Abstract
The present invention relates to a charge system comprising an electric apparatus that comprises a first rechargeable battery and an adapter for supplying power to the first rechargeable battery, and a charger connected to the electric apparatus and used to charge a second rechargeable battery. The charge system employs a first charging part for charging the first rechargeable battery with the power supplied from the adapter, a first interface for forming a power supplying path and connecting to the charger, a power switch for switching the power supplying path between the electric apparatus and the charger via the first interface, and a first controller for controlling the first charging part and the power switch to enable the first rechargeable battery and the second rechargeable battery to be charged in sequence when the adapter is connected to the electric apparatus in the state that the charger is connected to the electric apparatus, and control the power switch to make the first rechargeable battery and the second rechargeable battery be discharged in sequence when the adapter is not connected to the electric apparatus.
