Abstract: A method for controlling charging and discharging of a battery pack for an electric or hybrid vehicle to prevent overheating damage. Current flowing into or out of the battery pack is monitored, and root mean square (RMS) current is integrated over a time window and compared to a threshold to determine if power needs to be regulated in order to prevent damage to the cells in the battery pack. If the time-integrated RMS current exceeds the threshold, a closed-loop proportional-integral (PI) controller is activated to regulate power input or output. The controller will continue to regulate power until the time-integrated RMS current drops below the threshold. Various thresholds can be defined for different time windows. The gains used in the PI controller can also be adjusted to scale the amount of power regulation.

Abstract: Methods and systems are provided for calibrating one or more limits of a battery of a vehicle, the battery having state of charge limits and power limits. A history of environmental conditions for the vehicle is obtained and stored in a memory. One or more of the state of charge limits, one or more of the power limits, or both are adjusted based on the history of environmental conditions and usage severity using a processor.

Abstract: A method and system for selectively using a voltage-based state of charge estimate in an overall state of charge calculation. Regions or bands of battery pack state of charge are established, where in some regions, open circuit voltage is known to be a good indicator of state of charge, and in other regions, open circuit voltage is known to be a poor indicator of state of charge due to a high sensitivity to measurement error. In regions or bands where voltage-based state of charge is expected to be accurate, the voltage-based state of charge estimate may be used to scale or adjust a current-based state of charge estimate, thus avoiding a continuous accumulation of error in the current-based estimate. In regions or bands where voltage-based state of charge is known to be prone to error, only current-based state of charge information is used.

Abstract: A digital pulse-width modulator is provided that receives a digital command input signal and a secondary control input signal and provides a pulse-width-modulated output signal. The pulse-width-modulated output signal comprises a pulse-width that corresponds to an integer number of slots each having a time duration. The integer number of slots corresponds to a value of the digital command signal, and the time duration is determined based upon the secondary control input signal. In one embodiment, the digital pulse-width-modulator comprises a plurality of delay cells arranged in series for propagating a clock signal through the plurality of delay cells. A time delay for each of the delay cells is determined by the secondary control input signal.

Abstract: The use of an agent for controlling vascular permeability within the cervix is disclosed for controlling cervical ripening. To hasten cervical ripening, the agent is one which increases vascular permeability and is selected from VEGF121, VEGF145, VEGF165, VEGF189, VEGF206, a smaller, active VEGF fragment, and placenta growth factor (PlGF). If cervical ripening is to be delayed, the agent is one which reduces vascular permeability, e.g. a VEGF receptor antagonist or antibody. The agents of the present invention can be used as a means of managing labor.
