| 摘要 |
The invention relates to a method and a device (1) for charging a battery (4) of an electric or hybrid vehicle, comprising a battery (4) and a battery management system (5), wherein the battery (4) consists of a plurality of battery cells (BZ1-BZn) at least partially connected in series, wherein by means of a transducer the voltages (UBZ1-UBZn) of the series-connected battery cells (BZ1-BZn) are detected and are evaluated in an evaluation unit (7), wherein depending upon the detected voltages (UBZ1-UBZn) of the battery cells (BZ1-BZn) the battery management system (5) controls at least one power switch (8, 9) between the battery (4) and a charger inside or outside the vehicle, wherein the charge management system (2) is designed in such a way that a value for a maximum charging current (Iabs), at which the charge management system (2) limits a charge current, is stored, wherein the charge management system (2) is also designed in such a way that by means of a transmitted charging current (I) an actual charge quantity (Q) is determined and is compared with a stored value for a maximum charge quantity (Qmax), wherein the charge management system (2) interrupts a charging path when the actual charge quantity (Q) reaches the maximum charge quantity (Qmax). |
