JIS C8712 Lithium-Ion Cell Performance Testing
The JIS C8712 standard specifies testing procedures for lithium-ion cells used in various applications, including portable electronics and electric vehicles. This service ensures compliance with Japanese industry standards by rigorously evaluating cell performance parameters such as internal resistance, capacity retention, and cycle life under controlled conditions.
Our laboratory adheres strictly to the JIS C8712 standard, providing a comprehensive suite of tests that assess the reliability and safety of lithium-ion cells. These tests are crucial for ensuring product quality and meeting regulatory requirements. Our expertise in this domain allows us to offer precise and accurate results, which are essential for manufacturers seeking to validate their products.
The testing process begins with thorough preparation of the lithium-ion cells according to the specified standards. This includes charging the cells to a known state-of-charge (SOC), ensuring uniformity among test samples, and verifying that all equipment is calibrated correctly. Once prepared, the cells undergo a series of tests designed to simulate real-world usage conditions.
One key aspect of our testing procedure involves assessing the internal resistance of the cell using an impedance analyzer. This measurement provides insight into the health and efficiency of the cell, helping to identify any issues that may arise during operation. Additionally, we perform capacity retention tests to determine how well the cell maintains its initial capacity over multiple charge-discharge cycles.
Cycle life testing is another critical component of our JIS C8712 Lithium-Ion Cell Performance Testing service. This test evaluates the longevity and durability of the cells by subjecting them to repeated charge-discharge cycles until failure or a predetermined number of cycles are reached. The results from these tests provide valuable data on the cell's performance under stress conditions, which is essential for predicting its lifespan in end-user applications.
Our laboratory also conducts safety-related tests as part of the JIS C8712 standard. These tests ensure that the cells meet stringent safety requirements by assessing their behavior during overcharge, overdischarge, and short-circuit events. By simulating these scenarios, we can identify potential risks early in the development process, enabling manufacturers to take corrective actions if necessary.
In addition to evaluating individual cell performance, our service encompasses testing entire battery modules or packs. This broader assessment allows us to provide a holistic view of the system's reliability and safety features. By examining how multiple cells interact within the module during charging and discharging cycles, we can uncover any inconsistencies that could impact overall performance.

Scope and Methodology
The scope of JIS C8712 Lithium-Ion Cell Performance Testing includes a range of tests designed to evaluate the performance characteristics of lithium-ion cells. These tests are carried out using industry-standard equipment and procedures, ensuring consistent results across different manufacturers.
- Internal resistance measurement
- Capacity retention testing
- Cycle life evaluation
- Safety-related assessments (overcharge, overdischarge, short-circuit)
- Module or pack level performance analysis
The methodology employed in our laboratory follows the guidelines outlined in JIS C8712. This includes precise control of environmental conditions such as temperature and humidity to minimize variability between tests. We also ensure that all tools and instruments are regularly calibrated against reference standards, further enhancing accuracy.
For internal resistance measurement, we use an impedance analyzer capable of providing sub-microohm resolution. This precision allows us to detect even minor changes in the cell's electrical characteristics, which can indicate early signs of degradation or failure.
In capacity retention testing, cells are cycled through multiple charge-discharge cycles while monitoring their ability to retain their original capacity. The number of cycles varies depending on the specific requirements set forth by JIS C8712; typically ranging from 500 to 3,000 cycles.
The cycle life evaluation involves subjecting cells to repeated charge-discharge cycles until they reach a predetermined threshold or fail prematurely due to internal failure. This process provides valuable information about the cell's endurance and reliability under typical usage conditions.
Safety-related assessments are conducted by simulating various abuse scenarios, such as overcharging beyond the recommended limits, discharging below minimum voltage thresholds, and applying excessive current during charging/discharging processes. These tests help identify potential weak points in the design that could lead to hazardous situations if not addressed promptly.
Module or pack level performance analysis involves examining the interaction between individual cells within a larger assembly like a battery pack. This evaluation helps determine how well each cell contributes to the overall functionality and stability of the system during charging and discharging operations.
