Mechanical Testing EV Batteries

As the automotive industry reaches the critical juncture between pursuing gas-powered or electric vehicle (EV) production, ATS supports manufacturers with mechanical testing for EV batteries with our reliable and qualified lab. Our A2LA-accredited lab helps engineers anticipate an EV battery’s response to normal operating conditions, such as vibration and force.
Before releasing a battery for mass production and distribution, EV battery manufacturers and engineers may request mechanical tests as part of larger business processes:
  • Quality assurance
  • Safety testing
  • Standard and regulation compliance
Mechanical Testing
ATS uses mechanical testing to determine an EV battery’s properties and assess functionality. We deliver precise measurements and thorough analysis using powerful technology and experts with decades of experience. We follow OEM instructions when planning the test method. The appropriate mechanical test depends on the battery manufacturer, application, and materials.
Impact Testing
Impact testing measures the battery’s impact strength: its ability to withstand a sudden impact during normal operation. A simple and cost-effective procedure, Charpy impact testing measures how much energy is needed to fracture a battery so product designers can decide whether a product is ready for distribution or redesign.
For vehicles operating in low-temperature environments, our experts can incorporate temperature analysis into the Charpy test to study the battery’s ductile to brittle transition temperature (DBTT), at which the battery shatters upon impact.
Vibration Testing
ATS provides vibration testing to help manufacturers evaluate a battery’s ability to handle road conditions. Throughout their life cycle, batteries experience multiple and simultaneous types of vibrations, from idling in traffic to driving over an unpaved road. Vibration tests can simulate normal operating conditions to uncover a battery’s hidden defects and vulnerabilities.
Vibration testing measures vibration resistance, a material’s ability to withstand shock and vibrations without failing. Our vibration testing labs can subject a battery sample to rigorous vibrations, including:
  • Sine
  • Random
  • Shock
  • Sine on Random
Tensile Testing
Manufacturers and engineers request tensile testing to assess if a battery can withstand the tensile forces associated with normal conditions. Tensile testing measures tensile strength, the resistance to stretching. During a tensile test, a tensile machine induces a gradually increasing stretching force until the battery breaks. This test measures how much tensile force is needed to break the battery.
  • Maximum force capacity of 400,000 pounds
  • Maximum temperature 1800 ˚F
Compression Testing
During operation, a battery may undergo compressive or crushing forces. During a compression test, our experts exert a gradually increasing compressive force on the battery until it collapses. We use this test to measure the battery’s compressive strength so manufacturers can ensure the device’s ability to endure typical compressive forces during operation.
