Lithium Ion Battery Pack Attention:
Prohibition short circuit
Never marke short circuit cell.It generates very high current which
causes heating of the cells and may cause electrolyte leakage are
The Li-Fe tabs may be easily short-circuited by putting them on
Such outer short circuit may lead to heat generation and damage of
An appropriate circuitry with PCM shall be employed to protect
accidental short circuit of the battery pack.
Notice for Designing Battery Pack
Battery pack should have sufficient styength and the Li-Fe cell
inside should be protected from mechanical shocks.
The Li-Fe cell should be fixed to the battery pack by its large
No cell movement in the battery pack should be allowed.
No sharp edge components should be insides the pack containing the
Spot welding is recommended for Li-Fe tab connection method.
Battery pack should be designed that shear force are not applied to
the Li-Fe tabs.
If apply manual solder met hod to connect tab with PCM.below notice
is very important to ensure battery
◆·The solder iron should be temperature controlled and ESD safe;
◆·Soldering temperature should not exceed 350℃;
◆·Soldering time should not be longer than 3s;
◆·Soldering times should not exceed 5 times,Keep battery tab cold
down before next time soldrictly g;
◆·Directly heat cell body is strictly prohibited,Battery may
damaged by heat above approx.100℃.
Battery pack should be designed not to generate heat even when
leakage occurs due to mishaps.
1)Isolate PCM (Protection Circuit Module) form leaked electrolyte
as perfectly as perfectly as possible.
2)Avoid narrow spacing between bare circuit patterns with different
voltage.(Including around connector)
3)Li-Fe battery should not have liquid from electrolyte,but in case
if leaked electrolyte as possible touch bare circuit
patterns,higher potential terminal material may dissolve and
precipitate at the lower potential terminal,and may cause short
circuit,The design of the PCM must have this covered.
Notice for Assembling Battery Pack
Shocks,high temperature,or contacts of sharp edge components should
not be allowed in battery pack assembling process.
