Method for fully balanced charging of battery cells with charging circuit, involves conducting energy into battery cells, so that charge current flows into battery cell with deep voltage than into another battery cell with high voltage

摘要

The method involves feeding energy of a voltage source (1) into a magnetic circuit of a transformer (3) by shift operations a primary unit (2). Insulated gate bipolar transistor components (8, 9) are deactivated according to a controlled time in the primary unit. The energy stored in the magnetic circuit of the transformer is conducted into battery cells connected in series by a diode unit (4), so that charge current flows into one battery cell with deep voltage than into another battery cell with high voltage. The voltage source is connected with a primary winding (P) of the transformer. An independent claim is also included for a circuit device for fully balanced loading of battery cells with a charging circuit.
