Description

Power distribution device and EV special vehicle having the same {POWER DISTRIBUTION DEVICE AND ELECTRIC SPECIAL VEHICLE HAVING THE SAME}

The present invention relates to a power distribution device and a specially equipped EV vehicle having the same, and more particularly, to a power distribution device configured to distribute power provided from a high-voltage battery pack to an electric vehicle and a specially equipped vehicle, and to a specially equipped EV vehicle having the same.

In general, each local government or road management agency performs an operation to keep the road surface clean by removing foreign substances accumulated on the road surface from time to time with respect to the road that has already been constructed and used.

Road cleaning work has a large cleaning area, so when it is dependent on manpower, efficiency is lowered, and the risk of accidents is high because the work is performed while vehicles are driving nearby. Therefore, road cleaning is usually performed using a road sweeper.

The road sweeper forms a combination of a driving vehicle unit and a cleaning vehicle unit. Here, the driving vehicle part is a vehicle part for moving the road sweeper to a required place, and the cleaning vehicle part is a vehicle part coupled to the rear side of the driving vehicle part and configured to substantially clean the road surface.

For example, in the case of a road sweeper using fossil fuel, each engine is provided in the traveling vehicle unit and the cleaning vehicle unit. Specifically, the engine provided in the driving vehicle unit provides power for driving the road sweeper, and the auxiliary engine provided in the cleaning vehicle unit provides power to the blowing force generating unit for suctioning foreign substances from the road surface. Such a conventional road sweeper has a problem in that the device structure of the road sweeper is complicated because each engine must be provided in the driving vehicle unit and the cleaning vehicle unit.

Recently, road sweepers that operate with electric energy instead of fossil fuels are being developed. In such an electric type road sweeper, batteries are provided in a driving vehicle unit and a cleaning vehicle unit, respectively, and the road sweeper is operated through electric energy provided from the battery. However, although the overall device structure of this electric type road sweeper is simpler than that of a conventional road sweeper using fossil fuel, it is still difficult to manage the battery because the driving vehicle part and the cleaning vehicle part must have separate batteries. .

Therefore, various research and development on special EV vehicles such as road sweepers and water cannons having simpler structures are required.
