Description

Battery power control system, electronic control device, battery module

The present invention relates to a battery module that is detachable from a load device, an electronic control device that is mounted on the load device, and a battery power control system that includes these components.

For example, a battery module having a battery is connected to a load device such as an electric motorcycle. The battery module is detachable from the load device and is charged by a charger. A load such as a traveling motor provided in the load device consumes electric power of the battery of the battery module. An electronic control device that controls battery power supply to the load is mounted on the load device.

Patent Document 1 and Patent Document 2 disclose techniques for preventing subsequent unauthorized use of a battery module when the battery module is removed from the load device and stolen.

In Patent Document 1, individual identification codes are attached to secondary batteries and secondary battery using devices. In addition, the charging device includes a charging circuit, an individual identification code recognition circuit, and a charging control circuit. The individual identification code recognition circuit detects the individual identification code from the secondary battery or the secondary battery using device. The charge control circuit compares the individual identification code detected by the individual identification code recognition circuit with the individual identification code of the rechargeable secondary battery stored in advance. When the two individual identification codes match, the charging circuit is switched to the charging state, and when both the individual identification codes do not match, the charging circuit is switched to the charging stop state.

In Patent Document 2, vehicle specific information and battery specific information are stored in association with each other in an information database of a management center. And when charging a battery in a vehicle, vehicle specific information and battery specific information are transmitted to a management center from a charging device or a vehicle. When the received vehicle identification information and battery identification information do not match the relationship stored in the information database, the management center transmits a charge inhibition signal to inhibit battery charging.

If the identification information is attached to the battery module and the load device as in Patent Document 1 and Patent Document 2, for example, power can be supplied from the battery to the load only when the identification information of the both matches. This prevents unauthorized use of stolen battery modules and load devices.

Next, operations of the electronic control device 1a and the battery module 2 when registering the identification ID according to the first embodiment will be described with reference to FIGS.

When the battery module 2 is first attached to the load device 1, a legitimate user performs a predetermined operation determined by the user at the password input unit 13 (for example, after operating the brake three times and then operating the clutch once) ) To enter the password. In addition, by performing a predetermined operation (for example, pressing a button) in the registration receiving unit 14, the registration of the identification ID to the battery module 2 is instructed.

Thereby, the control unit 11 of the electronic control device 1a determines that there is an input of a password (step S1: YES in FIG. 2) and that an instruction to register an identification ID has been received (step S2: YES). And the identification ID of the load apparatus 1 memorize | stored in the memory | storage part 16 is read by ID reading part 11b (step S3). Further, the input password and the read identification ID are transmitted to the battery module 2 by the communication unit 17 (step S4).

When the control unit 21 of the battery module 2 receives the password and the identification ID transmitted from the electronic control device 1a by the communication unit 27 (step S11 in FIG. 3: YES), is the identification ID stored in the storage unit 26? Confirm whether or not.

If no identification ID is stored in the storage unit 26, the control unit 21 determines that the identification ID is unregistered (step S12: YES). Then, the received identification ID is written into the storage unit 26 by the writing unit 21d (step S13). As a result, the same identification ID as the identification ID stored in the electronic control device 1 a of the load device 1 is registered in the storage unit 26 of the battery module 2.

Further, the control unit 21 writes the received password in the storage unit 23 by the writing unit 21d (step S14). As a result, the password input to the password input unit 13 of the electronic control device 1 a of the load device 1 is registered in the storage unit 23 of the battery module 2.

On the other hand, if the identification ID is already stored in the storage unit 26 of the battery module 2, the control unit 21 determines that the identification ID is not unregistered (step S12: NO). Then, the received password is compared with the password registered in the storage unit 23 (step S15).

As a result of the comparison, if the passwords match (step S16: YES), the writing unit 21d additionally writes the received identification ID in the storage unit 26 (step S17). As a result, the same identification ID as the identification ID stored in the electronic control device 1 a of the load device 1 is additionally registered in the storage unit 26 of the battery module 2. That is, a plurality of identification IDs are stored in the storage unit 26.

On the other hand, if the received password does not match the registered password (step S16: NO), the identification ID and password are not registered.

Next, operations of the electronic control device 1a and the battery module 2 when the load 1b according to the first embodiment is started will be described with reference to FIGS.

The battery module 2 is mounted on the load device 1, the battery module 2 and the electronic control device 1a are electrically connected, and the battery 22 and the load 1b are electrically connected. To turn on. Then, the control unit 11 of the electronic control device 1a determines that the start receiving unit 12 has received a start instruction for the load 1b (step S21 in FIG. 4: YES). And identification ID of the load apparatus 1 memorize | stored in the memory | storage part 16 is read by ID reading part 11b (step S22).

Further, the identification ID stored in the storage unit 26 of the battery module 2 is read out by the ID reading unit 11a (step S23). Specifically, in response to a read request from the ID reading unit 11a, the control unit 21 of the battery module 2 reads the identification ID from the storage unit 26 and transmits the identification ID to the electronic control device 1a by the communication unit 27.

At this time, when a plurality of identification IDs are stored in the storage unit 26, for example, all the identification IDs are read from the storage unit 26 and transmitted to the electronic control device 1a. When the identification ID is not stored in the storage unit 26, for example, the control unit 21 notifies the control unit 11 that the identification ID is not stored in the storage unit 26.

If the identification ID is not stored in the storage unit 26 of the battery module 2, the control unit 11 of the electronic control device 1a determines that the identification ID is not registered (step S24: YES). And it is displayed by the display mode 15b of the display part 15 that there is no security in the battery module 2 (step S25). At this time, as shown in FIG. 6B, the circle of the display mode 15b and the characters “no security” are turned on in yellow, and the

other display modes

15a and 15c are turned off. FIG. 6 shows an example in which the display modes 15a to 15c of the display unit 15 are configured like traffic signals.

On the other hand, if the identification ID is stored in the storage unit 26 of the battery module 2, the control unit 11 determines that the identification ID is not registered (step S24 in FIG. 4: NO). Then, the identification ID of the load device 1 read by the ID reading unit 11b and the identification ID of the battery module 2 read by the ID reading unit 11a are compared by the comparison unit 11c (step S26).

As a result of the comparison, when the identification ID of the load device 1 matches one of the identification IDs of the battery module 2 (step S27: YES), the control unit 11 provides security to the battery module 2 by the display mode 15a of the display unit 15. It is displayed (step S28). At this time, as shown in FIG. 6A, the circle of the display mode 15a and the characters “with security” are turned on in blue, and the

other display modes

15b and 15c are turned off.

After the display in step S25 or S28 of FIG. 4, the power control unit 11d of the control unit 11 transmits a power supply permission signal to the battery module 2 by the communication unit 17 (step S29).

When the control unit 21 of the battery module 2 receives this power supply permission signal by the communication unit 27 (step S30 in FIG. 5: YES), the control unit 21 switches the power switching unit 28 to the ON state, and the power of the battery 22 is changed. Supply to the load 1b (step S31). Thereby, the control part 11 of the electronic controller 1a starts the load 1b with the electric power of the battery 22 (step S32 of FIG. 4).

On the other hand, as a result of the comparison in step S26, if the identification ID of the load device 1 does not match any identification ID of the battery module 2 (step S27: NO), the control unit 11 causes the display mode 15c of the display unit 15 to Then, it is displayed that the battery 22 of the battery module 2 cannot be used (step S33). At this time, as shown in FIG. 6C, the circle of the display mode 15c and the characters “unavailable battery” are turned on in red, and the

other display modes

15a and 15b are turned off.

And the electric power control part 11d of the control part 11 transmits an electric power supply prohibition signal to the battery module 2 by the communication part 17 (step S34). When the control unit 21 of the battery module 2 receives this power supply prohibition signal by the communication unit 27 (step S35 in FIG. 5: YES), the control unit 21 switches the power switching unit 28 to the off state and supplies the power of the battery 22 to the load 1b. On the other hand, it is blocked (step S36). Thereby, the control part 11 keeps the load 1b stopped (step S37 of FIG. 4).

According to the first embodiment, when the battery module 2 is attached to the load device 1 and the load 1b is started, the identification stored in each of the electronic control device 1a and the battery module 2 mounted on the load device 1 IDs are compared. As a result of the comparison, when the identification IDs match, the power of the battery 22 of the battery module 2 is supplied to the load 1b. When the identification IDs do not match, the power of the battery 22 corresponds to the load 1b. Blocked. For this reason, for example, unauthorized use of the battery module 2 or the load device 1 in which identification IDs that are stolen and do not match can be prevented.

Further, even when the identification ID is not stored in the storage unit 26 of the battery module 2, the power of the battery 22 is supplied to the load 1b after displaying no security. For this reason, for example, the battery module 2 that has been purchased by the user and whose identification ID is not stored can be used in the load device 1 in place of the existing battery module 2. Therefore, the usability of the battery module 2 and the load device 1 can be improved.

Further, the display unit 15 displays the case where the identification information stored in the battery module 2 and the load device 1 respectively match or does not match, and when the identification ID is not stored in the battery module 2. Embodiments 15a-15c vary. Therefore, the user can recognize the correctness of the combination of the battery module 2 and the load device 1 by the display modes 15a to 15c of the display unit 15. In addition, the display modes 15a to 15c can recognize the safety of the battery module 2 and the approval / disapproval of the battery 22. Therefore, the usability of the battery module 2 and the load device 1 can be further improved.

Further, when a registration instruction is received by the registration receiving unit 14 of the electronic control device 1 a and a password is input by the password input unit 13, the identification ID stored in the storage unit 16 is used as the storage unit 26 of the battery module 2. Is writing. For this reason, identification ID can be safely provided with respect to the battery module 2 from the electronic control apparatus 1a.

Further, when the identification ID is already stored in the storage unit 26 of the battery module 2 and the input password matches the password stored in the storage unit 23, the identification ID is stored in the storage unit 16 of the electronic control device 1a. Identification ID information is additionally written in the storage unit 26. For this reason, a plurality of identification IDs can be safely given to the battery module 2 from the electronic control device 1a.

Furthermore, when a plurality of identification IDs are stored in the storage unit 26 of the battery module 2, a plurality of battery modules 2 and load devices 1 can be owned and used in any combination. For example, each time the battery module 2 is owned and a load device 1 consumes the power of the battery 22 of the battery module 2, the battery module 2 can be replaced. One battery module 2 can be reused by a plurality of load devices 1.

Next, the configuration of the battery power control system 102 of the second embodiment will be described with reference to FIG.

In the battery power control system 102, not the control unit 11 'of the electronic control device 1a but the control unit 21' of the battery module 2 includes

ID reading units

21a and 21b, a comparison unit 21c, and a display control unit 21f.

The ID reading unit 21 a reads the identification ID stored in the storage unit 26. The ID reading unit 21b reads the identification ID stored in the storage unit 16 of the electronic control device 1a via the

communication units

27 and 17 and the control unit 11 '. The ID reading unit 21a is an example of the “first reading unit” in the present invention, and the ID reading unit 21b is an example of the “second reading unit” in the present invention.

The comparison unit 21c compares the identification IDs read by the

ID reading units

21a and 21b. The display control unit 21f transmits a display signal to the electronic control device 1a to control the display modes 15a to 15c of the display unit 15. The display control unit 21f is an example of the “notification control unit” in the present invention.

Next, operations of the electronic control device 1a and the battery module 2 at the time of starting the load 1b according to the second embodiment will be described with reference to FIGS. The operation at the time of registering the identification ID is basically the same as in the case of the first embodiment (FIGS. 2 and 3), and thus the description thereof is omitted.

The battery module 2 is mounted on the load device 1, the battery module 2 and the electronic control device 1a are electrically connected, and the battery 22 and the load 1b are electrically connected. To turn on. Thus, the control unit 11 ′ notifies the control unit 21 ′ of the battery module 2 via the

communication units
