The invention relates to a method for detecting an unstable state of a vehicle battery, in particular of at least one power battery (16) of an electrically driven vehicle (10). At least one power battery (16) is monitored by a battery monitoring unit (20). In the event of a critical, unstable state, the battery monitoring unit (20) notifies the vehicle-side charging communication unit (22). The vehicle-side charging communication unit (22) transmits information about the degree of criticality of the current state of the vehicle (10) to the charging point-side charging communication unit (24) via the communication interface (32). In a coordinator (30) comprising an emergency measure register (34), an introduction of a measure for reducing risk and/or danger is requested. The invention further relates to the use of the method for detecting a critical and/or unstable state of at least one power battery (16) of an electrically driven vehicle (10). 本发明涉及一种用于探测车辆电池的、特别是电气驱动的车辆(10)的至少一个动力电池(16)的不稳定状态的方法。由电池监控单元(20)监
