Description

【０００１】
【発明の属する技術分野】
本発明は、蓄電池放電試験システムに関し、特に、通信用のバックアップシステム等においてニッケル水素電池等の蓄電池の放電試験を行うための蓄電池放電試験システムに関するものである。
【０００２】
【従来の技術】
蓄電池は時間とともに次第に劣化していくが、通信用のバックアップシステムでは蓄電池は常に満充電に近い状態で維持されており、サイクル的な使用の場合と違って使用時に放電容量の低下を認識するのは難しい。したがって、定期的に放電試験を行い、所望の放電容量を満足しているか否かの試験を行っている。また、ニッケル水素電池等は自己放電とそれを補うための補充電といった浅い充放電の繰り返しによりメモリ効果を引き起こすおそれもあるため定期的な放電試験は重要である。
【０００３】
従来の蓄電池放電試験システムを図２に示す。図中、１は蓄電池、２は電圧調整コンバータ、３は整流器、４は負荷、５はスイッチ、６ｂは放電試験用コンバータ、８は放電試験用負荷である。
【０００４】
通常、整流器３は商用電源に接続し、整流器３が商用電源からの電力（交流）を整流して出力する直流電力が負荷４に供給され、蓄電池１からは電力供給されていないが、整流器３からの出力が途絶えたり、その出力電圧が負荷４の許容入力電圧範囲外にまで低下した場合に備えて、その場合に蓄電池１から負荷４に電力供給できるように、蓄電池１の電圧を負荷４の許容入力電圧範囲内に電圧調整する電圧調整コンバータ２が蓄電池１と負荷４との間に設けられている。
【０００５】
蓄電池１の放電試験を行うときには、スイッチ５を投入し、放電試験コンバータ６ｂにより放電試験用負荷８に一定の電流が供給され、たとば０.１ＣＡの放電レートで蓄電池１の定電流放電試験を行うことができる。すなわち、たとえば０.１ＣＡの放電レートに対応する一定放電電流値Ｉ０．１で蓄電池１が放電を続け、蓄電池１の電池電圧が許容される最低電圧値になるまでの時間がｔｄｉｓであったとすると、蓄電池１の放電容量はＩ０．１・ｔｄｉｓ（Ｉ０．１とｔｄｉｓとの積）として求められる。蓄電池１が所望の放電容量を維持しているか否かの判定は、このようにして求められた放電容量に基づいて行われる。
【０００６】
この放電試験を行っているときには、電圧調整コンバータ２の出力電圧は整流器３の出力電圧よりも低く設定されているため、負荷４には整流器３のみから電力が供給される。
【０００７】
万一、放電試験中に整流器３からの出力が途絶えたり、その出力電圧が負荷４の許容入力電圧範囲外にまで低下した場合にはスイッチ５をオフし、蓄電池１から電圧調整コンバータ２を介して負荷に電力供給することができる。
【０００８】
【発明が解決しようとする課題】
しかしながら、従来の蓄電池放電試験システムでは、放電試験用負荷を用いるため装置サイズやコストの増大が問題であった。また、蓄電池に蓄積された電力が放電試験用負荷により無駄に消費されるという問題があった。
【０００９】
本発明は、このような問題を解決するためになされたものであり、本発明の目的は、放電試験用負荷を必要としない小型で高効率な蓄電池放電試験システムを提供することにある。
【００１０】
【課題を解決するための手段】
上記課題を解決するために、本発明においては、請求項１に記載のように、
入力端は蓄電池の出力端にスイッチを介して接続され、出力端は整流器から負荷への電力供給ラインに並列に接続され、該スイッチが閉じられたときに該スイッチを介して流れる入力電流である該蓄電池の放電電流があらかじめ定められた一定値となるように制御しながら該電力供給ラインに電力を出力する放電試験用コンバータを備えることを特徴とする蓄電池放電試験システムを構成する。
【００１１】
【課題を解決するための手段】
上記課題を解決するために、本発明においては、請求項１に記載のように、
入力端は蓄電池の出力端にスイッチを介して接続され、出力端は整流器から負荷への電力供給ラインに並列に接続され、該スイッチが閉じられたときに該スイッチを介して流れる入力電流である該蓄電池の放電電流があらかじめ定められた一定値となるように制御しながら該電力供給ラインに電力を出力する放電試験用コンバータと、前記整流器とを構成要素とする蓄電池放電試験システムであって、該スイッチが閉じられ、前記放電試験用コンバータが前記負荷へ電力を供給する際に、前記負荷が必要とする電力の不足分を前記整流器が前記負荷へ供給することを特徴とする蓄電池放電試験システムを構成する。
また、本発明においては、請求項２に記載のように、
前記一定値は、前記負荷が消費する電流が最も小さい場合でも、前記整流器からの供給電流が零にならない値に設定されることを特徴とする請求項１に記載の蓄電池放電試験システムを構成する。
【００１２】
図１は、本発明の実施形態例の蓄電池放電試験システムの構成を示すブロック図である。図中、前記従来例と同一箇所には同一の符号を付し、重複説明を省略する。図中、６ａは放電試験用コンバータであり、７は負荷４への電力供給ラインである。
【００１３】
放電試験用コンバータ６ａの入力端は蓄電池１の出力端にスイッチ５を介して接続され、放電試験用コンバータ６ａの出力端は電力供給ライン７に並列に接続されている。
【００１４】
通常、整流器３は商用電源に接続し、整流器３が商用電源からの電力（交流）を整流して出力する直流電力が、電力供給ライン７を通じて、負荷４に供給され、蓄電池１からは電力供給されていないが、整流器３からの出力が途絶えたり、その出力電圧が負荷４の許容入力電圧範囲外にまで低下した場合に備えて、その場合に蓄電池１から負荷４に電力供給できるように、蓄電池１の電圧を負荷４の許容入力電圧範囲内に電圧調整する電圧調整コンバータ２が蓄電池１と負荷４との間に設けられている。
【００１５】
本発明の実施形態例の蓄電池放電試験システムの動作を、図１を参照しながら以下に説明する。
【００１６】
蓄電池１の放電試験を行うときには、スイッチ５を投入する。放電試験用コンバータ６ａは、蓄電池１からの入力電流Ｉが一定値となるように出力を制御しながら、電力供給ライン７を通じて、負荷４へ電力供給する。負荷４には、放電試験用コンバータ６ａからの電力が供給されるとともに、不足分の電力が整流器３から供給される。放電試験用コンバータ６ａから整流器３への電力の逆流を防ぐために、負荷４の消費する電流が最も小さい場合でも整流器３からの供給電流が零にならないように、蓄電池１から放電試験用コンバータ６ａへの入力電流Ｉを設定する必要がある。通常、通信用の負荷は通信量に応じて多少の負荷変動があるものの、通信が全くない場合でも、ある程度の負荷電力を消費するので、上記のように蓄電池１からの入力電流Ｉを設定することは可能である。このような一定放電電流値Ｉで蓄電池１が放電を続け、蓄電池１の電池電圧が許容される最低電圧値になるまでの時間がｔｄｉｓであったとすると、蓄電池１の放電容量はＩ・ｔｄｉｓ（Ｉとｔｄｉｓとの積）として求められる。蓄電池１が所望の放電容量を維持しているか否かの判定は、このようにして求められた放電容量に基づいて行われる。
【００１７】
以上述べたように、本実施の形態例によれば、蓄電池１の定電流放電試験を行いつつ、蓄電池１に蓄積された電力を負荷４に供給することができる。このように、本発明においては、従来技術と異なり、放電試験専用の負荷が不要となり、このような負荷による装置サイズ及びコストの増大や無駄な電力の消費をなくすことができる。
【００１８】
【発明の効果】
本発明の実施により、放電試験用負荷を必要としない小型で高効率な蓄電池放電試験システムを提供することが可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a storage battery discharge test system, and more particularly to a storage battery discharge test system for performing a discharge test of a storage battery such as a nickel metal hydride battery in a communication backup system or the like.
[0002]
[Prior art]
The storage battery gradually deteriorates with time, but in the backup system for communication, the storage battery is always kept near full charge, and unlike the case of cyclic use, it recognizes a decrease in discharge capacity at the time of use. Is difficult. Therefore, a discharge test is periodically performed to test whether or not a desired discharge capacity is satisfied. In addition, since a nickel-metal hydride battery or the like may cause a memory effect due to repeated shallow charge and discharge such as self-discharge and supplementary charge for compensating for it, a periodic discharge test is important.
[0003]
A conventional storage battery discharge test system is shown in FIG. In the figure, 1 is a storage battery, 2 is a voltage regulator converter, 3 is a rectifier, 4 is a load, 5 is a switch, 6b is a converter for discharge test, and 8 is a load for discharge test.
[0004]
Usually, the rectifier 3 is connected to a commercial power source, and the rectifier 3 rectifies and outputs the electric power (alternating current) from the commercial power source and is supplied to the load 4. The rectifier 3 is not supplied with power from the storage battery 1. In this case, the voltage of the storage battery 1 is supplied to the load 4 so that power can be supplied from the storage battery 1 to the load 4 in case the output from the battery stops or the output voltage falls outside the allowable input voltage range of the load 4. A voltage adjustment converter 2 that adjusts the voltage within the allowable input voltage range is provided between the storage battery 1 and the load 4.
[0005]
When the discharge test of the storage battery 1 is performed, the switch 5 is turned on, and a constant current is supplied to the discharge test load 8 by the discharge test converter 6b. For example, the constant current discharge test of the storage battery 1 is performed at a discharge rate of 0.1 CA. It can be carried out. Thus, for example battery 1 continues to discharge at a constant discharge current value I 0.1 corresponding to the discharge rate of 0.1 CA, the time until the minimum voltage value of the battery voltage of the battery 1 is allowed t dis met If this is the case, the discharge capacity of the storage battery 1 is obtained as I 0.1 · t dis (product of I 0.1 and t dis ). Whether or not the storage battery 1 maintains a desired discharge capacity is determined based on the discharge capacity thus obtained.
[0006]
During this discharge test, the output voltage of the voltage regulating converter 2 is set lower than the output voltage of the rectifier 3, so that the load 4 is supplied with power only from the rectifier 3.
[0007]
In the unlikely event that the output from the rectifier 3 is interrupted during the discharge test, or the output voltage falls outside the allowable input voltage range of the load 4, the switch 5 is turned off and the storage battery 1 through the voltage regulator converter 2 is turned off. Power to the load.
[0008]
[Problems to be solved by the invention]
However, in the conventional storage battery discharge test system, since the load for discharge test is used, the increase in apparatus size and cost has been a problem. In addition, there is a problem that the electric power stored in the storage battery is wasted by the discharge test load.
[0009]
The present invention has been made to solve such a problem, and an object of the present invention is to provide a small and highly efficient storage battery discharge test system that does not require a discharge test load.
[0010]
[Means for Solving the Problems]
In order to solve the above problems, in the present invention, as described in claim 1,
The input terminal is connected to the output terminal of the storage battery via a switch, the output terminal is connected in parallel to the power supply line from the rectifier to the load, and is an input current that flows through the switch when the switch is closed. A storage battery discharge test system is provided that includes a discharge test converter that outputs power to the power supply line while controlling the discharge current of the storage battery to be a predetermined constant value.
[0011]
[Means for Solving the Problems]
In order to solve the above problems, in the present invention, as described in claim 1,
The input terminal is connected to the output terminal of the storage battery via a switch, the output terminal is connected in parallel to the power supply line from the rectifier to the load, and is an input current that flows through the switch when the switch is closed. A storage battery discharge test system comprising a discharge test converter that outputs power to the power supply line while controlling the discharge current of the storage battery to be a predetermined constant value, and the rectifier, When the switch is closed and the discharge test converter supplies power to the load, the rectifier supplies a shortage of power required by the load to the load. Configure.
In the present invention, as described in claim 2,
2. The storage battery discharge test system according to claim 1, wherein the constant value is set to a value at which a supply current from the rectifier does not become zero even when the current consumed by the load is the smallest. .
[0012]
FIG. 1 is a block diagram showing a configuration of a storage battery discharge test system according to an embodiment of the present invention. In the figure, the same parts as those in the conventional example are denoted by the same reference numerals, and redundant description is omitted. In the figure, reference numeral 6a denotes a discharge test converter, and reference numeral 7 denotes a power supply line to the load 4.
[0013]
The input end of the discharge test converter 6 a is connected to the output end of the storage battery 1 via the switch 5, and the output end of the discharge test converter 6 a is connected in parallel to the power supply line 7.
[0014]
Usually, the rectifier 3 is connected to a commercial power supply, and the DC power output by the rectifier 3 rectifying and outputting the power (AC) from the commercial power supply is supplied to the load 4 through the power supply line 7 and supplied from the storage battery 1. In order to be able to supply power from the storage battery 1 to the load 4 in that case, the output from the rectifier 3 is interrupted or the output voltage falls outside the allowable input voltage range of the load 4. A voltage adjustment converter 2 that adjusts the voltage of the storage battery 1 within the allowable input voltage range of the load 4 is provided between the storage battery 1 and the load 4.
[0015]
The operation of the storage battery discharge test system according to the embodiment of the present invention will be described below with reference to FIG.
[0016]
When performing a discharge test of the storage battery 1, the switch 5 is turned on. The discharge test converter 6a supplies power to the load 4 through the power supply line 7 while controlling the output so that the input current I from the storage battery 1 becomes a constant value. The load 4 is supplied with power from the discharge test converter 6 a and is supplied with insufficient power from the rectifier 3. In order to prevent the backflow of power from the discharge test converter 6a to the rectifier 3, even when the current consumed by the load 4 is the smallest, the supply current from the rectifier 3 does not become zero, so that the storage battery 1 is discharged to the discharge test converter 6a. Needs to be set. Normally, the communication load has some load fluctuation depending on the amount of communication, but even when there is no communication, a certain amount of load power is consumed, so the input current I from the storage battery 1 is set as described above. It is possible. If the storage battery 1 continues to discharge at such a constant discharge current value I and the time until the battery voltage of the storage battery 1 reaches the lowest allowable voltage value is tdis , the discharge capacity of the storage battery 1 is I · t calculated as dis (product of I and tdis ). Whether or not the storage battery 1 maintains a desired discharge capacity is determined based on the discharge capacity thus obtained.
[0017]
As described above, according to the present embodiment, the power stored in the storage battery 1 can be supplied to the load 4 while performing the constant current discharge test of the storage battery 1. Thus, in the present invention, unlike the prior art, a load dedicated to a discharge test is not required, and an increase in device size and cost and unnecessary power consumption due to such a load can be eliminated.
[0018]
【The invention's effect】
By carrying out the present invention, it is possible to provide a small and highly efficient storage battery discharge test system that does not require a discharge test load.
