US Patent 11642976 Vehicle, charging equipment, and charging method for vehicle

In external charging, a first threshold voltage and a second threshold voltage which is lower than the first threshold voltage are set. The ECU permits start of charging of a battery when a voltage of the battery is lower than the second threshold voltage. The ECU stops charging of the battery and notifies the user that the battery has been fully charged using an HMI when the voltage of the battery is higher than the first threshold voltage during charging of the battery. The ECU notifies the user that the battery has been fully charged using the HMI when the voltage of the battery after charging of the battery has been stopped is lower than the first threshold voltage and is higher than the second threshold voltage.
