Battery collection instrument and device for preventing collected battery set from short circuit

Abstract

The invention discloses a battery collecting instrument and a device used for preventing the battery set collected thereby from a short trouble, wherein the device used for preventing the battery set collected by the battery collecting instrument from the short trouble comprises a first decoder, a second decoder and an arithmetic unit; a digital control signal is coupled to the input terminals of the arithmetic unit and the first decoder, the output terminal of the arithmetic unit is coupled to the input terminal of the second decoder, the output terminal of the first decoder is coupled to one part of a control channel of a battery set, and the output terminal of the second decoder is coupled to another control channel of the battery set; the arithmetic unit is used for processing the digital control signal and leading the control channel where the trigger signal which is output by the second decoder is arranged and the control channel where the trigger signal which is output by the first decoder is arranged to be adjacent control channels, the arithmetic unit being a adder or a subtracter is controlled for enabling the digital control signal to shift one position or directly output, the output terminal of the first decoder is coupled to an odd number control channel of the battery set, the output terminal of the second decoder is coupled to an even control channel of the battery set, or the intput terminal of the first decoder is coupled to the even control channel of the battery set, and the output terminal of the second decoder is coupled to the odd control channel of the battery set. By using a hardware circuit, the invention ensures that only adjacent batteries of the collected battery set are conducted, thus preventing that the voltage which is input into the battery collecting instrument is over-high and avoiding the short trouble of the collected battery set.

Description

technical field

[0001] The invention relates to a device for preventing short circuit of a battery group collected by a battery collector, and also relates to a battery collector. Background technique

[0002] The internal resistance of battery collectors used in mobile computer rooms and UPSs is very small (less than 1 ohm), which can easily cause short circuits in the battery packs collected by the battery collector. Once the consequences of short circuit are very serious, it will bring heavy losses to customers. At present, battery collectors generally use software to switch channels to prevent battery packs from short-circuiting. However, the reliability of the software is far inferior to that of the hardware, especially when it is disturbed, channel switching errors will occur, resulting in a high voltage input to the battery collector, short-circuiting the battery pack, and damaging the battery collector. The existing method of using software to prevent short circuit...
