Abstract:
PROBLEM TO BE SOLVED: To provide a power supply device capable of efficiently cooling a battery and a working machine including the same.SOLUTION: A power supply device 1 includes: a plurality of batteries 2; a blower 5 in which a blowing portion 5a for blowing out air is arranged on one side of batteries 2; and a housing 3 for storing the batteries in an internal space which is constituted by a plurality of wall surfaces including a first wall surface 31 provided on the other side opposite to the one side of the batteries 2 and a second wall surface 32 connected to the first wall surface 31 and extending from the first wall surface 31 to the blower 5 side. An air introduction passage 50 for introducing air into the batteries 2 is formed between the first wall surface 31 and the batteries 2. A flow passage 60 is formed between the second wall surface 32 and the batteries 2 for guiding the air blown from the blower 5 to the air introduction passage 50. A passage sectional area of at least a part of the air introduction passage 50 is larger than a passage sectional area of the flow passage 60.SELECTED DRAWING: Figure 2
