Monitoring of the surface temperature of battery cell is an important means of performance evaluation. Due to increases of cell's internal resistance, the surface temperature will be higher than other normal cells. Experience shows that when resistance increases by 25%, which is serious dysfunctional, the cell's surface temperature was higher, but the floating charge voltage is still maintained at the normal value. Thus, by monitoring the surface temperature of the cell, dysfunctional ones can be detected earlier.

Battery temperature detection  is ideal for important and critical sites.
