System and methods for protection of battery modules |
| 摘要 |
A circuit includes multiple battery modules and protection circuits respectively coupled to the battery modules. Each protection circuit includes a controller and a shunt circuit. The controller is coupled to one of the battery modules and detects a fault associated with the battery module. The shunt circuit is coupled to the battery module and the controller, and shunts a current around the battery module if the fault associated with the battery module is detected by the controller. |

1. A system comprising:
a shunt circuit; and control circuitry, coupled to said shunt circuit, said control circuitry operable for detecting a fault in a plurality of battery modules, operable for controlling said shunt circuit to shunt a first current flowing from a negative terminal of a battery module of said plurality of battery modules to a positive terminal of said battery module if said fault is associated with said battery module and occurs during a discharging process of said battery modules, and operable for controlling said shunt circuit to shunt a second current flowing from said positive terminal to said negative terminal if said fault is associated with said battery module and occurs during a charging process of said battery modules. |
