Electric warm current boosts 4-day charging pile service in Gaochun

Mr Li, a resident of Hubin Yipin Community in Nanjing's Gaochun district, applied for a home charging pile via the State Grid Online app. The whole procedure from application to power connection was finished in four working days, reducing the service cycle by over 60 percent.

This remarkable level of efficiency comes from two innovations pioneered by State Grid Nanjing Power Supply Company, the first of which was in Jiangsu province: a batch consent certificate system for residential charging piles and an AI automatic power supply scheme generation.

Booming new energy vehicle ownership has spurred demand for household charging piles. Previously, applicants had to separately obtain an installation consent certificate from their property management before applying to power departments.

Many residents faced problems including uncooperative property staff, complicated coordination, repeated errands and lengthy waiting periods.

To address this bottleneck, in October 2025 the company partnered with the local government to launch the province's first batch consent mechanism via administrative guidance.

Properties conduct the unified verification of private parking spaces and issue bulk certificates at once, so residents no longer need to apply for individual permits every time they install charging piles.

As the community property manager explained, applicants only need documents confirming their identity, parking space ownership and vehicle purchase to submit applications directly to power suppliers.

The batch certificate system eliminates the resident-property communication barrier, while AI technology further slashes processing time.

Supported by the Guangming large model, the system auto-fetches substation capacity data, evaluates grid load and generates the best power supply plan within minutes. In contrast, traditional manual site inspections and cross-department drafting used to take one or two working days.

The combined strengths of batch certification and instant AI schemes simplify charging pile installation from multiple visits and days of waiting and online application and connection within three days.

Since the start of this year, 51 applications have been completed through this model, with the average service time reduced by over 40 percent.

As of July 31, 73 local residential compounds had secured batch certificates, covering nearly all qualified gated communities with private parking spaces. The practice embodies the tangible public benefits of the Electric Warm Current campaign supporting green transport.

According to State Grid Nanjing Power, the company is now coordinating with subdistrict and local government authorities to reach out to the remaining uncovered communities on a one-by-one basis, and to expedite the parking space survey and batch certificate signing process.

The goal is to achieve full coverage across the entire district by early September, providing a replicable local model for improving the charging facility service system in urban residential areas.
