[Consumerwide - Jinil Kang Reporter / Yohan Bok Reporter]  LGUplus was presenting an electric charging service, Voltup, during the EV Trend Korea exhibition held at Coex Seoul between the 6th and 10th. The Boltup is made of Safety-up and Cable-Up charging systems, which you could experience at the boot. In particular, the physical Cable-Up charging system was exhibited at the hall. So we could try them out.

There were plenty of people entering the hall at 10.a.m. on March 6, in particular the LGU booth.

The Cable-Up charging system of LGU+, which was invented last year, caught eyes and was physically displayed at the booth. The charger is a ceiling style of EV charger, and one charger can cover four sections of a parking lot. We got to hear details of the charger at the booth from staff.

At the charging kiosk, you've got to choose a charger where his vehicle is located. As soon as he tags his charging card to a reader device, a button with a "please down your connector" message appears. When you press the button, a connector begins to move down to charge your EV. When you connect it to your car, it starts to charge. After completion, when the user presses the connector up button at the kiosk, the charging connector returns to the ceiling. Whether you press the connector up button or not, it returns to the ceiling if it was left without any action for over 3 minutes. This system hasn't been released yet, but will be released in full scale after their first installation at Hanhwa Forena apartment.

An assistant at the booth said, "The Cable-Up charging system is installed on the ceiling of the parking lot. It prevents charging connectors from pollution or water sinking while not taking up much space on the floor surface. With one charger, it can serve four sections of parking lots, so we get plenty of space."

Regarding the charging method, the assistant said, "With a small amount of electric power, it covers three EVs simultaneously by using the road balancing technology. The first connected EV is charged with 7 kWh, and the rest of the EVs have 3 kWh. When the first EV gets over with charging, the next EV gets 7 kWh. We can charge a number of EVs with a small amount of electric power."

About fire prevention technology, the assistant said, "The Cable-Up charging system does not have additional fire prevention technology, which we plan to enhance in the future. However, the Safety-Up charging system contains fire prevention functions such as automatic electricity cuts in the case of overheating and overelectricity."

The Safety-Up charging system was exhibited at the booth. The system contains fire prevention functions such as automatic electricity cut in the case of overheating or overelectricity, auto charging without tagging or an app using action (auto recognition of the user), a real-time charging camera recorder for safety checks, and a blackbox function that records problem moments during charging. All these functions were demonstrated through videos in the exhibition hall. The charger proposes a future of EV chargers, which users can expect.
