1 General Information 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 channe

1 - General Information Basic Functions ♦ Charger – The Agilent MCCD can deliver accurately controlled current and voltage into a cell for proper forming. Each cell is independently paced through the cell forming sequence. This means that some cells can be charging and others discharging if they are at different points in the sequence. ♦ Discharger – The Agilent MCCD can draw accurately controlled current from a cell for both forming and capacity measurement. ♦ Measurement – The Agilent MCCD can

Agilent E4371A Powerbus Load Rear Panel External Power Source For the charging cycle, each Agilent MCCD mainframe requires an external dc power source to power the cells. The external power source connects to the power bus terminals on the back of the mainframe. It must be rated at 24 volts and be able to source 125% of the required cell charging power. For example, to provide the cell c

1 - General Information Additionally, a single supply of sufficient amperage may be shared among multiple mainframes that are connected to a common power bus - provided that the total current can be supplied while meeting the voltage specification at the power bus terminals at the rear of the Agilent MCCD. NOTE: If the external dc power source has an overvoltage protection circuit, it must be set higher than 30 volts to avoid the possibility of shutting itself down during the discharge cycle. Mu

General Information - 1 The maximum power required for such a system is 25.6 kilowatts. A single power source of sufficient total amperage may be shared among multiple mainframes connected to the power bus, provided the total current can be provided while meeting the 24 volt dc input requirement at the power bus terminals on the rear of each mainframe. Multiple paralleled 24 volt dc sources may be used in place of the single 24 volt, 25.6 kilowatt dc source shown in the figure. To achieve improv

1 - General Information Capacity Measurements Amp-hour capacity - the Agilent MCCD determines amp-hour cell capacity by making calculations based on continuous current measurements. During charge, every time the Agilent MCCD makes a measurement, it calculates the actual incremental amp-hours put into the cell during each measurement interval by multiplying the measured current times the measurement interval. It then adds this incremental amount to the accumulated amp-hour value to determine the

Summary of the content on the page No. 17

General Information - 1 The Agilent MCCD measures the dc cell resistance by first disconnecting the charge/discharge circuits from all cells. A pulse generator in the Agilent MCCD mainframe is connected sequentially to each cell. The pulse generator passes a short-duration pulsed current through each cell while the measurement system digitizes the cell voltage and current using a high accuracy, high-speed A/D converter. Using proprietary algorithms to calculate the change in voltage relative to

1 - General Information The comparison test to see if the ΔV, ΔI, and Δt values have been exceeded is done at the end of each measurement interval, so the fastest rate at which records can be written into the data buffer is the measurement rate of the Agilent MCCD. Any combination of events can be specified, so that a data log record is written into the data buffer when any of the events occur. Each record in the data buffer contains the following information: status (including CV/CC and step nu

General Information - 1 External Digital I/O Protection Functions The Digital I/O subsystem on the Agilent MCCD can be configured to provide protection capabilities. These digital I/O signals operate independently, so that if there is a problem with the computer or the LAN connection the protection functions of the Agilent MCCD are not compromised. As explained in chapter 2, the 16 digital I/O signals can be individually configured to provide one of the following protection functions: External

1 - General Information Application Programming Interface (API) The application programming interface runs under Windows 95 or Windows NT 4.0 using supplied C- language function calls. These function calls are documented in chapters 5 and 6, and provide the most comprehensive method of controlling the Agilent MCCD. The API interface is the preferred method of control when the Agilent MCCD is connected to a remote computer as part of an automated manufacturing process. Web Accessible Agilent MCCD
