Series 5300 Lithium Cell Formation System

3 Generations of Lithium Formation Systems Series 5000 Series 5200 Series 5300

Series 5300 New Features Individual progression of each cell through the complete formation process. Higher current 2.5 amps. Up to 128 steps for each formation procedure. Cycling capability. Data collection during the formation. AC impedance (1 KHz) available as an option. Reduced size and complexity for UPS backup. Lower cost per channel (<12%).

Overall System Layout

Electronics Hardware (1) Rear view showing interface connections to cell fixture Front view showing filtered air inlet and guarded AC power switch

Electronics Hardware (2) 32 cell controller board. From left to right, cell interface connectors, output current fuses, isolation relays, heat sink,charge/discharge relays, electronic components, dc power input. Internal view, with 8 x 32 cell controller boards in top section, power supplies in bottom section and air filter on hinged door. All service access is through front door only.

Electronics Hardware (3) Interface cable for 4 cells, with 37 pin DIN style connector. Maximum cable length 3 m. Interface cables to cell fixture exit the rear of the electronics cabinets

System Functions (1) Charge and discharge at up to 2.5 amps. Charge CC to voltage limit, then CV to current limit. Charge can end on time, voltage current, amp-hours, and others including faults and safety conditions. Discharge at CC. Discharge can end on time, voltage, amp-hours, and others including faults and safety conditions. Each cell progresses individually through the formation, thus at any one time some cells can be in charge and some in discharge.

System Functions (2) Data can be recorded at intervals of 1 minute or multiple thereof. Data recorded includes voltage time, current, amp-hours, watt-hours, cycle no., and step no. Each cell has its own data file. Each cell tray has a summary data file. Up to 128 steps in each formation procedure. > 1000 cycle capability. Each group of 128 cells can be running a different formation procedure.

Technical Specifications (1) Voltage measurement range: 0 to 5.0 V Maximum charge voltage: 5.0 V Minimum discharge voltage: 2.0 V Voltage accuracy: +/- 5 mV Maximum charge current: 2.5 A per cell (limited to 400 A maximum per 256 cell cabinet) Maximum discharge current: 2.5 A Current accuracy: +/- 2.5 mA

Technical Specifications (2) Capacity accuracy: +/- 2.5 mAh at the “C” rate Time resolution: 500 mS Data recording rate: minimum 1 minute or multiple thereof Operating temperature: 5 to 35 deg.C at full current AC power input: 180 to 264V, or 360 to 500V, 3 phase, 2.5 KW per 256 cell cabinet

Software Maccor formation software is 32 bit, and normally runs under Windows 98. The control program is virtually identical to our laboratory test system software, and has a high level of maturity. Around this is a shell program that functions as an interface to the formation system hardware.
