Abstract

A cathode active particles for use in a cathode of a lithium ion battery comprising a core includes a lithium-manganese-rich oxide and a coating on the core, wherein the coating includes a lithium manganese spinel. The cathode active particle can be made by preparing a dispersion of particles comprising a lithium-manganese-rich metal oxide in an aqueous solution of a salt of a transition metal oxide. The dispersion is mixed, and heated to a temperature in a range of 60 to 125° C. The solids are separated from the dispersion, and calcined. The cathode active particles can be used in cathode and in a battery comprising such cathode.

Abstract

A radial flux electric motor includes a stator having a radially inner stator surface and a rotor mounted inside the stator. The rotor defines a rotational axis and has axially opposite rotor ends and a radially outer rotor surface positioned proximate the radially inner stator surface, thereby establishing an airgap therebetween. The rotor also includes a fluid circulation arrangement having at least one fluid channel extending through the rotor to the radially outer rotor surface and configured to receive a liquid via a first passage and a gas via at least one second passage. The fluid circulation arrangement is also configured to direct the liquid and the gas, via centrifugal force, into the airgap as the rotor rotates inside the stator sufficiently to discharge the liquid and the gas out of the airgap at the axially opposite ends of the rotor, thereby cooling the electric motor.

Abstract

A voice controlled autonomous driving system for determining a trajectory of a vehicle based on a voice command includes one or more controllers executing instructions to receive an electrical signal representative of the voice command, where the voice command indicates a driving maneuver. The controllers convert the electrical signal into a text-based command, classify the text-based command into one of a plurality of pre-compiled driving maneuvers based on one or more machine learning algorithms, and classify the pre-compiled driving maneuver as either a route-based maneuver or a behavior-based maneuver, and in response to determining the precompiled driving maneuver is a route-based driving maneuver, identify one or more relevant lane segments of the map data affected by the pre-compiled driving maneuver and determine an updated route plan by updating a current route plan the vehicle is presently following to include the one or more relevant lane segments.

Abstract

A method that includes performing a battery module functionality test on battery cell arrays within the battery module to obtain battery test data for each of the battery cell arrays. The battery test data is used to determine if a measured parameter for one of the battery cell arrays deviates from a predetermined threshold for the measured parameter. A focused secondary battery test is performed on each of the battery cell arrays having the measured parameter that deviates from the predetermined threshold. The battery module is then qualified based on at least one of the battery test data and the focused secondary battery test.
