Embodiment 1

[0029] Such as figure 1 as shown, figure 1 It is a circuit diagram of the battery short-circuit circuit of the present invention, and the battery short-circuit circuit is used for the battery short-circuit test. The short-circuit circuit includes: a switch module 1 for controlling the power-on / power-off state of the battery short-circuit circuit; a short-circuit module 3 for performing a short-circuit operation on the battery to be tested; Timing module 2 for measuring battery for short-circuit operation; wherein, in the energized state of the battery short-circuit circuit, switch module 1 transmits a closing signal to timing module 2: timing module 2 starts timing after receiving the closing signal, and outputs a current signal at the same time to start the short-circuiting module 3 Perform short-circuit operation on the battery to be tested connected to the short-circuit module 3; stop timing when the timing duration of the timing module 2 reaches the preset delay time, and...

Embodiment 2

[0042] Such as figure 2 as shown, figure 2 It is a circuit diagram of the battery short-circuit circuit of Example 2 of the present invention, which is also used in the battery short-circuit test. Different from Embodiment 1, the battery short-circuit circuit also includes an alarm module 4 . Therefore, in addition to the functions of automatic short circuit and automatic short circuit stop involved in embodiment 1, embodiment 2 can also execute an alarm action when the short circuit of the battery to be tested is completed, and remind relevant personnel to pay attention. The alarm module 4 is also controlled by the timing module 2; specifically, in the energized state of the battery short-circuit circuit, the timing duration of the timing module 2 reaches the preset delay time and starts the alarm module 4 to perform an alarm action.

[0043] The alarm module 4 of this embodiment includes an alarm SP1 , a switch circuit 41 and a power supply circuit 42 . see figure 1 , ...

Abstract

The invention relates to short-circuiting circuits, and discloses a battery short-circuiting circuit and a battery short circuit testing method. The battery short-circuiting circuit comprises a switching module, a short-circuiting module and a timekeeping module, wherein the switching module is used for controlling a connection state and a disconnection state of the battery short-circuiting circuit, the short-circuiting module is used for short-circuiting a battery to be tested, and the timekeeping module is used for controlling the short-circuiting module to conduct the short-circuiting operation on the battery to be tested when the battery short-circuiting circuit is in the connection state. When the battery short-circuiting circuit is in the connection state, the switching module transmits a closing signal to the timekeeping module, the timekeeping module receives the closing signal and starts timekeeping, then the short-circuiting module is started to conduct the short-circuiting operation on the battery to be tested, and after the timekeeping period of the timekeeping module reaches a preset delay time, the timekeeping stops, and the short-circuiting module terminates the short-circuiting operation on the battery to be tested. According to the battery short-circuiting circuit and the battery short circuit testing method, automatic short circuit and automatic stop of the short-circuiting operation on the battery to be tested can be realized. The battery short-circuiting circuit is simple, reliable, high in safety and stable in testing efficiency. The battery short circuit testing method is convenient and easy to operate, high in safety and capable of improving the efficiency of the short-circuiting operation.

Description

technical field [0001] The present invention relates to a battery short-circuit circuit, and more particularly, to a battery short-circuit circuit and a battery short-circuit testing method. Background technique [0002] Lamp lighting can be seen everywhere in modern society, and battery discharge lamps are also a common lighting fixture. This type of lighting fixture has high reliability requirements on the performance of the battery; in the production process, it is usually necessary to conduct some destructive tests on the battery, such as performing a high-current discharge operation on the battery. The instantaneous current of the battery can reach dozens of amperes during high-current discharge, and the instantaneous current of high-current discharge with direct short circuit can even reach hundreds of amperes. In the prior art, in the destructive test of direct short-circuiting of the battery, the experimenter uses wires to directly short-circuit the two poles of the...
