To safely utilize lithium-ion or lithium polymer batteries, they must be paired with protection circuitry capable of keeping them within their specified operating range.
Lithium batteries are characterized by high energy and power density. Mishandling lithium batteries can lead to serious failures like thermal runaway, lithium plating, electrode decomposition, etc. Consequently, such batteries require special care in stressful conditions such as overcharge, undercharge, short circuits, overheat, etc.
The most important faults that the batteries must be protected from are overvoltage, overcurrent, and over temperature conditions as these can place the batteries in a dangerously unstable state. The same is true for undervoltage conditions, though to a lesser extent.
Inrush currents arise during the turn on, mainly when the battery is first connected to the load. The inrush currents can get high enough to either destroy the protection circuit or to blow of the protection fuse. A load pre-charge circuit would limit the inrush current during the turn on phase and protect both the battery and the load.
For that, Infineon ofers a wide range of battery protection solutions that, under stressful conditions, increase lifetime and eficiency of lithium batteries. The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating.
The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on.
