Mobile charging station

Abstract

The present invention provides a mobile charging station, comprising a mobile energy storage device, a power conversion device, a direct current charging device, a cable winch and a system control device that are disposed on a car body. The system control device controls the mobile energy storage device, the power conversion device and the direct current charging device. The power conversion device rectifies electric energy obtained from a power grid and charges the mobile energy storage device; performs inversion on electric energy output by the mobile energy storage device, and performs emergency power supplement for an electrical load on a power grid side; and performs inversion on electric energy output by the mobile energy storage device and provides inverted electric energy to the direct current charging device, and the direct current charging device performs rectification and transformation on the inverted electric energy and then charges a to-be-rescued electromobile. The cablewinch is used for placing a charging cable of the direct current charging device. According to the mobile charging station, timely power protection can be performed on an electrical load in an important department and a key position when a power failure crisis occurs on a power grid side, and further, a problem caused by low power of the electromobile in an actual driving process can be resolved.

Description

technical field [0001] The invention relates to the technical field of energy storage system application and charging service, in particular to a mobile charging station. Background technique [0002] With the rapid development of society, many important facilities have higher and higher requirements for power supply reliability. Once the power supply system fails suddenly and the power supply is interrupted, it will cause heavy losses. Therefore, it is necessary to ensure emergency protection of power supply, that is, power supply When the line is out of power, the backup power supply is switched to supply power to the load. At present, the widely used emergency power supply systems mostly use diesel generators as the driving device to realize emergency power protection of power supply lines, while emergency power protection systems for diesel generators can only provide emergency power protection for fixed equipment in fixed areas. If emergency power protection is needed,...
