QC Flow Chart
We participate in a variety of trade fairs twice every year .On Electronics Show we discuss with customers
about our products and help them solve questions face to face.We have established contacts with many
potential buyers from other places as America, Australia, Belgium, Israel,Germany, the Netherlands,
1. Q: What is minimal rated capacity?
A: minimal rated capacity is the capacity on 0.2 C discharge till the voltage tapered to 2.0V shall be measured after rested for 30min then finish standard charge.
2. Q: What is internal impedance?
A: Internal impedance is measured at AC 1KHz after 50% charge.
3. Q: What is standard charge?
A: Charging shall consist of charging at a 0.2 C constant current rate until the cell reaches 4.20V. The cell shall then be charged at constant voltage 0f 4.20 volts while tapering the charge current Charging shall be terminat ed when the charging current has tapered to 0.02 C. Charge time:Approx 6.0h,The cell shall demonstrate no permanent degradation when charged between 0℃ and 45℃
4. Q: What is standard discharge?
A: Batteries shall be discharged at a constant current of 0.2 C to 3.0 volts @20℃±5℃. If no otherwise specified, the rest time between Charge and Discharge amount to 30min.
5. Q: What is overcharge?
A: After normal charge, test the batteries’ initial state and capacity. Charge to 10.0V at 3C, then charge at CV mode to 0.01C. Observe battery’s variation of appearance.
6. Q:What is over discharge?
A: After normal charge, test the batteries’ initial state. When the batteries are normal, Discharge to 0V at 0.5C. Observe battery’s variation of appearance.
7. Q: What is external short-circuit?
,A: After normal charge, test the batteries initial state, Keep the battery into explosion protection cover, short- circuit the positive and negative terminals directly (general resistance shall be less than or equal to 50mΩ). Sto p the test when the temperature falls to 10℃ lower than the peak value. Observe the variation of the batteries’ appearance and temperature.
8.Q:How are chargers selected? A:Selecting principles of chargers is as below: (1)Voltage should be regulated by the safest voltage of chargeable cell * n (make the Lithium iron phosphate as 3.6 V and Ni- Co- Mn as 4.2 V); (2)Current should be limited by the safe current of chargeable cell, and the customers’specific requirements also should be considered. (3)If above 120W,chargers with aluminum alloy cooling fin or cooling fan will be suggested. (4)If under 60W,chargers with plastic shell will be suggested.
