SYSTEMS AND METHODS OF DIRECT CELL ATTACHMENT FOR BATTERIES |
摘要 |
Embodiments of the systems and methods of direct cell attachment for battery cells disclosed herein operate without the protection FETs and the protection IC, thereby enabling the direct attachment of battery cells to the system without compromising safety. A charger IC comprises a switching regulator whose output is used to charge the battery through a pass device. In example embodiments of the disclosed systems and methods of direct cell attachment, a combination of switching FETs and the pass device are used as a protection device instead of the charge and discharge FETs. During normal operation, the pass device may be used to charge the battery using the traditional battery charging profile. Under fault condition, the switching FETs and pass device may be driven appropriately to protect the system. |

1. A system comprising:
a battery protection circuit comprising:
a battery transistor configured in series between a charging source and a battery, the battery transistor also configured in series between a load and the battery, the battery transistor further configured to charge the battery under normal conditions, and configured to protect the load during fault conditions, the battery transistor further configured outside of a pack that houses the battery. |
