Vehicle power supply device and method for producing vehicle power supply device

Abstract

A power supply device includes a battery block 2, a hollow exhaust duct 20 and an exterior case 30. The battery block 2 includes rectangular battery cells 1A that are arranged side by side and have gas relief ports 12 of gas relief valves 11. The gas relief ports 12 are aligned in substantially the same plane. The exhaust duct 20 extends along the gas relief ports 12, and exhausts gas relieved from the gas relief ports 12. The exterior case 30 accommodates the battery block 2 with the exhaust duct 2 arranged on the battery block 2. The exhaust duct 20 includes interlocking portions 40 that are arranged on different positions from a pair of guide portions 26, and protrude downward. The battery block 2 includes interlock reception portions 45 that interlock with the interlocking portions 40 and are arranged at positions corresponding to the interlocking portions 40.

Description

technical field [0001] The present invention mainly relates to a power supply device for a vehicle that supplies power to a motor that drives a hybrid vehicle, an electric vehicle, or the like, a vehicle equipped with the power supply device, and a method for manufacturing the power supply device for a vehicle, and particularly relates to discharging the battery to the outside through a discharge duct. A power supply device for a vehicle that discharges gas from an exhaust valve of a battery cell, a vehicle equipped with the same, and a method for manufacturing the power supply device for a vehicle. Background technique [0002] A battery system including a plurality of battery cells can be used for charging and discharging a large current like a power supply device of a hybrid vehicle because the battery cells can be connected in series to increase the output voltage. This battery system discharges a very large current when the vehicle is accelerating, and is charged with a...

Problems solved by technology

Therefore, in order to overcome the reaction force, it is necessary to increase the pressing force on the upper case, which makes the fixing work of the upper case complicated.

In addition, since the seal is located inside the upper case, it cannot be confirmed from the outside even if the seal is misaligned or unintended engagement occurs due to the fitting operation of the case as the upper case.

In this way, regarding the above-mentioned fixing structure, there is a problem that the discharge duct and the exhaust port 95 cannot be easily and reliably connected in an airtight state.
