Is the pack battery safe

In this edition of our Battery Safety series, we will focus on the safety considerations concerning a single battery pack assembly. The first safety consideration is structural integrity, as the whole pack constitutes a significant mass.

The design for the safety of the whole pack is an integration of all the subsystems into one single unit. Mechanical design, high- and low-voltage electrical design, sensors, pumps, valves, and all the elements of thermal management together, form the basis of the whole battery pack design and development.

The lithium-ion battery is one of the most vulnerable battery types in the sense that any voltage, current, temperature, or short circuit fluctuation can lead to a catastrophe. The most viable way to enforce the safety and security of battery packs is via integration with the battery management system.

The first safety consideration is structural integrity, as the whole pack constitutes a significant mass. The strength and stiffness are unquestionably important as the mass influences the way the battery pack structurally behaves, both separate from the vehicle and when installed in the vehicle.

Never burn, overheat, disassemble, short-circuit, solder, puncture, crush or otherwise mutilate battery packs or cells. Do not put batteries in contact with conductive materials, water, seawater, strong oxidizers and strong acids. Avoid excessively hot and humid conditions, especially when batteries are fully charged.

The hardest and most hidden threat of the battery pack is fire. No manufacturer or EV driver would ever think about their battery energy storage systems catching fire. This type of catastrophe may sometimes arise from sparking or burning due to the manufacturing defects such as internal short circuits.
