A battery cell monitoring system includes: a battery cell including an electrode stack disposed within a case; a gas sensor disposed within, attached to or connected to the case and configured to detect levels of one or more gases within the case; and a gas monitoring circuit connected to the gas sensor. The gas monitoring circuit includes: a memory that stores data collected from the gas sensor; a transceiver configured to transfer the data to a network device separate from the battery cell; and a control module that monitors the levels of one or more gases and based on the levels of the one or more gases detects (i) an issue with the battery cell during operative use of the battery cell, (ii) an issue with the battery cell during formation of the battery cell, or (iii) completion of a formation operation of the battery cell.

A method for using idle computing power of an electric vehicle includes receiving computing tasks while the electric vehicle is electrically connected to a charging infrastructure, accepting to perform the computing tasks while the electric vehicle is electrically connected to the charging infrastructure, and in response to accepting to perform the computing tasks, performing the computing tasks while the electric vehicle is electrically connected to the charging infrastructure.

Method and system for using idle computing power of an electric vehicle

A method for using idle computing power of an electric vehicle includes sending the computing tasks and the task rates for performing the computing tasks to a vehicle controller of the electric vehicle and receiving an acceptance signal from the vehicle controller. The acceptance signal is indicative that the vehicle controller accepted to perform the computing tasks. The method further includes commanding a charging infrastructure to supply electrical power the electric vehicle while the vehicle controller performs the computing tasks.

Presented are control systems for operating rechargeable electrochemical devices, methods for making/using such systems, and vehicles with intelligent battery charging and charging behavior feedback capabilities. A method of operating a rechargeable battery includes an electronic controller receiving battery data from a battery sensing device indicative of a battery state of charge (SOC). Using this battery data, the controller determines a number of low SOC excursions at which the battery SOC is below a predefined low SOC threshold and a number of high SOC excursions at which the battery SOC exceeds a predefined high SOC threshold. The controller then determines if the number of low SOC excursions exceeds a predefined maximum allowable low excursions and/or the number of high SOC excursions exceeds a predefined maximum allowable high excursions. If so, the controller responsively commands a resident subsystem to execute a control operation that mitigates degradation of the rechargeable battery.

Intelligent motor vehicles and control logic for managing charging of traction battery packs

A vehicle including a hybrid battery pack includes a first battery pack and a second battery pack. The first battery pack has a higher energy density than the second battery pack. The second battery pack has a higher power density than the first battery pack. A power inverter module is connected between the hybrid battery pack and a motor generator unit (MGU) that is connected to a powertrain of the vehicle. The power inverter module is configured to regulate power flow between the hybrid battery pack and the MGU. A battery management module is configured to: control switching of the power inverter module; selectively charge and discharge at least one of the first battery pack and the second battery pack; and selectively charge the first battery pack with power from the second battery pack.

A method of fabricating a curvilinear magnet includes forming at least one slot in a material billet. The slotted material billet is inserted into a mold having a curvilinear pocket. The mold is closed around the slotted material billet such that the slotted material billet conforms to the curvilinear pocket and forms a curvilinear billet. The curvilinear billet is arranged in a structure. The curvilinear billet arranged in the structure is then magnetized.

A smart trailer coupler system includes a ball mount connectable to a vehicle, a hitch ball mechanically connected to the ball mount, a coupler selectively connectable to the hitch ball, and at least one sensor mounted to one of the ball mount, the hitch ball and the coupler. The at least one sensor detects a size compatibility between the coupler and the hitch ball. A signal system is operatively connected to the at least one sensor. The signal system provides at least one of a visual alert and an audible alert of the size compatibility between the hitch ball and the coupler.

An engine includes a cylinder liner. The cylinder liner includes an interior wall, an exterior wall, and a thermoelectric element disposed therebetween. The interior wall forms a cylinder bore forming part of a combustion chamber. The exterior wall is positioned adjacent a coolant jacket. The thermoelectric element is operable to generate an electric current in response to a temperature gradient between the interior wall, which is exposed to the high temperatures of the combustion chamber, and the exterior wall, which is exposed to the cooler temperatures of a coolant in the coolant jacket. An electric current in a circuit of the thermoelectric element may be controlled to affect a cylinder wall temperature. The circuit of the thermoelectric element may be opened, and the voltage of the thermoelectric element may be measured and used to calculate the cylinder wall temperature.

Methods and systems for receiving, by a destination device at which a securement-monitoring application is operating, from a securement sensor device, a securement-condition communication indicating a condition of a securement remote to the destination device. Operations also include determining, by the destination device using the securement-monitoring application, an action to take responsive to the securement-condition communication, such as notifying a user of an undesired condition at the securement. The operations further include initiating the action determined.

Automated wireless securement-monitoring and feedback system

A system, apparatus and method for wireless communication in an ecosystem of wireless devices interconnected for assisting a vehicle, or a vehicle and trailer in maneuvers which includes at least one radio frequency (RF) system configured to operate as part of a vehicle system, a trailer system or combination thereof, or as an independent unit with wireless connectivity to the vehicle and/or trailer system or other independent unit to form the ecosystem of wireless devices interconnected. The RF system includes a transceiver for the wireless connectivity with extended range ultra-wide band capabilities wherein each RF system includes: at least one vehicle RF system, at least one trailer RF system and at least one independent RF unit system.

A system implemented at a user structure, to monitor a tracked object using a three-body arrangement including the user, a tracked object, and a controlling apparatus. The system has a data storage device including user-presence module code causing a processor to determine, based on wireless sensing, whether the user has entered a first space having a boundary external to the user structure, or has left the space. Object-presence module code causes the processor to determine, based on tracked-object-presence data, whether the tracked object is within a second space. And the storage device includes alert-module code to, in response to determining that, depending on the embodiment, (i) the user entered or exited the first space and (ii) the tracked object is or is not present within the second space, initiate provision of a system-user alert communication to indicate that the tracked object is not present within the second sensed space.
