  • Patent number: 11145908
    Abstract: Methods and apparatuses for a listening only wireless network controller in a wireless battery management system are disclosed. A primary wireless network controller (WNC) receives battery sensor data from a plurality of module monitoring systems (MMSs). A secondary WNC also receives the battery sensor data from the MMSs. The secondary WNC is listening-only, in that it does not send commands to the MMSs. The listening-only WNC may be used to collect and provide redundant data for communication integrity or enhanced data for performance and diagnostic purposes. A collection of listening-only WNCs may be used to map locations of MMSs based on signal strength.

  • Patent number: 10684031
    Abstract: A system including a processor and sensor for installation inside an underground vault. The sensor monitors a parameter inside the vault and sends a monitoring signal to the processor. Based on the monitoring signal, the processor may provide data to a memory for storage and/or control signals to an interface for transmission to an external device located within the vault. The control signals instruct the external device to modify the environment inside the vault. The sensor may be positioned inside an enclosure, which is inside a housing. An air moving device moves air into or out of the enclosure thereby drawing air from the vault into the enclosure before the sensor monitors the parameter. A heat generating component may be positioned inside the housing and when generating heat prevents moisture from condensing therein. The system may include a power unit that draws power from a power source inside the vault.
