Battery charging circuit integrated inside battery pack
Battery charging systems having battery charging circuits are described. The battery charging circuit can be located within a battery housing. Alternatively, the battery charging circuit can be located within a charging shoe housing. Also described are power source modules. In addition, various methods of charging and discharging are described.
1. A battery charging system comprising:
a battery including at least one battery cell and a housing, the housing defining an interior region;
a battery charging circuit;
a battery management system;
a microcontroller;
a charging port;
a power source module including:
an AC/DC power circuit;
a USB power delivery controller;
a low power DC power circuit, the low power DC power circuit including (i) a wireless connectivity component, (ii) provisions for memory storage, and (iii) a microcontroller;
wherein the battery charging circuit is disposed in the interior region of the housing.
2. The battery charging system of claim 1 wherein the at least one battery cell includes a lithium ion cell.
3. The battery charging system of claim 1 wherein the battery management system, the microcontroller, and the provisions for memory storage are disposed in the interior region of the housing.
4. The battery charging system of claim 1 wherein the charging port is accessible along an exterior region of the battery.
5. The battery charging system of claim 1 wherein the charging port is configured to connect with a USB-Type C Connector.
6. The battery charging system of claim 1 wherein the power source module further includes:
a USB connector;
USB communication provisions.
7. The battery charging system of claim 1 wherein
the battery further includes a USB connector and switching provisions;
wherein the switching provisions (i) detect which of the charging port and the USB connector was first connected to external components, and (ii) disable the other.
8. The battery charging system of claim 7 wherein if the charging port and the USB connector were connected to external components at the same time, the switching provisions enable the charging port and disable the USB connector.
9. The battery charging system of claim 1 wherein the provisions for memory storage are for storing information and data.
