SAE J2289 End-of-Life Testing of EV Battery Modules
The SAE J2289 standard provides a framework for evaluating the end-of-life (EOL) performance and condition of electric vehicle (EV) battery modules. This service is critical in ensuring that recycled materials from these batteries are reused efficiently, thus promoting sustainability and reducing environmental impact.
As quality managers and compliance officers, you will appreciate how SAE J2289 helps standardize the testing process to ensure consistency and reliability across different manufacturers and recycling facilities. For R&D engineers, this service offers a valuable tool for optimizing battery performance and lifecycle management. Procurement teams can rely on this service to verify that recycled materials meet quality standards before they are incorporated into new products.
The SAE J2289 testing protocol assesses various parameters of the EV battery modules including capacity retention, internal resistance, state-of-charge (SOC), and other relevant metrics. This ensures that batteries are accurately assessed for their remaining useful life, aiding in informed decisions regarding recycling or repurposing.
Our laboratory is equipped with advanced instrumentation to perform these tests, ensuring precise and reproducible results. The testing process involves thorough preparation of the battery modules, including conditioning to a known state-of-charge and discharging until a predetermined cut-off voltage. This meticulous approach guarantees accurate assessment of the battery's health at end-of-life.

Scope and Methodology
| Test Parameter | Description |
|---|---|
| Capacity Retention | Determines how much charge a battery can hold compared to its initial capacity. |
| Internal Resistance | Measures the electrical resistance within the battery, indicative of internal health. |
| State-of-Charge (SOC) | Assesses the battery's current charge level, useful for lifecycle management. |
| Cycling Capability | Evaluates the number of times a battery can be cycled before reaching its end-of-life. |
| Electrochemical Analysis | In-depth analysis of the battery's electrochemical properties to assess remaining life expectancy. |
| Thermal Stability | Tests for thermal stability and potential risks in recycling or repurposing. |
| Dissolution Studies | Evaluates the release of potentially harmful materials during recycling processes. |
The methodology involves several steps, beginning with the receipt of the battery module. Once received, it is conditioned to a known state-of-charge and discharged until specific cut-off voltages are reached. This ensures that all batteries tested start from an identical condition, which is crucial for accurate comparison.
Following conditioning, various tests are conducted according to SAE J2289 protocols. These include measuring capacity retention, internal resistance, state-of-charge, cycling capability, electrochemical analysis, thermal stability studies, and dissolution studies. Each test provides critical insights into the battery's health and remaining useful life.
The data collected from these tests is then analyzed using advanced software tools. The results are compiled into comprehensive reports that include recommendations for further actions based on the findings. These recommendations could range from immediate recycling to repurposing or extended use in less demanding applications.
