Battery Pack and Cell Testing
Batteries are most important component of any electrical & electronic equipment. Their safety, quality, compliance & performance is majorly dependent on batteries. Electric Vehicles (EVs) being future of transport & batteries being key component of any EV, it is essential that they are tested & certified. We at ATS TEST LAB support our customers for Testing of batteries as per various national & international regulations as well as standards. Our battery testing services are applicable to an extensive range of applications such as electric vehicles, stationary batteries, grid storage, grid balancing, backup applications, uninterruptable power supplies (UPS), medical devices, e-bikes etc. Battery safety and reliability is also a key concern for the renewable energy industry, which utilizes a wide range of technologies for solar energy storage and other uses
Testing at the Component Level: Understanding the nuances of testing battery cells, modules, packs, and BMUs is crucial for ensuring product quality, performance, and safety. Automated testing equipment, environmental chambers, and advanced data acquisition systems are integral to this process, providing the precision and repeatability needed to meet stringent quality standards in the battery manufacturing industry.
Cell-Level Testing: Battery cell testing focuses on individual cells before integration into larger modules or packs. This early-stage testing helps identify defective or subpar cells.
Cell testing typically includes:
Voltage – Measured under various load conditions.
Capacity – Determining the energy storage capability.
Internal Resistance – Indicating cell health and performance.
Cycle Life – Estimating the number of charge and discharge cycles the cell can endure.
Pack-Level Testing: Battery pack testing evaluates the overall performance and safety of a complete battery system, often subjecting it to rigorous conditions to simulate real-world usage.
Test scenarios for pack testing in the lab includes:
Environmental Testing – Evaluating performance in extreme temperatures, humidity, and altitude.
Abuse Testing – Simulating physical damage, overcharging, and short circuits.
Life-Cycle Testing – Assessing long-term durability and reliability under operational conditions.
