  • Patent number: 12668148
    Abstract: In some embodiments, an electric vehicle (EV) includes an energy storage, a navigation system, and a vehicle management system configured to receive, from the navigation system, parameters associated with preconditioning the energy storage for charging, precondition, while travelling to a destination charger and based on the parameters, the energy storage to a target temperature, and charge the energy storage to a target state of energy using the destination charger.

  • Publication number: 20260158854
    Abstract: A vehicle may include a body; a plurality of heat producing components within the body; an air intake through which air is provided from outside the body to dissipate heat from the heat-producing components; a shutter configured to control an amount of airflow through the air intake through control of a position of the shutter; and a controller configured to control the position of the shutter based on a cost function, wherein the cost function accounts for an aerodynamic drag of the vehicle and a rate of heat extraction from the heat-producing components, wherein the aerodynamic drag of the vehicle and the rate of heat extraction from the heat-producing components each depend on the position of the shutter.

  • Patent number: 12623660
    Abstract: A computer-implemented method of performing static heating of an electric motor comprises: applying a brake to a wheel of a vehicle that has an electric motor; determining an incline of the vehicle; and in response to the incline being within a first incline range, providing first current to the electric motor for static heating, the first current selected so as to not produce torque in the electric motor.
