METHOD FOR DETECTING AN UNSTABLE STATE OF A VEHICLE BATTERY

The invention relates to a method for detecting an unstable state of a vehicle battery, in particular at least of a traction battery (16) of an electrically powered vehicle (10). At least one traction battery (16) is monitored by a battery monitoring unit (20). In the event that a critical, unstable...

Beschreibung
Zusammenfassung:	The invention relates to a method for detecting an unstable state of a vehicle battery, in particular at least of a traction battery (16) of an electrically powered vehicle (10). At least one traction battery (16) is monitored by a battery monitoring unit (20). In the event that a critical, unstable state occurs, the battery monitoring unit (20) informs a charging communication unit (22) installed on the vehicle. The charging communication unit (22) on the vehicle provides information on the criticality of the current state of the vehicle (10), via a communication interface (32), to a charging communication unit (24) installed on a charging location. In a coordinator (30), which comprises an emergency measure register (34), initiation of measures to reduce the 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 traction battery (16) of an electrically powered vehicle (10).
