  • Patent number: 8643329
    Abstract: An overhead mobile charger system for mounting between a pair of adjacent and spaced-apart rows of side-by-side parking spaces and exhibiting full circle traversing so as to reach and charge electric vehicles parked in the pair of adjacent and spaced-apart rows of side-by-side parking spaces. The system includes a single EV battery charger, a boom, and apparatus for rotatably mounting the boom over, and between, the pair of adjacent and spaced-apart rows of side-by-side parking spaces. The single EV battery charger has a power cable terminating in an EV connector. The power cable of the single EV battery charger runs along, and depends from, the boom, and together with the boom being rotatably mounted via the apparatus so as to allow the boom to exhibit full circle traversing, the electric vehicles parked in the pair of adjacent and spaced-apart rows of side-by-side parking spaces are reached and charged by the EV connector of the single EV battery charger.

  • Publication number: 20130285446
    Abstract: Disclosed herein are power management systems for controlling recorded electrical demand by isolating loads from a utility distribution grid connection. The loads are isolated when an energy storage system (ESS) is placed in series between the loads and the grid, with a charger that keeps the ESS from depleting and a power converter that provides energy to the loads from the ESS. A system controller may be enabled to manage the charging of the ESS by the charger relative to a consumption metric. In some embodiments, the loads are categorized, controlled, or curtailed by the controller and may be isolated from other loads. Some embodiments include bypass features or bimodal connections. Additional methods of control to prevent depletion of the ESS are also set forth. Systems herein can prevent or limit demand charges, protect the utility grid from backflow and other dangers, and raise the customer's effective utility service limit.

  • Publication number: 20130221929
    Abstract: The electrical consumption mitigation provided by energy storage systems can be unreliable when a consumption peak lasts long enough to deplete the energy stored and the remainder of the peak is unmitigated. By implementing a waiting period between detecting the peak and discharging the energy storage in which characteristics of the peak are observed, a peak mitigation system can lengthen the effective discharge duration of the energy storage system and prevent unmitigated plateaus from appearing. For example, when a consumption plateau is detected, the system may discharge at a slower rate than when a spike is detected in order to prolong mitigation activities before the conclusion of the plateau. Thus otherwise-incurred demand-related utility charges can be reduced without having to increase the capacity of the mitigation system. In some cases, these processes are performed with respect to the bounds of demand-averaged time periods used to calculate demand charges.

  • Publication number: 20130193928
    Abstract: Charging and discharging an energy storage device (ESD) generates heat and may prevent its temperature from dropping to unsafe levels. By monitoring and managing the charge and discharge of an ESD with respect to the periods of time in which demand charges are determined, the heating will have minimal adverse effect on demand charges. ESDs may also exchange energy in a controlled manner for heating purposes and reduce reliance on utility grid-based energy sources. ESD heating may also be made more efficient by offsetting the heating with load shedding during charging periods. Precharging the ESD while heating or preheating the ESD by charging and discharging can prevent new maximum demand levels from appearing and thereby limit increases in demand charges.

  • Publication number: 20130194847
    Abstract: Universal electrical power conversion methods and systems which may provide the combined capabilities of symmetrical and asymmetrical conversion, bidirectionality, and simplicity are provided. In some cases, the converter charges an inductor connected in parallel between a regulated port and an unregulated port using energy stored by a capacitor positioned in parallel between the inductor and one of the ports until the inductor has a level of current stored that corresponds to the change in voltage desired at the regulated port, then discharges stored energy into the other port until a current cutoff threshold level is reached in the inductor. Creating an LC tank circuit during conversion allows conversion processes to traverse sinusoidal discharge patterns. In some embodiments, the inductor is precharged with current to affect the discharge of the inductor. Multiple ports can be connected and disconnected from the same inductor with these methods and systems.

  • Publication number: 20130147264
    Abstract: A system and method of use of a three-phase inverter driver is disclosed. In some exemplary embodiments three single-phase inverters are connected to the three-phase AC input of electric vehicle supply equipment (EVSE) so that each of the single-phase inverters provide one of the three phases of the AC signal used by the EVSE. The single-phase inverters are rectified and either have variance in their output frequencies or have their phases staggered so that the maximum voltage provided to the EVSE remains at a consistently high level. In some cases, the three phases each cross polarity simultaneously, resulting in a drop in the maximum three-phase voltage, so low-capacity capacitors are used in conjunction with the inverters to bridge these gaps in voltage. Embodiments use readily available, inexpensive components that have regulatory safety-approval and therefore may allow implementation on a vehicle or with a load leveling energy storage system.

  • Publication number: 20130030590
    Abstract: An apparatus and method for managing consumption of electricity of loads at a site which includes energy storage, a system controller, and load shedding ability. The system controller monitors energy consumption of the site and discharges energy into the site when consumption exceeds a maximum consumption threshold. If energy storage is depleted while consumption remains in excess of the threshold the controller may engage load shedding to prevent consumption from exceeding the maximum threshold. Additionally, the energy storage device may recharge during a peak consumption period due to load shedding reducing consumption below the maximum threshold, and the energy storage device may use this recovered energy to further mitigate the peak; in some embodiments, repetitively. Supplemental and additional load mitigation techniques may also be implemented to increase effectiveness and efficiency of the systems and methods.

  • Publication number: 20130018821
    Abstract: Some embodiments are systems which calculate the amount of electric power that a peak mitigation system provides in real time and translate that information into a real-time estimate of a peak utility usage charge that appears on the utility bill of the customer. These systems may facilitate a determination of the monetary value of demand charges saved by peak mitigation and load leveling and a notification to a customer of the savings realized. Some systems described herein provide a method of billing a customer based on the electricity usage savings accumulated through demand charge reduction procedures. One embodiment monitors the mitigation of peak loads as they occur, detects and measures incremental changes in demand charge-producing peaks and updates a projection when incremental demand charge changes occur. The demand charge projection may be presented to the customer, aggregated with demand charge projections of other sites, and displayed to increase awareness.

  • Publication number: 20130016106
    Abstract: Methods of generating heat maps of assets using clustering of assets are disclosed. Some methods include receiving a list of assets, assigning the assets to one or more heat range categories based on the status of the assets, assigning assets operating within a zone to a zone cluster, assigning the assets of the zone cluster to category clusters based on the heat range categories assigned to the assets. The positions of the clusters may be calculated for mapping, and may be displayed on a map. Some embodiments of these methods allow a user to quickly detect and locate non-standard assets on a map while standard assets are consolidated to clusters that are less prominent to the user. This leads to minimizing the time required to form responses to de-load hotspots in an electrical grid, minimizing the cost of assets by reducing the need for hardware redundancy, and minimized equipment outages.
