Description
1 2341258 MONITORING SYSTEM FOR A PLURALITY OF BATTERY PACKS OF ELECTRONIC
EQUIPMENT The present invention relates to a monitoring system for a plurality of battery packs of electronic equipment, and more particularly to a monitoring system in which a battery ID is set only to one battery pack.
The use of a battery apparatus in portable electronic equipment, such as laptop computers and cellular phones, enables the electronic equipment to be carried and used during travel. It is convenient if a user is able to obtain battery status information. Battery status information may include, for example, remaining battery capacity and the time when charging will complete. - In order to display this sort of status information on a screen of the electronic equipment, it is necessary to have a system for monitoring the battery within the electronic equipment.
One system for monitoring and controlling batteries used to operate electronic equipment is the smart battery system. The smart battery system connects through a bus, which can bidirectionally transmit control signals, a system host controller for controlling the electronic equipment, a battery charger, and a battery pack with built-in microcomputer, and can monitor and control the battery condition, the charging condition for the charger, and so forth. Information is transferred by issuing a monitor command from the system host controller via the bus!-o the battery pack and sending a 2 response signal from the microcomputer built into the battery pack to the system controller via the bus.
Information sent to the system host controller from the battery pack includes status information, such as temperature, voltage, current, remaining battery capacity, required charging time, and number of charge-discharge cycles, and attribute information, such as rated capacity and voltage of the battery itself.
The battery pack in the smart battery system of the prior art has a battery ID. The system host controller, charger, and other devices identify the battery pack through this battery ID. Therefore, the system host controller is capable of monitoring only the battery packs that have battery IDs.
In this smart battery system, the system host controller can identify only one battery ID so that only one battery pack can communicate with the host computer. However, in order to extend the operating time of electronic equipment, it is necessary to provide a plurality of battery packs. Thus, a monitoring system capable of communicating information with a plurality of battery packs using one battery ID is desirable.
Furthermore, providing a switching device in the smart battery system makes it possible to monitor a plurality of battery packs with, in essence, one battery ID. However, in this case, a large switching device is additionally required within the electronic equipment. Taking into consideration the trend of miniaturizing electronic equipment, a system that obviates such a switching circuit is desirable in terms of 3 reducing the size of the circuitry within the electronic_ equipment.
The present invention has an object to provide, in the battery pack monitoring system having only one or a predetermined number of battery IDs, a system capable of monitoring a plurality or a predetermined number or more of battery packs without using switching circuits.
The monitoring system for a plurality of battery packs pertaining to the first invention comprises a host control circuit for controlling an electronic equipment, one or more master battery packs that the host control circuit can identify, one or more slave battery packs that the host control circuit cannot identify, and a bus enabling bi-directional transmission and reception of signals among the host control circuit, the master battery pack and the slave battery pack. The master battery pack comprises receiving means for receiving a battery status transmit command from the host control circuit, processing means for requesting the slave battery pack to transmitstatus information in response to the battery status transmit command, and for processing the status information sent from the slave battery pack as requested, and transmitting means for transmitting the processed result to the host control circuit.
The bus may comprise one or wore master connectors assigning an ID which the host control circuit can identify to the connected battery pack (or packs), and one or more slave connectors not assigning an ID which the host control circuit can identify to the connected battery pack (or packs). The master battery pack is the battery pack connected to the master connector and the slave battery pack is the battery pack connected to the slave connector.
The battery status transmit command may be a command for inquiry of remaining battery capacity, and the processing means of the master battery pack requests the slave battery pack to transmit remaining battery capacity information, and performs summation of remaining battery capacity information sent from the slave battery pack as requested and remaining battery capacity information of the master battery pack.
Another aspect of the invention provides the monitoring system for a plurality of battery packs, wherein the electronic equipment compnses.
a master connector allowing the battery pack to be mounted to the electronic equipment main unit and assigning an ID, which the host control circuit can identify, to the battery pack that is connected to the connector., and a slave connector not assioning the ID, which the host control circuit can 1:1 W identify, to the battery pack that is connected to the connector.
the battery pack that is connected to the master connector and assigned with said ID becomes the master battery pack, and the battery pack that is connected to the slave connector and not assigned with said ID becomes the slave battery pack.
Since the present invention has the structure as described above, in the system for monitoring with the host computer only the battery pack assigned with the batten, ED, a plurality of battery packs not assigned with the battery ID can also be monitored without using switching devices.
Furthermore, by providing an identification terminal in the battery bays for identifying the roles of the battery packs, it becomes possible to use battery packs that have the same performance.
The invention will be further described by way of non-limitative example, in which:- Fig. 1 is a block diagram of a monitoring system for a plurality of battery packs showing embodiment 1 of this invention.
Fig. 2 is a flowchart showing an operational procedure of 5 the monitoring system for a plurality of battery packs in Fig. 1.
Fig. 3 is a block diagram of the monitoring system for a plurality of battery packs showing embodiment 2 of this invention.
Embodiment 1 The monitoring system concerned with in the present invention is illustrated in Fig. 1. In this embodiment, a battery apparatus for connecting a plurality of external battery packs to a PC main unit 1 is given as an example. Naturally, the present invention is also applicable between internal and external batteries.
The PC main unit 1 has a host control circuit 3 with a built-in microcomputer 2, a plurality of battery bays 4 for connecting external battery packs, and a bus 5 for bidirectionally transmitting information. The battery bays 4 have connectors for connecting the battery packs to the bus 5. The external battery packs include a master battery pack 6 and slave battery packs 7, and each comprise a battery (not shown) formed from a plurality of cells and a microcomputer 8 for internal battery control. The master battery pack 6 has a battery ID by which the host control circuit 3 identifies the battery pack. In this case, XX is the identifying battery ID.
6 on the other hand, the slave battery packs 7 do not have battery IDs for the purpose of identification and are thus not identified by the host control circuit 3. The host control circuit 3 and each battery bay 4 are mutually connected by the bus 5 so that bi-directional transfer of information is possible between battery bays 4 as well as between the host control circuit 3 and the battery bays 4. The battery packs 6, 7 and the battery bays 4 are connected by plugging the pins that have been disposed on the battery packs 6, 7 into the battery bays 4. Broken lines 9 indicate a state where battery packs 6, 7 are connected to the battery bays 4 and communication is possible via the bus.
The present invention is applicable provided the number of slave battery packs 7 is one or more. There is no particular limit on the number of battery packs.
The microcomputer 8 of the master battery pack 6 comprises receiving means 10 for receiving a battery status transmit command from the host control circuit 3, processing means 11 for requesting the slave battery pack 7 to transmit status information in response to the transmit command and for performing such processes as summation and maximum value detection for internal battery status information sent from the slave battery packs 7 and internal status information of the master battery pack 6, and transmitting means 12 for transmitting the processed result to the host control circuit 3.
On the other hand, the slave battery packs 7, the existence of which is recognized by the master battery pack 6, 7 have IDs for performing transfers of information. As shown in Fig. 1, the slave battery pack 7 connected to the second battery bay 4 has an ID of YY and the slave battery pack 7 connected to the n-th battery bay 4 has an ID of ZZ. The microcomputer of the slave battery pack 7 does not have the function of receiving means 10 in the master battery pack 6 and only checks the internal battery condition according to a monitor command from the master battery pack 6 and transmits a status information signal to the master battery pack 6. The microcomputer of the slave battery pack 7 may include receiving means 10, which is set not to function whenever the battery pack identifies itself as the slave battery pack.
The operational procedure of the monitoring system for the battery packs is shown using Fig. 2. The monitor command herein gives the remaining battery capacity as an example.
First, an inquiry command of remaining battery capacity is sent (S101) from the host control circuit 3 to the master battery pack 6 having battery ID:M Only the master battery pack 6 having the battery ID of XX receives this inquiry command of remaining capacity (S102).
The master battery pack 6 checks its remaining battery capacity, then issues inquiry requests of the remaining battery capacity of slave battery packs 7 (S103). Before the inquiry requests, the master battery pack 6 confirms the existence, quantity, and the like of the slave battery packs 7. The inquiry requests of remaining capacity to the slave battery packs are issued with individual battery pack IDs (YY to ZZ).
8 The battery packs 7, which have individual IDs and are connected to the second through n-th battery bays 4 and which received inquiry requests of remaining capacity, check their own remaining battery capacity and transmit the resultant data 5 to the master battery pack 6 (S104).
The processing means 11 of the master battery pack 6, which received data on the remaining capacity from the slave battery packs 7, processes the data (S105). There are a total of three battery packs. If the master battery pack 6 and two slave battery packs 7 have remaining battery capacities of 50 mAh, 45 mAh, and 55 mAh, respectively, the following process is performed. If the inquiry command from the host control circuit 3 is for remaining battery capacity, a predetermined process sums all data. As a result, 50+45+ 55=150 mAh is transmitted to the host control circuit 3 as status data. It should be noted that this process is only one example and is not limited to the summing process and that various types of processes may be adopted according to the type of monitor command from the host control circuit 3. For example, in the case of a monitor command to detect battery temperature, the maximum value is selected from among the temperature data values and transmitted to the host control circuit 3.
This remaining battery capacity data (150 mAh) is transmitted from the master battery pack 6 to the host control circuit 3 (S106).
The host control circuit 3 may display this remaining battery capacity data on a screen of the PC. If the remaining battery capacity is small, a message may be automatically 9 displayed on the screen to inform the user that charging is required. If the remaining battery capacity is small while an AC adapter is connected to the PC, a control operation may be performed so that charging automatically begins. Although the PC was used as an example, this system is applicable to any electronic equipment as long as functions equivalent to those in the present embodiment are available.
In this sort of system, the condition of a plurality of battery packs can be monitored without using switching devices even if the host control circuit 3 identifies only the master battery 6 having the battery ID.
The host control circuit 3 is applicable in the present invention even with a plurality of IDs, and in such a case, there will be a plurality of master batteries so that more batteries can be monitored. Embodiment 2 In this embodiment, the battery packs are not individually assigned roles of master or slave, and the battery packs themselves have the same structure and performance. The role assignment to the battery packs of master or slave is determined by the battery ID held by the battery bay to which the battery pack is to be physically connected.
The connections of the battery bays having battery IDs and the battery packs are detailed in Fig. 3. Three terminals 13 for battery ID detection signals and one terminal 14 for a master/slave detection signal for a total of four terminals are disposed in the battery bays 4 at positions corresponding to pin arrangements of the battery packs 6, 7. The number of these terminals can be arbitrarily set according to the number of battery packs. Since three terminals are used for the battery ID detection signals in Fig. 3, a maximum of 8 types of IDs can be created from combinations of these three terminals.
If the number of battery packs is increased and it is necessary for more IDs, it is only necessary to increase the number of terminals.
The identification of the battery ID using the battery ID detection terminals 13 will be described. At the first battery bay 4, all the terminals 13 are OPEN to signify ID:XX. The battery pack connected to this first battery bay 4 is identified by the host control circuit 3 through the battery ID detection signals from the three terminals 13. At the second battery bay, the terminals 13 are OPEN, OPEN, and GND to signify ID:M Unlike the previous combination of terminals, the battery pack connected to the second battery bay is not identified by the host control circuit 3. At the n-th battery bay, the terminals are GND, OPEN, and OPEN to signify ID:M Similarly, the battery pack connected here is also not identified by the host control circuit 3. The battery packs connected to the second battery bay and the n-th battery bay are respectively identified as YY and ZZ by the microcomputer 8 of the master battery pack 6.
Next, the identification of master or slave using the master/slave detection terminal 14 will be described. If GND is used as the master detection signal, master or slave can be identified with one terminal. The right terminal of the first battery bay 4 is the master/slave detection terminal 14 and is 11 currently connected to GND so the first battery bay 4 becomes a master connector. The battery pack connected to the first battery bay 4 identifies itself as the master battery pack through the master/slave detection signal from the terminal 14.
The master/slave detection terminals 14 of the second and n-th battery bays are OPEN so these battery bays become slave connectors. The battery packs connected to the second and n-th battery bays identify themselves as slave battery packs through the master/slave detection signals from the terminals 14.
It should be noted that although the battery ID detection terminals and the master/slave detection terminals are separate in this example, the battery ID:XX may also be an identifier combined in advance with master detection.
Since the role of master or slave is determined by the battery bay (connector) to which the battery pack is physically connected, battery packs all having the same structure and performance may be used. Therefore, it is not necessary to use battery packs having two types of control circuits or programs for master and slave. The battery packs may have equivalent performance with their performance controlled according to the master/slave detection signal.
While there has been described what are at present considered to be preferred embodiments of the invention, it will be understood that variouspodifications may be made thereto within the scope of the invention as defined by the claims.
