JP 2007-292654 A

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.

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.

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.

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.

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.

By providing the cable hole 48 in the right side wall portion of the test chamber 31 based on the positional relationship between the test chamber 31 and the power supply test unit 44, the length of the connection cable 47 connecting the battery and the power supply test unit 44 can be shortened. 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. Then, the confirmation of the sealing state by the sealing material 49 and the maintenance of the sealing state can be performed by removing the second right cover member 22a from the frame body 19 and exposing the sealing material 49.
Reference numeral 51 denotes a cooling air intake hole for the power supply test unit 44 formed in the third right cover member 22b.

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.
Reference numeral 56 denotes a personal computer that records and analyzes the operation management of the charge / discharge test apparatus 10 and the test results obtained by the charge / discharge tester 14.

In addition, since the constant temperature bath 13, the heating / cooling means 11, the charge / discharge tester 14, and the control means 15 are integrated, the work of disassembling and packing each device at the time of shipment of the charge / discharge test apparatus 10 as in the prior art. Thus, the work of restoring the charge / discharge test apparatus 10 at the delivery location can be omitted, the charge / discharge test apparatus 10 can be shipped quickly, and the test run 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 13 and the charge / discharge tester 14 as in the prior art, the manufacturing cost can be reduced.
