Abstract

The present invention provides a battery unit for a vehicle which can avoid the interference of electric wave generated to the outside and the inside of a battery shell due to the electric noise of acable. The battery unit for the vehicle (10) is provided with: a battery module (M) formed by stacking a plurality of battery cells; a battery case (11) that houses the battery module (M); a connectorsection (C) arranged in the battery case (11); and a cable (33) that electrically connects the connector section (C) and the battery module (M). The battery case (11) is provided with a metal frame beam (15) having a hollow section (25). The cable (33) is disposed in the hollow section (25) of the frame beam (15).

Description

technical field [0001] The present invention relates to a vehicle battery unit mounted on a vehicle. Background technique [0002] A battery unit mounted on a vehicle is provided with a cable that electrically connects a battery module formed by stacking a plurality of battery cells to a connector portion provided on the battery unit. A cable through which a relatively large current flows may cause radio wave interference to electronic devices arranged around the cable due to electrical noise, and therefore it is necessary to take measures to prevent radio wave interference. As a countermeasure against radio wave interference, for example, use of shielded electric wires is mentioned. [0003] However, since the shielded wire is expensive, the cost of the battery unit increases. In addition, as a countermeasure against radio wave interference of a battery cell, for example, a countermeasure described in Patent Document 1 is known (for example, Patent Document 1). [0004] ...
