1. The application range and selection of high-precision current sensors are very important.

Current sensors are detection devices that can sense the information of the measured current and convert the detected information into electrical signals or other forms of information output to meet certain standards, fulfilling the needs for information transmission, processing, storage, display, recording, and control.

1. Application range of high-precision current sensors:

Widely applicable in fields such as electricity, communication, meteorology, railways, oil fields, metering, scientific research and teaching units, high-precision AC leakage current in industrial and mining enterprises, and can connect various high-precision digital multimeters, data loggers, power quality analyzers, oscilloscopes, industrial control instruments, etc. for current, frequency, phase, power, and energy measurement.

2. Characteristics of high-precision current sensors:

1. Multi-layer shielding technology, almost unaffected by external magnetic fields, while having waterproof, rainproof, and drip-proof functions, ensuring high-precision online monitoring, uninterrupted throughout the year, high stability, and high reliability.

2. Can be customized according to user requirements to meet more usage scenarios.

3. Basic performance differences are minimal, whether in open-loop or closed-loop principles, with fast response time, low temperature drift, high precision, small size, wide bandwidth, strong anti-interference ability, and strong overload capacity.

3. How to choose a high-precision current sensor

1. Pay attention to whether the hole size can ensure that the wire can pass through the sensor.

2. Check if there are high temperatures, low temperatures, high humidity, or special environments such as strong vibrations in the application environment.

3. Ensure that the spatial structure meets the requirements.

2. Application of high-precision current sensors in battery equipment

From the vision of the dual carbon goals and the direction of building a new power system dominated by new energy, it can be seen that the development of energy storage business in China is entering a fast track. The rise of energy storage has led to an increasing market demand for energy storage equipment and higher requirements for innovation and reform in energy storage technology. Due to the high energy density, long service life, high power carrying capacity, light weight, strong adaptability, and the absence of toxic heavy metals and substances such as lead, mercury, and cadmium, lithium batteries have become the preferred choice for energy storage. Good manufacturing technology and techniques have become key to ensuring the performance advantages of lithium batteries. Battery components play a crucial role in the production process of lithium batteries, directly affecting the efficiency, cycle life, thermal stability, and safety performance of lithium batteries.

Component capacity equipment

Generally speaking, the battery manufacturing process is divided into constant current charging, constant voltage charging, constant power charging, constant current discharging, constant power discharging, and constant power discharging stages. The battery manufacturing process has high requirements for the measurement accuracy of charging and discharging current and voltage of lithium batteries, thus requiring current sensors with higher precision to ensure that chemical equipment meets high requirements and standards in overall accuracy. In addition, the chemical process also has strict temperature requirements, so the temperature drift performance of high-precision current sensors is also very important.

High-precision current sensors greatly improve the overall reliability and safety of equipment and are widely used in chemical equipment.

Generally, it refers to implementing a series of technical measures on the initially charged battery to stabilize its performance, including small current charging and discharging, constant temperature static, etc. Activating the battery involves charging it with a small current to activate the internal positive and negative materials, forming an SEI film on the negative surface, making the battery performance more stable. The battery can only reflect its true performance after conversion. If the battery is not converted, it cannot charge and discharge normally.
