    Abstract: Methods and systems for dynamically estimating the core temperature of at least one cell in a battery. In one aspect, the method includes using a combination of estimations including one based on ohmic resistance and another based on a function of thermal energy transfer through the battery. A weighting factor may be used for each of the estimations as a way to calculating a core temperature. The estimation based on ohmic resistance may be made determined independently of a measured surface temperature of the battery or any of the cells in the battery.

    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: A method of determining a state of health of a battery in real time includes estimating a parameter value associated with the state of health of the battery and determining one or more of a terminal voltage, an accumulated charge, a state of charge, and a temperature of the battery. The method further includes determining, via a computing device, a reserve capacity of the battery based at least in part on the estimated parameter value and one or more of the terminal voltage, the accumulated charge, the state of charge, and the temperature of the battery.

    Abstract: In an embodiment, a hosted-on-premises meeting exchange server operates seamlessly with web meeting servers. For example, one computer-implemented method comprises receiving a request from a client computer to join a web meeting; determining whether the client computer is coupled to a local network which includes an on-premises-meeting exchange server; in response to determining that the client computer is coupled to the local network, joining the client computer to the web meeting at the on-premises-meeting exchange server when the on-premises-meeting exchange server has sufficient capacity, and otherwise joining the client computer to the web meeting at an off-premises-meeting exchange server; and in response to determining that the client computer is not coupled to the local network, joining the client computer to the web meeting at the off-premises-meeting exchange server.
