Problems solved by technology

At the same time, there is a problem that cannot be ignored: the electric vehicle will not be able to continue driving because the electric energy stored in the on-board power battery is exhausted because it does not reach the charging station.
[0004] Through the research on the existing technology, the inventor found that: from the trailer to the scene, then fix the electric vehicle, and then tow it back to the charging station. Therefore, it takes a lot of time and costs are high

Abstract

The embodiment of the invention discloses an emergency charging vehicle and a charging system. The emergency charging vehicle comprises an AC / DC charger, a battery pack and a DC / DC charger, wherein the AC / DC charger is used for converting AC electric energy in a power grid into DC electric energy to be stored in the battery pack; the battery pack is used for storing electric energy; and the DC / DC charger is used for converting the electric energy stored in the battery pack into DC electric energy and charging the battery pack of an electric vehicle. In the technical scheme provided by the embodiment of the invention, the AC / DC charger, the battery pack and the DC / DC charger are arranged in the emergency charging vehicle, therefore, the electric energy can be supplied to the electric vehicle by driving the emergency charging vehicle to an electric vehicle site without dragging the electric vehicle to a charging station through a trailer when the electric vehicle can not move forwards due to run out of electric energy. Compared with the prior art, the scheme is timely and convenient and has lower cost.

Description

technical field [0001] The invention relates to the field of vehicles, and more specifically relates to an emergency charging vehicle and a charging system. Background technique [0002] Since the automobile was born in 1886, after more than 100 years of development, it has become the main means of transportation used in people's daily work and life. At present, the fuel of traditional fuel vehicles mainly comes from petroleum, but the shortage of petroleum and the environmental pollution caused by the exhaust of fuel vehicles have seriously restricted the development of fuel vehicles. As a green transportation tool, electric vehicles will bring great changes to human society in the 21st century. First, the energy saving effect is remarkable, and the comprehensive utilization efficiency of energy is greatly improved. The energy consumption of electric vehicles is 40% lower than that of traditional vehicles, and the cost of energy consumption per kilometer is reduced. It is ...
