PROBLEM TO BE SOLVED: To obtain a battery charger for an industrial electric vehicle, which has a temperature measuring function that is hardly affected by various kinds of disturbance factors, such as the vehicle motor, controller element, the direct sun insulation, a battery itself, etc., can make the charging time of a battery appropriate, can make the attaching portion of a temperature sensor arbitrarily selectable. SOLUTION: A battery charger is provided with a timer 10, having a time setting function by perceiving that there is a possibility of the outside air temperature and the temperature of an electric industrial vehicle itself being stabilized in a certain specific time zone in a day and it is possible to more accurately measure the outside air temperature and to reflect the measured temperature in the charging time of a battery 24. The battery charger sets outside air temperature measuring time at a prescribed time (for example, 6 o'clock in the morning) at which the temperature of the vehicle and outside air are stabilized by means of the timer 10, and at the same time, controls a temperature sensor 13 to measure the outside temperature at the outside air measuring time by means of a control means 7.
