Description
【0001】[0001]
本考案は、電池部の充電温度を検出する温度検出部とこの電池部の残存容量を 検出する残量検出部とをその内部に備えたバッテリに関するものである。 The present invention relates to a battery including therein a temperature detecting unit that detects a charging temperature of a battery unit and a remaining amount detecting unit that detects a remaining capacity of the battery unit.
【0002】[0002]
ニッケル水素電池は充電容量が大きく長時間使えるという利点がある。ただし この電池は温度に応じた充電をする必要があるので、これを使ったバッテリは、 図4に示すように電池部2の充電温度を検出して温度検出信号3aを出力するサ ーミスタ3と、こうして得た温度検出信号3aを充電装置に供給するための端子 4とをその内部に備える。もちろん、充電装置にはサーミスタ3の出力3aを受 けて充電を最適にする回路が組み込まれる。なお、5a,5bは電池2につない だ充放電端子である。 The nickel-hydrogen battery has the advantage that it has a large charge capacity and can be used for a long time. However, since this battery needs to be charged according to the temperature, the battery using this battery has a thermistor 3 that detects the charging temperature of the battery unit 2 and outputs a temperature detection signal 3a as shown in FIG. A terminal 4 for supplying the temperature detection signal 3a thus obtained to the charging device is provided therein. Of course, the charging device incorporates a circuit that receives the output 3a of the thermistor 3 and optimizes charging. Note that 5a and 5b are charge / discharge terminals connected to the battery 2.
【0003】 さて最近、装置の表示部(例えばビデオカメラのビューファインダ)にバッテ リの電池残量を表示する技術がある。この技術を採用したバッテリは、図5に示 すように電池部2の残存容量を検出して残量検出信号6aを出力する残量検出部 6と、こうして得た残量検出信号6aを装置に供給するための端子7とをその内 部に備えている。もちろん、装置には残量検出部6の出力6aを表示データに変 換して表示する回路が組み込まれる。なお、残量検出部6の具体的構成はここで は省略してある。By the way, recently, there is a technique of displaying the remaining battery level of a battery on the display unit (for example, a viewfinder of a video camera) of the apparatus. As shown in FIG. 5, a battery adopting this technology uses a remaining amount detecting unit 6 that detects the remaining capacity of the battery unit 2 and outputs a remaining amount detecting signal 6a, and a remaining amount detecting signal 6a obtained in this way. And a terminal 7 for supplying to the inside. Of course, the device incorporates a circuit for converting the output 6a of the remaining amount detector 6 into display data and displaying the converted data. The specific structure of the remaining amount detector 6 is omitted here.
【0004】[0004]
上記2つのことを組み合わせた場合、すなわち、ニッケル水素電池を使ったバ ッテリで電池残量を装置の表示部に表示する場合は、図6に示すバッテリ10の ようにサーミスタ3と残量検出部6とをもたせ、温度検出信号3aを充電装置に 供給するための端子4と残量検出信号6aを装置に供給するための端子7とをそ れぞれ用意した構成を考えることができる。しかし、このように端子4,7を個 々に設けると接点不良が起こる確率が大きくなり、バッテリ10の信頼性が低く なりやすい。 When the above two are combined, that is, when the battery level using a nickel-hydrogen battery is displayed on the display section of the device, the thermistor 3 and the remaining level detection section like the battery 10 shown in FIG. 6, a terminal 4 for supplying the temperature detection signal 3a to the charging device and a terminal 7 for supplying the remaining amount detection signal 6a to the charging device can be considered. However, if the terminals 4 and 7 are individually provided in this way, the probability of contact failure increases, and the reliability of the battery 10 tends to decrease.

本考案者は電池部2の充電時に温度検出信号3aが必要で、電池部2の放電時 に残量検出信号6aが必要で、これら両方を同時に必要としないことに着目した 。 そこで本考案は上述した課題を解消するものであり、電池部の充電温度を検出し て温度検出信号を出力する温度検出部と、前記電池部の残存容量を検出して残量 検出信号を出力する残量検出部と、前記電池部の充放電状態を判別して充放電判 別信号を出力する制御部と、前記充放電判別信号に応じて前記温度検出信号と前 記残量検出信号とを切り換え出力するスイッチとを備えたバッテリであって、前 記電池部の充電時、前記スイッチは前記温度検出信号を選択出力し、前記電池部 の放電時、前記スイッチは前記残量検出信号を選択出力することを特徴とするバ ッテリを提供するものである。 The present inventor has noticed that the temperature detection signal 3a is required when the battery unit 2 is charged, the remaining amount detection signal 6a is required when the battery unit 2 is discharged, and both of them are not required at the same time. Therefore, the present invention solves the above-mentioned problems by providing a temperature detection unit that detects the charging temperature of the battery unit and outputs a temperature detection signal, and a remaining capacity detection unit that detects the remaining capacity of the battery unit and outputs a remaining amount detection signal. A remaining amount detection unit, a control unit that determines the charge / discharge state of the battery unit and outputs a charge / discharge determination signal, and the temperature detection signal and the remaining amount detection signal described above according to the charge / discharge determination signal. And a switch for switching and outputting the battery, the switch selectively outputs the temperature detection signal when the battery unit is charged, and the switch outputs the remaining amount detection signal when the battery unit is discharged. It provides a battery that features selective output.

以下、本考案を図面に沿って説明する。 Hereinafter, the present invention will be described with reference to the drawings.
【0007】 図1は本考案のバッテリの一実施例を示すブロック図、図2は要部となる制御 部を示すブロック図、図3は残量検出部と制御部の他例を示す図である。なお、 従来例と同一構成部には同一符号を付してある。FIG. 1 is a block diagram showing an embodiment of the battery of the present invention, FIG. 2 is a block diagram showing a main control unit, and FIG. 3 is a diagram showing another example of a remaining amount detection unit and a control unit. is there. The same components as those in the conventional example are designated by the same reference numerals.
【0008】 図1に示すバッテリ1は電池部(例えばニッケル水素電池)2の温度を検出す るサーミスタ(温度検出部)3と、電池2の残量を検出する残量検出部6とを備 える。The battery 1 shown in FIG. 1 includes a thermistor (temperature detection unit) 3 that detects the temperature of a battery unit (for example, a nickel hydrogen battery) 2 and a remaining amount detection unit 6 that detects the remaining amount of the battery 2. Get
【0009】 7は、温度検出信号3aと残量検出信号6aとを切り換え出力し、いずれか一 方を端子8まで導くスイッチである。スイッチ7内ではサーミスタ3につながっ た接点71と残量検出部6につながった接点72とが、端子8につながったスイ ッチ片73で選択的に切り換えられる。このスイッチ7は制御端子に次述する制 御部9の制御信号を受けてスイッチ片73の切換動作が制御される。Reference numeral 7 is a switch for switching and outputting the temperature detection signal 3 a and the remaining amount detection signal 6 a, and guiding either one to the terminal 8. In the switch 7, the contact 71 connected to the thermistor 3 and the contact 72 connected to the remaining amount detector 6 are selectively switched by the switch piece 73 connected to the terminal 8. The switch 7 receives a control signal from the control unit 9 described below at its control terminal to control the switching operation of the switch piece 73.
【0010】 制御部9は、電池部2の充放電状態を判別して充放電判別信号となる制御信号 を出力するものであり、例えば図2に示すように検出部91と信号発生部92と から構成される。The control unit 9 determines the charging / discharging state of the battery unit 2 and outputs a control signal serving as a charging / discharging determination signal. For example, as shown in FIG. 2, a detection unit 91 and a signal generation unit 92 are provided. Composed of.
【0011】 検出部91は点Aを基準とした点Bの電位を出力する。電池部2の充電時には X1方向に電流が流れるので、点Aの方が点Bよりも電位が高く検出部91の出 力は負の値になる。電池部2の放電時にはX2方向に電流が流れるので、点Aよ りも点Bの方が電位が高く検出部91の出力は正の値になる。The detection unit 91 outputs the potential at the point B with reference to the point A. Since a current flows in the X1 direction when the battery unit 2 is charged, the potential at the point A is higher than that at the point B, and the output of the detection unit 91 has a negative value. Since a current flows in the X2 direction when the battery unit 2 is discharged, the potential at the point B is higher than at the point A and the output of the detection unit 91 has a positive value.
【0012】 信号発生部92は検出部91の出力が正か負かに応じて制御信号を出力する。 検出部91の出力が負(電池部2の充電時)のとき、信号発生部92はスイッチ 片73を接点71につなげる制御信号をスイッチ7の制御端子に出力する。電流 検出部91の出力が正(電池部2の放電時)のとき、スイッチ片73を接点72 につなげる制御信号をスイッチ7の制御端子に出力する。The signal generator 92 outputs a control signal depending on whether the output of the detector 91 is positive or negative. When the output of the detection unit 91 is negative (when the battery unit 2 is being charged), the signal generation unit 92 outputs a control signal for connecting the switch piece 73 to the contact 71 to the control terminal of the switch 7. When the output of the current detecting unit 91 is positive (when the battery unit 2 is discharging), a control signal for connecting the switch piece 73 to the contact 72 is output to the control terminal of the switch 7.
【0013】 このようにバッテリ1を構成すれば、電池部2の充電時にスイッチ7のスイッ チ片73は図示するように接点71につながり、また放電時にスイッチ片73は 二点鎖線で示すように接点72につながる。これにより、電池部2の充電時にサ ーミスタ3から出力される温度検出信号3aを端子8に導くことができ、また電 池2の放電時に残量検出部6から出力される残量検出信号6aを端子8に導くこ とができる。If the battery 1 is configured in this way, the switch piece 73 of the switch 7 is connected to the contact 71 as shown in the figure when the battery section 2 is charged, and the switch piece 73 is shown in the two-dot chain line during discharge. Connects to contact 72. Thereby, the temperature detection signal 3a output from the thermistor 3 when the battery unit 2 is charged can be guided to the terminal 8, and the remaining amount detection signal 6a output from the remaining amount detection unit 6 when the battery 2 is discharged. Can be led to the terminal 8.
【0014】 このバッテリ1では、温度検出信号3aまたは残量検出信号6aを選択できる よう構成したので、これらを装置に供給するには一の端子8を用意すればよく、 端子を個々に設けた場合よりも接点不良が起こる確率が小さくなり、信頼性が高 まるという利点がある。Since the battery 1 is configured so that the temperature detection signal 3a or the remaining amount detection signal 6a can be selected, one terminal 8 may be prepared to supply these to the apparatus, and the terminals are individually provided. Compared with the case, there is an advantage that the probability of contact failure is reduced and the reliability is improved.
【0015】 もちろん、充電装置および使用する装置には端子8に対応する端子をそれぞれ 設ければ良いのは言うまでもない。Needless to say, the charging device and the device to be used may be provided with terminals corresponding to the terminals 8, respectively.
【0016】 なお、上記説明では残量検出部6と制御部9とを別構成にして説明したが、図 3に示すように残量検出部6が上記検出部91と同様な検出部61とCPUを使 った演算部62とからなる場合は、検出部61を制御部9の一部とした構成を考 えても良い。In the above description, the remaining amount detecting unit 6 and the control unit 9 are described separately, but as shown in FIG. 3, the remaining amount detecting unit 6 includes a detecting unit 61 similar to the detecting unit 91. In the case of the operation unit 62 using a CPU, a configuration in which the detection unit 61 is part of the control unit 9 may be considered.
【0017】[0017]
以上の説明からわかるように本考案のバッテリでは、温度検出信号または残量 検出信号を選択できるよう構成したので、これらを装置に供給するには一の端子 を用意すればよく、端子を個々に設けた場合よりも接点不良が起こる確率が小さ くなり、信頼性が高まるという効果がある。 As can be seen from the above description, the battery of the present invention is configured so that the temperature detection signal or the remaining amount detection signal can be selected. Therefore, in order to supply these to the device, one terminal can be prepared and each terminal can be individually supplied. The probability that a contact failure will occur is smaller than the case where it is provided, and there is an effect that reliability is improved.
