Balancing of electrical voltages on the terminals of serially mounted electrical cells

摘要

The device (DISP) has a deliverance unit (DELIV1) for delivering an electrical voltage (V1) equal to half of sum of electrical voltages on terminals of a group of three electric cells. A deliverance unit (DELIV2) delivers an electrical voltage (V2) equal to sum of an electrical voltage on terminals of one of three electric cells that is placed at an end of the group, and half of an electrical voltage on terminals of the electric cell placed at the middle of the group. A comparator (COMP) compares the delivered electrical voltages and includes an electrical voltage amplifier. Independent claims are also included for the following: (1) an autonomous system for automatically balancing electrical voltages on terminals of electric cells of an electric battery, comprising electric cells (2) a method for balancing electrical voltages on terminals of electric cells of a group of three electric cells placed in a series.
