METHOD FOR CHARGE EQUALIZATION IN A BATTERY SYSTEM AND BATTERY SYSTEM HAVING A CHARGE EQUALIZATION CIRCUIT

摘要

The invention relates to a method for charge equalization between two cells of a cell network of a battery system, and to a battery system having a charge equalization circuit and comprising two or more cells having a resting voltage. The charge equalization circuit feeds an intermediate energy store in a first state. In a second state of the charge equalization circuit, a cell is charged at a charging voltage, wherein the charging voltage is greater than any of the two cell resting voltages.
