A method for operating a vehicle hybrid propulsion system is described. During a vehicle speed control operation where a speed of the vehicle is maintained at a desired speed, in response to acceleration resulting in vehicle speed beyond the desired speed, the acceleration not caused by vehicle operator input, the torque output of an upstream and / or downstream electric energy conversion device provides brake torque to a drive wheel to decelerate the vehicle to the desired speed. The selection of the electric energy conversion device may be based on an operating condition to achieve improved control and efficiency.

The invention provides a charging state monitoring device, comprises a switch monitoring module and a state judging module, wherein the switch monitoring module is used for monitoring the state of a circuit charging switch connected with a battery inside a terminal; and the state judging module is used for determining the battery to be in a negative charging state when the circuit charging switch is in an on state and determining the battery to be in a charging state when the circuit charging switch is an off state. Correspondingly, the invention further provides the terminal and a charging state monitoring method. By means of the technical scheme provided by the invention, a user can be informed of the true charging state of the terminal, and a proper suggestion can be provided to make the user adopt a correct measure so as to optimize the charging state of the terminal and shorten the charging time.

The present invention provides a power source system that increases the power supply capacity of a power source device and continuously supplies the power necessary for a load device when a power source device stops. A control unit has a state quantity setting unit that sets a first target state quantity indicating a state of charge of the power storage device that is to be a target value when charge and discharge of the power storage device are controlled. When the power source device stops, the state quantity setting unit can change the first target state quantity to a second target state quantity that is to be a target value exceeding the first target state quantity and can increase the target state quantity of the power storage device. As a result, when the power source device stops, charge and discharge of the power storage device are controlled on the basis of the target state quantity exceeding that during the operation of the power source device. Therefore, the state of charge of the power storage device can be improved over that during the operation of the power source device. As a result, the power supply capacity of the power source device can be increased and the power necessary for the load device can be continuously supplied, in place of the power source device.

Relative quantification of metabolites by Electrospray Ionization Mass Spectrometry (ESI-MS) requiring a mechanism for simultaneous analysis of multiple analytes in two or more samples. Labeling reagents that are reactive to particular compound classes and differ only in their isotopic kit facilitating relative quantification and providing tangible evidence for the existence of specific functional groups. Heavy and light isotopic forms of methylacetimidate were synthesized and used as labeling reagents for quantification of amine-containing molecules, such as biological samples. Heavy and light isotopic forms of formaldehyde and cholamine were also synthesized and used independently as labeling reagents for quantification of amine-containing and carboxylic acid-containing molecules, such as found in biological samples. Advantageously, the labeled end-products are positively charged under normal acidic conditions involving conventional Liquid Chromatography Mass Spectrometry (LC / MS) applications. Labeled primary and secondary amine and carboxylic acid end-products also generated higher signals concerning mass-spectra than pre-cursor molecules and improved sensitivity. Improved accuracy concerning relative quantification was achieved by mixing heavy and light labeled Arabidopsis extracts in different ratios. Labeling strategy was further employed to ascertain differences in the amounts of amine-containing metabolites for two strains of Arabidopsis seeds.

A power switcher mechanism includes an internal combustion engine, a generator motor, a controller and a power interrupter. The internal combustion engine outputs a power. The generator motor carries out electric power generation as well as outputs a power when a power is input. The controller selects and then controls the internal combustion engine and the generator motor as a driving source for running. The power interrupter connects the generator motor with a power transmission route for transmitting the power and then disconnects the generator motor from the power transmission route, or vice versa, intermittently. The controller activates the power interrupter and then deactivates it, or vice versa, intermittently, with reference to information on road conditions, information on traffic conditions or information on vehicular conditions.

A power supply control section calculates a target charge / discharge current of a secondary power supply apparatus based on an actual charged amount and a target charged amount of the secondary power supply apparatus, and feedback-controls the stepped-up voltage of a step-up circuit such that an actual charge / discharge current detected by a secondary current sensor coincides with a target charge / discharge current. When the actual charged amount (1) is equal to or greater than the target charged amount, the target charge / discharge current is set to zero to prevent overcharging, and (2) is less than the target charged amount, a target charge current corresponding to a capacity margin of the step-up circuit is set to quickly charge the secondary power supply apparatus. When the output of the step-up circuit has no margin, the target charge / discharge current is set to zero.

A system, computer readable storage device and method for controlling torque in a hybrid electric vehicle. The method comprises determining a state of charge of an energy storage device, obtaining a reference state of charge, obtaining an error from a difference between the determined state of charge and the reference state of charge; and apportioning torque between a motor and an engine based upon the error. The motor is electrically coupled to the energy storage device and powered by the energy storage device. A state of charge (SOC) correction factor is determined based upon the error. The SOC correction factor is used to adjust a torque ratio of motor to engine torque that is determined for a given torque command.
