Why would a well-funded traditional enterprise devote itself to the new energy industry? Because of the frequent earthquakes in Sichuan, all the people living here are aware of the importance of protecting the environment. So our boss decided to devote himself to protecting the environment, in 2016 founded Green Science, hired a professional R & D team deeply in the charging pile industry, reduce carbon emissions, air pollution.

In the past 9 years, our company has cooperated with the government and state-owned enterprises to open up domestic trade while vigorously developing foreign trade with the help of major cross-border e-commerce platforms and exhibitions. Up to now, hundreds of charging station projects have been successfully established in China, and the products sold abroad cover 60% of countries in the world.

Factory Introduction

Our Team

DC Charging Station Assembly Area

Our Team

AC Charger Assembly Area

We are manufacturering the DC Charging Station for our local market, the products cover 30kw, 60kw, 80kw, 100kw, 120kw, 160kw, 240kw, 360kw. We are providing the complete charging solutions starting from the location consulting, equipment layout guide, installation guide, operation guide and routine maintenance service . 

These area is for DC charging station assembly , each row is one model and is a production line. We ensure the right components appear in the right place. 

Our team is a young team, the average age is 25-26 years old. The experienced engineers are coming from Midea, MG,   University of Electronic Science and Technology of China.  And the production management team are coming from Foxconn. They are a group of people who have passion, dream and resposibility.

they have a strong sence of orders and procedures to ensure the production to strictly follow the standard and qualified. 

We are producing three standards of AC EV charger: GB/T, IEC Type 2, SAE Type 1. They have different standard of components, so the biggest risk is mixing the components when three different orders are manufacturing. Functiomaly, the charger can work, but we need to make each charger qualified.

We splitted the production line into three different assembly lines: GB/T AC Charger assembly line, IEC Type 2 AC Charger assembly line, SAE Type 1 AC Charger assembly line. So the right components only will be at the right area.

AC EV Charger Testing Equipment

Raw Material Inspection

R&D Laboratory

This is our automatical testing and aging equipment, it's simulating the standard charging performance at the max current and voltage to check the PCBs and all the wiring, relays to reach the balance to work and charge.  We also have another automatical test equipment to test all the electrical key feature such as security test, high-voltage insulation test, over current test, over current test, leackage test, ground faut test, etc. 

This part belongs to IQC procedures, all the raw materials and components will be inspected and checked. some qualified supplier will be spot check, and new supplier will be full check. For the PCBs, we are doing the full check. And for the performance test and aging test are also 100% full test to ensure each chargers are be tested and inspected before delivery.

Our office and factory are 30km far away. Normally our engineer team are working in office in the city. Our factory are only for daily production, testing and shipping. For the research and development testing, they w will finish here. All the experiment and the new function will be tested here. Such as Dynamic load balance function, solar charging function, and other new technologys.

    The contact was friendly and helpful. The wall box arrived in top condition. Inside, however, a communication cable had come loose. The problem was solved together with the help of the technician. The app also works so far. I am completely satisfied.

    I havent installed it yet but it looks definitely a very high quality. Costumer support is excellent. It also comes with a 1 year warranty for all their products. Do not overpay the dealer wall charger does not worth it. Many are so dumb not even close to this one in terms of quality and app control. I will definitely order more for my friends as well.
