In general, battery balancing methods can be categorized into the following types: Passive balancing dissipates excess energy from higher-charged cells as heat, while active balancing employs a switch matrix and transformer to transfer energy between individual cells.
How much balancing voltage should a lithium ion battery have?
Start balancing voltage should be set around 5-10% of the maximum state of charge, with a recommended maximum voltage difference of 10mV between cells for most lithium-ion chemistries. The minimum balancing voltage setting must be below the settling voltage to allow effective balancing.
What happens if a battery is not balancing?
During discharge, it's limited to 425 kWh (85%), resulting in a 15% capacity loss. Without balancing, this discrepancy grows, locking away more energy and accelerating cell degradation. In parallel configurations, voltage mismatches cause circulating currents, forcing clusters with lower resistance to charge or discharge faster.
