Thereafter, the charge controller calculates position identification information for the charge slot in which the battery pack is mounted (S808), and transmits the calculated battery identification information and the position identification information to the battery pack through the battery charger (S810). Thereafter, the battery pack recognizes the received battery identification information and the location identification information (S812), and performs data transmission / reception with the battery charger (S814).

9 is a flowchart illustrating a method of identifying a location of an electric vehicle battery pack according to an embodiment of the present invention.

The battery pack receives an electrical signal for positioning the battery pack of the electric vehicle through at least one positioning pin from the charging device or the electric vehicle of the battery pack (S900). The positioning pins may be configured in at least one or more of the battery packs. However, the number of positioning pins can be increased or decreased according to the degree of fragmentation of the identification information required to identify the position of the battery pack. Here, the electrical signal received from the charging device or the electric vehicle may be, for example, either 0 [v] or 5 [v].

After step S900, the battery pack calculates the position identification information of the battery pack corresponding to the received electrical signal (S902). The location identification information is information that allows the user to check where the battery pack is located in the electric vehicle or the charging device. For example, when the electric signal received through the positioning pin is 0 [v], the electric signal of 0 [v] can be determined as the binary value "0 & , The electric signal of 5 [v] can be determined as the binary value "1 ". The battery pack can calculate the position identification information of the battery pack by a combination of the respective electrical signals corresponding to the plurality of positioning pins.

After step S902, the battery pack determines the position of the battery pack using the calculated position identification information (S904). For example, if any one of "0x200 to 2FF", "0x300 to 3FF", "0x400 to 4FF", "0x500 to 5FF", and "0x600 to 6FF" is calculated as the position identification information, The position information "Charger 1 to 5" corresponding to the position identification information can be calculated using the table information in Table 1. [ Based on the position information thus calculated, the battery pack can determine that its position is located in one of the chargers of the charging apparatus, that is, "Charger 1 to 5 ". If the position identification information "0x700 to 7FF" is calculated, the battery pack can calculate the position information corresponding to the position identification information calculated using the table information in Table 1, that is, the main battery slot "BUS 1" . Based on the calculated position information, the battery pack can determine that its position is located in the main battery slot of the electric vehicle. Further, if the position identification information "0x800 ~ 8FF" is calculated, the battery pack can calculate the position information corresponding to the position identification information calculated using the table information in Table 1, that is, the sub battery slot "BUS 2 ". Based on the calculated position information, the battery pack can determine that its position is located in the sub-battery slot of the electric vehicle.

10 is a flow chart of another embodiment for explaining a method of identifying a location of an electric vehicle battery pack according to the present invention.

The charging device or electric vehicle generates an electrical signal for positioning the battery pack (S1000). For example, the charging device or the electric vehicle generates one of 0 [v] or 5 [v] as an electrical signal. However, as an electrical signal, 0 [v] or 5 [v] is an example, and electrical signals of various sizes can be generated as needed.

The charging device or electric vehicle transmits the generated electric signal to the battery pack (S1002). When the battery pack is mounted in the charging slot, the charging device is connected to the positioning pin of the battery pack. Thereby, the charging device transfers the generated electric signal to the battery pack through the positioning pin. On the other hand, when the battery pack is mounted in the vehicle slot of the electric vehicle, the electric vehicle is connected to the positioning pin of the battery pack. Thus, the electric vehicle transmits the generated electric signal to the battery pack through the positioning pin.

11 is a flowchart illustrating a method of identifying a location of an electric vehicle battery pack according to another embodiment of the present invention.

The battery pack receives position identification information and / or battery identification information for positioning the electric vehicle battery pack from the charging device or the electric vehicle (S1100). When the battery pack is mounted in the charging slot of the charging apparatus, the charging apparatus can calculate the position identification information of the battery pack and transmit the calculated position identification information to the battery pack. Accordingly, the battery pack can receive the location identification information transmitted from the charging device. Further, the battery pack can receive battery identification information for the battery pack from the charging device in addition to the location identification information. The battery identification information is unique identification information assigned to the battery pack to distinguish the plurality of battery packs from one another.

On the other hand, when the battery pack is mounted in the vehicle slot of the electric vehicle, the electric vehicle can calculate the position identification information of the battery pack and transmit the calculated position identification information to the battery pack. Accordingly, the battery pack can receive position identification information transmitted from the electric vehicle.

The battery pack can receive position identification information and / or battery identification information through wireless communication such as WiFi, bluetooth, near field communication (NFC), and radio frequency identification (RFID). To this end, the battery pack supports wireless communications such as WiFi, Bluetooth, NFC and RFID.

After step S1100, the battery pack determines the position of the battery pack using the received location identification information and / or the battery identification information (S1102). For example, the battery pack can determine the position of the battery pack corresponding to the received location identification information, as described in Table 1. [ The location identification information is information that allows the user to check where the battery pack is located in the electric vehicle or the charging device. Thus, the battery pack can determine the position of either the electric vehicle or the charging device as the position of the battery pack. In particular, if the battery identification information is received together with the location identification information, the location corresponding to the received battery identification information and the location identification information can be determined.

12 is a flowchart illustrating a method of identifying a location of an electric vehicle battery pack according to another embodiment of the present invention.

The charging device or electric vehicle detects whether or not the battery pack is mounted (S1200). The charging device uses the charge detection sensor configured on the charge slot to detect whether the battery pack is mounted in the charge slot. On the other hand, the electric vehicle senses whether or not the battery pack is mounted in the vehicle slot by using the vehicle detection sensor configured on the vehicle slot.

After step S1200, the charging device or the electric vehicle calculates the position identification information corresponding to the battery pack according to the detection result (S1202). If it is determined that the battery pack is mounted in the charging slot, the charging device calculates position identification information corresponding to the charging slot in which the battery pack is mounted. On the other hand, if it is determined that the battery pack is mounted in the vehicle slot, the electric vehicle calculates the position identification information corresponding to the vehicle slot on which the battery pack is mounted.

After step S1202, the charging device or the electric vehicle transmits the calculated location identification information to the battery pack (S904). The charging device or the electric vehicle may transmit the location identification information to the battery pack through wireless communication of at least one of WiFi, bluetooth, near field communication (NFC), and radio frequency identification (RFID).

FIG. 13 is a flowchart illustrating a method of identifying a location of an electric vehicle battery pack according to another embodiment of the present invention.

The charging device extracts battery identification information for the battery pack (S1300). The battery pack stores unique battery identification information in an RFID chip, an NFC chip, or a separate memory space. The charging device can extract battery identification information stored in an RFID chip, an NFC chip, or a separate memory of the battery pack through data exchange.

After step S1300, the charging device determines whether to replace the battery pack for charging (S1302). The charging device can determine the replacement of the battery pack by detecting the amount of power remaining in the battery pack.

After the step S1302, if the battery pack is determined to be replaced, the charging device calculates the position identification information corresponding to the battery pack (S1304). The charging device can calculate the position identification information based on the transfer information of the transfer robot that transfers the battery pack to the charging slot. The charging device can confirm the position identification information of the charging slot of the transfer robot that carried the battery pack. Therefore, the charging device calculates the position identification information of the charging slot on which the battery pack is mounted based on the transfer information of the transfer robot. Here, the location identification information indicates location information of the charging slot of the battery pack.

After step S1304, the charging device transmits the calculated location identification information and / or battery identification information to the battery pack (S1306). The charging device may transmit location identification information and / or battery identification information to the battery pack through at least one of wireless communication such as WiFi, bluetooth, near field communication (NFC), and radio frequency identification (RFID) .
