The core power conversion unit that supports ultra-fast charging technology is mostly used in scenarios such as new energy vehicle supercharging piles, which can efficiently convert grid energy into high-power DC power adapted to power batteries, and its design and performance directly determine the charging efficiency and stability of supercharging equipment. The energy replenishment efficiency is extreme, close to the same speed of oil and electricity; Strong adaptability and compatible with many types of models; Efficient operation and low losses; low operation and maintenance cost and strong practicability; More reliable operation and better experience.
