Embodiment Construction

[0030] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Like numbers refer to like elements throughout the drawings.

[0031] figure 1 It is a structural block diagram of a testing device for testing a battery protection circuit module according to the present invention.

[0032] Such as figure 1 As shown, the testing device includes a battery replacement part 10 , a circuit load part 20 , a detection / control part 30 , a selection part 40 , a battery protection circuit module assembly part 50 and a charger replacement part 60 .

[0033] The battery replacement unit 10 works like a battery, providing DC voltage to each battery protection circuit module.

[0034] The circuit load part 20 works like a load, thereby consuming the current supplied by the battery replacement part 10 .

[0035] The detection / control unit 30 includes at least one program to check the normal operation...

Abstract

The present invention introduces testing device and method used for testing a plurality of Battery protection circuit modules to be tested at the same time. Said testing device includes virtual power cells, a virtual charger and virtual loads. By applying the testing device in accordance with the present invention, one can execute tests for a plurality of tests such as over charging electric voltage detection, over charging load bearing electric voltage detection, overdischarging electric voltage detection, overdischarging load bearing electric voltage detection, rechargeable/redischargeable performances and excessive voltaic blocking capability, at short time and according to programmable controllers. In accordance with the present invention, the battery protection circuit module is not be departed during a test process, then the hand-manipulated time is very short and the test can be completed very safely. Therefore, the total test time is shortened.

Description

technical field [0001] The invention relates to a testing device and a method for automatic testing of battery protection circuit modules. Background technique [0002] The battery protection circuit module is used to protect the battery from explosion, overheating, leakage or degraded in battery characteristics by preventing the battery from overcharging, overdischarging, current overload, short circuit, reverse bias (reverse bias), thereby prolonging the battery life. battery life. In addition, the battery protection circuit module improves the charging / discharging efficiency of the battery and suppresses explosion, leakage and overheating of the battery. [0003] Usually, according to conventional techniques, 20 to 60 battery protection circuit modules are arranged in the same substrate, such as figure 1 shown. Then, one or more battery protection circuit modules are used to test their normal operation respectively. A single battery protection circuit module can be pu...
