First Claim
1. 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 for connecting to the electric apparatus and charging a second rechargeable battery, the charge system comprising;
a first charging part for charging the first rechargeable battery with the power supplied from the adapter;
a first interface for providing a power supplying path and connecting with the charger;
a power switch for switching the power supplying path between the electric apparatus and the charger via the first interface;
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 enable the first rechargeable battery and the second rechargeable battery be discharged in sequence when the adapter is not connected to the electric apparatus; and
a first discharging switch interposed between the first rechargeable battery and the power switch to switch driving power supplied from the first rechargeable battery, wherein the first controller enables the first discharging switch and the power switch to allow the charger to detect the power state of the first rechargeable battery via the first interface when the adapter is not connected to the electric apparatus.
