The embodiment of the invention relates to the technical field of electric vehicles, and discloses a charging method and device and an electric vehicle. In the method, after the insulation detection voltage of a charging pile is determined, the charging capacity of the charging pile can be determined through the insulation detection voltage, and when it is determined that the charging capacity of the charging pile can support first voltage charging, the charging capacity of the charging pile can support second voltage charging; and first configuration information is transmitted to the charging pile, the first configuration information indicates the charging pile to charge the electric energy storage device through a first voltage, and the first voltage is higher than a preset voltage. According to the technical scheme, the charging capacity of the charging pile can be detected in advance through the insulation detection voltage of the charging pile, so that when the charging pile can provide high charging vol
