A battery charger employs a temperature sensor and single chip microcomputer (SCM) programs for controlling and performs charging with a pulse current. The polarization occurred during battery charging can be eliminated and the charging voltage and current can be automatically regulated based on ambient temperature. An intelligent pulse temperature control charger has a casing and a charging circuit having a high voltage switch power supply circuit and a low voltage control circuit. In the low voltage control circuit, a SCM is employed for controlling, the SCM has three pins as input terminals connected to a temperature sampling circuit, charging voltage sampling circuit and charging current sampling circuit of the battery, respectively, and the SCM has two pins as output terminals, one connected via a photoelectric coupler with the high voltage switch power supply and the other connected with a dichromatic light emitting tube and a heat dissipation fan.
