Abstract
A computer system is provided. The computer system includes a processor device configured to determine a requested take-off of a parked electric vehicle; determine a battery temperature of at least one battery cell of the electric vehicle; determine an ambient temperature of the electric vehicle; determine a thermal activity state of at least one battery cell as the difference between the battery temperature and the ambient temperature; and prevent the requested take-off when the thermal activity state is above a predetermined thermal activity state threshold.
Claims16
A computer system comprising a processor device configured to:
- determining a requested take-off of a parked electric vehicle;
- determining a battery temperature of at least one battery cell of the electric vehicle;
- determining an ambient temperature of the electric vehicle;
- determining a thermal activity state of at least one battery cell as the difference between the battery temperature and the ambient temperature;
- and
- preventing the requested take-off when the thermal activity state is above a predetermined thermal activity state threshold.
A computer-implemented method, comprising:
- determining, by a processor device of a computer system, a requested take-off of a parked electric vehicle;
- determining, by the processor device, a battery temperature of at least one battery cell of the electric vehicle;
- determining, by the processor device, an ambient temperature of the electric vehicle;
- determining, by the processor device, a thermal activity state of at least one battery cell as the difference between the battery temperature and the ambient temperature;
- and
- preventing, by the processor device, the requested take-off when the thermal activity state is above a predetermined thermal activity state threshold.
