Filed:

Sep 30, 2004

Appl. No.:

10/955020

Inventors:

Brian C. Large - Pueblo CO, US

Assignee:

The Water Company LLC - Pueblo CO

International Classification:

H01H 33/59
H02J 1/00
B01D 35/06

US Classification:

307115, 307 82, 210748

Abstract:

A system for controlling the operation of conductive plates immersed in an aqueous solution, such as in water treatment applications. The system allows independent control of the current sourced or sunk by each of a plurality of plates. The system also allows each plate to be placed in a high-impedance state in which no appreciable current is sourced or sunk by the system. A plate or a group of plates is controlled by a control module which interfaces to a central controller such as a personal computer or a programmable logic controller. Multiple control modules can be added to a system to support multiple plates, each of which can be controlled individually from the central controller. Each control module is also capable of sensing voltage and current at its corresponding plate and providing that information to the central controller.

Abstract:

An electrode for use in a deionization apparatus includes a conductive material that is in a granular form and is arranged in a layer that is defined by a first face and a second face. The electrode includes a substrate that is disposed against the first face, and a first member that is disposed against the second face and is formed to permit a fluid to pass through the first member and into contact with the granular conductive material to permit absorption of ions by the granular conductive material.

US Classification:

204520, 204630

Abstract:

A method and system for treating a fluid includes an electrode with an outer housing having openings in a side wall thereof, a granular conductive material encapsulated within the outer housing, and an electrical terminal located at least partially within the outer housing and in electrical communication with the granular conductive material, wherein the openings are configured to permit ions in a fluid to be treated to pass there through so as to come into contact with the granular conductive material. The system includes a treatment tank and electrodes within the tank being charged to differing polarities by a voltage source. The method includes applying a first polarity to at least one electrode, oppositely charging one or more of other spaced apart electrodes, and flowing the fluid within the space so as to treat the fluid.

International Classification:

H01M 10/42
B60L 58/10

Abstract:

Systems and methods are provided for a battery management system (BMS) having a protection circuit. In one example, a vehicle battery system may include the BMS, the BMS including a cutoff circuit coupled to a short-circuit protection circuit, and a battery pack, wherein the short-circuit protection circuit may include a diode array, cathodes of the diode array being coupled to a positive terminal post of the battery pack and anodes of the diode array being coupled to a negative terminal post of the battery pack. In some examples, the cutoff circuit may further be coupled to a reverse bias protection circuit including a switchable current path arranged between a control input of the cutoff circuit and an output of the cutoff circuit. In this way, the vehicle battery system may be protected from unexpected voltage conditions via the BMS redirecting and dissipating excess current away from the cutoff circuit.

Abstract:

Systems and methods are provided for a battery management system (BMS) having a protection circuit. In one example, a vehicle battery system may include the BMS, the BMS including a cutoff circuit electrically coupled to the protection circuit, and a battery pack, a positive supply line of the battery pack being electrically coupled to the cutoff circuit, wherein the protection circuit may include each of an input electrically coupled to a control input of the cutoff circuit, an output electrically coupled to an output of the cutoff circuit, and a control input of the protection circuit electrically coupled to the output of the cutoff circuit. In some examples, the protection circuit may further include a low-current leakage transistor configured to maintain the cutoff circuit in an OFF state upon detection of a reverse bias voltage. In this way, the protection circuit may mitigate unexpected switching ON of the cutoff circuit.
