1. A vehicle comprising:
a battery including a plurality of cells;
a temperature sensor located at a surface of one of the cells to measure a surface temperature;
a motor; and
one or more controllers programmed to, responsive to data indicative of an internal cell temperature of one or more of the cells exceeding a threshold, decrease power output from the battery to the motor, wherein the data is based on the surface temperature and a cell heating power parameter derived from a plurality of parameters, including a current output by one or more of the cells, and via a delay timer and a filter having a first sampling rate less than a second sampling rate at which the current is measured.
