Lithiumate™ Cell Boards for large prismatic cells
Standard Cell Boards matched to large Li-Ion cells
Cell board of K2 prismatic.
|
- One Cell Board per cell: a Cell Board is mounted to the terminals of a single cell, any arrangement
- Reliable mechanical mounting and direct electrical connection
- A single communication wire is used between adjacent cells in a bank
|
- Possible bank arrangements:
- Two-cell bank: use a "positive end" and a "negative end" cell boards
- Three or more cell bank: use a "positive end", n-2 "mid-bank", and a "negative end"
- Right angle connectors are standard on end boards. Versions with straight connectors or without connectors are available with quick turnaround
- With right angle connectors - requires a slight extra mounting space beyond the cell bolts
- With straight connectors - requires significant extra mounting space beyond the cell bolts
- Without connectors (cables to the BMS controller are soldered directly to the cell board) - requires no extra space beyond the cell bolts
- For example, part number: 1PR0064M:
- 1 = Cell Board
- PR = Prismatic
- 0064 = 64 mm max terminal spacing (center-to center spacing of the rings terminals) (available: 53 to 210 mm)
- M = mid bank (available: P, M, N)
Parts in bold are stocked.
See the wiring instructions.
Power connections:
- Connection to the positive terminal of the cell is through the ring terminal on the red wire
- Connection to the negative terminal of the cell is through the ring terminal on PCB
Signal connections:
- Signal connection between adjacent cell boards is through the gray and orange wires (in rev B parts, it is done by soldering a wire between the C+ and C- pads)
- Signal connection to the BMS controller is through two 2-pin connectors, one to the positive end board (red and black wires) and one to the negative end board (white and green wires)
