Industrial Park Charging Pile Project — 210 Vertical AC Piles Build a Green Energy Network

With the in-depth advancement of the "Dual Carbon" strategy, industrial parks across the country are accelerating their transformation toward green, low-carbon and intelligent development. In industrial scenarios, the charging demand for employees’ commuter vehicles, logistics shuttle vehicles and visitors’ new energy vehicles keeps growing. The shortage of charging infrastructure has become an underlying weakness affecting employee satisfaction and park investment attraction.

A large-scale industrial park in Changzhou took on this challenge by deploying 210 Green GL-1016 vertical AC charging piles at 10 parking sites, each with a power of 22kW. It has built a convenient park-wide charging network, effectively solving the charging difficulties of thousands of employees and settled enterprises.

Covering a vast area and located far from the city center, the park sees most employees relying on self-driving commutes. In recent years, with the rapid penetration of new energy vehicles, the proportion of employees driving EVs in the park has risen from less than 5% to nearly 30%.

However, the original park only had a few scattered slow-charging sockets, which were seriously insufficient in quantity, low in power and high in failure rate. Employees often had to arrive at the company one hour in advance to "grab a charging pile", or detour to public fast-charging stations after work, greatly reducing commuting efficiency.

To make matters worse, the park hosts multiple logistics enterprises, and new energy light trucks require daytime power supplementation. The outdated charging facilities failed to meet the long-range energy supply needs of logistics vehicles, driving up corporate operating costs. After comprehensive evaluation, the park management adopted a one-time overall plan with phased implementation for large-scale charging infrastructure, and finally selected the Green GL-1016 vertical AC charging pile as the core equipment.

The Green GL-1016 vertical AC charging pile is specially designed for outdoor and semi-outdoor public parking scenarios. Compared with the 11kW piles commonly used in commercial buildings, the 22kW model delivers nearly double the charging speed.

Taking mainstream EVs with a 60kWh battery capacity as an example, a 22kW pile can supply about 22 kWh of electricity per hour, adding a cruising range of approximately 130–150 km. With an average parking duration of around 8 hours for park employees, it fully realizes full charge after work, and can efficiently serve multiple vehicles in rotation.

The project selected 1 prime parking locations covering major factory buildings, office buildings, staff dormitories and logistics loading/unloading areas. A total of 210 charging piles were arranged at each site according to parking space quantity and power capacity.

All piles adopt a vertical design with a height of about 1.4 meters and a small footprint. With an IP54 dustproof and waterproof rating, they adapt to the park’s outdoor environment characterized by heavy dust, large temperature differences and occasional rain and snow. The 5-meter charging cable easily reaches the charging ports of ordinary parking spaces and large vehicles.

In terms of power supporting facilities, the park’s original distribution room was expanded and renovated, and an intelligent load distribution system was introduced. If all 210 units of 22kW piles run at full load simultaneously, the total power would reach 4620kW, posing a huge impact on the power grid.

Green’s technical team adopted grouped rotating charging, dynamic power regulation and peak-valley time management strategies. Without compromising user experience, the actual maximum simultaneous operating power is controlled within 3000kW, realizing peak staggering with the park’s production power consumption.

In actual use, employees only need to scan the QR code on the charging pile with a mobile phone to start the charging process. The system automatically identifies the vehicle, displays real-time charging status, cuts off power and settles fees automatically when fully charged, with no manual intervention required.

The ultra-low operation threshold allows both experienced EV users and new beginners to complete the whole process within tens of seconds.

For park management, daily operation and maintenance of charging piles used to be a major concern. Equipped with built-in IoT modules, Green charging piles support real-time monitoring via the cloud platform for operating status, charging power, accumulated electricity consumption and fault alarms.

In case of equipment failure or offline status, the system automatically pushes notifications. The maintenance team can conduct remote preliminary diagnosis and accurate on-site repair, greatly improving fault response efficiency and reducing manual inspection costs.
