Electric vehicle charging power generation device and emergency dispatch vehicle having same

The present invention relates to a generator for charging an electric vehicle and an emergency dispatch vehicle having the same, and more particularly, to a generator for charging an electric vehicle immediately and an emergency dispatch vehicle for charging the electric vehicle.

In general, when the fuel of the vehicle runs out while driving, a small amount of gasoline or diesel is purchased by using a nearby gas station, and in the case of LPG, the vehicle is operated by emergency supplementation with butane gas. However, in the case of electric vehicles, emergency charging is impossible without electric vehicle charging equipment and high voltage electricity when the vehicle is discharged while driving. Therefore, the vehicle must be towed to the electric vehicle charging station.

In this regard, there is an emergency dispatch charging vehicle using an energy storage system (ESS), but in order to charge a discharged vehicle, it is necessary to charge its own internal battery for a long time. There is a problem that you can not move several times a day because the built-in battery must be charged for a long time at all times for one or two times of dispatch so that time is required for recharging after one dispatch.

In addition, in case of emergency vehicle's built-in battery which has to be equipped with expensive dedicated charging device to charge the built-in battery and continuously charge and discharge the battery, the life of the emergency battery is shortened rapidly and the battery can be used within 3 ~ 4 years. The replacement was not commercialized due to the high cost structure, which regularly incurs a battery repurchase cost. In this regard, as the prior art, there is a registered patent No. 10-0500972 "generator attached integrally to the vehicle", there was a problem that the efficiency of the generator is not high.
