Energy storage charging pile has high instantaneous starting current

Methods to reduce the starting current of an induction motor

An inrush current is produced when an electric load is turned on. For an induction motor this current can reach 5-10 times the full-load current. This transient current can cause issues in large machines attached to weak grid connections. To protect the grid connection this paper explores ways that the starting current can be reduced. Standard starting …
