Tracking voltage, current, temperature, and overall pack health.

Individual cells in a series pack inherently drift in capacity and state of charge over time. battery management systems davide andrea pdf link

Third, addresses the fact that no two cells are identical. Over many cycles, small differences in self-discharge or internal resistance cause cell voltages to diverge. Without balancing, some cells would overcharge while others remain undercharged, rapidly destroying the pack. Andrea describes two balancing methods: passive balancing (dissipating excess energy as heat through resistors) and active balancing (shuttling energy from high-voltage cells to low-voltage cells, which is more efficient but complex). which is more efficient but complex).
