Abstract

Aspects of the present disclosure relate to an electric or hybrid vehicle. Aspects of the vehicle may be used to provide a variety of functionality, including power exporting and aggregation, power take off functionality, thermal signature reduction, and improved vehicle longevity, vehicle turning, and vehicle control techniques.

Claims29

Dependent claims

A vehicle, comprising:

a plurality of ground engaging members;
a frame supported by the plurality of ground engaging members;
a cooling system supported by the frame and configured to cool a heat source of the vehicle, the cooling system including a radiator coupled to a coolant flow controller;
and
cooling controller circuitry to control the cooling system, the cooling controller circuitry configured to:
configure the coolant flow controller to direct heat from the vehicle heat source to the radiator to dissipate the heat at the radiator in a first operating mode;
and
configure the coolant flow controller to direct heat from the vehicle heat source to a battery of the vehicle to dissipate the heat at the battery in a second operating mode;
wherein the cooling controller circuitry is further configured to cause the cooling system to dissipate the heat at an increased rate compared to the first operating mode, prior to operating the cooling system in the second operating mode.

A vehicle, comprising:

a plurality of ground engaging members;
a frame supported by the plurality of ground engaging members;
a cooling system supported by the frame and configured to cool a heat source of the vehicle, the cooling system including a radiator coupled to a coolant flow controller;
and
cooling controller circuitry to control the cooling system, the cooling controller circuitry configured to:
configure the coolant flow controller to dissipate heat at an increased rate as compared to a normal mode of operation of the cooling system;
configure the coolant flow controller to direct heat of an electric motor of the vehicle to a battery pack of the vehicle, thereby reducing a thermal signature of the vehicle associated with a radiator of the cooling system;
evaluate a temperature of the battery pack based on a first predetermined threshold;
and
based on a determination that the temperature of the battery pack exceeds the first predetermined threshold, configure the cooling system to direct heat of the electric motor to a set of electronics of the vehicle, wherein the set of electronics includes components of a power system of the vehicle that are located separately from the battery pack.
