摘要:
A battery system is provided for a vehicle. The battery system includes, but is not limited to, comprising: a heat transfer loop, a battery cell, a thermoelectric semiconductor device coupled to the battery cell and the heat transfer loop, a variable voltage source coupled to the thermoelectric semiconductor device, and a temperature sensor coupled to the battery cell. A controller is coupled to the variable voltage source and the temperature sensor and also configured to receive a signal indicative of a temperature of the battery cell from the temperature sensor and adjust a voltage of the variable voltage source applied to the thermoelectric semiconductor device based at least in part on an evaluation of the temperature.
摘要:
A battery cell for an electric vehicle battery pack, including surface-applied wires to facilitate connecting the cell to a controller. Resistive or non-resistive wiring is printed onto or otherwise applied to the outer surface of the battery cell, to eliminate the need for separate jumper wires routed around or through the battery pack. A surface-applied wire is directly connected to each terminal of the battery cell, and each wire is routed on the outer surface of the cell to a location convenient for connecting a cell monitoring controller. The surface-applied wires can be made of a suitable resistive material, such that the resistance of each wire is known and the wires can be used for dissipating power during cell state of charge equalization. An insulating layer can be applied over the surface-applied wire to minimize the risk of short circuit.
摘要:
A fuel cell system that employs a closed coolant loop. The system includes an expansion device having a flexible membrane, where a cooling fluid side of the membrane is in fluid communication with the cooling fluid in the coolant loop and an air side of the membrane is in communication with an air pocket. The air side of the expansion device is in air communication with an air compressor so that the pressure of the cooling fluid within the coolant loop changes as the stack pressure changes. The fuel cell system also includes a coolant reservoir that is in fluid communication with the cooling fluid in the coolant loop. Air and hydrogen bubbles within the cooling fluid are vented to the coolant reservoir where they accumulate. The coolant reservoir includes a level sensor indicating the level of the cooling fluid therein.
摘要:
A mechanization of a fuel cell system and a method of operating the same is provided which simplifies the start-up of the fuel cell system. The fuel cell system can be started up without using any battery derived high voltage power to drive a high voltage compressor. The present invention provides for the use of a low voltage blower to provide oxygen to the cathode side of the fuel cell stack to enable start-up of the fuel cell stack without the initial use of a high voltage compressor. The low voltage blower can be powered by a low voltage power source and/or the voltage produced by the fuel cell stack.
