Agilent MCCD System Capabilities

The Agilent Multi-Cell Charger/Discharger (MCCD) System has been designed to address the unique requirements and needs of lithium-ion cell manufacturing. The Agilent MCCD System can accurately charge, discharge, and measure lithium ion cells. It consists of an Agilent E4370A Multi-Cell Charger/Discharger mainframe with up to four Agilent E4374A 64-Channel Charger/Discharger cards. When fully loaded each mainframe has 256 input/output channels. Mainframes and modules can be combined in different configurations to form a low cost, high performance cell charge/discharge station in a cell manufacturing process.

The following figure is a simplified block diagram of the Agilent MCCD System. It is followed by a brief description of the system’s basic as well as advanced features.

The pin numbers of the Digital I/O connector appear on the screen. Refer to Figure 2-2 for the physical locations of the pins. Note that the two pins on each end of the connector are the Common connection for any pins that are configured as grounded outputs All pins do not have to be configured in the same way. Some can be used as isolated outputs while others are single-ended I/O. Functions can also be mixed, with some pins being general purpose Digital I/O while others have a specific purpose. Chapter 2 under “Digital Connections” provides further information about the purpose and application of the digital I/O signals. Any pin can be configured for selections 1 through 7. The common ground pin is the return for these selections Mixed Configuration Example Accessing CalibrationAgilent MCCD User Interface Browser SettingsDescription PC RequirementsUsing the Interface AccessLocalization Using the Agilent MCCD Measurement Log Utility Transfers all of the logged data in the order that it was logged A Cell Forming Overview Programming OverviewFigure 5-1.
