Energy storage battery pack vibration standard

What is vibration durability testing?

This SAE Recommended Practice describes the vibration durability testing of a single battery (test unit) consisting of either an electric vehicle battery module or an electric vehicle battery pack that is typically greater than 200 kg in mass and structurally integrated as part of the vehicle.

What are the environmental requirements for a battery pack?

The battery pack was subjected to extensive environmental testing, such as temperature, vibration, and humidity. This is discussed in Section IV. Safety is one of the most important requirements of automotive battery packs, as discussed in Section V.

What are the electrical characteristics of a battery pack?

Electrical characteristics of a battery pack reveal its ability to deliver consistent power and energy throughout its lifespan. The battery system should be stable under different conditions, and consider the minimization of the battery pack aging effects to preserve performance and reliability.

What is a battery pack?

The battery pack is an independent subsystem at the vehicle level that was tested separately. The unit should be able to operate under different electrical and environmental conditions considering safety concerns and regulations. Hence, the battery unit is enclosed by a metallic enclosure that can survive different test cases such as vibrations.

How secure is a battery pack?

Based on the findings from the simulated fatigue assessments, the battery pack design is mostly secure, apart from specific regions of the support frames and mounting plate. Zhang X et al. 14 introduced a dual-goal optimization technique to assess the crushing stress and the vibration fatigue duration of the battery pack system.

What are the standards for a battery pack?

There are few standards addressing topics such as ISO7637_1 ; ISO7637_2 ; ISO7637_3 , but as mentioned, more work or regulations are needed. The battery pack, as an individual component with connectors and interfaces, including all cells and electronics, has acceptable EMC behavior, as defined in relevant standards.
