Problems solved by technology

[0002] In the prior art, there are generally two methods of charging electric vehicles, slow charging and fast charging. The slow charging method has a small charging current and slow charging speed, and the fast charging method has a large charging current and fast charging speed. Although the fast charging method can charge in a short time However, this high-current charging method will greatly shorten the life of the electric vehicle power battery, thus increasing the cost of charging
In addition, the existing slow charging and fast charging methods generally determine the specific charging current according to the specific power battery model, which cannot take into account the actual needs of the user. When the user needs more power in a short time, use The fixed charging current will not be able to meet the needs of users

Abstract

The invention discloses an electric vehicle battery swap station and a charging method thereof. According to the battery swap station, a first charging current can be calculated according to chargingexpectations inputted by a user, a second charging current can be calculated according to a charging initialization parameter of an electric vehicle power battery, the best charging current can be obtained by comparing the first charging current with the second charging current, charging of the electric vehicle power battery can be realized by using the best charging current, requirements of the user and the life of the power battery can be taken into account at the same time when the electric vehicle power battery charges, and the selection of a charging current meets the requirements of theuser, and the life of the power battery is prolonged as much as possible.
