Testing that Reaches the World

At Clark Testing, we understand the critical role that battery performance plays in the success of electric vehicles and other eMobility applications. That's why we offer a suite of advanced testing services designed to ensure the reliability, safety, and efficiency of eMobility batteries throughout their lifecycle.

Testing standards for e-mobility can vary depending on the region and the specific application.  At Clark Testing, we recognize the pivotal role that battery technology plays in driving the evolution of electric vehicles (EVs) and hybrid electric vehicles (HEVs).  There are several widely recognized international standards that are commonly used in the testing and certification of batteries for electric vehicles. Some of these standards include:

UN ECE Regulation 100: This regulation outlines the uniform provisions concerning the approval of vehicles with regard to specific requirements for electric powertrains, including battery systems.

IEC 62660 series: This series of standards from the International Electrotechnical Commission (IEC) provides requirements and testing methods for rechargeable lithium-ion batteries for use in electric vehicles.

ISO 12405 series: These standards from the International Organization for Standardization (ISO) cover testing procedures for lithium-ion traction battery packs used in electric vehicles.

SAE J2464: This standard from the Society of Automotive Engineers (SAE) specifies the test procedures for lithium-ion battery packs used in electric and hybrid-electric vehicles.

IEC 62133: This standard specifies requirements and tests for the safe operation of portable sealed secondary lithium cells and batteries.

ISO 26262: While not specific to batteries, this standard from ISO addresses functional safety aspects of electrical and electronic systems within road vehicles, including electric vehicles.

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.
