AI Technical Summary
Technical Problem
Existing charging systems for electric vehicles fail to reliably notify drivers and other personnel of charging abnormalities, particularly when installed outdoors or during route charging, leading to potential oversight of error displays due to environmental factors or limited time.
Method used
A charging system with a controller that includes an abnormality detection unit, storage unit, human presence detection unit, and notification output unit, which notifies the person involved in charging upon contact or approach to the charging connector, using visual, auditory, or tactile alarms.
Benefits of technology
Ensures reliable notification of charging abnormalities only when a person is present, preventing missed alerts and minimizing unnecessary alarms.

Abstract
Ensure that drivers and other relevant parties are notified or informed of any abnormalities during charging. [Solution] This is a charging system for electric vehicles that charges by connecting a charging connector 6 provided on a charging cable to an inlet 7 and supplying power to a power storage device. The controller 22 that controls the charging by supplying power from the power supply unit to the power storage device includes an abnormality detection unit 21 that detects abnormalities in charging, an abnormality storage unit that stores the detected abnormalities, a human presence detection unit 9 that detects when a person involved in charging touches or approaches the charging connector 6 connected to the inlet 7, and a notification output unit 23 that notifies the person involved in charging that there has been an abnormality stored in the abnormality storage unit when the human presence detection unit 9 detects contact or approach of a person involved in charging.
