Abstract:
A system for storing electrically a regenerative energy of a vehicle is provided. The system includes a first energy storage device, a second energy storage device, an energy regulating device coupled to the first and second energy storage devices, a source of regenerative power configured to capture a regenerative energy during a regenerative power event of the vehicle, and a control unit coupled to the energy regulating device. The control unit is configured to transfer electrical energy from the first energy storage device to the second energy storage device based on a prediction of the regenerative power event using the energy regulating device. The transfer of the electrical energy serves to reduce the electrical energy stored in the first energy storage device thereby enabling the first energy storage device to receive from the regenerative power device when the predicted regenerative power event occurs an amount of the electrical regenerative energy.

Abstract:
A battery warming-up system includes a main battery, an electric heating portion, and a control device. The main battery is mounted to a vehicle to supply an electric power to drive the vehicle, and is warmed by a heat generation of an inner resistance of the main battery according to an input and output of the electric power. The electric heating portion heats a compartment of the vehicle by using the electric power supplied from the main battery. The control device controls a temperature of the main battery by controlling a power supply from the main battery to the electric heating portion. The output of the main battery is increased by increasing the power supply from the main battery to the electric heating portion, and the main battery can be suitably warmed. Therefore, since a power loss due to a decrease of the inner resistance of the main battery is improved or the battery output becomes sufficient, the driving power of the vehicle can be properly ensured.
Abstract:
A vehicle or other system includes a flow device, component, and controller. The controller executes a method of diagnosing flow performance in the vehicle/system. The flow device is a pump, blower, or fan. A calibrated upper speed limit is commanded from the flow device in response to detected enabling conditions. The device is turned off after maintaining the upper speed limit for a calibrated duration. The speed of the flow device is determined during a coast-down interval defined by a period between command of the upper speed limit and attaining a calibrated lower speed limit. An absolute rate of change of the speed over the coast-down interval is calculated, with the controller executing a control action when a maximum absolute slope of the calculated rate of change falls outside of a calibrated range during the coast-down interval.

Abstract:
An electric or hybrid-electric vehicle is provided with vehicle-mounted solar cells capable of generating electrical power. The power from the array is directed to vehicle systems according to a pre-determined algorithm intended to most effectively extend the vehicle range when operated under electric power. Power from the solar cells is directed by a controller, and may be applied to directly charge the batteries or to power electric power receiving devices, for example, to control cabin temperatures, depending on factors including the state of charge of the batteries, whether or not, the vehicle is parked and the current cabin temperature. The controller is also capable of controlling and managing the operating voltage of the solar cells to ensure optimal power extraction from the cells.
Abstract:
Embodiments of the invention may include various components for cooling the heat generating components of a vehicle. For example, one component may be a radiator core or heat sink disposed near the bottom of the vehicle to absorb heat from the various components. In another example, cooling liquid is routed via liquid routing means to the various components for cooling (and also to the above described heat sink/radiator core, if applicable). Said liquid may be routed from the main chassis from a reservoir system within the vehicle, possibly delivered via power delivery wires. Furthermore, embodiments of the invention may utilize said circulating liquid to distribute heat generated by the heat sources of the system to one or more heat sinks of the system (e.g., a cabin heating subsystem).
Abstract:
A method of charging a rechargeable battery pack installed in an electric vehicle is provided in which the charging system includes a switching circuit that is operable in at least a first mode and a second mode. In the first mode the switching circuit couples the power supply and an external power source to both a heater and the charging circuit, the heater providing a voltage divider circuit within the charging circuit. In the second mode the switching circuit couples the power supply and the external power source only to the charging circuit, bypassing the heater.
