Typical Applications of CSR - Divided Container, Chemical Cabinet
CSR in the battery industry usually refers to the process of battery capacity division and formation, which is an important step in battery production. Capacity division is the process of determining the capacity and performance of a battery during the manufacturing process, through charge and discharge tests, to ensure consistency among the batteries in the battery pack. Transformation is the first charging process of a new battery, aimed at activating the chemical composition of the battery and stabilizing its performance.

CSR plays a major role in the application scenarios of split capacity cabinets and chemical cabinets
Battery testing and management: The chemical capacity divider is the core equipment for battery testing and management, used to conduct charge and discharge tests on batteries to evaluate their performance and lifespan. The market demand for these devices is growing rapidly, placing higher demands on the performance of connectors, such as high current transmission capability and anti loosening design, to ensure the accuracy and safety of testing.
Technological development: The technology of chemical separation equipment is constantly advancing, and new processes and equipment are developing towards improving accuracy, increasing efficiency, reducing energy consumption, and miniaturization. For example, Jingshi Electromechanical's third-generation high-voltage DC capacity water-cooled integrated machine and second-generation chemical integrated machine have achieved significant energy consumption reduction and system efficiency improvement through technological innovation.
Equipment efficiency: The charging and discharging efficiency, current and voltage accuracy, battery temperature, and internal temperature control level of the needle bed of the chemical and capacitive equipment have become important considerations for battery companies when choosing equipment. The design of equipment needs to consider factors such as maintenance convenience, automation level, and footprint to improve overall production efficiency.
Power system: The self-developed power system plays a crucial role in the charging and discharging efficiency, current and voltage accuracy of the equipment in the chemical capacity division section. The power supply design team of Jingshi Electromechanical has over 20 years of experience in power electronics design and development, and its self-developed power supply technology and design process are leading in the industry.
Smart Container: In the field of new retail, smart containers utilize technologies such as AI data, user profiles, and product recommendations to achieve a new type of consumer ecosystem loop. Through data-driven implementation, they achieve "thousands of containers and thousands of faces", improving user experience and service quality.
Battery capacity divider technology: The battery capacity divider is composed of multiple battery units, equipped with a controller, ammeter, and connector, used to monitor and control the charging and discharging process of the batteries. The capacity divider monitors the current and voltage of the battery through a controller, achieving a balance between charging and discharging, and also has fault protection function.
How does the current sensing resistor CSR affect the accuracy of battery testing in the dividing and forming cabinets?
The accuracy of current sensing resistors directly affects the accuracy of battery testing. The stability, temperature coefficient, and accuracy level of resistors are all factors that need to be considered when selecting. High precision and low temperature drift resistors can provide more accurate current measurements, thereby improving the reliability of battery testing.
How to calibrate the current sensing resistor CSR in the capacity divider cabinet and the conversion cabinet?
Calibrating current sensing resistors typically involves using a known current source and high-precision voltage measurement equipment to determine the actual voltage drop of the resistor. By comparing the actual measured values with the expected values, the system can be calibrated to ensure the accuracy of current measurement.
What common problems may be encountered with the current sensing resistor CSR in the distribution and conversion cabinets?
- Some common issues may include resistance drift, poor contact, overheating, damage, or aging. To ensure long-term stability, it is necessary to regularly inspect and maintain the resistance, as well as monitor its performance to ensure compliance with specifications.
What are the considerations for CSR in design?
Factors to consider during design include resistance value, power rating, temperature coefficient, packaging size, and cost. Low resistance values can reduce power loss, but may require more precise amplifiers. In addition, resistors with low temperature coefficients can provide more stable measurements, but the cost may be higher.
What are the possible problems that CSR may encounter in practical applications?
Possible problems encountered in practical applications include the influence of parasitic resistance, errors caused by PCB layout, and changes in resistance values due to environmental temperature fluctuations. To reduce these effects, Kelvin connections (four terminal connections) can be used to minimize the impact of parasitic resistance, and the performance of the signal chain can be optimized through carefully designed PCB layouts.
