Abstract:
A vehicle power take off system provides power for a variety of systems including a source of alternating current power for conventional electrical equipment to be powered by the vehicle. In a preferred electrical implementation, the power take off system is energized from the vehicle direct current electrical power system and generates alternating current of the desired voltage using a derectifier and step up transformer. Management of the system is implemented through modularized units which may be connected to communicate with another over a vehicle's controller area network. Load management may be monitored by an existing on board computer.
Abstract:
An energy storage module (30, 32) for an electric vehicle or hybrid electric vehicle (12). Multiple low-voltage storage batteries (36) disposed on a tray (60) and connected in parallel circuit relationship form a low-voltage battery bank. A DC-to-DC converter (42) has an input connected to the low-voltage battery bank and an output connected to a high-voltage energy storage bank (34). An AC-to-DC converter (40) is connected to the low-voltage battery bank for charging the low-voltage battery bank from a source of AC electricity (45).
Abstract:
An exhaust gas turbine generator system for a vehicle that has an internal combustion engine with an exhaust system is provided. The exhaust system comprises a turbine, an electrical generator, a waste gate, and an electronic control module. The turbine is disposed in fluid communication with an exhaust gas system of an internal combustion engine to allow fluid flow between the turbine and the exhaust gas system. The electrical generator connects to the turbine. The waste gate is disposed in fluid communication with the exhaust gas system of the internal combustion engine. The waste gate is positionable between an open position and a closed position in response to an output signal from the electronic control module. The fluid flow in the exhaust gas system to the turbine is reduced when the waste gate is positioned to the open position.
Abstract:
When a truck engine (12) is not running, an auxiliary coolant heater (32) can heat engine coolant and pump it through an occupant compartment heater (16). A coolant flow control system (10), including a valve assembly (84), associates the auxiliary heater (32) with both the occupant compartment heater (16) and engine (12) for selectively distributing heated coolant. When engine (12) has been running and is shut off, auxiliary heater (32) can be turned on and valve assembly (84) operated for occupant compartment heating while keeping the engine (12) warm. When the engine is cold, the auxiliary heater can be turned on and the valve assembly can be operated for engine pre-heating prior to starting.
Abstract:
In a pneumatic brake system for a motor vehicle, a variable speed electric motor is connected to a high voltage direct current power supply for variable energization, thus varying the operating rate of a compressor and the rate of pressurization of the brake system storage tanks. The operating rate of the compressor is varied responsive to pressure readings taken from the storage tanks during pressurization to minimize energy consumption.
