Abstract

The embodiment of the invention discloses a battery status detection device, applicable to being respectively connected with a battery pack and a DC / DC conversion circuit. The battery status detectiondevice comprises a voltage attenuator, an addition synthesizer and a status detection unit, the DC / DC conversion circuit comprises an input terminal, a feedback terminal and an output terminal, the input terminal is connected with the battery pack, the feedback terminal is connected with the addition synthesizer, the output terminal is connected with the addition synthesizer, the status detectionunit and electric equipment, the voltage attenuator is connected between the battery pack and the addition synthesizer, the DC / DC conversion circuit is applicable to receiving a battery voltage via the input terminal, receiving a feedback voltage via the feedback terminal and outputting an output voltage via the output terminal; the voltage attenuator is applicable to attenuating the battery voltage and outputting the attenuated voltage; the addition synthesizer is applicable to synthesizing the output voltage and the attenuated voltage and outputting the feedback voltage to the DC / DC conversion circuit, so that the output voltage can be conveniently controlled; and the status detection unit is applicable to determining a battery status of the battery pack according to the output voltage.

Description

technical field [0001] The invention relates to the technical field of state detection, in particular to a battery state detection device. Background technique [0002] In industrial sites, many important key electrical equipment are powered by batteries. For some electrical equipment that is powered by batteries and has explosion-proof requirements, the batteries must be isolated in a sealed explosion-proof box, and the box cannot be opened at will to prevent explosion accidents caused by electric sparks generated by the battery. [0003] That is to say, the battery explosion-proof box and the electrical equipment are independent of each other, and the battery cannot be directly connected to the subsequent circuit. Although this ensures safety, it also makes it impossible to directly obtain the battery status. Once the battery power is too low or the battery is damaged, the electrical equipment cannot work normally, which may cause unpredictable losses. Therefore, it is ...
