   - cell-level monitoring and cutoff for overvoltage or undervoltage; these are intended to maintain balance between cells of fast, high-current charging, as found in electric vehicles (EVs).     - cell-level monitoring and cutoff for overvoltage or undervoltage; these are intended to maintain balance between cells of fast, high-current charging, as found in electric vehicles (EVs).
