Testing Services:

• Load Testing: Simulates a full load to measure the battery’s performance under actual operating conditions.
• Voltage Testing: Measures the voltage levels to identify weak or failing cells.
• Impedance Testing: Assesses internal resistance to predict battery life and potential failures.
• Charge-Discharge Testing: Batteries undergo repeated charge-discharge cycle test to determine the number of cycles the battery can endure while maintaining specified performance levels.
• Capacity Testing: Batteries are tested to determine their actual capacity compared to their rated capacity ensuring that the batteries meet the required energy storage specifications.
• Short Circuit Testing: Batteries are subjected to short circuit conditions to evaluate their safety features and the ability to withstand internal faults without prompting failures.
• Dielectric Testing:  Dielectric testing known as high potential test, hipot test, or insulation test applies a high level of voltage to the insulation barrier and measure the reaction.
• Isolation Testing:  Isolation testing ensures batteries are free from unwanted electrical connections that could lead to short circuits particularly in high-voltage applications.
• Overcharge Testing:  Overcharge testing is vital, particularly for Lithium-Ion batteries, for ensuring the safe use in consumer electronics, electric vehicles, eMobility, industrial, military and other applications.
• Seismic Testing: Simulates the operating environment ensuring the battery generator, battery back-up or UPS system will operate despite the effects of an earthquake.
• Vibration Testing: Batteries are subjected to a vibration profile emulating the vibration cycle in the field of operation.
• Mechanical Shock Testing: Batteries are subjected to mechanical shocks to verify the structural integrity of the battery housing and its components.
• Destructive/Abuse Testing:  Batteries are subjected to thermal runaway, drop test, penetration test and crush test to assess how batteries react to harsh conditions
• Electromagnetic Compatibility (EMC/EMI) Testing: Batteries are tested for electromagnetic emissions and interference to ensure they do not interfere with other electrical and electronic systems.
• Thermal Cycling: Batteries undergo heating and cooling cycles simulating the thermal stress determining the reaction to standard and critical operating conditions.
• Material & Chemical Analysis:  Clark provides a complete profile of the elemental analysis and chemical properties of the base raw materials and battery cell.
