Abstract

The invention discloses a battery test circuit and a battery short circuit test apparatus. Through a line control device, a tester can control the anode and the cathode of a tested battery to be connected in a short circuit out of a safety distance for a short circuit test. By using the test circuit, the tester can be away from the battery during the short circuit test, thus the personal safety of the tester is guaranteed.

Description

technical field [0001] The invention relates to the field of circuits, in particular to a battery test circuit and a battery short-circuit test device. Background technique [0002] At present, various types of batteries, especially storage batteries, are widely used in various products such as lamps, uninterrupted power supply (Uninterrupted Power Supply, UPS), and solar inverters. These products have high requirements on the reliability of the battery. Before the product leaves the factory, a series of safety tests must be done on the battery. Among them, the short-circuit test of the battery is a very important test content. The short-circuit test is to directly short-circuit the positive and negative electrodes of the battery through wires. When the battery is short-circuited, a large current flows through the wires and releases huge energy. Therefore, explosions and fires may occur during the short-circuit test, which may endanger the personal safety of the test personn...
