Functional Safety of Battery Management Systems (BMS)
A Battery Management System (BMS) is essential for the functional safety of a battery, particularly for lithium-ion batteries. It monitors and controls various battery parameters such as voltage, current, and temperature to ensure the battery operates within safe limits and is protected against overcharge, deep discharge, overheating, and other hazardous conditions. Functional safety in the BMS is crucial to minimize risks and increase the reliability and lifespan of the battery.

Cell Performance (ageing) testing
Battery cell aging is necessary to determine the lifespan and performance of the battery. This process involves exposing the battery to different environmental and other factors, like temperature and cycling. This simulates the effects of long-term use.
We can identify potential safety hazards by subjecting battery cells to certain conditions. Additionally, we can evaluate the impact of aging on battery capacity, internal resistance, and other critical parameters.
Our laboratory can provide numerous channels with up to 5 V. Each channel has a maximum current of 50 A. We can also apply 1000 A in parallel. Furthermore, we can apply different temperature profiles for ambient conditions.
We record and measure data on capacity and internal resistance. This provides a comprehensive evaluation of the battery's performance and aging characteristics.
The data collected from this process is then used to develop detailed models of the battery’s performance and aging characteristics. This information is used for multiple purposes. It helps inform future design decisions, optimize battery performance, and guarantee safety and reliability for the intended application.
Our laboratory is equipped with advanced testing capabilities. We can simulate various real-world scenarios, such as high temperature and repeated discharging and recharging. We can also simulate extreme conditions. This allows us to evaluate the battery’s performance under a wide range of environmental and other conditions.
