200kWh–140kW Energy Storage Charging Station After-Sales Support Project in Europe

Background & Challenge

A commercial customer in Europe purchased 5 units of 200kWh–140kW energy storage EV charging stations for local commercial charging operations.

As the equipment was deployed in daily operation, the customer placed significant importance on long-term system stability and reliable international after-sales support. Fast technical response and overseas maintenance capability were critical factors for ensuring uninterrupted charging service.

The Solution

Hefei KED Charging Technology Co., Ltd. supplied 5 units of 200kWh–140kW energy storage charging stations and continued providing comprehensive technical support after deployment.

During a local industry exhibition in Europe attended by the KED team, the engineers also arranged an on-site inspection and maintenance visit for the customer’s charging equipment. The technical team carefully checked the operating condition of all systems and confirmed that the equipment was functioning normally.

In addition to regular support services, KED also provided a clear international after-sales service solution:

• Remote technical diagnostics and software upgrades
• Online troubleshooting support
• On-site engineer support for non-human-caused failures during the warranty period
• Global overseas service capability with engineer dispatch support

If remote troubleshooting and firmware upgrades cannot resolve the issue, KED can arrange engineers to travel internationally and provide on-site technical service directly at the customer’s location.

Results & Impact

All 5 energy storage charging stations were inspected and confirmed to be operating normally during the local technical visit.

Key project outcomes included:

• Stable operation verified for all deployed charging systems
• Improved customer confidence through proactive local support
• Reduced operational risk through preventive inspection and diagnostics
• Comprehensive global after-sales support strategy established
• Enhanced long-term reliability and service assurance for commercial operations

The project demonstrated KED’s capability not only in manufacturing advanced EV charging equipment, but also in delivering responsive international technical support and global after-sales service for commercial customers.
