Abstract

The present invention relates to a method for displaying information of a battery pack based on a mobile terminal. The battery pack is used to supply electric energy to an electric tool. The method includes: establishing wireless communication with the battery pack; acquiring status information of the battery pack; and displaying the status information on the mobile terminal according to the acquired status information. In this way, as long as a user carries a mobile terminal that wirelessly communicates with a battery pack, status information of the battery pack can be displayed. The operation manner is simple, convenient, and easy to realize, which improves user experience.

First claim

1 - 35 . (canceled)
