Testing that Reaches the World

At Clark Testing, our innovative testing facilities are dedicated to ensuring the performance, reliability, and safety of automotive batteries, empowering manufacturers to deliver vehicles that meet industry standards and customer expectations. Our team of engineers leverage our test instrumentation and experience to conduct a comprehensive range of tests, including UN 38.3 and IEC 62133, on automotive batteries. From performance validation to thermal management assessments, our testing procedures are developed to address the test validation demands of the automotive sector.

Clark’s customer-oriented approach, enables us to partner with companies to achieve their product development objectives and production goals in the EV industry. We work with our customers to develop a comprehensive test plan ensuring compliance testing to UN 38.3 or IEC 62133 standards. We then implement the test plan while maintaining consistent customer communication regarding the program status.

At the end of the test program, the test engineer will issue a detailed report enabling our clients to make informed decisions and drive continuous improvement with their automotive battery technologies. Whether you're a battery developer or system integrator, Clark Testing is your go-to partner for elevating the performance and reliability of automotive batteries in the EV industry.

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.
