Beschreibung
Zusammenfassung:	The invention discloses an alternating current charging method and device for a new energy automobile and the new energy automobile. The method comprises the steps that whether the new energy automobile enters a healthy charging mode or not is detected; when it is detected that the new energy automobile enters the healthy charging mode, the environment temperature of the new energy automobile, the actual temperature of a power battery and the actual temperature of charging equipment are collected; according to the temperature of the environment where the new energy automobile is located, the actual temperature of the power battery, the actual temperature of the charging equipment and the corresponding temperature rise data, the optimal charging current of the power battery is calculated within the maximum allowable charging power of the power battery and/or the rated output power range of the charging equipment, and the new energy automobile is charged with the optimal charging current. The method realizes ac
