insulation status of the battery exchange device (11-1) based on the first insulation resistance of the measured power line (111) and the second insulation resistance of the measured ground line (112). The controller (104) can compare the insulation resistance value measured in the battery exchange device (11-1) in which no battery is received with a reference resistance value. Based on the comparison result, the controller (104) can determine whether the battery exchange device (11-1) is in a normal insulation status or an insulation breakdown status. The method for determining the insulation status is the same as described above and is therefore not described again herein.

[0127] The controller (104) can transmit the insulation status of the battery exchange device (11-1) to the integrated controller (14). The controller (104) can transmit to the integrated controller (14) whether the battery exchange device (11-1) is in a normal insulation state or an insulation breakdown state.

[0128] Next, in operation (S105), the integrated controller (14) can determine whether the battery exchange device (11-1) is available for use based on the insulation status of the battery exchange device (11-1).

[0129] According to an embodiment, if the battery exchange device (11-1) is determined to be in a normal insulation state, the integrated controller (14) may determine that the battery exchange device (11-1) is available for use. Accordingly, the integrated controller (14) may provide the battery exchange device (11-1) for use by the user.

[0130] On the other hand, if the battery exchange device (11-1) is determined to be in an insulation breakdown state, the integrated controller (14) may determine that the battery exchange device (11-1) is unusable. Accordingly, the integrated controller (14) may not provide the battery exchange device (11-1) to the user.

[0131] Figure 7 is a flowchart illustrating the operation of a battery exchange system according to another embodiment disclosed in this document. Figure 7 can be interpreted with reference to Figures 1 to 5.

[0132] Referring to FIG. 7, in operation (S201), the battery exchange system (1) can periodically measure the insulation resistance of a plurality of battery exchange devices (11-1, 11-2, ..., 11-n). The battery exchange system (1) can stop the use of a battery exchange device that is in use among the plurality of battery exchange devices (11-1, 11-2, ..., 11-n) for the insulation resistance measurement.

[0133] According to an embodiment, among the plurality of battery exchange devices (11-1, 11-2, ..., 11-n) in the battery exchange system (1), some of the battery exchange devices (e.g., 11-1 and 11-2) may not be in use. In addition, some of the remaining battery exchange devices (e.g., 11-3 to 11-n) may be in use. The integrated controller (14) may stop the use of the battery exchange devices (11-3 to 11-n) in use at predetermined first time intervals. According to an embodiment, the controller (104) of each of the battery exchange devices (11-3 to 11-n) in use may stop charging of each of the battery exchange devices (11-3 to 11-n) in use. The controller (104) may cut off the electrical connection between the power source (12) and the battery being charged. For example, the controller (104) can control the power switch (102) of each of the battery exchange devices (11-3 to 11-n) to be opened.

[0134] Thereafter, the integrated controller (14) can transmit an insulation resistance measurement request to the controller (104) of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n).

[0135] Next, in operation (S202), the controller (104) can measure the insulation resistance of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n). The controller (104) can control the measurement unit (103) to measure the insulation resistance of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n). The measurement unit (103) can measure at least one of the first insulation resistance of the power line (111) and the second insulation resistance of the ground line (112). The method of measuring the insulation resistance is the same as described above and is therefore not described again herein.

[0136] Next, in operation (S203), the controller (104) of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n) can determine the insulation status of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n) based on the first insulation resistance of the measured power line (111) and the second insulation resistance of the measured ground line (112). The method of determining the insulation status is the same as described above and is therefore not described again herein.

[0137] The controller (104) can transmit the insulation status of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n) to the integrated controller (14). The controller (104) can transmit to the integrated controller (14) whether the battery exchange device (11-1) is in a normal insulation state or an insulation breakdown state.

[0138] Next, in operation (S204), the integrated controller (14) can determine whether maintenance of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n) is required based on the insulation status of each of the plurality of battery exchange devices (11-1, 11-2, ..., 11-n).

[0139] According to an embodiment, if the battery exchange device (11-1) is determined to be in a normal insulation state, the integrated controller (14) may determine that maintenance of the battery exchange device (11-1) is unnecessary. If the battery exchange device determined to be in a normal insulation state is the battery exchange device (11-3) that was in use, the integrated controller (14) may cause the controller (104) of the battery exchange device (11-3) to resume use of the battery exchange device (11-3). For example, the controller (104) may resume charging of the battery accommodated in the battery exchange device (11-3).

[0140] In another embodiment, if the battery exchange device (11-1) is determined to be in an insulation breakdown state, the controller (104) may determine that the battery exchange device (11-1) requires maintenance. If the battery exchange device determined to be in an insulation breakdown state is the battery exchange device (11-3) that was in use, the integrated controller (14) may not resume use of the battery exchange device (11-3). In addition, the integrated controller (14) may transmit a maintenance request for the battery exchange device (11-3) to the server.

[0141] Through the operation of this battery exchange system (1), the safety of each of the multiple battery exchange devices (11-1, 11-2, ..., 11-n) can be periodically evaluated. In addition, the battery exchange system (1) can be efficiently maintained by itself.

[0142] FIG. 8 is a block diagram showing the hardware configuration of a computing system for implementing a battery exchange system according to one embodiment disclosed in this document.
