The BMS uses current data to protect the battery from over-current conditions, which can lead to overheating and potential damage. Additionally, current monitoring supports accurate energy accounting and helps in diagnosing potential issues.

2. Protection

* Over-Voltage Protection

Over-voltage protection safeguards the battery from excessive voltage levels that can cause damage to the cells. The BMS monitors the voltage of each cell and the overall pack and takes action if the voltage exceeds safe thresholds. This may involve disconnecting the battery from the charging source or triggering an alarm to alert users. Over-voltage protection is crucial for preventing cell degradation and ensuring the battery’s safety and longevity.

* Under-Voltage Protection

Under-voltage protection prevents the battery from being discharged below a safe voltage level. Excessive discharge can lead to cell damage, reduced capacity, and decreased overall performance. The BMS monitors cell voltages and disconnects the load or triggers an alert if the voltage drops below a predetermined threshold. This function helps preserve the health and lifespan of the battery by avoiding deep discharge conditions.

* Over-Temperature Protection

Over-temperature protection ensures the battery does not exceed safe operating temperatures. High temperatures can lead to thermal runaway, where the battery rapidly heats up, potentially causing fires or explosions. The BMS monitors cell temperatures and activates cooling systems, reduces current flow, or shuts down the battery pack if temperatures rise above safe limits. This protection mechanism is essential for maintaining battery safety and performance.

* Over-Current Protection

Over-current protection guards against excessive current flow that can damage the battery cells and circuitry. The BMS monitors the current and takes action, such as reducing the load or disconnecting the battery, if the current exceeds safe levels. Over-current protection helps prevent overheating, cell damage, and potential safety hazards, ensuring the battery operates within its designed current limits.

3. Balancing

* Passive Balancing

Passive balancing involves dissipating excess energy from higher-charged cells as heat to equalize the charge across all cells in the battery pack. This method uses resistors to discharge the higher-charged cells, bringing them into balance with lower-charged cells. While passive balancing is relatively simple and cost-effective, it is less efficient than active balancing as it wastes energy as heat.

* Active Balancing

Active balancing redistributes energy from higher-charged cells to lower-charged ones, achieving charge equalization without significant energy loss. This method uses inductors, capacitors, or transformers to transfer energy between cells. Active balancing is more efficient than passive balancing and helps extend the battery pack’s overall efficiency and lifespan by ensuring all cells are equally charged.

4. State Estimation
