Patent Images
1. A battery swap system, comprising:
- a battery docking connector including;
a first connector to connect with a main battery;
a second connector to provide power to a device;
reserve power cell terminals for a reserve power cell to provide power to the device when the main battery is not connected to the battery docking connector;
a battery protection module coupled to the reserve power cell for controlling charge and discharge of the reserve power cell;
a battery recharge module coupled to the battery protection module to enable charging of the reserve power cell from the main battery at a limited rate to protect the main battery; and
a battery backup switch module coupled to the battery recharge module and to the battery protection module, the backup switch module to switch connections between the main battery and the reserve power cell depending upon whether the main battery is connected for enabling hot swap of the main battery.
