Description

【0001】
【発明の属する技術分野】
この発明は、自動車用蓄電池の良否判定装置に関するものである。特に、移動が容易で、自動車やオートバイに搭載されて、その始動用、照明用ほかの電源として用いられる鉛蓄電池の状態の良否を、自動車に搭載した状態のまま安全、かつ簡便に判定することのできる装置に関するものである。
【0002】
【従来の技術】
これまで、鉛蓄電池の状態の良否を検出する方法としては、放電開始から一定時間後の放電電圧から劣化状態を推定するやり方が一般的であった。この方法は、鉛蓄電池の放電開始から一定時間後における放電電圧は、その鉛蓄電池の寿命や特性劣化状態と相関関係があることを利用したものである。鉛蓄電池は、使用につれて劣化が進み、電解液の減少や不働態化現象が高じると、内部抵抗および分極抵抗が増大して、起電力損失が増大する。これを利用して鉛蓄電池の状態の良否を判定する装置は多数提案されている。
【0003】
例えば、自動車に搭載された検査対象鉛蓄電池の正・負極端子に測定用ワニグチクリップをそれぞれ噛付かせ、検査装置内に設けた放電抵抗に短時間大電流を流し、その放電開始前後の電圧低下を解析して寿命判定を行うものが知られている(特許文献1参照)。この装置では、測定遅延回路と、定電圧ダイオードなどの電圧制限素子とを設けて計測主要部のアナログ−デジタル変換部への入力電圧を制限し、クリップ接続時の火花発生の防止や、計測時の大電流放電によって対象蓄電池自体を劣化させないような対策が講じられている。
【0004】
【特許文献1】
特開2001−15175号公報
【0005】
【発明が解決しようとする課題】
しかし、計測の実態は、検査装置を手持ち状態等で自動車に近づけ、装置から伸び出た短いケーブル先端のワニグチクリップを検査対象鉛蓄電池の正・負極端子に噛付かせるものである。このため、計測時の装置自体は傾斜を生じて不安定であり、自動車のフェンダー等を汚損したり、測定時の誤操作が原因で火花放電を発生したりするといった懸念があった。
【0006】
この発明の目的は、ガソリンスタンドや自動車用品店の店頭や敷地内に置いておき、使用時に移動させて自動車やオートバイに近づけ、安全、かつ簡便に自動車等に搭載したままの鉛蓄電池を点検して、その状態の良否を判定することのできる判定装置を提供することである。
【0007】
【課題を解決するための手段】
この発明の装置は、以下の構成からなるものである。
すなわち、移動の容易な台車と、台車に設置され、自動車に搭載された蓄電池を良否判定するための点検装置と、点検装置からの良否判定結果を印字出力するプリンタを主要部とし、点検装置は、同装置から導き出された2本のケーブルの先端に取り付けられ、自動車等に搭載された検査対象蓄電池の正・負極端子にそれぞれ噛付く2個の測定用端子と、検査対象蓄電池の容量サイズ、例えば19Ahとか24Ahとか、に応じて切替えるサイズ設定スイッチと、その蓄電池の検査直前の状態、例えば始動直後か長時間走行後か、に応じて切替えるモード設定スイッチと、測定用端子が正・負極端子に噛付いた蓄電池を試験放電するための測定開始スイッチと、試験放電結果からその蓄電池の状態、例えば良好、要充電、寿命末期、を判定する判定回路と、その判定結果をプリンタに送って印字出力する信号回路とを具備する。
【0008】
この発明のより好ましい自動車用蓄電池の良否判定装置は、カート型台車と、この台車の一部に安定良く設置された、蓄電池の良否を判定するための点検装置と、装置上方の台車引き手部分に取り付けられた点検装置取扱い説明書と、装置内に一体に、または別体に設けられ、装置からの良否判定結果を印字出力するプリンタを備え、点検装置は試験放電結果の演算処理を行う処理回路部分と、装置から導き出された2本のケーブルの先端にそれぞれ取り付けられ、自動車等に搭載されたままの検査対象蓄電池の正・負極端子にそれぞれ噛みつく2個の測定用ワニグチクリップと、対象蓄電池の容量サイズ、例えば19Ahとか24Ahとか、に応じて切替えるサイズ設定スイッチと、蓄電池の検査直前の状態、例えば始動直後か長時間走行後か、に応じて切替えるモード設定スイッチと、ワニグチクリップが正・負極端子にそれぞれ噛付いた対象蓄電池を試験放電するための測定開始スイッチと、前記の処理回路部分の一部を構成して、試験放電結果からその蓄電池の状態、例えば良好、要充電、寿命末期、を判定する判定回路と、判定結果をプリンタに送って印字出力する第1の信号回路と、ディスプレイに判定結果を送って良否の状態を表示させる第2の信号回路とを備えている。
【0009】
さらに、検査時の安全性をより高め、万一の蓄電池の破損、破裂からの防御対策として、2個の測定用ワニグチクリップのそれぞれには、このクリップが正・負極端子にそれぞれ噛付いた対象蓄電池の端子と液栓部を含む上部を覆う保護カバーが取りつけられている。
【0010】
【発明の実施の形態】
次に、この発明の好ましい実施形態を図面を参照して説明する。
図1は、この発明の判定装置を、自動車の始動用鉛蓄電池の正・負極端子に接続して良否判定する際の説明図である。図2は、カート型台車に点検装置を設置した判定装置全体の側面図であり、図3は同じくその判定装置全体を示した斜視図である。
【0011】
判定装置100は、下部に2個の車輪10aとスタンド脚10bを備えたカート型台車11と、その一部、ここでは下部の台座部15に安定良く設置された点検装置12と、この点検装置よりも上方の台車引き手部分13に取りつけられた装置の取扱い説明書14と、点検装置12からの判定結果を印字出力するプリンタを主要部として構成されている。
点検装置12には、その左右から引出し可能に長さ3〜4mの2本の測定用ケーブル16が設けられ、ケーブルの先端には検査対象蓄電池の正・負極端子に噛付く測定用ワニグチクリップ17が設けられている。装置内部には、いずれも周知の、蓄電池を放電させてその電圧降下を検出するための放電抵抗とリレー接点の直列回路及びその放電リレー制御部と、電圧検出回路と、基準電圧を得るための定電圧回路部と、電源をわずかな時間遅らせて定電圧回路部に供給する遅延回路部と、電圧検出回路からのデジタル信号を受け取って蓄電池の良否を判定する判定回路部とが設けられている。
【0012】
点検装置12の操作前面部には、図3で示すように、対象蓄電池の容量サイズ、例えば定格電圧12Vで、その電池容量が19Ahか、24Ah等かに応じて切替えるサイズ設定スイッチ18と、蓄電池の検査直前の状態、例えば始動直後か、長時間走行後か、に応じて切替えるモード設定スイッチ19と、放電抵抗に蓄電池を大電流放電させる測定開始スイッチ20が設置されている。
さらに、この装置と一体に判定回路部からの良否判定結果を印字出力するプリンタと、同じく良否判定結果を受け取って発光表示するディスプレイ22が設けられている。プリンタで印字された記録シートは、取出口21より排出される。
良否判定結果を印字出力するプリンタは、前記では点検装置に一体に設けているが、読み取りの容易さ、印字用紙の取り出しの簡易さを考慮して、点検装置の上方に点検装置とは別体で設けることもできる。
点検装置の左右にはケーブル収容ポケット23が設けられていて、使わない時点でのケーブル16をクリップ17ともども収めておくようになっている。
【0013】
この判定装置100は、自動車に搭載した検査対象の鉛蓄電池30をその状態に応じて良否判定するものである。
使用に当たっては、まずカート型台車11を引いて自動車の近くまで移動させ、起立状態に保つ。二番目に、取扱い説明書に記載された説明に従って、図1で示すように2本のケーブル16をポケット23から取り出して引き伸ばし、自動車に搭載された蓄電池30の正極端子31および負極端子32に、先端のクリップ17をその極性を確認してそれぞれ噛付かせる。三番目に、蓄電池の容量サイズに応じて設定を切替えるサイズ設定スイッチ18を操作し、四番目にその蓄電池の検査直前の状態が始動直後か、長時間走行後かを定めるモード設定スイッチ19を切替え操作して対象蓄電池に合致した試験条件を決定する。五番目に、測定開始スイッチ20を押す。
【0014】
前記の通り、2個のクリップ17間にはケーブルを経由して点検装置内の放電抵抗とリレーの接点との直列回路が接続されている。測定開始スイッチ20を押すことで、遅延回路の動作で約1秒程度の遅れをもってクリップ17を接続した正極端子からリレー接点経由で放電抵抗へ、そして負極端子へと短時間、例えば2〜3秒間100A程度の大電流が流れ、その際の電圧低下が電圧検出回路で検出される。装置内の判定回路ほかを動作させる定電圧回路は、先の遅延回路の動作遅れ以後供給される電源電圧で動作を開始して回路全般を正常に動作させる。電圧検出回路で検出された電圧低下はデジタル信号に変換され、これが演算処理部を持った判定回路部で基準値と比較解析され、その判定結果が出力される。判定結果の信号は、第1の信号回路を経由してこれを印字出力するプリンタに送られる。また、判定結果の信号の一部は第2の信号回路を経由して3個の発光ダイオード(LED)からなるディスプレイ22に送られ、該当する状態表示、例えば良好、要充電、および寿命末期にそれぞれ対応した緑色、黄色、および橙色のうちのいずれかを点灯させる。
【0015】
検査対象蓄電池30の良否を判定するに当たって、蓄電池の定格電圧や容量サイズおよび検査直前の状態によって判定基準、および判定結果は異なる。そこで装置に設けたサイズ設定スイッチ18は、定格電圧、例えば6V、12V、36V等の電圧つまみと、電池容量サイズ、例えば19Ah、24Ah等の容量つまみの2連つまみとしてもよい。また、検査直前の状態が始動直後か、長時間走行後かを定めるモード設定スイッチ19も切替え条件を細分化して切替え操作できるようにして、対象蓄電池に良く合致した試験条件を決定するとよい。
取扱い説明に従ったワニグチクリップ17の蓄電池端子への噛付かせと、試験条件決定後に、測定開始スイッチ20を押せば、試験放電とその判定結果がプリンタでの印字表示とディスプレイ22での発光表示との2通りで行われる。このため自動車使用者にとっては、検査した蓄電池の現在時点での良否の状態とその処置対策、例えばそのまま使用可か、回復充電を受けるか、今後の使用条件を勘案して蓄電池の取替えを行うかの判断を速やかに行うことができる。
【0016】
さらに、この蓄電池の良否判定装置は、ガソリンスタンドや自動車用品店の店頭や敷地内での使用が高く、従業員や他の自動車使用者の障害とならなく、安全を確保して使用することが望まれる。そのため、ケーブルはほぼその全長を引出してたるみやまき重ね状態をなくし、自動車に搭載の蓄電池位置を確認できる場所で操作することが好ましい。また、2個のワニグチクリップ17を蓄電池30の正・負極端子31、32に噛付かせた後、図4で示すようなクリップの取っ手部分に回ることができるように取りつけた、例えば透明なアクリル樹脂板からなる保護カバー33で端子と液栓部分を覆えば、誤接続や火花放電が万一起こった場合にも、電池の破裂等の影響が使用者に及ぶことを阻止できて安全性が高まる。
【0017】
【発明の効果】
以上説明したようにこの発明の良否判定装置は、容易に移動させることのできる台車に蓄電池の良否を判定する点検装置を設置しているので、台車を移動させて検査対象蓄電池を積んだままの自動車に近づき、先端に測定用端子を取り付けたケーブルを十分延ばして対象蓄電池の端子に測定用端子を噛付かせ、自動車とこの装置の両方の状態を確認しながら装置を操作して蓄電池の良否を安全かつ適切に知ることができる。しかも自動車とこの装置が適度に離れていて安全距離を確保できるので、万一誤接続や測定開始時に火花放電が生じても、蓄電池の破裂等で使用者に被害が及ぶことはなくできるという効果もある。

[0009]
Furthermore, as a measure to further increase the safety during inspection and to prevent damage and rupture of the storage battery, the two alligator clips for measurement should be attached to the positive and negative terminals of each clip. A protective cover is attached to cover the upper portion including the battery terminal and the liquid stopper.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, a preferred embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory diagram when the determination device of the present invention is connected to positive and negative terminals of a lead storage battery for starting an automobile to determine acceptability. FIG. 2 is a side view of the entire determination device in which an inspection device is installed on a cart-type cart, and FIG. 3 is a perspective view of the entire determination device.
[0011]
The determination device 100 includes a cart-type cart 11 having two wheels 10a and a stand leg 10b at a lower portion, an inspection device 12 stably installed on a part thereof, here, a lower pedestal portion 15, and an inspection device. A printer which prints out the instruction manual 14 of the device attached to the truck puller portion 13 above and the judgment result from the inspection device 12 is constituted as a main part.
The inspection device 12 is provided with two measurement cables 16 having a length of 3 to 4 m so as to be able to be pulled out from the left and right sides thereof, and a measurement crocodile clip 17 which is engaged with the positive and negative terminals of the storage battery to be inspected at the end of the cable. Is provided. Inside the device, a well-known series circuit of a discharge resistor and a relay contact for discharging a storage battery and detecting a voltage drop thereof and a discharge relay control unit thereof, a voltage detection circuit, and a reference voltage for obtaining a reference voltage. A constant voltage circuit section, a delay circuit section that supplies power to the constant voltage circuit section with a slight delay, and a determination circuit section that receives a digital signal from the voltage detection circuit and determines the quality of the storage battery is provided. .
[0012]
As shown in FIG. 3, a size setting switch 18 that switches according to the capacity size of the target storage battery, for example, a rated voltage of 12 V and the battery capacity is 19 Ah or 24 Ah, as shown in FIG. A mode setting switch 19 that switches according to the state immediately before the inspection, for example, immediately after starting or after running for a long time, and a measurement start switch 20 that discharges the storage battery with a large current to the discharge resistor are provided.
Further, a printer for printing out the pass / fail judgment result from the judgment circuit unit integrally with the apparatus and a display 22 for receiving the pass / fail judgment result and emitting and displaying the same are provided. The recording sheet printed by the printer is discharged from the outlet 21.
The printer that prints out the results of the pass / fail judgment is provided integrally with the inspection device in the above description. However, in consideration of the ease of reading and the easy removal of the printing paper, a printer separate from the inspection device is provided above the inspection device. Can also be provided.
Cable receiving pockets 23 are provided on the left and right sides of the inspection device, and the cable 16 is stored together with the clip 17 when not in use.
[0013]
The determination device 100 determines the acceptability of a lead storage battery 30 to be inspected mounted on an automobile according to its state.
In use, the cart-type cart 11 is first pulled and moved to the vicinity of the car, and is kept upright. Second, in accordance with the description in the instruction manual, the two cables 16 are taken out of the pocket 23 and stretched as shown in FIG. 1, and are connected to the positive terminal 31 and the negative terminal 32 of the storage battery 30 mounted on the automobile, After confirming the polarity, the clip 17 at the tip is engaged with each clip. Third, the size setting switch 18 for changing the setting according to the capacity size of the storage battery is operated. Fourth, the mode setting switch 19 for determining whether the state immediately before the inspection of the storage battery is immediately after starting or after long running is changed. Operate to determine test conditions that match the target storage battery. Fifth, the measurement start switch 20 is pressed.
[0014]
As described above, a series circuit of the discharge resistor in the inspection device and the contacts of the relay is connected between the two clips 17 via the cable. By pressing the measurement start switch 20, the operation of the delay circuit delays the operation of the delay circuit by about 1 second from the positive terminal connected to the clip 17 to the discharge resistor via the relay contact and then to the negative terminal for a short time, for example, 2 to 3 seconds. A large current of about 100 A flows, and a voltage drop at that time is detected by a voltage detection circuit. The constant voltage circuit that operates the decision circuit and the like in the apparatus starts operation with the power supply voltage supplied after the operation delay of the delay circuit, and normally operates the entire circuit. The voltage drop detected by the voltage detection circuit is converted into a digital signal, which is compared and analyzed with a reference value by a determination circuit unit having an arithmetic processing unit, and the determination result is output. The signal of the determination result is sent to a printer that prints out the signal via the first signal circuit. In addition, a part of the signal of the determination result is sent to the display 22 composed of three light emitting diodes (LEDs) via the second signal circuit, and the corresponding state display, for example, good, charge required, and end of life One of the corresponding green, yellow, and orange colors is turned on.
[0015]
In judging the quality of the storage battery 30 to be inspected, the criterion and the judgment result differ depending on the rated voltage and capacity size of the storage battery and the state immediately before the inspection. Therefore, the size setting switch 18 provided in the apparatus may be a dual knob of a voltage knob of a rated voltage, for example, 6 V, 12 V, 36 V, and a capacity knob of a battery capacity size, for example, 19 Ah, 24 Ah. Further, the mode setting switch 19 for determining whether the state immediately before the inspection is immediately after the start or after the running for a long period of time may be changed so that the switching condition can be subdivided and the switching operation can be performed to determine the test condition that is well matched to the target storage battery.
After the crocodile clip 17 is engaged with the storage battery terminal according to the handling instructions and the measurement start switch 20 is pressed after the test conditions are determined, the test discharge and the determination result are printed out on the printer and displayed on the display 22. It is performed in two ways. For this reason, for the vehicle user, whether the inspected storage battery is good or bad at the present time and a countermeasure for it, for example, whether the storage battery can be used as it is, undergoes recovery charging, or replaces the storage battery in consideration of future use conditions Can be promptly determined.
[0016]
Furthermore, this storage battery pass / fail determination device is frequently used in gas stations and in the stores of automobile supply stores and on premises, and can be used while ensuring safety without hindering employees or other car users. desired. Therefore, it is preferable to operate the cable at a place where the position of the storage battery mounted on the vehicle can be confirmed by eliminating the slack and overlapping state by pulling out almost the entire length of the cable. After the two alligator clips 17 are engaged with the positive / negative terminals 31 and 32 of the storage battery 30, they are attached so that they can be turned around the handle of the clip as shown in FIG. If the terminal and the liquid tap portion are covered with the protective cover 33 made of a resin plate, even if an erroneous connection or a spark discharge occurs, it is possible to prevent the effect of the battery from being ruptured and the like, thereby increasing the safety. .
[0017]
