When designing a battery pack / system it is important to think about and describe the safety concept. This will allow you to understand and show the layers of safety designed in physically or into the control system. The first thing is to look at the specification of the individual battery cell as this will specify the limits of safe operation:
Robust mechanical design and battery packaging can provide greater degree of protection against all of these. This chapter discusses design elements like thermal barrier and gas exhaust mechanism that can be integrated into battery packaging to mitigate the high safety risks associated with failure of an electric vehicle (EV) battery pack.
As an example, a 24V lithium-ion battery pack typically has six cells connected in series. Many battery packs have built-in circuitry used to monitor and control the charging and discharging characteristics of the pack.
The choice of thermal barrier materials (TBMs) for a battery pack depends on number of factors such as; type of cell chemistry, form factor, pack architecture (modular or cell to pack) and most importantly the legislative requirements.
Never charge a primary (disposable lithium or alkaline) battery; store one-time use batteries separately. Charge or discharge the battery to approximately 50% of capacity before long-term storage. Use chargers or charging methods designed to charge in a safe manner cells or battery packs at the specified parameters.
