電池(2次電池)の製造においては、作製した電池の充放電試験を行い、電池が所定の性能や特性を満たしているか否かを検査してから出荷している。このとき、電池の充放電試験は、その電池が実際に使用される環境下で行うことが重要である。そこで、電気自動車やハイブリッド自動車等の車両を駆動する電動機に電力を供給する車載用電池の充放電試験(耐久試験)を行う試験装置として、車両に搭載された車載用電池の使用時における充放電サイクルを再現して試験を行う車載用電池の充放電制御を行う充放電制御手段と、試験する車載用電池を収容して車載用電池の使用時における環境温度に保持する加熱機能を備えた第1の温度制御手段と、第1の温度制御手段内に冷風を送風して第1の温度制御手段内の温度を低下させる第2の温度制御手段と、第1の温度制御手段、第2の温度制御手段、及び充放電制御手段を制御し、環境条件や充放電条件を再現する制御装置とを備えた車載用電池の耐久試験装置(以下、単に電池試験装置という)が開示されている(例えば、特許文献1参照)。 In the manufacture of a battery (secondary battery), a charge / discharge test is performed on the manufactured battery, and it is shipped after checking whether the battery satisfies predetermined performance and characteristics. At this time, it is important to perform the charge / discharge test of the battery in an environment where the battery is actually used. Therefore, as a test device that performs a charge / discharge test (endurance test) for an in-vehicle battery that supplies electric power to an electric motor that drives a vehicle such as an electric vehicle or a hybrid vehicle, charging / discharging during use of the in-vehicle battery mounted on the vehicle Charge / discharge control means for controlling charging / discharging of an in-vehicle battery that performs a test by reproducing a cycle, and a heating function that accommodates the in-vehicle battery to be tested and maintains the ambient temperature at the time of use of the in-vehicle battery The first temperature control means, the second temperature control means for lowering the temperature in the first temperature control means by blowing cool air into the first temperature control means, the first temperature control means, the second temperature control means, An in-vehicle battery durability test apparatus (hereinafter simply referred to as a battery test apparatus) including a temperature control means and a control device that controls the charge / discharge control means and reproduces environmental conditions and charge / discharge conditions is disclosed (hereinafter simply referred to as a battery test apparatus). For example, patent text Reference 1).
特開2007−292654号公報JP 2007-292654 A
特許文献1に記載された形式の電池試験装置100では、図6(A)に示すように、例えば、第1の温度制御手段、第2の温度制御手段、及び制御装置の一部を一体化して恒温槽101とし、充放電制御手段及び制御装置の残部を一体化して充放電試験器102とし、恒温槽101と充放電試験器102を接続ケーブル103を介して連結している。ここで、符号104は恒温槽101と充放電試験器102の運転管理、充放電試験器102で得られた試験結果を収録して解析を行うパーソナルコンピュータを支持するPCラック、符号105、106は充放電試験器102の各機器の操作やメンテナンスを行う際に使用する充放電試験器102の開閉扉、符号107は車載用電池の出し入れに使用する恒温槽101の開閉扉である。符号108は恒温槽101、充放電試験器102及びコンピュータの電源ケーブル(図示せず)、接続ケーブル103等の各種ケーブルを支持する配線ラックである。 In the battery test apparatus 100 of the type described in Patent Document 1, as shown in FIG. 6A, for example, the first temperature control means, the second temperature control means, and a part of the control apparatus are integrated. The constant temperature bath 101 is formed, and the charge / discharge control means and the rest of the control device are integrated to form a charge / discharge tester 102, and the constant temperature bath 101 and the charge / discharge tester 102 are connected via a connection cable 103. Here, reference numeral 104 denotes a PC rack that supports a personal computer that performs operation management of the thermostatic chamber 101 and the charge / discharge tester 102, and records and analyzes the test results obtained by the charge / discharge tester 102. Reference numerals 105 and 106 denote The open / close door of the charge / discharge tester 102 used when operating and maintaining each device of the charge / discharge tester 102, and 107 is the open / close door of the thermostatic chamber 101 used for loading / unloading the vehicle-mounted battery. Reference numeral 108 denotes a wiring rack that supports various cables such as the thermostatic chamber 101, the charge / discharge tester 102, a computer power cable (not shown), and the connection cable 103.
従って、1台の電池試験装置100を設置する場合、恒温槽101、充放電試験器102及びPCラック104の設置場所をそれぞれ確保しなければならず、電池試験装置100を複数同時に使用する場合、複数の電池試験装置100を並べて設置する場所の確保が非常に困難になるという問題がある
また、電池試験装置100を客先に納入する場合、電池試験装置100を製作した工場での出荷前検査試験を行った後、恒温槽101と充放電試験器102を繋いでいる接続ケーブル103を取り外して恒温槽101、充放電試験器102及び接続ケーブル103に分解しそれぞれ梱包して客先納入場所に搬送し、客先納入場所(現地)で電池試験装置100に復元して電池試験装置100の現地試運転を行うという一連の作業が必要になる。このため、電池試験装置100の工場出荷及び試運転に伴う付帯作業に要する時間が長くなるという問題がある。
Therefore, when installing one battery test apparatus 100, it is necessary to secure the installation locations of the constant temperature bath 101, the charge / discharge tester 102, and the PC rack 104, and when using a plurality of battery test apparatuses 100 simultaneously, There is a problem that it is very difficult to secure a place where a plurality of battery test apparatuses 100 are installed side by side. Also, when the battery test apparatus 100 is delivered to a customer, an inspection before shipment at the factory where the battery test apparatus 100 is manufactured. After performing the test, the connection cable 103 connecting the thermostat 101 and the charge / discharge tester 102 is removed, and the thermostat 101, the charge / discharge tester 102 and the connection cable 103 are disassembled and packed, respectively, and packed at the customer delivery location. It is necessary to carry out a series of operations such as transporting, restoring the battery test apparatus 100 at the customer delivery location (local), and performing on-site test operation of the battery test apparatus 100. For this reason, there exists a problem that the time which the incidental work accompanying the factory shipment of the battery test apparatus 100 and a test run requires becomes long.
更に、恒温槽101と充放電試験器102を接続ケーブル103で接続する場合、恒温槽101と充放電試験器102にそれぞれ接続ケーブル103を固定する端子台を設ける必要がある。このため、恒温槽101と充放電試験器102の部品数が増加し、恒温槽101と充放電試験器102のそれぞれの製作コストが上昇するという問題が生じる。また、据付け場所の制約により、恒温槽101と充放電試験器102の距離が大きくなって接続ケーブル103の長さが長くなると、充放電試験時に接続ケーブル103内で電圧降下が生じる。そして、予想される電圧降下が無視できない場合、電圧降下を抑制するために接続ケーブル103の線径を太くしなければならない。このため、接続ケーブル103のコストが上昇すると共に、接続ケーブル103の重量が重くなり、配線作業の負担が増加すると共に、配線ラック108の強度向上を図るため配線ラック108の製作コストが上昇するという問題が生じる。 Furthermore, when connecting the constant temperature bath 101 and the charge / discharge tester 102 with the connection cable 103, it is necessary to provide a terminal block for fixing the connection cable 103 to the constant temperature bath 101 and the charge / discharge tester 102. For this reason, the number of parts of the thermostat 101 and the charge / discharge tester 102 increases, and there arises a problem that the production costs of the thermostat 101 and the charge / discharge tester 102 increase. Further, if the distance between the thermostatic chamber 101 and the charge / discharge tester 102 is increased due to restrictions on the installation location and the length of the connection cable 103 is increased, a voltage drop occurs in the connection cable 103 during the charge / discharge test. If the expected voltage drop cannot be ignored, the diameter of the connection cable 103 must be increased in order to suppress the voltage drop. This increases the cost of the connection cable 103, increases the weight of the connection cable 103, increases the burden of wiring work, and increases the manufacturing cost of the wiring rack 108 to improve the strength of the wiring rack 108. Problems arise.
本発明はかかる事情に鑑みてなされたもので、恒温槽と充放電試験器を一体化して、サイズの小型化、充放電試験時の電圧降下の防止、及び製作コストの低減を図った電池の充放電試験装置を提供することを目的とする。 The present invention has been made in view of such circumstances, and is a battery that integrates a thermostatic chamber and a charge / discharge tester to reduce the size, prevent the voltage drop during the charge / discharge test, and reduce the production cost. An object is to provide a charge / discharge test apparatus.

A constant temperature bath provided with, a charge / discharge tester for conducting a charge / discharge test by energizing each of the batteries in the thermostat, a control means for setting and adjusting the test temperature, the heating / cooling means, In a battery charge / discharge test apparatus having a thermostat, a cradle (for example, a housing) for housing the charge / discharge tester and the control means,
The thermostatic chamber is disposed on the front upper side of the gantry with the open / close door exposed on the front surface of the gantry, the heating and cooling means is disposed on the lower side of the gantry, and the charge / discharge tester is Arranged on one side in the left-right direction on the back side of the gantry, the control means is located on one side in the left-right direction on the front side of the gantry with the operation part of the control means positioned on one side in the left-right direction of the door And
On the other side in the left-right direction on the back side of the gantry, an exhaust path is provided for discharging the cooling air after cooling the heating and cooling means to the outside of the gantry.
本発明に係る電池の充放電試験装置において、前記架台の前面下部には前記冷却用空気の取り込み口が設けられていることが好ましい。 In the battery charge / discharge test apparatus according to the present invention, it is preferable that the cooling air intake port is provided in a lower front portion of the frame.
本発明に係る電池の充放電試験装置において、前記恒温槽の下方には露受パンが設けられ、該露受パンには前記架台の背面の一側下部に設けられた排水管接続口に連通する排水口が形成されていることが好ましい。 In the battery charge / discharge test apparatus according to the present invention, a dew pan is provided below the thermostatic bath, and the dew pan is communicated with a drain pipe connection port provided at a lower portion on one side of the back of the gantry. It is preferable that a drain outlet is formed.
本発明に係る電池の充放電試験装置においては、恒温槽、加熱冷却手段、充放電試験器、及び制御手段の相互位置関係を考慮して架台内に収容して一体化したので、架台をコンパクトにすることができ、電池の充放電試験装置の設置面積を縮小することができる。
そして、架台の背面側の左右方向他側に、加熱冷却手段を冷却した後の冷却用空気を架台の外部に放出する排気路を設けたので、充放電試験器の他側が排気路側に位置することになって、排気路を通過する使用済の冷却用空気の流れによって、充放電試験器内からの熱を効率的に排出することができる。
また、恒温槽、加熱冷却手段、充放電試験器、及び制御手段が一体化しているので、従来のように、電池の充放電試験装置を出荷時に各機器に分解して梱包する作業、納入場所における電池の充放電試験装置の復元作業を省くことができ、電池の充放電試験装置を迅速に出荷することができると共に、納入場所における試運転を迅速に行うことができる。
更に、従来のように、恒温槽と充放電試験器にそれぞれ接続ケーブル用の端子台を設ける必要がないため、装置の製作コストを低減することができる。
In the battery charge / discharge test apparatus according to the present invention, since the thermostat, the heating / cooling means, the charge / discharge tester, and the control means are taken into consideration and integrated in the gantry, the gantry is compact. The installation area of the battery charge / discharge test apparatus can be reduced.
And since the exhaust passage which discharges the cooling air after cooling the heating and cooling means to the outside of the gantry is provided on the other side in the left and right direction on the back side of the gantry, the other side of the charge / discharge tester is located on the exhaust channel side As a result, the heat from the charge / discharge tester can be efficiently discharged by the flow of the used cooling air passing through the exhaust passage.
In addition, the constant temperature bath, heating / cooling means, charge / discharge tester, and control means are integrated. Thus, the battery charge / discharge test apparatus can be quickly restored, and the test operation at the delivery location can be performed quickly.
Furthermore, since it is not necessary to provide a terminal block for the connection cable in each of the thermostatic chamber and the charge / discharge tester as in the prior art, the manufacturing cost of the device can be reduced.
そして、恒温槽の左右方向一側の側部にケーブル孔を設けると、架台内に恒温槽内の電池の電極と充放電試験器を連結する接続ケーブルを配設することができ、接続ケーブルの長さを短くすることができる。その結果、充放電試験時に接続ケーブル内で顕著な電圧降下が生じることを防止できる。これにより、接続ケーブルの線径を太くする必要がなくなり、接続ケーブルのコスト上昇の防止、軽量化が可能になる。また、従来のように接続ケーブルを配線ラック内に配線する必要がないため、配線作業の負担を軽減することができ、配線ラックの強度向上を図る必要もないため、配線ラックの製作コストの軽減も可能になる。なお、ケーブル孔を挿通する接続ケーブルとケーブル孔の内周との間にはシール材を充填して、恒温槽内と外部との間でケーブル孔を介した熱の出入を抑制するようにすることが好ましい。 And if a cable hole is provided in the side of the one side in the left-right direction of the thermostat, a connection cable for connecting the electrode of the battery in the thermostat and the charge / discharge tester can be arranged in the gantry. The length can be shortened. As a result, it is possible to prevent a significant voltage drop from occurring in the connection cable during the charge / discharge test. This eliminates the need to increase the diameter of the connection cable, thereby preventing an increase in the cost of the connection cable and reducing the weight. In addition, since it is not necessary to wire the connection cable in the wiring rack as in the past, it is possible to reduce the burden of wiring work, and it is not necessary to improve the strength of the wiring rack, thus reducing the manufacturing cost of the wiring rack. Is also possible. It should be noted that a sealing material is filled between the connection cable inserted through the cable hole and the inner periphery of the cable hole so as to suppress heat input and output through the cable hole between the inside of the thermostatic bath and the outside. It is preferable.
本発明に係る電池の充放電試験装置において、架台の前面下部に冷却用空気の取り込み口が設けられている場合、架台内に架台の前面下部から背面側の排気路下部に向かう冷却用空気の流れを形成することができ、加熱冷却手段の冷却を効率的に行うことができる。 In the battery charge / discharge test apparatus according to the present invention, when the cooling air intake port is provided in the lower front portion of the gantry, the cooling air flowing from the lower front surface of the gantry to the lower exhaust passage on the rear side is installed in the gantry. A flow can be formed, and the heating and cooling means can be efficiently cooled.

恒温槽本体31aに対して別体で設けられる加熱冷却手段11は、図4に示すように、例えば圧縮機39と凝縮器40を備えたヒートポンプである。圧縮機39で圧縮した冷媒(例えば、R404A)を凝縮器40で気体状態から液体状態に変化させ、このとき冷媒から放出される熱で図示しない熱交換部を加熱して温風を形成し、得られた温風は図示しない吹込み管を介して試験室31の上部から内部に供給することにより試験室31内の温度を上昇させる。なお、試験室31内に吹込まれた温風は試験室31の下部から図示しない排出管を介して熱交換部に戻され、再び加熱されて試験室31内に供給される。また、圧縮機39で圧縮した冷媒を断熱膨張させて液体状態とし、液体状態の冷媒が気体状態に変わる際に吸収する熱により熱交換部を冷却して冷風を形成し、得られた冷風を吹込み管を介して試験室31の上部から内部に供給することにより試験室31内の温度を低下させる。なお、試験室31内に吹込まれた冷風は試験室31の下部から排出管を介して熱交換部に戻され、再び冷却されて試験室31内に供給される。これによって、試験室31内の温度を、例えば、−40〜100℃の範囲に設定することができる。 As shown in FIG. 4, the heating / cooling means 11 provided separately from the thermostat body 31 a is a heat pump including a compressor 39 and a condenser 40, for example. The refrigerant (for example, R404A) compressed by the compressor 39 is changed from a gas state to a liquid state by the condenser 40, and at this time, a heat exchange unit (not shown) is heated by heat released from the refrigerant to form hot air, The obtained hot air is supplied from the upper part of the test chamber 31 through a blow pipe (not shown) to raise the temperature in the test chamber 31. The hot air blown into the test chamber 31 is returned from the lower portion of the test chamber 31 to the heat exchanging section through a discharge pipe (not shown), heated again, and supplied into the test chamber 31. In addition, the refrigerant compressed by the compressor 39 is adiabatically expanded into a liquid state, the heat exchange part is cooled by heat absorbed when the liquid state refrigerant changes to a gaseous state, and cold air is formed. The temperature in the test chamber 31 is lowered by supplying the inside from the upper part of the test chamber 31 through the blowing tube. The cold air blown into the test chamber 31 is returned from the lower portion of the test chamber 31 to the heat exchange section through the discharge pipe, cooled again, and supplied into the test chamber 31. Thereby, the temperature in the test chamber 31 can be set in a range of, for example, −40 to 100 ° C.
熱媒が液体状態から気体状態に変化する際に吸収した熱は、凝縮器40から外部に放出される。ここで、図4に示すように、凝縮器40の背面側には排気ファン41が設けられ、排気ファン41の下流側は排気路18の下部と連通している。このため、排気ファン41を運転して架台16の前面下部の取り込み口29から取り入れた冷却用空気を凝縮器40に供給することにより、取り込み口29から取り込まれ凝縮器40を経て排気路18に流入する冷却用空気の流れを形成することができ、凝縮器24からの放熱を促進することができる。 The heat absorbed when the heat medium changes from the liquid state to the gas state is released from the condenser 40 to the outside. Here, as shown in FIG. 4, an exhaust fan 41 is provided on the back side of the condenser 40, and the downstream side of the exhaust fan 41 communicates with the lower portion of the exhaust path 18. For this reason, by operating the exhaust fan 41 and supplying the cooling air taken in from the intake port 29 at the lower front of the gantry 16 to the condenser 40, the air is taken in from the intake port 29 and passes through the condenser 40 to the exhaust path 18. A flow of cooling air that flows in can be formed, and heat dissipation from the condenser 24 can be promoted.
図1に示すように、試験室31の下方には、露受パン42が設けられている。そして、露受パン42には、図5に示すように、架台16の裏カバー部材23の右側の下部に設けられた排水管接続口43と図示しない配管を介して連通する排水口(図示せず)が形成されている。このような構成とすることにより、試験室31内の温度を氷点下に保持した際に、試験室31の外周部で結露した結露水を回収して架台16の外部に排水することができる。 As shown in FIG. 1, a dew pan 42 is provided below the test chamber 31. As shown in FIG. 5, the dew pan 42 is connected to a drain pipe connection port 43 provided at the lower right side of the back cover member 23 of the gantry 16 via a pipe (not shown). ) Is formed. With such a configuration, when the temperature in the test chamber 31 is kept below freezing, the dew condensation water condensed on the outer periphery of the test chamber 31 can be collected and drained outside the gantry 16.
充放電試験器14は、電池に通電して電池の充電を行う電源部と、充放電時の電圧及び電流を計測する計測部と、電池から放電された電流を回収する回生部とを備えた電源試験ユニット44を複数(即ち、試験を行う電池の個数に相当する数)有している。ここで、電源試験ユニット44は、枠体19の背面側の右側に上下方向に複数段に設けられたラック45に載置されている。これにより、排気路18の右側(一側)に、電源試験ユニット44の他側(背面側)を上下方向に並べて配置することができ、電源試験ユニット44の背面側に設けられた排気ファン46により、電源試験ユニット44内で発生した熱を排気路18に放出することができる。 The charge / discharge tester 14 includes a power supply unit that energizes the battery to charge the battery, a measurement unit that measures voltage and current during charge / discharge, and a regenerative unit that collects the current discharged from the battery. A plurality of power supply test units 44 (that is, the number corresponding to the number of batteries to be tested) are provided.

It is possible to prevent a significant voltage drop in the connection cable 47 during the charge / discharge test. In addition, since the sealing material 49 is filled between the connection cable 47 inserted through the cable hole 48 and the inner periphery of the cable hole 48, heat is transferred between the inside of the test chamber 31 and the outside via the cable hole 48. The movement can be suppressed, and the temperature in the test chamber 31 can be easily adjusted.

The installation area of the apparatus 10 is reduced. As a result, when a plurality of charge / discharge test apparatuses 10 are used side by side, the floor area required for installation can be greatly reduced as compared with an apparatus having a conventional configuration.
