| 摘要 |
The invention relates to a method for operating a battery system (10) for supplying a load with electrical power, comprising at least one electronic switching unit (14, 16) arranged between a battery and the load, wherein at least one electronic switching unit (14, 16) has a main current path (22), which in particular can be opened by means of a main switch (24), and wherein the electronic switching unit (14, 16) has a secondary current path (26), which can be opened and which is arranged in parallel with the main current path (22), in which secondary current path a secondary resistor (29) and possibly a secondary switch (28) are arranged, comprising the following steps: a) supplying the load with electrical power, wherein the main current path (22) and the secondary current path (26) are closed; b) detecting a safety-critical state; c) opening the main current path (22). The method described above is based substantially on defined control of an electrical switching unit (14, 16), whereby significantly increased safety during operation of a battery system (10) and furthermore especially economical operation of the battery system (10) can be enabled. The invention further relates to a battery system (10) designed to perform such a method. |
