Charging Pile Energy Management System Solution

Overview

In recent years, in response to global warming and climate change caused by greenhouse gas emissions，major countries have focused on promoting electric vehicles to replace traditional fuel vehicles. And the construction of charging piles is very important in the promotion of new energy vehicles. Therefore, a large number of charging pile projects have emerged around the world.

Single phase and three phase AC, DC energy meters complies with the corresponding IEC standards and can be used in all kinds of AC and DC charging piles to realize charging energy measurement, and can transmit electrical parameters in real time through communication.
