Patent number: 10312484Abstract: An apparatus and method of mounting storage batteries are presented in which batteries in multiple tiers may be easily accessed for installation and servicing. A battery cabinet or relay rack has provision for multiple tiers of batteries spaced so that batteries may be inserted in each tier. The batteries are supported by a tray or other structure so that they are positioned to permit top access to the battery terminals mounted on the front or front to surfaces of the battery. Tiers are positioned further from the front of the relay rack as the height of the tier increases.Type: GrantFiled: February 20, 2015Date of Patent: June 4, 2019Assignee: C & C Power, Inc.Inventors: N. William Conrardy, Michael Osko, Christopher D. Heinz

Patent number: 10302707Abstract: A system and method for monitoring the status of a system of battery strings is described. The battery string current is measured by a current sensor urged into contact with a metallic element in which the battery string current is flowing. The time history of the battery string current and voltage is interpreted to determine whether the battery string is discharging, charging or in a fully charged state. A moving average current in the charging state is used to establish a threshold for determining whether a thermal runaway condition exists. The moving average is maintained at the value that existed at a time when the battery string has been disconnected from the system current bus.Type: GrantFiled: January 19, 2017Date of Patent: May 28, 2019Assignee: C & C Power, Inc.Inventors: Eric Gach, William Fechalos, N.

Patent number: 9799876Abstract: Storage batteries connected in series in an uninterruptable or back-up power supply system may have voltage potential differences between exposed terminals or conductors that exceed safety limits. A demountable insulating shield having apertures may be positioned so that the series string may be broken into a plurality of series sub-strings having a lesser potential difference has a cover over the aperture through which the series string configuration may be connected and disconnected. The cover may be an insulating material removably fastened to the insulating shield or a sliding cover that is captivated to the insulating shield. When the series string has been divided in to the sub-strings, the insulating shield may be demounted from the structure housing the batteries so that the batteries or their connections may be serviced.Type: GrantFiled: November 1, 2016Date of Patent: October 24, 2017Assignee: C & C POWER, INC.Inventors: N.

Patent number: 8558712Abstract: A system and method for monitoring the status of a system of battery strings is described. The system includes a current sensor for each of the battery strings, and a controller configured to compare the measured current with criteria to determine whether the battery is in a thermal runaway state. Prior to entering the thermal runaway state the battery current characteristics may indicate other less serious states. Warning messages are provided for selected events, and the battery string is disconnected from the remainder of the system when a thermal runaway state is encountered. The system may provide a local indication of status and may also interface with a communications network to provide for remote monitoring.Type: GrantFiled: June 3, 2010Date of Patent: October 15, 2013Assignee: C&C Power, Inc.Inventors: William Fechalos, N.

Patent number: 8558508Abstract: A system and method for monitoring the status of a system of battery strings is described. The system includes a current sensor for each of the battery strings, and a controller configured to compute the average current from the measured currents. The state of the battery system is determined as being fully charged, discharging or charging, and the individual battery string currents are compared with the average measured current to determine if the currents are within a threshold value. An alarm indication is provided when one or more of the currents exceeds a threshold difference. The system may provide a local indication of status and may also interface with a communications network to provide for remote monitoring.Type: GrantFiled: May 8, 2008Date of Patent: October 15, 2013Assignee: C & C Power, Inc.Inventors: William Fechalos, N.
