Zusammenfassung: | The invention discloses a battery manger and a reserve power supply for a wind power variable pitch system. The battery manager includes a power module and a processor. The processor is connected with an isolation charge module, a voltage detection module, an inner resistance detecting module and a temperature detecting module. The isolation charge module, the voltage detection module, the inner resistance detecting module and the temperature detecting module are all connected with a to-be-detected battery. The power module provides working power for the processor, the isolation charge module, the voltage detection module, the inner resistance detecting module and the temperature detecting module. The inner resistance detecting module detects real inner resistance value of the to-be-detected battery. If the real inner resistance value is greater than a set inner resistance reference value of the processor, that the to-be-detected battery is a fault battery is judged. The power battery manager provided by the |
