Cell board, custom, multiple cells

1XXxxxx, custom Cell Boards for multiple cells

Each of these custom cell boards handles a number of cells.

Description

• Custom made to fit a number of cells
• One Cell Board per a group of cells in series (and, if required, in parallel as well)
• These cell boards require a BMS controller to form a complete BMS

Applications

These cell boards can be used with a variety of cells, in a variety of configurations, to meet your special requirements.

Custom cell board for 7 pouch cells (left) and 4 small cylindrical cells (right).

Selection

Banking

A bank can be handled in one of two ways:

• Full bank: a single cell board handles the entire bank
• Split bank: 2 or more cell boards handle the bank:
  • A positive cell board on its most positive cell
  • A negative cell board on its most negative cell
  • Zero or more mid-bank cell boards on any remaining cells

Bank	Type	Range	Cable to BMS board	Wires to adjacent cell boards
Full	Full-bank	Handles the entire bank	Through two 2-pin connectors	N.A.
Split	Positive End	Handles the post positive portion of the bank	Red and black wires through a 2-pin connector	A single wire to the next cell board
	Mid-bank	Handles a central portion of the bank	N.A.	Two single wires, one to the previous cell board, one to the next one
	Negative End	Handles the post negative portion of the bank	White and green wires through a 2-pin connector	A single wire to the previous cell board

Specifically:

• When a single cell board handles the entire bank, a "Full bank" cell board is used
• When 2 cell boards handle a bank, a "Positive end" cell board is used at the most positive end of the bank, and a "Negative end" one is used at the most negative end of the bank
• When 3 cell boards handle a bank, a "Positive end" cell board is used at the positive end, a "Mid bank" one is used in the middle, and a "Negative end" one is used at the negative end
• When n cell boards handle a bank, a "Positive end" cell board is used at the positive end, n-2 "Mid bank" ones are used in the middle, and a "Negative end" one is used at the negative end

Connectors

Right angle connectors are standard on full bank and end boards. Cell boards with straight connectors or no connectors are also available

Part numbering

Part number: 1ZZ1234B:

• 1 = Cell Board
• ZZ = Assigned by Elithion for each custom board
• 12 = Number of cells in series (available: 2 to 16)
• 34 = Assigned by Elithion for each custom board
• B = full bank (available: B = full bank; M = mid-bank; P = positive end; N = negative end)

Ordering

Prices

The price of these Cell Boards is proportional to the number of cells in series they handle, plus some cost for the components at the end of the bank.
