Embodiment Construction

[0014] Such as figure 1 Shown is a schematic diagram of the operating environment of a preferred embodiment of the battery charging and discharging reliability testing system of the present invention. The battery charging and discharging reliability test system 10 runs in the main control computer 1 . The master computer 1 is connected to a power supply 3 through a power supply control channel 2, and is connected to an electrical signal tester 5 through an electrical signal tester control channel 4. The main control computer 1 controls the power supply 3 to charge and discharge the battery 6 through the battery charging and discharging reliability testing system 10, and measures the voltage and current of the charged and discharged battery 6 through the electrical signal tester 5, and The measured voltage and current values ​​are stored in a lifetime curve database 11 . From the measured voltage value and current value, the reliability of charging and discharging of the batt...

Abstract

The invention relates to a method for testing the charge-discharge reliability of a battery, which comprises the following steps: controlling a power supply to charge the battery; when the charging is finished, notifying an electrical signal tester to repeatedly measure the voltage and the current of the battery; controlling the battery to discharge for the power supply; when the discharging is finished, notifying the electrical signal tester to repeatedly measure the voltage and the current of the battery; according to the voltage values and the current values, which are measured when the charging is finished, generating a first life curve, and according to the voltage values and the current values, which are measured when the discharging is finished, generating a second life curve; judging whether the first and second life curves are coincided with corresponding critical life limit characteristic curves; when the first and second life curves are coincided with the corresponding critical life limit characteristic curves, generating a service reliability testing report of the battery; or when a certain curve is not coincided with the corresponding critical life limit characteristic curve, returning to the charging step. The invention also provides a system for testing the charge-discharge reliability of the battery. By utilizing the method and the system for testing the charge-discharge reliability of the battery, the service life of the battery can be automatically tested.

Description

technical field [0001] The invention relates to a battery testing system and method, in particular to a battery charging and discharging reliability testing system and method. Background technique [0002] Using a power supply to charge and discharge a battery is a well-known technology in the industry, and the life of the battery can be measured by the number of times of charging and discharging. The traditional method is to use hardware equipment to directly test the charge and discharge of the battery, or manually measure the data after the battery is charged and discharged by the power supply, and then compare it with a critical value to obtain the life of the battery. [0003] However, the hardware equipment for testing batteries is expensive, and the purchase of this hardware equipment will increase the cost for the company, while using manual measurement is cumbersome and has large errors. Contents of the invention [0004] In view of the above, it is necessary to ...
