CAR, CHARGER AND BATTERY PACK DESIGN CONSIDERATIONS
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 0℃ ~ +45℃(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 -20℃ ~ +55℃(see spec 3.8). If surface temperature
exceeds 70 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 -20℃~20℃. The capacity of cell is
25%-35% SOC.
When stored within 1 month : -20℃ ~ 50℃
When stored within 3 months : -20℃ ~ 40℃
When stored within 12 months : -20℃ ~ 20℃
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.
