Data is sent to a BMS Master Controller, which aggregates and analyzes the information. Battery Management Unit (BMU): The Battery Management Unit (BMU) is a key component in a Battery Management System (BMS) responsible for monitoring and measuring critical parameters of the entire battery pack or its individual cells.
A BMS prevents overheating, short circuits, and thermal runaway, which can cause battery fires. 2. Longer Battery Life ⏳ A well-optimised BMS can extend lithium battery lifespan from 3-5 years (without a BMS) to 10-15 years by preventing deep discharges and overcharging.
Each cell in an EV battery has a specific voltage range within which it operates safely. The BMS continuously monitors the voltage of each cell to prevent overvoltage (which can damage the cells) and undervoltage (which can lead to capacity loss). By ensuring cells stay within their optimal voltage ranges, the BMS maximizes battery life. 2.
Cell balancing: Over time, the cells in a battery pack can become unbalanced, with some cells having higher or lower charge levels than others. A BMS can balance the cells by ensuring each cell is charged and discharged evenly, which helps maximize the battery run time.
