Advanced battery early warning and monitoring system |
摘要 |
Systems, apparatuses and methods for detecting internal cell faults using online and real-time sensing techniques, and providing an accurate and reliable early warning for the incoming failure of battery cells hours or days prior to failure. A system is configured to perform real-time and direct measurement of battery cell parameters of temperature, voltage, and AC impedance through online sensing. These parameters may be simultaneously processed using advanced probabilistic and/or fuzzy logic-based algorithms to provide an early warning for the incoming failure of battery cells in a battery pack. This technology may safeguard the LIB battery packs while allowing them to operate at or near 100% capacity in both transportation and stationary applications. |

1. A system for monitoring and predicting battery faults, comprising: at least one of a plurality of relays that is used to control the input of voltage to a plurality of battery modules, at least one of a plurality of sensors that is used to detect incoming current or voltage difference, at least one of the plurality of battery modules that is operatively coupled with a set of equalization current lines and a set of voltage sense lines to a pack management system, wherein the at least one of the plurality of battery modules is indexed to provide individual measurements that are forwarded individually to a monitor system, which processes these measurements and provides an output that is utilized to determine a state of-health or a warning of a failure condition. |
