Background
In recent years, in response to global warming and climate change caused by greenhouse gas emissions，many 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.
Project Overview
The company is a charging pile manufacturer located in South Korea， using our DC energy meter DJSF1352-RN to match their DC charging pile. After using it for a period of time, they’re very satisfied with the quality of our products.
