Dynamic allocation of power modules for charging electric vehicles is described herein. The charging system includes multiple dispensers that each include one or more power modules that can supply power to any one of the dispensers at a time. A dispenser includes a first power bus that is switchably connected to one or more local power modules and switchably connected to one or more power modules located remotely in another dispenser. The one or more local power modules are switchably connected to a second power bus in the other dispenser. The dispenser includes a control unit that is to cause the local power modules and the remote power modules to switchably connect and disconnect from the first power bus to dynamically allocate the power modules between the dispenser and the other dispenser.

Dynamic allocation of power modules for charging electric vehicles

Dynamic allocation of power modules for charging electric vehicles is described herein. A power cabinet includes multiple power modules that each are capable of supplying an amount of power to a dispenser. Multiple dispensers are coupled with the same power cabinet. A first power bus couples a first dispenser and switchably connects the power modules to the first dispenser; and a second power bus couples a second dispenser and switchably connects the power modules to the second dispenser. The power cabinet includes a control unit that is configured to cause the power modules to switchably connect and disconnect from the first power bus and the second power bus to dynamically allocate the power modules between the first dispenser and the second dispenser.

A first dispenser receives a request to initiate charging service for charging an electric vehicle. The first dispenser determines an amount of power that is available for the charging service for charging the electric vehicle including determining an availability status of multiple power modules that are located in the first dispenser and a second dispenser. The first dispenser determines whether the available amount of power is enough to meet a requested or determined amount of power draw of the electric vehicle. If the available amount of power is not enough to meet the requested or determined amount of power draw of the electric vehicle, and if there is at least one of the power modules that is available, the first dispenser requests allocation of the available power module and charging service commences.

A safety supervisory module (SSM) of an electric vehicle charging station that controls flow of current from the electric vehicle charging station to an electric vehicle. The SSM includes a set of two or more processors to control operation of a contactor control circuitry of the SSM to open and close a set of contacts of a set of power supply lines to control flow of current from the charging station to an electric vehicle. Each processor independently determines whether an unsafe condition exists and asserts a relay enable signal to the contactor control circuitry only when an unsafe condition does not exist. The contactor control circuitry generates a current to energize a relay to close the set of contacts responsive to the relay enable signal being asserted by each and every processor of the set of processors, and inhibits closure of the set of contacts or opens the set of contacts to prevent electricity from flowing between the charging station and an electric vehicle when any of the set of processors is not asserting the relay enable signal.

Detection of the flow of a fluid, and also measurement of the flow of a fluid, is provided by feeding the fluid flow through a cylindrical chamber to form a cyclonic circulation of the fluid in the chamber. A movable member is moved by the fluid flow. As one example a ball rotates around the inside of the chamber and the passage of the ball detected, at a particular position. An alternative is an annular member also rotated. There can be an optical detection or electronic detection. Output signal can be generated by the movement. Such signals can be processed to give flow rates. The chamber is positioned in a by-pass flow line, with the flow rate of the by-pass related to the total flow.

This invention relates to a sight targeting and range finding device which permits the bow to be aligned properly to a destined target. The bow sight-range finder device can be programmed by the user to select the proper targeting marker for a given distance and also allow selection of range finder markers that can be programmed to be used in conjunction with the targeting markers. When the range finder is used by the archer, the site targeting markers are automatically positioned. The bow sight includes a control which provides interface between the bow sight electronic circuitry and the archers fingers on the hand holding the bow.
