Publication number: 20230120239Abstract: Described herein are techniques of characterizing electrical characteristics of a battery cell. The techniques employ a battery monitor coupled to a battery to measure voltage of the battery cell when it is in a recovery state after application of a stimulus (e.g., discharging or charging the battery). The measured voltage of the battery cell in the recovery state is then used to generate a characterization of the battery cell. The characterization may be used, for example, to match the battery cell with one or more similar battery cells to be coupled in a battery pack. In another example, the characterization may be used to verify authenticity of the battery cell.Type: ApplicationFiled: December 19, 2022Publication date: April 20, 2023Inventors: Pieter Retief Kasselman, Rosemary B. Ryan, Shane O'Mahony, Brian Cox, Colin Gerard Lyden, Brendan Daly, Lewis Malaver

Publication number: 20220413054Abstract: Testing of a battery module can be conducted using monitoring electronics attached to the battery module. Stimulus can be applied to the battery module and removed. After removal of the stimulus, the monitoring electronics can collect signals from the monitoring electronics reflecting parameters of the battery module as it relaxes back to a non-stimulated state. The stimulus can be provided by test equipment or by components of a system in which the battery module, having attached monitoring electronics, is implemented. The monitoring electronics attached to the battery module can provide autonomous recording of signals associated with the battery module that can provide data regarding the status of the battery module or one or more batteries contained in the battery module.Type: ApplicationFiled: August 24, 2022Publication date: December 29, 2022Inventors: Shane O'Mahony, Joseph Caissie Bush, Colin G.

Publication number: 20220082627Abstract: Described herein is a device for autonomously monitoring a battery is provided. The device is integrated with the battery (e.g., by being electrically coupled to the battery). The device obtains measurement data by injecting electrical signals into the battery and measuring an electrical response of the battery. The device participates in an authentication protocol with a computing device to verify a unique identity of the device to the computing device. After performing the authentication protocol verifying the unique identity of the device, the device transmits battery data to the computer. Further, techniques for verifying the identity of the battery using measurement data obtained by the device are described herein. The techniques generate a battery signature using the measurement data that is then used to verify the identity of the battery. For example, the battery signature may be used to determine whether the battery is counterfeit or defective.Type: ApplicationFiled: September 14, 2021Publication date: March 17, 2022Applicant: Analog Devices International Unlimited CompanyInventors: Shane O'Mahony, Narsimh Dilip Kamath, Tze Lei Poo, Gina G.

Patent number: 9391578Abstract: An LIF receiver includes a receiver path comprising: a mixer for mixing a received RF signal with a local oscillator signal to provide an IF signal at a lower frequency than the received RF signal, a bandpass filter for filtering the IF signal, a PGA for amplifying the filtered IF signal, an ADC for converting the amplified filtered IF signal to a digital signal, a converter for converting the digital signal to a baseband digital signal, and an AGC for setting a gain of the PGA in response to a magnitude of the received RF signal. A programmable DC signal source injects a programmed DC offset signal into the amplified filtered IF signal converted by the ADC, and a signal sensor, operatively connected to the receiver path after the PGA, determines a polarity of PGA signal output for a programmed DC offset signal. A controller determines a programmed DC offset signal minimizing a magnitude of the baseband signal in the absence of a received RF signal for at least one gain setting of the PGA.Type: GrantFiled: June 11, 2014Date of Patent: July 12, 2016Assignee: Analog Devices GlobalInventors: Muhammad Kalimuddin Khan, Michael J.
