Methods and apparatus utilizing time division access of multiple radar transceivers in living object detection for wireless power transfer applications are provided. In one aspect, an apparatus for detecting an object in a detection area of a wireless power transfer system is provided. The apparatus comprises a plurality of radar transceivers. The apparatus comprises a processor configured to group the plurality of radar transceivers into pairs of radar transceivers. The processor is configured to instruct each of the pairs of radar transceivers to transmit radar signals during a corresponding time slot of a plurality of time slots. The processor is configured to instruct each of the pairs of radar transceivers to receive the radar signals during the corresponding time slot of the plurality of time slots. The processor is configured to detect the object in the detection area based on at least some of the radar signals received by each of the pairs of radar transceivers.

A cell monitoring apparatus includes a processor and memory arranged to execute code representing a linear time-invariant state transition model and a non-linear observation model are provided to model a rechargeable cell using at least a non-linear open circuit voltage, an internal resistance, a time-invariant distortion voltage across a reactive component block, and a distortion current component constituting an error of measurement of current flowing through the reactive component block. An estimator unit performs extended Kalman filtering in respect of the state transition model and the observation model using the input state data in order to generate output state data. The processor is arranged to evaluate a criterion associated with at least part of the output state data and to generate a control signal in response to evaluation of the criterion.
