What is a battery management system (BMS)?

In the realm of modern battery technology, ensuring the safety and efficiency of batteries is crucial. This is where the Battery Management System (BMS) comes into play. A BMS is a sophisticated electronic system that monitors and manages the performance of batteries, providing several essential protections to enhance their safety and longevity.

What is a battery management system?

In conclusion, the Battery Management System is an indispensable component in modern battery technology. By providing essential protections and managing various aspects of battery performance, a BMS ensures that your battery remains safe, efficient, and reliable.

Why are thermistors used in BMS?

Thermistors have been widely used in BMS due to their versatility, low cost, and straightforward implementation. A voltage divider is commonly used to bias the thermistor. The voltage read across the thermistor is then converted to a temperature reading by the MCU/MPU to actively monitor the battery cells.

How does BMS detect battery overvoltage & undervoltage?

BMS detects battery over-voltage (OV) and under-voltage (UV) conditions. If the battery voltage exceeds or drops below the respectiv OV or UV threshold (BATTERY_OV or BATTERY_UV), OVP or UVP is triggered. The system t iggers a fault reaction and opens the protections to rea
