Problems solved by technology

During the operation of the DC system, if the battery with degraded performance or damage is not dealt with in time, it will cause the battery pack to open circuit or even lead to the collapse of the entire DC system
[0003] Due to the limitations of existing technology, the current main method is to shut down the DC system, remove or replace the damaged battery and then put it into operation, but this method will affect the continuous power supply of the DC system

Embodiment 1

[0029] The present invention provides a jumper device for batteries, which is used to measure the voltage of the battery under test and replace the battery under test with degraded or damaged performance, such as figure 1 As shown, a controller U1 is provided in the jumper device, and the input terminal of the controller U1 is connected with a reference voltage unit that provides a reference voltage for the controller U1 and a measurement unit for measuring the voltage of the storage battery under test. A battery short-circuit unit is connected to the input end of the measuring unit;

[0030] The output end of the controller U1 is connected with an optocoupler isolation drive circuit for isolating its own input and output signals, and the output end of the optocoupler isolation drive circuit is connected with the battery short-circuit unit;

[0031] The jumper device also includes a power supply unit for supplying power to the jumper device;

[0032] Among them, the battery s...

Abstract

The invention provides a bridging device used for storage batteries. The bridging device belongs to the field of power equipment, and comprises a controller U1 and a power supply unit, wherein an input end of the controller U1 is connected with a reference voltage unit and a measuring unit, and an input end of the measuring unit is connected with a battery short-circuit unit; an output end of thecontroller U1 is connected with an optocoupler isolation driving circuit, and an output end of the optocoupler isolation driving circuit is connected with the battery short-circuit unit; the battery short-circuit unit comprises a thyristor VS; and the power supply unit supplies power to the bridging device. According to the bridging device, the optocoupler isolation driving circuit drives the thyristor VS after determining that an anode and a cathode of the thyristor VS are normally connected with positive and negative electrodes of a measured storage battery by means of the controller U1, sothat the storage battery pack can continue to maintain operation of a DC system by means of the thyristor VS, the measured storage battery is safely isolated, and the purpose of putting a new storagebattery into operation after safely removing or replacing the measured storage battery without affecting a continuous power supply state of the DC system is realized.

Description

technical field [0001] The invention belongs to the field of electric equipment, in particular to a jumper device for storage batteries. Background technique [0002] The battery is the core equipment of the DC system. During the operation of the DC system, if the battery with degraded performance or damage is not dealt with in time, it will cause the battery pack to open circuit or even cause the entire DC system to collapse. [0003] Due to the limitation of existing technology, the current main method is to shut down the DC system, remove or replace the damaged battery and then put it into operation, but this method will affect the continuous power supply of the DC system. Contents of the invention [0004] In order to solve the shortcomings and deficiencies in the prior art, the present invention provides a jumper device for removing or replacing a damaged storage battery online. [0005] In order to achieve the above-mentioned technical purpose, the present inventio...
