There shall be no such defect as flaw, crack, rust, leakage, which may adversely affect
commercial value of battery.
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 very dangerous.
The Li-Fe tabs may be easily short-circuited by putting them on conductive surface.
Such outer short circuit may lead to heat generation and damage of the cell.
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 surface area.
No cell movement in the battery pack should be allowed.
No sharp edge components should be insides the pack containing the Li-Fe cell.
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.
