Recently, there is a tendency toward higher voltage for capacity enlargement in an electric storage system and a battery for mobility use, exploiting a secondary battery. For securing a higher voltage, an arrangement of a tandem connection of a plurality of batteries is used. As a semiconductor device (IC: integrated circuit) monitoring a voltage of a battery cell, there are currently produced various sorts of battery monitor ICs, each of which is able to measure the voltage of a plurality of tandem-connected batteries and to monitor an individual battery cell. This sort of IC has a function in which a plurality of ICs can be stacked in series in series in correspondence with the number of the batteries connected in series (see Non-Patent Literature 1). It is noted that the IC stack function corresponds to a daisy chain connection function for sequentially forwarding, e.g., command/data to respective neighboring ICs.
During a time of forwarding command or data, a chip select input pin (CSB1) of the IC10 is set to an activated state (e.g., LOW voltage), under control by a microcomputer, not shown. During this forwarding period, the command or data is sent from one stage to a following stage in synchronization with a clock signal. It is noted that, in the example shown in
In the stackable ICs, it is necessary to effect functionality setting of each of the ICs stacked in order to send data of such as cell voltage that the IC acquired to e.g., a microcomputer.
The functionality setting of the ICs in many cases is by a hardware using an IC peripheral circuit. More specifically, a functionality setting pin of the IC is pulled up to a power supply voltage (VDD) or pulled down to a ground (GND) potential.
The IC 13 that is connected to the microcomputer 2, is a master IC, with the other IC 13 and IC 12 being slave ICs. In the IC 13, functioning as the master IC, a setting pin that sets the function of the IC 13 and a power supply voltage (VDD) are connected together by a circuit (wiring) 43. In the IC 13 and IC 12, functioning as slaves ICs, GND and the setting pins are connected together by circuits (wirings) 41 and 42, respectively. It is noted that, in case each of the IC 11 to IC 13 is a battery stack monitor IC of

Moreover, according to the present invention, the function of the IC may automatically be set simply by connecting boards, each having an IC mounted.

In addition, the number of the ICs stacked together may be increased or decreased with ease. The following describes exemplary embodiments of the present invention.
In the board 100, the GND pin 105, master slave setting pin 104 and the VDD pin 103 are respectively connected via wirings 102A, 102B and 102C on the board 100 to terminals 106A, 106B and 106C of the connector 106. The connector 107 has its terminals 107A and 107B arranged at locations that correspond respectively to the terminals 106A and 106B of the opposing connector 106. The terminals 107A and 107B of the connector 107 are connected together via a circuit (wiring) 108 provided on the board 100. By the way, a reference number 107C shown in the connector 107 represents a location that corresponds to the location of the terminal 106C of the connector 106. It is noted that, if a terminal, such as a pin, is provided at a location of 107C, such terminal or pin is unconnected (open), with respect to the circuit provided on the board 100, and hence no terminal or pin needs to be provided at the location of 107C (It does not matter whether such terminal or pin is actually provided). If the connector 107 is provided with a receptacle (terminal), such a receptacle that holds a pin that is connected to the connector 107, may be provided at a location indicated by 107c.
Referring to
The master slave setting pin 104 and the GND pin 105 of the board 1001 are connected together via the connector 1061 of the board 101, set of cables 1091, connector 1072 of the board 1002 and a circuit (connection circuit) provided on the board 1002. By connecting the connector 1061 of the board 1001 and the connector 1072 of the board 1002, the IC 1011 of the board 1001 is set to a slave function.
Furthermore, by connecting a connector 1062 of the board 1002 to a connector 1073 of the board 1003, the master slave setting pin 104 and the GND pin 105 of the IC 1012 of the board 1002 are connected together via the connector 1062 of the board 1002 and a circuit 1083 on the board 1003. Hence, the IC 1012 of the board 1002 is set to a slave function.
The control board 111 includes a microcomputer 2 that performs communication with the ICs 1011 to 1012 mounted on the boards 1001 to 1003 to control transmission of commands, data collection and the like. The control board 111 also includes a connector 1074 on a side thereof facing a neighboring board 1003 so that the connector will correspond to a connector 1063 of the board 1003. Two of terminals in the connector 1074 are connected together via a circuit (connection circuit) 1084, (which is a wiring) provided on the control board 111.
To connect the board 1003 and the control board 111 together, the connector 1063 of the board 1003 is connected via a set of cables 1093 to the connector 1074 of the control board 111. The connector 1074 of the control board 111 has its terminals connected such that the master slave setting pin 104 and the VDD pin 103 of the IC 1013 of the board 1003 are connected together, via the connector 1063 of the board 1003, set of cables 1093, connector 1074 of the control board 111 and the circuit 1084 arranged on the control board 111. It is noted that the connector 1074 provided on the control board 111, corresponds to a configuration in which a terminal at a location of 107C in the connector 107 of
By connecting the connector 1063 of the board 1003 and the connector 1074 of the control board 111 together, the functionality of the IC 1013, provided on the board 1003, is set to that of a master (the function to directly connect to the microcomputer 2).
In the board 1001 arranged on an end, the terminals of a connector 1071, disposed on a side of the board opposite to its side facing the neighboring board 1002, are left open, because the connector lacks a counterpart connector to which the connector is to be connected.
The above described exemplary embodiment uses the sets of cables 109 to wiring the connectors 106 and 107 of the neighboring boards facing each other. However, the neighboring boards may also be connected by means other than the cables. For example, a card edge connector may also be used for connecting the neighboring boards. Or, the connector 106 may be provided with a through-pin which may fit to a receptacle of the counterpart connector 107. In this case, receptacles of the connectors 107A to 107C of the connector 107 are provided in association with pins of the terminals 106A to 106C of the connector 106 of the counterpart board. If the circuit configuration is the same from one board to another and the neighboring boards are connectable by any other means, the configuration of connection between the neighboring boards is not limited to the connection making use of the connectors. That is, it may not be strictly necessary to provide the connectors.
In the exemplary embodiment 1, function setting of the IC 101 (setting of the master function or the slave function) can be carried out in accordance with connection of the boards, so that, in the exemplary embodiment 1, it is unnecessary to modify a circuit or change over a switch in correspondence with the IC function to render it possible to reduce the number of design processes as well as costs.
Moreover, in the exemplary embodiment 1, the number of ICs stacked together may be changed by simply increasing or decreasing the number of the boards to be connected. If, for example, the IC is a battery monitor IC, the number of serially connected cells (batteries) to be monitored can be freely changed (adapted for scalability).

The VDD pin 203, top setting pin 204 and GND pin 205 of the IC 201 are respectively connected via wirings 202A, 202B and 202C of the board 200 to terminals 207A, 207B and 207C of the connector 207. The terminals 206 and 206C of the connector 206 that are respectively opposed to the terminals 207B and 207C of the connector 207, are connected by a circuit (connection circuit) 208 on the board 200. There is no need to provide a terminal (connection terminal) at a location indicated by a reference number 206A of the connector 206 since such a terminal, if provided, remains unconnected with respect to the circuit provided on the board 200. However, when the connector 206 is provided with a receptacle, a receptacle (connection terminal) may be well provided on accommodate a pin for connection at a location indicated by a reference number 206A.
