Patent attributes
In the present battery apparatus for a vehicle, a temperature detecting plate 30 is fixed outside a casing 10 accommodating a plurality of secondary batteries 20. The casing 10 is provided with ventilation holes 15 for cooling the secondary batteries 20 between the secondary batteries 20 and the temperature detecting plate 30. The temperature detecting plate 30 fixes temperature sensors 50 on an insulation substrate 31. The insulation substrate 31 has air holes 33 communicated with the ventilation holes 15 of the casing 10, and a communicating portion 34 is provided between the air holes 33. The temperature sensor 50 is fixed to the communicating portion 34, and thereby the temperature sensor 50 is located so as to have access to a surface of the secondary battery 20 via the ventilation hole 15.
