KNOWLEDGE & CREATION
Battery Division
▣ Formation refers to the activation process that
completes the characteristics of a secondary battery after
the secondary battery assembly is completed.
K&C Co., Ltd. is the first in the world to apply a pulse type,
enabling groundbreaking formation control.
- The charging time is more than twice as fast as the
existing charge/discharge process.
(Tact Time 50% ~ 65% reduction effect)
- Securing battery stability during high-speed
charging (extension of battery life by 12 to 31%)
- High current resistance is secured by applying a
high current with a pattern similar
to that actually used in EV vehicles.
· Charging result
Experimental condition :
Pulse 1.0C / Pulse 1.56C / Normal 1.56C
- In general, the chemical conversion process is
carried out at 0.4C ~ 0.6C, and charging is possible
without damage at more than twice the charging
speed when charging with Pulse Type.
▣ Supports Direct DCIR method / Excellent
precision compared to other domestic and
foreign equipment.
· DCIR measurement method
1. constant voltage
2. Discharge in CC (constant current) mode under
class conditions
3. ΔU3(drop voltage) measurement
4. DCIR calculation
· DCIR measurement important technology
1. Accuracy of current capability and current control
corresponding to Class (1 to 4)
* Current control (Tr/Tf time and charge/discharge
switching characteristics)
2. ΔU3(drop voltage) record interval technology to measure
