Scope and Methodology
The scope of DIN EN 62620 environmental stress testing covers a wide range of tests designed to evaluate the durability and reliability of large lithium-ion cells. These tests are essential for ensuring that batteries perform consistently across diverse operating conditions, particularly in applications where safety is critical.
Testing typically begins with preparation steps such as charging/discharging cycles according to specified protocols before subjecting the cells to various environmental stresses like temperature cycling, humidity exposure, and thermal shock cycles. Each test parameter has specific ranges and durations defined by DIN EN 62620 which must be strictly adhered to.
During testing, real-time monitoring of key performance indicators (KPIs) is conducted using advanced instrumentation designed specifically for large cell sizes. KPIs include but are not limited to voltage levels, internal resistance values, and Coulombic efficiency metrics. These measurements provide valuable insights into the health state of the cells throughout the entire test cycle.
Upon completion of each stress condition, visual inspections are performed to check for any physical changes or signs of deterioration in the cells' appearance. Additionally, electrical performance tests are carried out post-stress exposure to assess whether there has been a significant change from initial readings. If any deviations exceed acceptable thresholds outlined by DIN EN 62620, corrective actions may be recommended based on observed anomalies.
The results of these comprehensive evaluations are summarized in detailed reports that document all relevant data points including raw measurements and graphical representations illustrating trends over time. These reports serve as authoritative references for quality assurance teams responsible for maintaining product integrity throughout development cycles or production runs. Furthermore, they offer actionable recommendations aimed at addressing identified weaknesses through iterative improvements.
