Description

Electric Vehicle Emergency Power Supply Apparatus The present invention relates to an electric vehicle emergency power supply device. Recently, interest in electric vehicles (EVs) as a replacement for fossil fuels such as gasoline and diesel has surged in the automotive industry, and consumer sales of EVs are also steadily increasing. Generally, an electric vehicle refers to a vehicle that uses batteries and motors as power sources instead of an engine. EVs charge their internally mounted batteries via a charging system while parked and drive using the electrical energy stored in the batteries. The majority of electric vehicles (EVs) are charged via fixed charging stands. Currently installed EV charging facilities primarily utilize a method where fixed chargers are installed within parking spaces, and these areas are designated as EV-only zones. While this fixed charging method does not pose a significant problem during the initial stages of EV adoption, it may lead to difficulties in efficiently utilizing parking spaces as the number of EVs increases. Particularly in densely populated environments like urban areas, where EV-only zones must always be kept empty, there is a high likelihood that parking space shortages will worsen. To solve these problems, electric vehicle charging methods utilizing portable batteries are being researched. Meanwhile, in spaces where many vehicles are parked, such as large shopping malls and apartment complexes, parking spaces for electric vehicles and conventional vehicles must be separated, making it difficult to utilize parking spaces efficiently. Although electric vehicle charging infrastructure is gradually expanding, the actual commercialization rate is not increasing as rapidly as expected due to a shortage of charging stations. For example, the combined fuel efficiency of 1-ton electric vehicles currently on the market, such as Hyundai Motor’s Porter 2 EV or Kia Motor’s Bongo 3 EV, is only about 211 km. In particular, during the winter, battery performance deteriorates, and as power from the main high-voltage battery is used for heating, the driving range drops to about 150 km. This problem increases anxiety among electric vehicle drivers and is one of the significant factors hindering the practical convenience and safety of electric vehicles. Consequently, there is a need to develop a portable charging system capable of reliably supplying power to electric vehicles in any emergency situation.
