Description

本発明はバッテリ付き機器に関する。 The present invention relates to a battery with equipment.

停電や電源変動などの電源トラブルに対処するために、電源とコンピュータなどの負荷との間に無停電電源装置を接続する方法がある。この無停電電源装置は、停電や電源変動などの電源トラブルが発生すると、内部バッテリを電源として負荷に電力を供給することで、負荷に供給される電力を安定に維持することができる。
図９は、無停電電源装置の概略構成を示すブロック図である。 There is a method of connecting an uninterruptible power supply between a power source and a load such as a computer in order to cope with a power source trouble such as a power failure or power fluctuation. This uninterruptible power supply can stably maintain the power supplied to the load by supplying power to the load using the internal battery as a power source when a power trouble such as a power failure or power fluctuation occurs.
FIG. 9 is a block diagram illustrating a schematic configuration of the uninterruptible power supply.

図９において、無停電電源装置には、電力を貯蔵するバッテリ部１０４が設けられ、バッテリ部１０４はコネクタ１０５を介して電力変換回路部１０２に接続されている。なお、電力変換回路部１０２には、コンバータ回路やチョッパ回路などが搭載され、スイッチング動作によって直流を交流に変換することができる。ここで、バッテリ部１０４からはバッテリ部１０４の正極端子および負極端子を電力変換回路部１０２にそれぞれ接続するための給電線１０６、１０７が引き出され、バッテリ部１０４は給電線１０６、１０７を介して電力変換回路部１０２のプリント基板に接続される。 In FIG. 9, the uninterruptible power supply is provided with a battery unit 104 that stores electric power, and the battery unit 104 is connected to the power conversion circuit unit 102 via a connector 105 . Note that the power conversion circuit unit 102 includes a converter circuit, a chopper circuit, and the like, and can convert direct current into alternating current through a switching operation. Here, power supply lines 106 and 107 for connecting the positive terminal and the negative terminal of the battery part 104 to the power conversion circuit part 102 are drawn out from the battery part 104. The battery part 104 is connected via the power supply lines 106 and 107. It is connected to the printed circuit board of the power conversion circuit unit 102.

そして、通常時には、商用電源１０１から負荷１０３に電力が供給される。そして、停電や電源変動などの電源トラブルが発生すると、負荷１０３への電力の供給経路がバッテリ部１０４側に切り替えられ、バッテリ部１０４から供給される直流が電力変換回路部１０２にて交流に変換された後、負荷１０３に電力が供給される。
ここで、バッテリ部１０４に搭載されるバッテリとしては、正極と負極とが交互に積層された構造、すなわち、セルが一方向に直列に積層された構造が広く用いられている。 In normal times, power is supplied from the commercial power supply 101 to the load 103. When a power supply trouble such as a power failure or power fluctuation occurs, the power supply path to the load 103 is switched to the battery unit 104 side, and the direct current supplied from the battery unit 104 is converted into an alternating current by the power conversion circuit unit 102. After that, electric power is supplied to the load 103.
Here, as the battery mounted on the battery unit 104, a structure in which positive electrodes and negative electrodes are alternately stacked, that is, a structure in which cells are stacked in series in one direction is widely used.

図１０（ａ）は従来のバッテリの概略構成を模式的に示す斜視図、図１０（ｂ）は図１０（ａ）のバッテリの概略構成を模式的に示す平面図、図１０（ｃ）は図１０（ａ）のバッテリの給電線の電圧分布を示す図である。
図１０において、長さＬのバッテリ１１１には、複数のセル１１２が設けられ、セル１１２は一方向に直列に積層されている。ここで、バッテリ１１１内には、両端のセル１１２の正極と負極にそれぞれ接続された正極内部端子Ｂ１１および負極内部端子Ｂ１１´が設けられるとともに、バッテリ１１１外には、バッテリ１１１を電力変換回路部１０２に接続するための正極外部端子Ａ１１および負極外部端子Ａ１１´が設けられている。 FIG. 10A is a perspective view schematically showing a schematic configuration of a conventional battery, FIG. 10B is a plan view schematically showing the schematic configuration of the battery in FIG. 10A, and FIG. It is a figure which shows the voltage distribution of the feeder of the battery of Fig.10 (a).
In FIG. 10, a battery 111 having a length L is provided with a plurality of cells 112, and the cells 112 are stacked in series in one direction. Here, in the battery 111, a positive electrode internal terminal B11 and a negative electrode internal terminal B11 ′ connected to the positive electrode and the negative electrode of the cell 112 at both ends are provided, and the battery 111 is connected to the power conversion circuit unit outside the battery 111. A positive external terminal A 11 and a negative external terminal A 11 ′ for connection to 102 are provided.

ここで、バッテリ１１１の正極内部端子Ｂ１１は負極内部端子Ｂ１１´に対して反対側に配置されるとともに、バッテリ１１１の正極外部端子Ａ１１は負極外部端子Ａ１１´側に配置されている。そして、正極内部端子Ｂ１１と正極外部端子Ａ１１とは給電線１１３を介して接続され、負極内部端子Ｂ１１´と負極外部端子Ａ１１´とは給電線１１４を介して接続されている。   Here, the positive electrode internal terminal B11 of the battery 111 is disposed on the opposite side to the negative electrode internal terminal B11 ′, and the positive electrode external terminal A11 of the battery 111 is disposed on the negative electrode external terminal A11 ′ side. The positive electrode internal terminal B11 and the positive electrode external terminal A11 are connected via a power supply line 113, and the negative electrode internal terminal B11 ′ and the negative electrode external terminal A11 ′ are connected via a power supply line 114.

ここで、給電線１１３のインピーダンスは、正極外部端子Ａ１１で最も低く、正極内部端子Ｂ１１で最も高くなる。そのため、図９の電力変換回路部１０２のスイッチング素子のスイッチング動作などで発生したノイズが高周波電流としてバッテリ１１１に伝わると、バッテリ１１１の正極内部端子Ｂ１１で反射が起こり、この反射波が入射波と重ね合わされることによって、図１０（ｃ）に示すように、給電線１１３上で１／４波長を給電線長さｌとする定在波が発生し、給電線長さｌによって波長が決まる放射ノイズが発生する。 Here, the impedance of the feeder 113 is lowest at the positive external terminal A11 and highest at the positive internal terminal B11. Therefore, when noise generated by the switching operation of the switching element of the power conversion circuit unit 102 in FIG. 9 is transmitted to the battery 111 as a high-frequency current, reflection occurs at the positive electrode internal terminal B11 of the battery 111, and this reflected wave becomes an incident wave. As a result of the superposition, as shown in FIG. 10C, a standing wave having a quarter wavelength of the feed line length l is generated on the feed line 113, and the wavelength is determined by the feed line length l. Noise is generated.

この給電線長さｌと放射ノイズの波長λとの関係は、以下の式で表すことができる。
ｌ＝１／４λ （１）
λ＝Ｃ／（ｆ√（εｒμｒ）） （２）
ｆ＝Ｃ／（４ｌ√（εｒμｒ）） （３）
ただし、
Ｃ：光速（＝３×１０８）［ｍ／ｓｅｃ］
ｌ：給電線長さ［ｍ］
ｆ：共振周波数（定在波が発生する周波数）
λ：波長［ｍ］
εｒ：給電線の比誘電率
μｒ：給電線の比透磁率
そして、ノイズ規制値が定められている上限の周波数は機器の種類によって決められている。
また、無停電電源装置に用いられるバッテリは、その出力電圧を大きくするために、複数台を直列接続することがある。 The relationship between the feeder line length l and the wavelength λ of the radiation noise can be expressed by the following equation.
l = 1 / 4λ (1)
λ = C / (f√ (ε r μ r )) (2)
f = C / (4l√ (ε r μ r )) (3)
However,
C: speed of light (= 3 × 10 8 ) [m / sec]
l: Feed line length [m]
f: Resonance frequency (frequency at which standing wave is generated)
λ: wavelength [m]
[epsilon] r : relative dielectric constant of the feeder line [mu] r : relative permeability of the feeder line The upper limit frequency at which the noise regulation value is determined is determined by the type of device.
Moreover, the battery used for an uninterruptible power supply device may connect two or more series in series in order to enlarge the output voltage.

図１１（ａ）は従来のバッテリの概略構成のその他の例を模式的に示す斜視図、図１１（ｂ）は図１１（ａ）のバッテリの概略構成を模式的に示す平面図、図１１（ｃ）は図１１（ａ）のバッテリの給電線の電圧分布を示す図である。
図１１において、バッテリ１２１ａ、１２１ｂには、複数のセル１２２ａ、１２２ｂがそれぞれ設けられ、セル１２２ａ、１２２ｂはそれぞれ一方向に直列に積層されている。ここで、バッテリ１２１ａ内には、一端のセル１２２ａの正極に接続された正極内部端子Ｂ１２が設けられるとともに、バッテリ１２１ａ外には、バッテリ１２１ａの正極を電力変換回路部１０２に接続するための正極外部端子Ａ１２が設けられている。また、バッテリ１２１ｂ内には、一端のセル１２２ｂの負極に接続された負極内部端子Ｂ１２´が設けられるとともに、バッテリ１２１ｂ外には、バッテリ１２１ｂの負極を電力変換回路部１０２に接続するための負極外部端子Ａ１２´が設けられている。そして、バッテリ１２１ａの他端のセル１２２ａの負極とバッテリ１２１ｂの他端のセル１２２ｂの正極とを接続導体１２４を介して接続することで、バッテリ１２１ａ、１２１ｂは互いに直列接続されている。 FIG. 11A is a perspective view schematically showing another example of the schematic configuration of the conventional battery, FIG. 11B is a plan view schematically showing the schematic configuration of the battery in FIG. (C) is a figure which shows the voltage distribution of the feeder of the battery of Fig.11 (a).
In FIG. 11, batteries 121a and 121b are provided with a plurality of cells 122a and 122b, respectively, and the cells 122a and 122b are respectively stacked in series in one direction. Here, a positive internal terminal B12 connected to the positive electrode of the cell 122a at one end is provided in the battery 121a, and a positive electrode for connecting the positive electrode of the battery 121a to the power conversion circuit unit 102 outside the battery 121a. An external terminal A12 is provided. In addition, a negative electrode internal terminal B12 ′ connected to the negative electrode of the cell 122b at one end is provided in the battery 121b, and a negative electrode for connecting the negative electrode of the battery 121b to the power conversion circuit unit 102 outside the battery 121b. An external terminal A12 ′ is provided. The batteries 121a and 121b are connected in series by connecting the negative electrode of the cell 122a at the other end of the battery 121a and the positive electrode of the cell 122b at the other end of the battery 121b via the connection conductor 124.

ここで、バッテリ１２１ａの正極内部端子Ｂ１２は、バッテリ１２１ｂの負極内部端子Ｂ１２´に対して反対側に配置されるとともに、バッテリ１２１ａの正極外部端子Ａ１２は、バッテリ１２１ｂの負極外部端子Ａ１２´側に配置されている。そして、正極内部端子Ｂ１２と正極外部端子Ａ１２とは給電線１２３を介して接続され、負極内部端子Ｂ１２´と負極外部端子Ａ１２´とは給電線１２４を介して接続されている。   Here, the positive internal terminal B12 of the battery 121a is disposed on the opposite side to the negative internal terminal B12 ′ of the battery 121b, and the positive external terminal A12 of the battery 121a is on the negative external terminal A12 ′ side of the battery 121b. Has been placed. The positive electrode internal terminal B12 and the positive electrode external terminal A12 are connected via a power supply line 123, and the negative electrode internal terminal B12 ′ and the negative electrode external terminal A12 ′ are connected via a power supply line 124.

ここで、給電線１２３のインピーダンスは、正極外部端子Ａ１２で最も低く、正極内部端子Ｂ１２で最も高くなる。また、給電線１２４のインピーダンスは、正極外部端子Ａ１２’で最も低く、正極内部端子Ｂ１２’で最も高くなる。そのため、図９の電力変換回路部１０２のスイッチング素子のスイッチング動作などで発生したノイズが高周波電流としてバッテリ１２１ａ、１２１ｂに伝わると、バッテリ１２１ａ、１２１ｂの正極内部端子Ｂ１２、Ｂ１２’でそれぞれ反射が起こり、この反射波が入射波と重ね合わせられることによって、図１１（ｃ）に示すように、給電線１２３、１２４上で１／４波長を給電線長さｌとする定在波がそれぞれ発生し、給電線長さｌによって波長が決まる放射ノイズがそれぞれ発生する。 Here, the impedance of the feeder 123 is lowest at the positive external terminal A12 and highest at the positive internal terminal B12. The impedance of the feeder 124 is lowest at the positive external terminal A12 ′ and highest at the positive internal terminal B12 ′. Therefore, when noise generated by the switching operation of the switching element of the power conversion circuit unit 102 in FIG. 9 is transmitted to the batteries 121a and 121b as high-frequency current, reflection occurs at the positive internal terminals B12 and B12 ′ of the batteries 121a and 121b, respectively. By superimposing this reflected wave on the incident wave, as shown in FIG. 11 (c), standing waves having a 1/4 wavelength as the feed line length l are generated on the feed lines 123 and 124, respectively. Then, radiation noise whose wavelength is determined by the feed line length l is generated.

また、例えば、特許文献１には、バッテリの給電線上で生じる定在波に起因する放射ノイズを抑制するために、バッテリの端部とグランドとを容量結合により高周波的に接続し、アンテナとして機能する給電線の端部の電圧をゼロにする方法が開示されている。 Further, for example, in Patent Document 1, in order to suppress radiation noise caused by a standing wave generated on the battery power supply line, the end of the battery and the ground are connected at high frequency by capacitive coupling, and function as an antenna. A method is disclosed in which the voltage at the end of the feeder line is zero.

しかしながら、特許文献１に開示された方法では、バッテリの端部とグランドとを容量結合させる必要があり、その容量結合が装置の構造上困難である場合には、バッテリの給電線上で生じる定在波に起因する放射ノイズを抑制することができないという問題があった。
そこで、本発明の目的は、バッテリの端部とグランドとを容量結合させることなく、給電線上で生じる定在波に起因する放射ノイズの影響を低減することが可能なバッテリ付き機器を提供することである。 However, in the method disclosed in Patent Document 1, it is necessary to capacitively couple the end portion of the battery and the ground, and when the capacitive coupling is difficult due to the structure of the device, the standing that occurs on the power supply line of the battery. There has been a problem that radiation noise caused by waves cannot be suppressed.
An object of the present invention, without capacitive coupling and an end portion of the battery and ground, to provide a battery with equipment capable of reducing the influence of radiation noise due to the standing wave occurring in the feed line That is.

以上説明したように、本発明によれば、バッテリの給電線の長さを短くすることで、給電線上で生じる定在波に起因する放射ノイズについてノイズ規制値で定められている上限の周波数よりも高くすることが可能となり、バッテリの端部とグランドとを容量結合させることなく、給電線上で生じる定在波に起因する放射ノイズの影響を低減することが可能となる。 As described above, according to the present invention, by shortening the length of the battery power supply line, the radiation noise caused by the standing wave generated on the power supply line is more than the upper limit frequency defined by the noise regulation value. Therefore, it is possible to reduce the influence of radiation noise caused by the standing wave generated on the feeder line without capacitively coupling the end of the battery and the ground.

以下、本発明の実施形態に係るバッテリについて図面を参照しながら説明する。なお、以下の説明では、放射ノイズについてのノイズ規制値が１ＧＨｚ以下の周波数に対して設けられ、バッテリ内部のセルから外部に引き出された給電線の比誘電率εrが３．４、比透磁率μrが１の場合を例にとる。この例では、給電線長さｌが約４．１ｃｍ以上になると、１ＧＨｚ以下の周波数で定存波が発生する。 Hereinafter, a battery according to an embodiment of the present invention will be described with reference to the drawings.

In this example, when the feed line length l is about 4.1 cm or more, a standing wave is generated at a frequency of 1 GHz or less.

図１は、本発明の第１実施形態に係るバッテリの概略構成を模式的に示す斜視図である。
図１において、バッテリ１１には、複数のセル１２が設けられ、セル１２は一方向に直列に積層されている。ここで、バッテリ１１内には、両端のセル１２の正極と負極にそれぞれ接続された正極内部端子Ｂ１および負極内部端子Ｂ１´が設けられるとともに、バッテリ１１外には、バッテリ１１を図９の電力変換回路部１０２に接続するための正極外部端子Ａ１および負極外部端子Ａ１´が設けられている。 FIG. 1 is a perspective view schematically showing a schematic configuration of the battery according to the first embodiment of the present invention.
In FIG. 1, a battery 11 is provided with a plurality of cells 12, and the cells 12 are stacked in series in one direction. Here, a positive electrode internal terminal B1 and a negative electrode internal terminal B1 ′ connected to the positive electrode and the negative electrode of the cell 12 at both ends are provided in the battery 11, and the battery 11 is connected to the power of FIG. A positive external terminal A1 and a negative external terminal A1 ′ for connection to the conversion circuit unit 102 are provided.

ここで、バッテリ１１の正極内部端子Ｂ１は負極内部端子Ｂ１´に対して反対側に配置されるとともに、バッテリ１１の正極外部端子Ａ１は負極外部端子Ａ１´に対して反対側に配置され、正極内部端子Ｂ１および正極外部端子Ａ１はバッテリ１１の一端に配置され、負極内部端子Ｂ１´および負極外部端子Ａ１´はバッテリ１１の他端に配置される。そして、正極内部端子Ｂ１と正極外部端子Ａ１とは給電線１３を介して接続され、負極内部端子Ｂ１´と負極外部端子Ａ１´とは給電線１４を介して接続されている。   Here, the positive electrode internal terminal B1 of the battery 11 is disposed on the opposite side to the negative electrode internal terminal B1 ′, and the positive electrode external terminal A1 of the battery 11 is disposed on the opposite side to the negative electrode external terminal A1 ′. The internal terminal B 1 and the positive external terminal A 1 are disposed at one end of the battery 11, and the negative internal terminal B 1 ′ and the negative external terminal A 1 ′ are disposed at the other end of the battery 11. The positive electrode internal terminal B1 and the positive electrode external terminal A1 are connected via the power supply line 13, and the negative electrode internal terminal B1 ′ and the negative electrode external terminal A1 ′ are connected via the power supply line 14.

これにより、バッテリ１１の長さＬに依存することなく、給電線１３、１４の長さｌを決めることができ、給電線１３、１４の長さｌを短くすることが可能となることから、給電線１３、１４上で生じる定在波に起因する放射ノイズについて規制値で定められている上限の周波数よりも高くすることが可能となり、給電線１３、１４上で生じる定在波に起因する放射ノイズの影響を低減することが可能となる。 Thereby, without depending on the length L of the battery 11, the length l of the feeder lines 13 and 14 can be determined, and the length l of the feeder lines 13 and 14 can be shortened. The radiation noise caused by the standing waves generated on the feeder lines 13 and 14 can be made higher than the upper limit frequency defined by the regulation value, and is caused by the standing waves generated on the feeder lines 13 and 14. It becomes possible to reduce the influence of radiation noise.

例えば、図１０の構成では、給電線１１３の長さｌは給電線１１４の長さよりも長くなり、バッテリ１１の長さＬが５ｃｍとすると、給電線１１３の長さｌも５ｃｍとなり、（３）式から８１３ＭＨｚ以下の周波数で定在波が発生する。
これに対して、図１の構成では、給電線１３の長さｌを給電線１４の長さと等しくすることができ、バッテリ１１の長さＬが５ｃｍであっても、給電線１３の長さｌを３ｃｍとすることが可能となる。このため、（３）式から定在波が発生する周波数を１．３６ＧＨｚとすることができ、ノイズ規制値が設けられている１ＧＨｚ以下の周波数以下の周波数では、定在波の発生を抑えることができる。 For example, in the configuration of FIG. 10, the length l of the power supply line 113 is longer than the length of the power supply line 114. If the length L of the battery 11 is 5 cm, the length l of the power supply line 113 is also 5 cm. ) To generate a standing wave at a frequency of 813 MHz or less.
On the other hand, in the configuration of FIG. 1, the length l of the power supply line 13 can be made equal to the length of the power supply line 14, and the length of the power supply line 13 can be obtained even when the length L of the battery 11 is 5 cm. l can be 3 cm. For this reason, the frequency at which the standing wave is generated can be set to 1.36 GHz from the equation (3), and the generation of the standing wave is suppressed at a frequency equal to or lower than the frequency of 1 GHz or less where the noise regulation value is provided.

これにより、バッテリ９１の長さに依存することなく、給電線９３、９４の長さｌを決めることができ、給電線９３、９４の長さｌを短くすることが可能となることから、給電線９３、９４上で生じる定在波に起因する放射ノイズの影響を低減することが可能となるとともに、単一のバッテリ９１を用いた場合においても、バッテリ９１の長さの増大を抑えつつ、出力電圧を大きくすることができる。
なお、上述した実施形態では、無停電電源装置に用いられるバッテリを例にとって説明したが、無停電電源装置に限定されることなく、バッテリ付きの全ての電子機器に適用することができる。また、バッテリの種類や形状や容量は特に制限を設ける必要はなく、給電線の種類や形状は特に制限を設ける必要はない。 Accordingly, the length l of the power supply lines 93 and 94 can be determined without depending on the length of the battery 91, and the length l of the power supply lines 93 and 94 can be shortened. While it becomes possible to reduce the influence of radiation noise caused by standing waves generated on the electric wires 93 and 94, even when a single battery 91 is used, while suppressing an increase in the length of the battery 91, The output voltage can be increased.
In addition, although embodiment mentioned above demonstrated taking the battery used for an uninterruptible power supply as an example, it can apply to all the electronic devices with a battery, without being limited to an uninterruptible power supply. Further, the type, shape, and capacity of the battery need not be particularly limited, and the type and shape of the feeder line need not be particularly limited.
