Battery Management Systems
What are they?
Battery management systems or BMS are an integral part of any battery system. They control how the battery functions and how well they perform under various conditions.
Why do we need them?
Batteries have complex chemistries which need to be monitored and maintained. This is critical that these battery systems stay within certain limits, to ensure they are not damaged or destroyed. In addition a good BMS will extend the life of you batteries by reducing oxidation and plate damage. In the long run they will always prove value for money.
How do they work?
BMS measure a range of parameters, namely voltage, current, temperature and sometimes specific gravity. They use various probes, meters and sensors to detect the conditions affecting the battery. These can include high ambient temperature, excessive current draw and over voltage. These measurements are further recorded and computed to determine state of charge and battery health providing further insight into the batteries performance.
