Solar container lithium battery pack balancing error

What happens if a battery pack is unbalanced?

An unbalanced pack is more likely to overheat, which can lead to thermal runaway—a situation where rising temperatures inside the battery pack create a feedback loop, leading to uncontrollable heat buildup and potentially resulting in a fire or explosion. Proper balancing helps prevent this by ensuring all cells are charged and discharged evenly.

What causes battery balancing problems?

Imbalance in battery packs arises from factors such as uneven cell aging, self-discharge variations, faulty balancing systems, or temperature inconsistencies. Repairable: Can often be resolved via the BMS (Battery Management System) balancing function or manual charge/discharge adjustments.

What is lithium battery imbalancing?

Lithium battery cells imbalancing occurs when individual cells in a battery pack exhibit varying states of charge, capacity, or voltage. This discrepancy can compromise the battery’s overall performance and safety. For instance: Variations in capacity and impedance create uneven cell currents, generating heat and temperature gradients.

Why should you use a battery balancing system (BMS)?

Balancing batteries might seem like an extra chore, but it’s vital for maintaining the health, safety, and performance of your power systems. By using a BMS, following manual balancing steps when needed, and maintaining good charging habits, you can dramatically extend the life of your batteries.
