Abstract:
A vehicle includes a system operating a method of controlling a temperature at a battery cell of the vehicle. The system includes the battery cell, a temperature sensor and a processor. The battery cell has a tab for flow of current to and from the battery cell. The temperature sensor is configured to measure a cell temperature of the battery cell at a location away from the tab. The processor is configured to predict a tab temperature from the cell temperature, and control a power supplied to a load from the battery cell based on the tab temperature.
