Abstract
An apparatus for controlling the charging voltage applied to a battery cell includes a printed circuit board having a flexible portion comprising a heat sensitive material which is wrapped around the battery cell for sensing the temperature of the battery cell during charging of the battery cell. Circuit means connected to said temperature battery apparatus disables the charging voltage upon the temperature of the battery cell reaching a predetermined level and generates a trickle charge in response to the disabling of the charging voltage.
