Description

Technical Field

[0001] The utility model relates to the technical field of secondary batteries, in particular to a voltage detection device for preventing reverse connection of an energy storage battery module. Background Technique

[0002] An energy storage battery module refers to a modular battery assembly formed by combining multiple battery cells together for storing energy or supplying power. It has the following advantages: high capacity flexibility, different capacity energy storage battery modules can be realized by combining different numbers of battery cells to meet different needs; easy to maintain, the modular design makes maintenance more convenient, and faulty battery cells or modules can be replaced individually without affecting the entire system; good safety, the modular design can better control the isolation and safety between battery components and reduce safety risks caused by single-cell failures; strong scalability, the number of modules can be flexibly increased or decreased according to needs to achieve system expansion or reduction.

[0003] An energy storage battery module usually consists of components such as battery cells, connectors, and a battery management system (BMS). Through reasonable design and assembly, a complete energy storage system is formed. Accordingly, during the assembly process of the energy storage battery module, it is necessary to pay full attention to the distinction between the positive and negative poles to avoid incorrect or reverse connection, otherwise serious safety hazards will be brought.

[0004] Currently, when detecting the polarity of an energy storage battery module, a voltmeter is generally used for detection. Since the voltmeter has no polarity requirement and can be randomly connected to the positive and negative poles of the module, only when the positive and negative poles are reversely connected, the voltage is negative. However, if the tester may be negligent and not notice, serious safety hazards will be brought. Content of the Utility Model

[0005] The purpose of the utility model is to provide a voltage detection device for preventing reverse connection of an energy storage battery module, which has the characteristics of high safety, simple structure, and convenient operation.

[0006] The utility model can be realized through the following technical solutions:

[0007] The utility model discloses a voltage detection device for preventing reverse connection of an energy storage battery module, which includes a voltmeter. A positive detection pen and a negative detection pen are respectively connected to the voltmeter. The voltmeter is simultaneously connected in parallel with a buzzer alarm. The buzzer alarm gives a buzzer alarm when the positive detection pen, the negative detection pen and the energy storage battery module are reversely connected.

[0008] Further, the negative electrode of the buzzer alarm is electrically connected to the positive electrode of the voltmeter, and the positive electrode of the buzzer alarm is electrically connected to the negative electrode of the voltmeter. Specifically, the positive and negative electrodes of the buzzer alarm are respectively opposite in polarity to the negative detection pen and the positive detection pen. When the polarity is normal, the buzzer alarm does not alarm due to the reverse connection of the polarity; when the positive detection pen, the negative detection pen and the energy storage battery module are reversely connected in polarity or the internal connection of the energy storage battery module is reversed, at this time, the voltmeter shows a negative value, and at the same time, the positive and negative polarities of the buzzer alarm are just correct, and a buzzer alarm is issued to prompt the employee to confirm and check to ensure its reliability.

[0009] Further, the voltage range of the buzzer alarm is 10 - 85V, which meets the voltage detection requirements of conventional different energy storage battery modules.

[0010] Further, both the voltmeter and the buzzer alarm are integrally arranged inside the detection box body, and the detection box body is respectively provided with a positive connection port and a negative connection port for movably plugging and unplugging connection with the positive detection pen and the negative detection pen. By setting the detection box body, the volume of the detection device is compactly controlled; through the pluggable connection, it is convenient for storage and operation.

[0011] Further, the detection box body is provided with a liquid crystal display screen for voltage display, and the liquid crystal display screen is an LED screen or an LCD screen to achieve visual display.

[0012] Further, the detection box body is provided with a number of honeycomb-shaped speaker holes to emit an effective alarm sound.

[0013] Further, the energy storage battery module is a lithium-ion battery module or a sodium-ion battery module, which meets the usage requirements of different secondary batteries.

[0014] Further, the cell type of the lithium-ion battery module is a lithium iron phosphate cell, a lithium manganese oxide cell, a ternary material cell or a lithium cobalt oxide cell, which meets the usage requirements of different lithium-ion batteries.

[0015] Further, the cell type of the sodium-ion battery module is a layered oxide material cell, a Prussian blue material cell or a polyanion-type material cell, which meets the usage requirements of different sodium-ion batteries.

[0016] Further, in the energy storage battery module, a number of cells are electrically connected and configured by series-parallel connection, with high flexibility.

[0017] The voltage detection device for preventing reverse connection of an energy storage battery module of the present utility model has the following beneficial effects:

[0018] First, high safety. By adding a buzzer alarm, according to its connection relationship with the voltmeter, when the voltage detection pen is connected reversely to the polarity of the energy storage battery module, the buzzer alarm will sound to remind the staff to check whether it is the detection pen that is connected reversely or the internal lead of the energy storage battery module is connected reversely to the shell polarity, avoiding potential safety hazards;

[0019] Second, simple structure. The anti-reverse connection voltage detection device of the present invention only needs to add a buzzer alarm on the basis of the original voltmeter to realize real-time detection and warning for the entire detection process, effectively simplifying the device composition;

[0020] Third, convenient operation. The anti-reverse connection voltage detection device of the present invention still maintains the original pen tip voltage measurement operation, without any special requirements for the operation process, and the operation is more simple and convenient.
