A Wireless battery area network permits the wirelessly monitoring and controlling of individual batteries within large-scale battery applications. The system automatically configures its wireless nodes in the network and provides for the linking of a plurality of batteries () to a master battery management unit (M-BMU) () by establishing a wireless battery area network within a battery pack that include slave units (S-BMU) (). The entire system may also be controlled by a top level battery management unit (T-BMU) (). The system and method allows for the monitoring of voltage, current, temperature, or impedance of individual batteries and for the balancing or bypassing of a battery.

Battery management system (BMS) for collecting data concerning battery cells in a battery pack includes a plurality of sensor nodes, each configured to be connected to at least one corresponding battery cell of a battery pack. The BMS also includes one or more master nodes configured to communicate with the sensor nodes in a at least a first communication session to receive battery cell data from the sensor nodes. The BMS also includes at least one top level node configured to communicate with the one or more master nodes in at least a second communication session. In this second communication session, the top level node receives the battery cell data from the one or more master nodes. To facilitate improved data acquisition times, the one or more master nodes are each configured to conduct the first communication session concurrent with the second communications session.

A battery sensing system acquires battery information of a battery string comprised of multiple battery cells connected in series. The system includes a plurality of battery sensing channels and a digital core including a control unit. Each of the battery sensing channels is configured to acquire inter-terminal voltages of a set of battery cells which are connected in series, so as to comprise at least a portion of a battery string. In some scenarios, the battery sensing system is a system-on-a-chip, disposed in a single integrated circuit package.

Battery Management System (BMS) which includes a plurality of master battery management units (M-BMU), each comprising at least one multi cell battery sensing device. The multi cell battery sensing device configured to directly sense one or more conditions associated with each battery cell of a group of battery cells that are associated with one battery module. The BMS also includes a plurality of sensor battery management units (S-BMU) associated with each of the battery modules. Each S-BMU is a single-cell battery sensing device arranged to directly sense one or more conditions associated with a particular battery cell. Each S-BMU is configured to wirelessly communicate data acquired as a result of the direct sensing to an M-BMU associated with the particular battery module.

Spatial-temporal compression of sensing data from a plurality of sensors involves using a plurality of sensors to obtain measured physical data associated with a plurality of sensed elements. At each of a plurality of sampling times a set of N sampled data is acquired from the N sensed elements corresponding to the measured physical data. The sets of sampled data are analyzed to obtain statistical characteristic information. Thereafter, one or more frames of compressed data is generated using the statistical characteristic information to facilitate temporal and spatial data compression.

Method for data communication involves receiving with a radio receiver a data signal containing a plurality of data symbols. An analog to digital converter obtain a sample of the data signal at periodic intervals to define a sampling rate which is N times a symbol rate. Thereafter, at least one processing device allocates each sample obtained to a respective one of N sampled data streams in accordance with an allocation sequence, and repeats the allocation sequence after every N samples so that each of the N sampled data streams has a data stream symbol rate equal to the symbol rate. Thereafter, a plurality of data stream data sets defined by the N sampled data streams are validated. Once the validation is completed, a plurality of groups are determined, each comprised of two or more of the stream data sets which have been validated and are identical.
