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.
What are the requirements of automotive battery packs?
Safety is one of the most important requirements of automotive battery packs, as discussed in Section V. The battery pack should be electrically and mechanically safe, and different criteria should be fulfilled as required by the standards. Functional safety is also the main tool for realizing the requirements mentioned.
What are the charging and discharging requirements of a battery pack?
The charging and discharging requirements of the battery pack are directly related to the power demand by the electric motors and the charging time. The battery pack design shall be such that it could meet the required maximum power in traction and regeneration modes. In addition, the charging power is a critical factor for the end users.
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.
Is a battery pack suitable for aviation?
The classical structure of a battery pack is inappropriate for aviation. It is not possible to disconnect the battery pack in the case of an extreme fault, and new architectures are required. In addition, the environmental conditions are harsher and packaging may be more challenging.
