Li-ion cylindrical rechargeable battery
The following caution and warning should appear in manuals and/or instructions for users, especially at the point
of use.
Proper use and handling of lithium-ion batteries
1. Electric car, charger and battery pack design considerations
1.1 Charging
1.1.1 Cell must be charged with constant current-constant voltage method. Charging voltage must below
4.20V/cell and the charging cut-off current is greater than or equal to 1/20C. Even if the charge could be
out of order, charge voltage of charger should not be above 4.23V/cell to avoid over-charging. Cell life
will be shorten by charging voltage above 4.20V.
1.1.2 Charger should be equipped with a complete charging detection device including the timer inspection,
current and open circuit voltage to detect the current state of charge. When one of the detection such
as timer, current and voltage detected the full charge, charge should be completely cut off the charging
circuit, avoid produce turbulence.
1.1.3 Charger should start charging at temperature range 0ºC~ +45ºC (see spec 3.5).When the cell temperature
exceeds this range, it should be placed in the battery temperature to teach the above range before
recharging.
1.1.4 For cycle life, use the normal charging or trickle charging method and minimize the fast charge.
1.2 Discharging
1.2.1 Discharge end voltage must be over 2.5V.
1.2.2 Discharge temperature range should be -20ºC ~ +45ºC (see spec 3.8). If surface temperature exceeds
55 degrees, the discharge must be stopped.
1.3 Storage
Any storage, cell should be in low humidity (less than 70%RH), no corrosive gas atmosphere area. And there is
no press and condensation on the cell. Best temperature range -20ºC~20ºC. The capacity of cell is 25%-35%
SOC.
When stored within 1 month: -20ºC ~ 45ºC
When stored within 3 months: -20ºC ~ 35ºC
When stored within 12 months: -20ºC ~ 20ºC
1.4 Precautions on battery pack design
1.4.1
Battery pack Shape, Mechanism and Material.
The battery pack should be designed to ensure that it can not be charged by an unauthorized charger.
The battery pack should be designed to ensure that it can not be connected to unauthorized equipment
and equipment; both ends of the battery pack should be designed to avoid short circuits or positive
and negative The battery pack design should have anti-static function and can prevent the dust , The
battery should be designed so that even if the battery leakage occurs, the electrolyte can not reach the
protection circuit board; battery design should ensure that the battery is fixed in the battery pack, can not
move; battery pack in the structure should ensure that The use of materials such as double-sided tape
and rubber should verify its flammability; welding mold should be sealed with glue; if the welding die in
the sealed when the welding of the mold can not be used, The use of ultrasonic welding method, for the
emergence of any defects, God does not bear anything Either.
