Description

technical field [0001] The invention relates to the technical field of automatic detection of DC charging piles, in particular to a portable fault testing system for DC charging piles and a detection method thereof. Background technique [0002] New energy vehicles have the characteristics of low pollution, low economic cost, and high performance, and will become the mainstream of the future development of the automotive industry. The development of new energy vehicles promotes the development of its charging facilities. It is predicted that a large number of charging piles will be put into use in the future. Charging piles are further divided into DC charging piles and AC charging piles. Among them, DC charging piles have the advantages of high efficiency and fast charging, adapt to today's fast-paced life, gradually replace AC charging piles, and become the mainstream charging facilities in the future. [0003] Although the charging facility industry is developing rapidl...
