PROBLEM TO BE SOLVED: To provide a construction machine capable of making a use range of the charging rate of a power storage device suitable to a temperature and sufficiently utilizing the performance of the power storage device.SOLUTION: The construction machine comprises: an engine; a generator; a battery that is a power storage device; charging rate calculation means that calculates the charging rate of the battery; temperature measurement means; and use range setting means for setting the use range of the charging rate. The use range setting means sets the use range of the charging rate at a predetermined range when a battery temperature is a predetermined temperature and, when a battery temperature is lower than the predetermined temperature, sets the use range of the charging rate to be smaller than the predetermined range. |
